First, a few concepts: classification.
Sleep】 【,】 【sleep windows of these two concepts are defined in the operating system. .
Machine and system level, the ACPI state and more detail, please see the excerpt's content.
Conclusion:. .
Power consumption says.
Normal operation> sleep> Sleep = Shutdown. .
S0 > S1 > S2 > S3 > S4 = S5。.
Constantly opening the case of electricity, S4 and S5 is the need to power-hungry state, but power consumption is small. .
About content excerpted from wiki encyclopedia "advanced configuration and power interface (ACPI)" entry, and are interested can go take a look at more details:.
Global state (Global System States). .
ACPI specification defines a single compatible ACPI computer systems can have the following seven States (the so-called global state):.
'G0 (S0) normal operation:. .
The computer's normal working condition-the operating system and application is running. CPU (s) implementation of the directive. In this State (i.e., no sleep into G1), the CPU, and like a hard drive, DVD drive, these devices can be repeated entry and from low-energy state of the back, called C0-Cn and D0-D3. (For example, a laptop computer, when you use the battery run time usually turn off all currently unused device; some desktop computers also do so to reduce noise. )。.
G1 sleep. .
Broken down into from S1 to S4 four State. System from a State of being awake to G0 (called latency) by short is S1, S2 is shorter and S3, S4 is too short.
S1:. .
Maximum power consumption in sleep mode. All the registers of the processor are refreshed, and the CPU stops the execution of the instruction. The power of the CPU and memory has been maintained and if the equipment is not in use it will be stopped. This pattern usually refers to power standby or simply called POS, particularly in BIOS settings interface. Some of the new computer is no longer support the old S1; computer support on the S1 may be larger than the S3 is good.
S2:. .
A deeper than S1 sleep state, but has no power to the CPU; however, this mode is not being used.
S3:. .
In the BIOS is called "the memory (Suspend to RAM/STR) in Windows XP and later versions of Windows, some Linux release called" standby (Standby) on Windows Vista and Mac OS X are called "sleep" (Sleep), although the ACPI specification only refers to the term "S3" and "sleep" (Sleep). In this mode, the main memory (RAM) still have the power supply, even though it is almost the only has a power supply of the original. . (Mentioned in the specification is quite similar to the S3 and S2, only more of the components in the S3 state, power will be turned off.) S4 compared to S3 has two advantages for; computer restart recovery process is faster than the first Second, if any running applications (to be an open document, etc.) have private information on the inside, this information will not be written to the hard disk. However, the system can not be awakened such as during a power failure when the cache may be flushed to prevent data corruption. .
S4：。.
In Windows, called sleep, in the Mac OS X, called safe sleep, also known as linked to the hard drive, although the ACPI specification only refers to a term S4 (main article: Hibernate (OS feature)). In this state, all the contents of main memory is stored in nonvolatile memory, such as hard disk, the current state of protection of the operating system, including all applications, open documents and so on. . This means that after recovery from the S4, the user can be restored to original working condition, the method and S3 is the same.. .S4 and other S State is quite different, in fact more similar G2Soft Off State and G3 Mechanical Off State, rather than in S1-S3. S4 state system also may enter G3 (Mechanical Off) status, and keep status information when S4. so it can be restored to a previous state after the turn off the power.
G2 (S5) Soft Off. .
G2, S5, and Soft Off is the same name. G2 and G3Mechanical Off is nearly the same, but some parts still charged, so that your computer can still be a keyboard, a clock, modem (phone wake), LAN (wake on LAN) as well as the USB device. [1] at the start system restore from the G2 to G0 normal mode of procedure, whether it is a Mechanical Off or G2 G3 are run startup programs to boot the operating system.
Turned off because the power needed, 1, motherboard not power, in order to maintain the keyboard, mouse, network card, etc. Automatic wake-up function must be kept in a low-power state. .
2, power supply, regulated exchanges should be called to DC power converter. in low power state.
Above. .
Result of the tragic power consumption.
In order to save power resources, please note that disconnect the power after shutdown, not just the computer, disconnect all electrical power shutdown is a good habit. Intel introduced a new one mobile computing platform, Centrino 2, the order to meet its overall platform development, have launched the Celeron dual-core T1600, Pentium Dual Core T3200, Core 2 Duo T5800 three new processors, corresponding to three different levels of consumption.。.
Celeron Dual-Core T1600. .
First, we introduce the low-end user launched the "dual-core Celeron T1600". From naming, T1600 is Intel has launched the low-end T1400, Celeron dual core T1500 two after a delivery is a Celeron series dual-core processor, but by following CPU-Z screenshot the overall argument is more like a Pentium dual core, 1 MB L2 cache is T1500 512KB T1400, more of the doubled, and T2000 series, Pentium dual-core, but the software was clearly demonstrated by the words "T1600". . .66 GHz, lower than the previous two products, which is why? The main intent of the original release is the T1600 with Centrino 2 platform, the motherboard needs to enhance the processor's FSB to 166MHz, 667MHz front side bus to achieve the minimum, then the low-end Celeron Dual Core T1600 came into being. The Celeron dual-core T1600 processor, or using a Merom core, with 512KB * 2 of the secondary cache, but the frequency combination becomes: 166MHz * 10 = 1666MHz. Enhancement of the front-side bus, though slightly lower frequency, performance should still be more than T1400, T1500 to higher than some.。.
Celeron Dual-Core T1600. .
Pentium dual core T3200.
Paragraph to introduce the Pentium dual-core, I believe that many of my friends have seen the detailed evaluation for everyone before we had a used T2410 Pentium dual-core processor, notebook, this T2410 processor has a 2. .0 GHz clock speed, which is the highest frequency of the Pentium series. However, there was a recent Pentium T3200 dual-core processor, but the same frequency of 2. .0 GHz, which is why? The same reasons, but also to meet the Centrino 2 platform, this T3200 dual-core processor also uses 166MHz FSB, 667MHz front side bus, under the same frequency provides better performance. .
# K% b/ M9 N; Q6 M' k/ |: n8 ~8 x。.
Pentium Dual Core T3200. .
Core 2 Duo T5800.
Third paragraph appears in the high-end product is positioning Core 2 Duo processor T5800, the processor and the Pentium dual-core T3200, Core 2 Duo T5750 2 are used. .0 GHz clock speed, but due to the low-end products in the T3200's front-side bus increase to 667MHz, making only slightly larger than twice the secondary cache (1MB * 2) of the Core 2 Duo T5750 does not have significant performance advantages, only forced to launch a 800MHz front side bus with T5800.。.
W Core 2 Duo T5800 First, the difference between bulk and boxed. .
From a technical perspective, bulk and boxed CPU and there is no difference between the nature, at least in the quality does not exist on the merits of the issue. For CPU manufacturers and their products in accordance with the mode of supply can be divided into two kinds, one kind supplied to manufacturers of brand-, another kind of supply to the retail market. Products for the retail market for the most part boxed product, which is part of the bulk products from brand machine manufacturers release as well as agents of the sales strategy. Theoretically, boxed and bulk product in performance, stability, and overclocking potential, there is no difference, but there are certain differences in quality assurance.
In general, the boxed CPU's warranty period is longer (usually three years), and comes with a good quality cooling fan, so often by the majority of consumers. However, this does not mean that there is no warranty CPU in bulk, simply choose the good reputation of the agents, usually can get the regular one-year warranty time. In fact, CPU does not exist in the concept of warranty, maintenance, etc. So at this time limited warranty, so do not worry there will be no bulk water quality standards. .
Second, the CPU market situation — finding out about the real boxed product.
But things are not so simple. Rampant profiteers have even bothered to work effortlessly Remark fees, but rather simply on some bulk directly on a CPU fan with a strong adhesive, but also its reputation, called "genuine authentic", and then just marked on the fan higher frequency of CPU frequency can be really simple! Consumers will open the fan look? Of course not! Unless you are bad fans, but also do not have this courage, because to remove the fan firmly pasted this, CPU is likely to lose your warranty, calling also cause physical damage. .
In order to deceive the public, some traders may also use other clients leave the original fan and packaging, and bulk product, simply is a "seamless". There is no doubt that if the manufacturer does not take the necessary measures, so ordinary consumers almost powerless to do anything about this.
Whether Intel or AMD's CPU, boxed product origin are very worrying. The Intel CPU, for example, most boxed products on the market are counterfeit, and even statistics that more than 75% has been achieved. The so-called fake box is nothing more than two cases: bulk package with the CPU and the original radiator, or direct use of counterfeit and shoddy and the CPU heat sink bonding. In contrast, the latter is more obvious, as a boxed product on the market today almost no real original radiator, its origin is indeed doubtful. .
As for the CPU, AMD has been mainly for the DIY market, boxed product is rare. However, the recent market also appear phony boxed product, its price is slightly higher bulk products, only a one-year warranty, just use the box to mislead the public. In addition, part of the business as a real boxed product to buy and false promises the possibility of a three-year warranty.
In contrast, AMD's current more easily identify genuine boxed it in the plastic packaging and internal fan are affixed bar code, packaging side there is a security laser mark. In addition, since most users do not buy AMD CPU boxed very concerned about it or not, so the relative Intel boxed products, its profiteers less attractive. .
Third, call a spade a spade — how to face the boxed and bulk.
1. Intel CPU. .
Based on the above analysis, you should already understand the boxed product and the difference between bulk products, not to mention the Intel CPU now boxed Maoni many, so individuals are more inclined to direct selection of bulk products. From a user perspective, to buy the boxed product bulk product is most unacceptable. More importantly, counterfeit products often used only boxed 20 $ to poor fan, this time on the CPU even.
Genuine boxed Intel CPU would only use AVC or Sanyo radiator, radiator many of the retail market also has a very good quality, noise control, whether or not less cooling effect. CPU to do the work as long as the heat, then no problem and stable operation was set, but the current production process, the general CPU is a little damaged, the extra time and two-year warranty is not much temptation. .
Of course, this is just my personal consumption patterns. Part of the pursuit of peace of mind of the user may be more inclined to boxed CPU, you should buy. Real Boxed Intel P4 is responsible for the three-year warranty, one year warranty on the so-called boxed product by bulk product counterfeiting. Slightly some pity is that Intel boxed CPU AMD that did not take effective measures to prevent false, we can only be achieved through careful observation of your own to tell. . In addition, call the 800 number and the serial number on the fan control is one of the methods tested, but this is not a panacea. .
2．AMD CPU 。.
Most of AMD boxed CPU fan by AVC, and the three-year warranty. But for overclocking users, generally do not recommend the purchase of boxed product. Step back in terms of, even boxed CPU, if the process causes CPU overclocking damage, but the core of a burned trace, then the time is still without warranty. In general, CPU core overheat nothing more than damage, or physical injury, the real internal fault is very rare, comprehensive cost-effective point of view, the bulk product is undoubtedly superior. The Athlon XP 2500 + (Barton core), for example, bulk products of about 650 yuan, while the boxed product of up to 730 yuan or so.。 If users need to purchase an overclocked, then boxed product may not be wise.
Course, the choice boxed products to make you feel more at ease, after all, not every user will frequent replacement of equipment, then provided a long boxed product quality and stability of the radiator is indeed very attractive, but also from "Remark polished" or even "modified Golden Bridge" intrusion of counterfeit products. .
IV. summary.
Bulk can be described with the boxed product is different. Apply saying: Even if there is reasonable! But do not forget to buy boxed product must be built on the basis of hundred percent genuine, otherwise the risk coefficient greater than the bulk product, because can not see the CPU surface, a lot of business opportunities for fraud and poor quality is a big fan risk.。.
Such as the GeForce 8400M replaced the GeForce Go 7400, HD 2400 is another example replaces X1400. This one to one relationship can ensure comprehensive product line layout, but also for consumers to infer that the general performance level of a new generation of graphics cards. .
Therefore, the video card model in the first digit only represents its availability, means that it uses a relatively new technology, but to understand the effectiveness of high and low, mainly to see models of the second digit. In other words, a GeForce 9300M game than GeForce 8600M effectiveness in fact, just a little bit stronger than 8400M.
Graphics card specifications and performance of hot contrast. .
The next generation of HD 3000 series graphics cards have been updated to the 55nm process technology, with lower power consumption and heat output. GeForce 9000M yet continue with the previous generation's 80nm core, but believe that soon will transition to 65nm process.
Even if the same type of graphics card, according to the different suffix, and its performance will be quite different. For example, and compared to 8400M GS, 8400M G the number of stream processors from 16 down to 8, was canceled PureVideo HD HD video acceleration performance and high-definition player in the game's performance will be greatly reduced and so (click here for more more). In addition, 8600M GT has 32 stream processors, 8600M GS is twice the gaming performance also significantly improved. .
But even the suffix are exactly the same video card, its actual performance to see if it's video memory type. GDDR3 video memory frequency typically will reach the upper table in the nominal value (1000MHz ~ 1400MHz); while some manufacturers in order to save costs, only featuring DDR2 memory (800MHz), causing the video card performance decrease.
On high-definition video decoding, we would like to add this: even without the help of graphics acceleration technology, Intel Core 2 Duo T5450 processor is completely above the level of the vast majority can be independent of the smooth playback of 1080p HD video, so users with higher processor configuration without demanding the video card with HD acceleration. .
In addition, desktop, notebook integrated graphics in vain, they will have to stand for long battery life and lower calorific value. Performance, although more than one prominent weak, but along with the rapid development of the hardware, now integrated graphics can also be some network games running smoothly (World of Warcraft) and older 88th (shikuangzuqiu 10). Buy books before, you had better on mainstream CPU and video card specifications, otherwise it is very easy to be individual businessmen "hoodwinked". Of course, if you read below, you can skip directly to the next page.
The current Intel mobile processor family ordered from top to bottom are: single-core Celeron - Celeron Dual Core - Pentium Dual Core - Core 2 Duo T5000 Series - Core 2 Duo T7000 Series - 45-nanometer Core 2 Duo T8000/T9000 series. .
However, this does not mean that high levels of processor performance will be stronger, for example, high-performance Pentium dual-core version may go beyond the low-frequency version of the core 2 Duo.
Is well known that the level of a processor's performance is jointly determined by the number of parameters. Based on our testing experience, the performance of these parameters on the processors arranged in descending order of importance are: kernel Architecture "core frequency> secondary cache> front-side bus. .
Now occupy the mainstream market is a 65nm dual-core processors (from Celeron dual-core to core 2 Duo T7000 series), they have exactly the same core architecture — the Merom codenamed microarchitecture. The main difference is that in the low-end processors in the L2 cache and FSB has been streamlined.
Pentium Dual Core T2000 series with an example, many people will subjectively determined: "It's only a secondary cache Core 2 Duo T5000 series of the half, its performance certainly far lower than the Core 2 Duo", this view is one-sided. In fact, because of their same core architecture, the core frequency at this time will play a decisive role. .
Top processor specifications and comparative effectiveness.
Based on our testing experience, the premise of equal frequency, the Pentium dual-core performance to lag behind Core 2 Duo T5000 series of about 5% -10%. Therefore, the high-frequency version of the Pentium dual-core performance will exceed the low-frequency version of the Intel Core 2 Duo, for example, T2370 (1. .73 GHz) performance than the T5250 (1. .50 GHz) better. .
See where you might be asking: "so much so, T2370 T5250 also how do you sell?" here we talk about Intel's product update policy. Simply put, is periodically launch frequency higher new model to replace the old models, so when replacing T2330 T2370, T5250 has long been replaced by T5450, T5550, thereby maintaining the core 2 on Pentium dual-core advantages.
AMD, since the Turion TL series and Athlon TK series of core architecture is relatively old, so the frequency of the same premise, its performance would be slightly behind the Intel processors, but in the low-priced, they are cost-effective is good. .
First of all let's take a look at these two products: the dilemma.
4830 9800GT undoubtedly the emergence of a blockbuster, the two current products are focused on the 799 this price. .
The present evaluation data between default 4830 dominant project more than 9800GT and, if the preset 650MHz 9800GT, 9800GT and most of the advantages of the project, both of which are beyond the limit of time, rather than to the 9800GT 4830, so having both has 3D applications, both of whom do not have one robust statement exactly.
Let's look at the attitude of the two companies (the following are all personal understanding):. .
AMD (ATI): 4830 is to win the 9800GT.
NV: 9800GT better than to consider overall performance from 4830 stronger. .
The actual game play experience to see the two drawbacks:.
A card: Because to AMD (ATI) graphics optimized for small game, plus the AMD (ATI) lack of drive R & D capabilities, leading to A card when playing games minFPS very low, so there is not much fluidity. .
N card: because the design reasons, NV N card open AA performance are very powerful, but A card advantage precisely in AA.
Is that the advantages of these two cards:. .
A card: HD hard decoding puts CPU with low-end users will be able to watch high-definition, because the dynamic range default is full (0-255) so subjectively black very pure, bright colors.
. .
To see the real: the market.
9800GT: 55nm 8800GT because the 9800GT is the vest, the total adds up launch time is more than 1 year, so the product is very rich in non-public board, the design is also very mature. .
4830: because has just launched, so the optional products are very few, most of them are 4850 public Board to streamline product of symbols.
Below, we began to discuss it. .
Again: if I find another AFan, NFan do frivolous arguments, I will regard the plot points, on the contrary, can be very comprehensive, the grounds of the friends I will, where appropriate, the extra points.
-------------------------------------------------- -------------------------------------------------- -------------------------------------------------- ------------。 .
Thank you, as a result of being: the player and the intended machine users compared to most of the 9800GT.
4830 Bing is not the dominant cause of most of the problem because drivers can only hope that ATI in the driver development, especially for new games, and future performance to be out of the game to be better on it. .
This result is currently exploring, if you have users still have their original ideas, welcomed the continued posted instructions.
In addition to the recent price cuts to shrink 899 4850 512M, 9800GT and 4830 that will further pull down prices, higher performance graphics card market was finally about to enter the mainstream, let us look how much money you can not play along most of the times the times Come the day of the game to the classic generation CPU, Pentium Dual Core E5200 has a year to maintain the hot level throughout the year in 2008, E5200 CPU field in the creation of many miracles can not be replaced.。.
Pentium Dual Core E5400 boxed. .
For E5400, if they want to continue to create a classic E5200 performance relatively more difficult. AMDK10 schema multi-core powerful pressure, intel Pentium dual-core can start level continued to develop strong, all depends on the new product's actual performance and E5400 manifested, E5400 exactly and brilliant E5200? what are the aspects of performance upgrade? what the entry level of the current evaluation grade? a a..
Its configuration. .
E5400 standard parameters.
Pentium Dual Core E5400 using advanced 45nm manufacturing process, the specific specifications did not have much difference with the E5200, it is inevitable, 45nm intel entry level is the highlight. 2MB of high-speed secondary cache same terms and E5200. Changes in key parameters appear in the CPU core frequency, there have been significant frequency increase, E5400 frequency has been raised to 2. .7 GHz frequency, the same as the processor FSB 200MHz, frequency increased to 13 terms. .5 X.。.
To make the test more objective E5400, we will be its rival AMD Phenom 8450 triple-core processors and Athlon dual-core 7750, and pull together the previous generation evaluation brilliant E5200, the cross more easily compare their own values reflected in the product. .
The test project into benchmark tests, including comprehensive performance testing, scientific computing capacity test, multimedia performance tests (including the graphics rendering capabilities and video coding capabilities), the game performance test.
● comprehensive performance inspection. .
Futuremark's PCmark series is a focus on integrated performance of CPU testing software through the test of the software can be fully informed of the processor in entertainment applications performance. For Windows Vista operating system, PCmark has been upgraded to a new version of the Vantage, including TV and Movies (video production), Gaming (game) Music (music) and Communications (communications) and Productivity (productivity), and the subkey.
PCMark Vantage tests on we can see, 2. .7 GHz frequency of the Pentium dual-core E5400 E5200 has been more obvious than in the enhancement of performance in all aspects are relatively satisfactory. But paradoxically, in the last of the Productvity (productivity) in the sub-tests, the E5400 instead of the high frequency of the lowest scores, the specific reasons yet to be discovered. AMD compared with the two products can be said that different. .
? Operational performance and test multimedia instruction sets.
SiSoftware Sandra is a very important performance measure of PC software. It recently launched the 2009 version adds multi-core, multi-threading processor support, so that we can better use it to examine the PC's overall performance. This will test the basic CPU instruction set computing power and multimedia performance:. .
Benchmark performance tests.
Operational aspects of the benchmark test to see, Intel Pentium Dual Core E5400 than the E5200 in terms of integer operations rose 1422 points, an increase of 1725 floating point sub-areas, this performance is more evident. Contrast, dual-core Athlon 7750 rival the poor performance of its terms of integer and floating point operations have not even reached 2. .5 GHz frequency E5200 score. But the three-core Phenom X3 8450 performed well, in terms of integer arithmetic than the Pentium E5400 results. .
● DX9 games real test.
Next, we tested the game's performance. We selected a total of 4 popular games, including 2 games and 2 DirectX 9 DirectX 10 games. DX9 games: Left 4 Dead, Call of Duty 5, the test is 1280 * 1024 resolution of unity, the picture is set to high. .
DX9 game testing.
In DX9 game test, frequency, cache sizes, and multi-core embodiment of the more obvious advantages. As can be seen from the test results, the three core Phenom 8450 in terms of Left 4 Dead Call of Duty 5 or better in both performance, and our protagonist E5400 testing at the Left 4 Dead to eat the losses on the number of cores. Call of Duty 5, however the test is more sensitive to the frequency, E5400 with 2. .7 GHz clock speed exploit the advantages of stability, and occupied the second position. .
● DX10 game practice test.
After seeing a DX9 game test 2 then we come to see the test results of DirectX 10 games. The two test games are Crysis and Crysis FarCry2, their unity is set to test the resolution of 1280 * 1024, which set a high screen Crysis, FarCry2 the game screen is the highest, we get the following results: . .
DX10 game testing.
Pentium Dual Core E5400's performance in DX10 games can be very good, only one test in FarCry2 slightly behind with the Athlon dual-core 7750. Others have achieved greater advantage. .
● 3Dmark06 benchmark.
3Dmark06 is more commonly used in a study of software platform gaming performance, then we use it to test it in DX9 mode, 3DMark 06 results. .
3DMARK06 test results.
In 3DMark 06 test, the Pentium Dual Core E5400 CPU scores in terms of whether or platform are leading the way overall scoring. Contrast, the three core Phenom 8450 processor, due to the lower frequency is only 2. .1 GHz, although the number of cores to make up a number of shortcomings, the overall upgrade is still not high. This shows that in DX9 mode, the frequency or impact on performance improvement is more evident. However, operators are all Intel ? Core ? 2 Duo Mobile Processor. .
However, the manufacturing process and internal capabilities gap, prices are also a lot worse.
T9600 2. .8 GHZ 2 level cache 6MB 1066MHZ FSB manufacturing process to support DDR3 45NM 35W maximum power consumption of course, but fever is also powerful, single price of $ 553. .
P8400 2. .26GHZ level 2 cache support DDR3 1066MHZ FSB 3MB 45NM manufacturing technology consumption 25W now universal price is relatively low.
T5800 2. .0 GHz 2 level cache 2MB FSB 800MHZ DDR2 65NM manufacturing technology to support high-34W power consumption is now estimated to quickly eliminated. .
NVIDA video suffix, generally speaking, the same core graphics representative performance gap, the suffix GTX "GT" GS "G.".
nVidia. .
Vanta: literally unknown, according to nVidia, represents a simplified version of the chip. Only in the TNT era there were several surface. So do not more introduced.
Representative: TNT2 Vanta. .
STD: Standard, Standard Edition. No callout.
Pro: can be understood literally, 'strengthen' means, as long as it appears to represent the comparison of the corresponding high-end version of the chip. TNT2 series originally had, last time was in Geforce2 series, ATI has now become almost a patent. .
Representative: TNT2 Pro, Geforce2 Pro.
Ultra: the literal meaning of 'radical, extreme' means. The fact that it did, in nVidia's products, too, as long as the suffix with this guy, the kind of chips must be the most cattle x, the breakdown of the ancient king NV, the basic familiar figure to see it. There are the pronunciation of the word, many people will be issued as 'ultra' but the actual pronunciation is made 'altra'. .
Representative: TNT2Ultra, Geforce2Ultra, GeforceFX5200Ultra, GeforceFX5600Ultra, GeforceFX5700Ultra, GeforceFX5800Ultra, GeforceFX5900Ultra, GeforceFX5950Ultra, Geforce6800Ultra.
MX: literally no, nVida on behalf of the plan is affordable version, the meaning of the general public category, nVidia dedicated. Suffix with its estimated share of the card high above the surface alive. .
Geforce2 MX, representative: Geforce2 MX100, Geforce2 MX400, MX200, Geforce2 Geforce4 MX420, Geforce4 MX440, Geforce4 MX440-8X, Geforce4 MX4000 Geforce4MX460,.
GTS: super-enhanced version of the "Giga-Texel Shader" in the acronym, meaning millions of pixels, the pixels per second fill rate is reached tens of millions more. GTS only first appeared in the Geforce2 products, on behalf of the then most high-end Geforce2. The performance was very scary. Unfortunately, short-lived hero. GTX is now generally the scaled-down, such as. .
Geforce2 GTS, representative: Geforce8800GTS GTS, 8800GTS.
GTX: general can be understood as GT eXtreme, such as the 8800GTX. .
2008 Nvidia launched the prefix for a series of video cards GTX, such as the GTX280 GTX260, cancelled the suffix is the new generation of graphics cards, Nvidia Naming Convention.
Ti: literally means 'Titanium' acronym, which is the space metal 'Titanium', where it appears in general is the representative of the nVidia's high-end version. In Geforce3 in the early and later joined the Geforce2 Ti, the last peak in the Geforce4 series, we must never forget that masterpiece classic-Geforce4 Ti4200. .
Representative: Geforce2, Geforce3 Ti, Geforce3 Ti500 Ti200, Geforce4 Ti4200, Geforce 4 Ti4400, Geforce4 Ti4600, Geforce4 Ti4200-8X.
XT: The word is funny, because the interpretation of the nVidia and ATI's explanation which is entirely inside the naysayers, especially misleading, so the focus to talk about. XT nVidia to say that according to down-version of the mean. In ATI's dictionary which represents the high-end 'eXTreme' why nVidia came up here to give us a word game, teasing a little ATI. .
Representative: FX5600XT, Geforce, Geforce 6800XT GeforceFX5900XT.

ZT: literally unknown, nVidia used to promote Doom introduced to make, based on the XT down-to lower the price again, represents less than the XT's market position, is the series of the most low-end products. .
Representative: GeforceFX5900ZT.
GT: frequency increase version "GeForce Technoloty" the acronym means a super sports car. .
Representative: Geforce6600GT, Geforce7600GT, Geforce8800GT.
SE: A simplified version is only used in the Geforce4 series, the reduced frequency version. Rare. .
Representative: Geforce4 MX440SE, Geforce4 Ti4800SE (4600 of 8X version).
GE: one that is "GAMER EDITION" acronym, that player version; one said to the HD version. GS version personally think that should be optimized from the essence or the GS version. In fact, the low-frequency version of the same graphics core. .
Representative: yingchi 7600GE HD version, yingchi 7900GS HD version.
Ultra Extreme: is the Ultra version of the highest level, is the flagship product. .
TC: shorthand, nVidia TurboCache technology, enables the graphics alone can also be shared memory as the memory. Because the TurboCache leverages the features PCI-Express bus, so only appear in the interface graphics PCI-E 16x.
With: NV-chip performance and low position suffix: ZT. .
LE：‘Lower Edition’的意思，含义和nVIDIA系列基本相同。ATI显示芯片中带有它的就表示比较低端的版本。从Radeon7500时代开始出现。
代表作：Radeon7500LE，Radeon8500LE
SE："Special Edition"的缩写，表特殊版本，主要是显存位宽只有STD版本的一半， 或者像素流水线数量减少（如9800SE），同样是某一系列中的低端产品，如X300S
代表作：Radeon9200SE，Radeon9600SE。Radeon9800SE，Radeon X300SE
Pro：Professional的缩写，‘加强版’的意思，，是XT的管线屏蔽版。但在X100系列及之后就代表着主流版本，如X700Pro，X1600Pro。它是ATI后缀中不可缺少的一个部分，贯穿了ATI命名的始末。
代表作：Radeon9000Pro，Radeon9500Pro，Radeon9600Pro，Radeon9700Pro，Radeon9800Pro，RadonX700Pro，Radeon X800Pro，Radeon X850Pro
XT：ATi的"XT"是"extreme"的缩写，拥有更高的核心频率和显存频率，在X800以后还同时提升了渲染管线的数量
代表作：Radeon9600XT，Radeon9800XT，Radeon X600XT，RadeonX700XT， RadeonX800XT，RadeonX850XT
XTX，X1000系列发布之后的新的命名规则，和GTX一个道理，XT eXtreme
GD2：这里的"GD2"并非代表GeForce系列，而是表示试用了GDDR2显存 ，同理，GD3是表示使用了GDDR3显存
XT PE：‘eXTreme Platium Editon’有就是所谓的至尊版，，X100系列中出现过。主要代表更高的频率。是旗舰产品。
XL，高端系列中的较低端型号，具体可以理解为eXtreme Limited。
GT/GTO：是PRO的降频或者管线屏蔽版，多出现在X5、X6、X7、X8等显卡里面。
HM：HyperMemory，和上面的TC一个道理
PS：ATI计划中的RV670核心显卡产品将成为他们的HD 3800系列，同时ATI将舍弃沿用的GT、XT、PRO后缀形式，完全依靠数字来区分不同定位的产品。数字越大就表示显卡的性能越好。这样的好处就是更加简单易懂，任何人看来都明白。就说现在的HD 3800系列，HD 3870就是RV670XT，而HD 3850就是RV670PRO。尽管产品的最终规格还没有确定，不过我们今后将不再看到后缀出现。以及后来的HD4800系列，HD4870（Rv770XT），HD4850（Rv770pro）。
T6400
一句话，T6400的出现，宣告着45纳米处理器即将全面占领市场，老款的65纳米处理器已经日薄西山。
从今年1月算起，英特尔发布45纳米的移动处理器已经有将近一年的时间了，但一直局限于中高端型号，并没有急于推出所谓的“阉割版”产品。
现在，英特尔终于发布了采用45纳米Penryn架构的中低端处理器：酷睿2双核T6400和奔腾双核T4200。其中T6400用于取代中端市场的T5800，而T4200则用于取代低端市场的T3400。
作为T5800的接班人，T6400在内核架构和制造工艺方面有较大变化，而且支持SSE4.1多媒体指令集，不过由于核心频率、二级缓存和前端总线仍然相同，因此总体性能提升不会太明显。
下面，我们先通过CPU-Z来查看T6400的详细参数：
>
45nm Core 2 Duo T6400 processor specifications.
And the current high-end positioning in the P7350 compared, T6400 core frequency the same, but the secondary cache and a slightly streamlined front-side bus, and power consumption is slightly higher TDP. Based on our testing experience, sort of processor performance in decreasing order is: kernel Architecture "core frequency> secondary cache> front-side bus. .
According to Intel's planning, T6400 processor this level will not be included in the Centrino 2 family, must be a T9000 series p or series of it — in fact, in the future, the Centrino 2 family will P series processor, because their power consumption of only 25W, calorific value smaller, longer life.
Closer to home, here we come to the actual performance of the T6400 test. .
Test: PCMark05, Cinebench.
The first test is the system comes with Vista "Windows Experience Index", which although not the most rigorous test of professional software, but it is the most common users are most likely to accept and understand, and therefore can be used as reference in this article. .
Our current test platform is a newly listed near the new notebook, T6400 processor, GM45 chipset (integrated GMA X4500 display chip), single 2GB DDR2-667 memory and hard drive, 160GB SATA-II CD and DVD burning 5100AGN wireless card.
In the Vista scores, 这颗 T6400 processor has been 4. .9 Points, a medium level. In our previous tests, T5800 and P7350 of the score for 4. .9, We can see the actual performance of these three processors roughly at the same level (of course, P7350's main advantage is low power consumption.) .
Vista system with assessment tools of CPU score: 4. .9.
PCMark05 tests the CPU score: 5002. .
In PCMark05 tests, this books won 4366, where the processor is a subproject of achievements over 5000, which means that the performance for most T6400 users sufficient.
CPU Cinebench R10 test scores: 4050. .
In the specific processor Cinebench R10 testing, core 2 Duo T6400 got 4050, and almost all T5800 and P7350. Below, we present a histogram to show several mainstream mobile processor performance.
Comprehensive performance comparison, product line plans. .
Because the Cinebench R10 test scores have high representativeness, so we take it as a basis to compare to the processor performance.
The following figure we can see, T6400 and T5800 between the actual performance between the P7350, T5800 successors played a good role. The P7350 is also a higher frequency of the P7450 is about to be replaced in order to continue to maintain a certain performance advantages. .
It is worth mentioning that, as a low-end model Pentium dual core T3200 actual performance nor we originally thought, in fact, it is only when compared with P7350 14% performance gap, the gap in everyday applications, is almost imperceptible. Then take into account the T3200 is about to be replaced by T3400, T4200, therefore we consider that the Pentium dual-core series also has a very high price.
Comprehensive performance mainstream mobile processors compared:. .
Finally, we look at the Intel over the last two months of product line planning.
Latest Intel mobile CPU product line plans. .
From the above picture, we see an Intel Celeron dual core from low-end, Pentium dual-core to a high-end core 2 Duo, will have new product launch, but overall performance boost margins are not large.
From the perspective of business operations, but this is just selling off-season promotions; but the consumer, can buy a new processor, of course better, but old users do not envy, because the old section and the Core 2 Duo dual-core compared to only a small increase their performance a little. .
The actual effect of that.
Seat of your pants, do not feel it. .
2 only a 0. .4.
General computer all do. .
CPU and high point, selling expensive,.
Full effect you want to see the graphics card. .
So if the price difference for many wouldn't consider p8600..
Centrino 2, the difference between the performance of CPU. .
T5800 less than T5900 less than less than less than P8600 P7350 P8400.
Do you see P7350 positioning in the middle. .
Their architecture is the same P7350 should be the block version however P8400 performance better than T5 T5 belong to the core, the lowest level of but better than Pentium and racing sheep.
There are longer P system P system can power a 25W T series are 35W. .
Same capacity battery.
P systems with longer time! ! ! ! . .
Notebook T4200 T5800.
Both as processor frequency, 2. .0 G fsb as 800. .
Not the same as the structure, process, instruction sets, the L2 cache.
The most prominent is that, T5800 power consumption, 65nm, support to sse3, secondary cache 2m. .
Small power dissipation PD T4200 45nm support to sse4.1m .1 L2 cache.
As the mature 45-nm process, Intel will gradually over the low-end processors to 45 nanometers, even Pentium dual-core 45nm Penryn core is also used. .
T4200。.
T4200 is a Pentium dual-core T3200 (2. .0 GHz) of the upgraded version of the frequency did not change, still 2. .0 G, front-side bus upgraded to 800MHz, upgraded to 45-nanometer manufacturing process, the core upgrade to Penryn core, upgraded to SSE4. .1 Multimedia instruction set. *? 1 e4 S # Y: Q / p + W7 Q '^ r. .
T6400。.
T6400 is a Core 2 Duo T5800 upgraded version, the frequency did not change, still 2. .0 G, upgrade to 45-nanometer manufacturing process, the core upgrade to Penryn core, upgraded to SSE4. .1 Multimedia instruction set. .
T4000 series processor is positioning the mainstream user market launch of the dual-core product is the 65-nanometer processor T3000 series upgrade products, the use of the 45-nanometer Penryn Core. Among them are the first listed T4200 2. .0GHz clock speed, but the L2 cache in just configured, and before 1MB T3000 series products; whereas it is in front of the bus to 800MHz, and midrange T6000 product fully compatible. But from this location already has the lowest T4200 2. .0GHz clock speed, subsequent launches of the Pentium dual-core processor-clock frequency should increase to 2. 0GHz above, the performance should be more performance advantages. .
Intel Core2 Duo(Penryn) T4200(2。.0G)。.
As this is just tell us about the simple performance of several processors, so I only use the account the operational ability of the processor's wPrime (a multi-threaded, multi-core processors similar to the super pi software), and reflects the ability of multimedia rendering The CINEBANCH R10 tested two software, and test machine is not the same as a product, it results only reflect the approximate performance of product positioning, are not directly comparable. .
The following screenshot you can see, the V1 wPrime. .54 temporarily unable to properly identify the Intel Core2 Duo (Penryn) T4200 (2. .0G) processor, but the test still runs. Dual-core at the same time as the operation 32M test 45. .000s (time performance).
Intel Core2 Duo (Penryn) T4200 (2. .0 G). .
While CINEBANCH R10 tests, multi-core and the test results to 3872 (the higher the score the higher performance), but with the same clock speed of T3200 processor is also only about 3500, and frequency higher T3400 (2. .16GHz) score was only around the 3700.
Intel Core2 Duo (Penryn) T4200 (2. .0 G). .
You can see that a new update of 45-nanometer core, this Intel Core2 Duo (Penryn) T4200 (2. .0G) performance has been pretty obvious improvement.
In the wPrime test, we see that the software is still not able to correctly identify the processor type, and Intel Core2 Duo (Penryn) T6400 (2. .0 G) of the score of 43. .953 S, the same frequency than before the T4200 to be a little faster, this should be the difference in the secondary cache performance improvement. .
While CINEBANCH R10 stability and compatibility are better, more notebook product properly, by the following screenshot you can see that the Intel Core2 Duo (Penryn) T6400 (2. .0G) has a score of 4054, frequency higher Intel Core2 Duo (Penryn) T6600 (2. .2G) score is compared to 4370, mainstream T4000 series processors have greatly.
Intel Core2 Duo (Penryn) T6400 (2. .0 G). .
As the successor T5800 T6400 in core architecture and manufacturing large changes in, and support for SSE4. .1 instruction set, but multimedia core frequency, 512 KB L2 cache and FSB remain the same, so the overall performance will not be too obvious.
Below, we first pass the T6400 CPU-Z to see the detailed parameters:. .
45nm Core 2 Duo T6400 processor specifications.
And the current high-end positioning in the P7350 compared, T6400 core frequency the same, but the secondary cache and a slightly streamlined front-side bus, and power consumption is slightly higher TDP. Based on our testing experience, sort of processor performance in decreasing order is: kernel Architecture "core frequency> secondary cache> front-side bus. .
According to Intel's planning, T6400 processor this level will not be included in the Centrino 2 family, must be a T9000 series p or series of it — in fact, in the future, the Centrino 2 family will P series processor, because their power consumption of only 25W, calorific value smaller, longer life.

In PCMark05 tests, this books won 4366, where the processor is a subproject of achievements over 5000, which means that the performance for most T6400 users enough!.
T6400 is a Core 2 Duo T5800 upgraded version, the frequency did not change, still 2. .0 GHz, upgrade to 45-nanometer manufacturing process, the core upgrade to Penryn core, upgraded to SSE4. .1 Multimedia instruction set. .
T6600 can be viewed as other high-frequency version T6400 are the same, just the clock speed to 2. .2GHz.
Intel Core 2 Duo T6500 processor, T6400 and T6600 in between, 2. .1 GHz frequency / 2MB secondary cache / 800MHz front side bus. .
Therefore, the only difference in frequency, other are negligible. T6500 processor clock speed than T6600 reduces 0. .1Ghz, CPU type Intel Core 2 Duo for most consumers, the laptop model is the number of letters and numbers. But in fact, all major brands of notebook manufacturers have their own model naming rules. If you are able to understand these rules, you can use the notebook model to product information.
"Ten brand naming Detailed models of notebook computers." .
Here's to introduce Lenovo, ThinkPad, Shenzhou, Hewlett-Packard, Dell, ASUS, Acer, Toshiba, Sony and Samsung and other brands of laptop models naming rules.
● naming Lenovo notebook models. .
At present, the main of the Lenovo notebook can be divided into three series: Lenovo 3000 series (at a low price as a selling point, the main consumer markets), Lenovo IdeaPad series (for the excellent audio-visual entertainment functions as a selling point, the main consumer markets) and Lenovo zhaoyang series (with excellent body design as a selling point, the main business office market). The following is an example for everyone to introduce Lenovo notebook models naming rules.
Lenovo 3000 G530. .
Lenovo 3000 series include: G530 (premium entertainment), the G430 (premium classic) and G230 (excellent portable). Among them, and also into G530M G530 G530A; G430 also divided into G430L, G430M and G430A; there is only one kind of G230G G230.
One, "G" that this machine is low-priced value products; "G after the first number" can be seen that this machine's screen size (5 on behalf of 15 inches, 4 on behalf of 14 inches, 2 for 12 inches); "G behind the second and the third digit" can be seen several generations of this machine is the first product (the larger the number the more it means this product is new); "last letter" can be seen with what type of product to the processor and graphics card (L Celeron processor on behalf of, M on behalf of the Pentium processor, A is equipped with a separate graphics card on behalf of, G representatives were not equipped with discrete graphics).。.
Example 1: Lenovo 3000 G530M. One, "G" that this product is a low-cost value products; "5" indicates this product is 15-inch screen design; "30" means that all these two figures it is no less than 30 new products, The two figures of all the products higher than 30 than it is new; "M" that this product is equipped with a Pentium processor, but not equipped with discrete graphics. .
Example 2: Lenovo 3000 G430A. Among them, the "G" indicates that this product is priced premium products; the "4" indicates that this product adopts 14 inch screen design; the "30" means that all of these two numbers is less than 30 products are not new, all two-digit number is higher than 30 products are better than it; "A" indicates that this product is equipped with a video card, but do not know with what type of processor.
Lenovo 3000 G430. .
In General, we will G530M, G530A, G430L, G430M, G230G G430A and called the master model. In the main model, followed by a small horizontal line, the line followed by a series of letters, we will which group called subclasses. Subclasses of the first letter as you can see the processor type (P is PXXXX series processors, T is TXXX series processor); the second and the third letter is processor model first digit abbreviation (TH is 3, 4, FI FO is 5, 6, SI SE is 7, EI is 8).
For example: Lenovo G530A-PSE. One, "P" that this product is equipped with a PXXXX series processor (that is, it absolutely does not belong to the Celeron and the Pentium series, can only belong to Core Series), "SE" is the English word "Seven" (Arabic numerals 7 ) acronym, that this product is P7XXX series processors. .
Lenovo 3000 G230.
In addition, the Lenovo 3000 series notebooks there is a special case - the model followed by a parentheses, brackets write the "L" letter. For example: Lenovo 3000 G530A-TTH once a product with T3200 processor, and later upgrade to the T3400 processor. In this way, the market appeared in two configurations Lenovo 3000 G530A-TTH. In order to make a difference, Lenovo configuration before upgrading the old version of the model followed by the a "(L)". In other words, all models with "(L)" products, all belong to the old configuration before the upgrade version. .
Examples: Lenovo 3000 G530A-TTH (L). . .
Finally, we can conclude that Lenovo 3000 G530A-TTH (L) is a 15-inch screen design, equipped with T3XXX series Pentium dual core laptops and stand-alone video card. Furthermore, the Association has the product been upgraded, this product is not the old version before you upgrade, and configuration is relatively low, so the price should be cheaper.
Above, is the Lenovo 3000 notebook models naming rules. Lenovo IdeaPad series of notebooks and Lenovo Zhaoyang series models with the same naming rules, I do not introduced one by one. .
● ThinkPad notebook models naming rules.
ThinkPad notebook computer according to the product's market position can be divided into: ThinkPad R series of cost-effective class of models, ThinkPad SL series of all-class growth models, ThinkPad X Series models ultimate lightweight class (including Tablet PC) and the ThinkPad T series the perfect balance of performance and portability class models. .
ThinkPad notebook series model differences at a glance.
ThinkPad notebook models in the series of core technology, display and graphics, security and protection, multimedia capabilities, built-in solutions and tools, connectivity, etc. are different. We can query the table above. .
ThinkPad R400 。.
. .
ThinkPad SL400 。.
ThinkPad notebook computers also have a vice models, mainly used to identify shipments of this product place. Among them, the first four numbers are model code (different code combinations for different body design, such as: material, weight, interface, etc.); behind the two figures is the configuration code (different code combinations for different configuration combinations) ; last letter is the area code (C behalf of the Chinese mainland, H represent Hong Kong, V on behalf of China Taiwan, A representative of Singapore, U represent the United States, J on behalf of Japan). In other words, the Chinese mainland market, "H, V, A, U, J" and other products that are all the letters at the end of parallel imports. .
ThinkPad X300 。.
Example: ThinkPad X200t-74697BC. One, "ThinkPad" is the brand name; "X" that this product is the ultimate lightweight class type; "2" indicates that this product uses a 12 inch screen design; "00" indicates that this product is the first generation of the series; "t" that this product is a flat series of models (for details, refer to the following related articles); "behind the 7469 horizontal" models of this product code; "behind dash 7B" is this product configuration code; "the last letter C" sites that ship this product in mainland China. .
Finally, we can conclude that ThinkPad X200t-74697BC is a 12-inch flat-screen design of the laptop. It is the first generation of products, the shipment locations in the Chinese mainland, Hong Kong. In other words, for China market, this is a mainstream.
ThinkPad X200. .
In addition, the ThinkPad notebook is also Deputy of the designation of a special case. If the associate models is the last three letters of "CTO", indicates that this product is a user through tailored Configure-To-Order system system.
Recently, ThinkPad notebooks to digital at the end there a number of models, such as: ThinkPad X200-7454HT1. These products do not use the model mentioned above naming rules, because they are big clients. ThinkPad X200-7454HT1 of the original model name should be the ThinkPad X200-7454CTO, then there will be a text of the original models of the following comments - CTO ID is "HT1". .
ThinkPad T400 。.
Above, that is, models of ThinkPad notebook product naming. Model code and configuration code, we would not pondering, and basically no one will take the time to write it. Most useful to us is through the model can be seen that the screen size and shipping location. Especially the shipping location, we can determine the last letter of this product is licensed, or parallel imports. .
● Hasee notebooks models naming rules.
Shenzhou notebook has 3 major products: Days Yun series emphasizes "low price", in the configuration on the basis of sufficient and greatly compressed product prices; "carrier" series emphasizes "high performance", the price is reasonable, based on the pole land to enhance product configuration; "elegant (quotations parameter image evaluation)" series of emphasis on "comfort" in the configuration and price are relatively good basis to provide a more attractive appearance and a more user-friendly design. .
Shenzhou F7300 day.
. .
Special Note: Shenzhou notebook model number of the last letter is representative of the optical drive, and not on behalf of the popular online video card. Now, the dev's new notebooks have abandoned this type naming rules, began as an end.
Shenzhou carrier L840T. .
Examples: Shenzhou L840T carrier. Among them, the "Shenzhou" is the brand name; "carrier" means the product is a high-performance series models; "L" indicates that this product design with 15-inch screen; "840" indicates that this product is equipped with P8400 processor; "the last letter T" indicates that this product is equipped with a video card.
Finally, we can conclude: Shenzhou carrier L840T is a 15-inch screen design, with a P8400 processor and discrete graphics notebooks. .
In addition, there is a special case needs attention. We all know, hasee notebooks every time there will be a free upgrade for a configuration. For the purchase of Shenzhou notebook consumers, this is definitely a good thing. However, this behavior will not have affected the product naming rules. For example: Shenzhou F1500 day. Originally this product is equipped with a processor, then T1500 after two upgrade this product is equipped with a T2390 processor, but it's model number or the "Shenzhou F1500" day. In this way, you cannot apply the above model naming rules.
Shenzhou elegant HP940. .
Shenzhou elegance series portable models naming convention confusing is currently in the "status variables".
● HP notebook models naming rules. .
At present, the main HP notebook can be divided into three series of HP's Compaq Presario-CQ series (at a low price as a selling point, the main consumer markets), HP Pavilion dv series (for the excellent audio-visual entertainment functions as a selling point, the main personal consumer market) and the HP Compaq series (outstanding business functionality as a selling point, the main business office market). Here's to discuss HP notebook models naming rules.
HP Compaq Presario CQ45. .
HP Compaq Presario series main products: HP Compaq Presario CQ40 series and HP Compaq Presario CQ45 series. We directly with a specific product model for an explanation.
. .
Finally, we can conclude that it is Hewlett Packard Compaq Presario CQ40-112AU a 14 inch screen design, equipped with an AMD processor and integrated video low-end personal consumer laptop.
HP Pavilion dv4. .
HP Pavilion series main products: HP Pavilion dv5 series, HP Pavilion dv4 series and HP Pavilion dv3 series. We directly with a specific product model for an explanation.
. .
Finally, we can conclude that HP Pavilion dv41214TX is a 14-inch screen design, equipped with an Intel processor and a discrete graphics of audio-visual entertainment class notebooks..
HP Compaq 6531s. .
HP Compaq series main products: HP Compaq and HP Compaq 6535s 6531s. . .
Examples: HP Compaq 6531s. "HP" is the brand name "Compaq" said this product belongs to the business series models; the "6" indicates that this machine is a desktop alternative products; "5" indicates that this machine is part of the business products, "3" indicates that this machine is the 3rd generation product series; "1" indicates that this machine is equipped with Intel processors; the "s" indicates that the configuration of this machine belongs to the standard.
Finally, we can conclude: HP Compaq 6531s is equipped with an Intel processor, a business class laptop. Although it is a business class notebook, but its configuration with the most personal consumer notebook the same, we can use it to replace the desktop PC. .
● Dell laptop model naming rules.
Dell notebook computers can be divided into: household and commercial products. Among them, the Inspiron line of household products, including models of economics, Studio series of audio and video entertainment Games models and XPS series models; Vostro series of commercial products include models economics, Latitude series of safe and reliable class of models, and Precision series of workstation class machines type. .
Dell Vostro1310.
Dell is part of most home and business notebook laptop model naming rules are relatively simple, basically by "brand name", "family name", "screen size", "the first several generations of products" and "configuration code" component. .
Examples: Dell Vostro1310 (S520194CN). Among them, the "Dell" is the brand name "Vostro" said this product belongs to the economic business models; "13" indicates that this product is a 13-inch screen design; "10" represents all the digits below 10 products are not new, all two-digit number is higher than 10 products are better than it; and finally, a set of parentheses in letters and numbers is the product of the configuration code, as long as the landing Dell official website you can find the appropriate configuration.
Finally, we can conclude: Dell Vostro1310 (S520194CN) is a 13-inch screen designed for the economy class business notebook computers. .
However, most business notebook Dell naming conventions also confusing and is now in the "status variables".
● Asus notebook models naming rules. .
ASUS notebook models naming rules: ASUS notebook parts in accordance with the model letters and numbers that correspond to product information, can be divided into five segments. Please look at the picture below:.
Asus notebook models break down. .
The number 1 position of letters and numbers is the product's serial number (for details please see the following "ASUS notebook serial number list" table).
Asus notebook serial number list. .
2, the position of the letter as you can see this product in the screen size (for details please see the following "ASUS No.2 position letter details" table).
Detailed location of the 2nd letter of ASUS. .
3 you can see the position of this product is equipped with what processor (for example: "81" is 84 T8100 processor, "P8400 processor" is).

It comes with Intel Core 2 Duo T6400 processor, 1GB memory, 160GB hard drive, DVD burner, graphics card (video card, but do not know the model) and the 5100AGN wireless card. .
In General, we can understand the Acer notebook model to many product information. However, the premise is that you can learn its naming rules.
● naming Toshiba notebook models. .
At present, the main of Toshiba notebook can be divided into four series: Satellite series (at a low price as a selling point, super price products), Portege series (slim body as a selling point, ultramobile class product), Qosmio series (with powerful audio-visual entertainment features as a selling point, duomeitilei products) and Tecra series (in a safe and reliable body design as a selling point, business product).
Toshiba Satellite M333. .
Toshiba laptop model naming rules: the series, the first letter is a model code (different letters that represent different body design, such as material, weight, interfaces, etc.); the first digit you can see that this machine is the first generations (the higher the number, it indicates that this product is new); the numbers following the is this product configuration code that used to come with the same series of other models do..
● Sony laptop model naming rules. .
At present, the main of Sony notebook can be divided into ten series: Z2 series (13 inch-business), the TT series (11-inch-business), TZ series (11-inch-business), the CS-series (14-inch personal consumer), CR series (14-inch personal consumer), SR (13-inch personal consumption + business-oriented), AW series (18-inch audio-visual entertainment), FW series (16-inch audio-visual entertainment), js (20-inch home audio-visual entertainment) and NS Series (economical audio-visual entertainment).
List of Sony notebooks. .
Sony laptop model naming rules: the serial number on the back of the first digit you can see that this machine is the first generations (the higher the number, it indicates that this product is new), the second digit is the product configuration code that used to come with the same series of distinguished from other models; the last letter representing the product's enclosure color (serial number, a letter on behalf of the colors are different).
For example: Sony VGN-CS19 / P. Among them, the "Sony" is a brand name; "VGN-CS" is the serial number, that this product is 14 inch personal consumer notebooks; "1" indicates this product is the first generation; "9" is the configuration code used to with the other models do the same distinction between the series, there is no special significance; "P" on behalf of this product is pink case. .
?Samsung notebook models naming rules.
Currently, Samsung notebook market can be divided into four series: R series (mainstream all-around), X series (high fashion), Q series (light and portable) and the P series (Business Classics). .
Samsung X360-AA03.
Samsung notebook models naming rules: the first letter is the model series number, you can see the market positioning of this product; serial number after the first number can be seen that this product is the screen size (2 for 12-inch, 3 for 13 inch, 4 on behalf of 14-inch, 5 on behalf of 15 inches); second and third digits can be seen that this machine is the first generations of products (the larger the number the more it means this product is new); letter after dash and the figure is the configuration of this product code, used with other models to do the same distinction between the series. .
Examples: Samsung X360-AA03. "Samsung" is the brand name; the "X" is a series of numbers that represent this machine belongs to the fashion of high-end products; the "3" this product is equipped with 13-inch screen; the "60" means that all of these two numbers is less than 60 products are not new, all two-digit number is higher than 60 product than it is behind the new; horizontal line "AA03" is the product configuration code that used to come with the same series of other models do. The pros and cons of the video card is a high-end gaming can be fascinating. . These mobile graphics products, this will briefly summarize the information, summary information will be synchronized with the product to facilitate the concerns of the faithful can move the card at any time to view, this introduces ATI's products. .
ATI Radeon series and x series will no doubt have been widely known in this frenzy. The former ATI Radeon (commonly known as the "Radium") was born in April 2000, ATI AGP interface age origin. It should be said, that is, from "Radeon" series, ATI notebook chip began and brand machine parallel along the route. Mobility Radeon Mobility 7500 is undoubtedly the most long-lived Radeon series, it is introducing ATI with 0.15 μ m manufacturing process for mobile display chip.
Until now, we can see in some of the classic models of its shadow, such as the IBM T42. Subsequent Mobility Radeon 9000 is based on the desktop Radeon 9000 mobile chip in performance, than the former to win twice on. Mobility Radeon 9200 Mobility Radeon 9000 is an upgraded version of the Mobility Radeon series even created a few first, but the shortcomings do not support DX9, or did not make it to retain the market's enthusiasm for living.。.
So far, the market there are still some models support the TV reception in the use of this card. Radeon series of late works - Mobility Radeon 9700 and Mobility Radeon 9800 is basically born 04 years ago, it should be said that the radium from the recent series of products now, but had the price is too expensive, so at that time the market has not seen related products, even in the present, the relevant models are still rarely seen. .
X series is the AGP ATI from changing to PCI-E "new era" flag, ATI in June 2004 was first published by PCI-E interface graphics — Mobility Radeon X600, subsequent Mobility Radeon Radeon X800 X300, Mobility and Mobility Radeon ATI mobile X700 is displayed in the field of the third period is an important sign of approaching.
Since then, the series used "2300" as the nexus, began to "HD" prefix started "high-end audio and video entertainment," the name! Currently, the latest 3000 series ATI Mobility Radeon HD 3450/3650 of the DirectX version has been upgraded to DirectX10. .1 Than NVIDIA's rival version with even higher quality products, advantages swept the industry, a time of hard to find opponents. .
ATI Mobility FireGL series ATI's Mobile Edition of workstation-class graphics products, mainly in response to specific customer groups, such as graphical workers, etc. At present, the series has been published six models to ATI Mobility FireGL V5200 version maximum correlation models on the market, can also receive a price quote.
Overall speaking, the present three series ATI mobile graphics products, to "ATI Mobility Radeon HD" as the absolute mainstream, high-end audio and video entertainment products for the models, however, thin models are less commonly used nowadays. Constant concern of the Friends of the graphics market, you can refer to the following we summarize the ATI mobile graphics data. .
Pentium dual-core and core 2 What's the difference?.
9500M GS and HD 4570 what strength the weak what? . .
Games and graphics, CPU and video card should be how to mix?.
If you have not figure out these questions, then when you go to the city to buy a notebook computer, may be necessary to be careful, because you hardly get from most businesses accurate answer - they either did not clear his or is deliberate deception. In either case, the final loss of all consumers. In order to avoid the occurrence of these situations, we need to move the processor and graphics card specifications are subject to understand. .
· Mainstream CPU parameters and performance.
Currently on the market 80% of notebooks use Intel processors, they can be from low to high is divided into four series: Celeron Dual Core, Pentium Dual Core, Core 2 Duo (T series), Core 2 Duo (P series). Because they use the same core architecture: Intel Core microarchitecture, so its performance depends mainly determined by the core frequency, followed by the secondary cache and front side bus. .
In fact, today's processor performance by leaps and bounds, and normal user demand and three to five years ago without much change — Internet downloading, watch movies and listen to the music, play simple games. Thus our test experience Celeron T1600 core performance basic enough, but the 45-nanometer Intel Pentium dual core T4200 fully meet the needs of the vast majority of users. In other words, t-series processor, the Intel Core 2 Duo T6400 above model is performance of excess, spend the few thousand dollars is not necessary.
However, there is one exception, that is, P series processors. P series of the parameters and 45 nm are almost the same T-series, just power from 35 watts TDP to 25 watts, so no loss in performance under the premise of heat is smaller, longer battery life. So as long as your budget adequate, we recommend that you try to select the P series processors, such as the most cost-effective Core 2 P7350 and P7450. .
Mainstream mobile processor parameters and performance comparisons.
In addition, we noted that some consumers are small and cheap access to the Internet interest in the show, here we want to remind you: the Internet is only suitable for notebook and desktop supplementary tool, can run only the most basic procedures, such as the Internet, play PPT, watching movies, and so simple, in the run Office2007, PhotoShop and other large programs will become very slow - in the table you can see, Atom N270 performance was less than half of the dual-core Celeron . Also note that Internet screen and keyboard size is too small, it will seriously affect the operation of the user experience. .
On the other hand, if the Atom is by far the most inexpensive Intel processors, the most expensive is the "small package + ultra low voltage" both unlocks the secrets of SU series processors, such as the core 2 Duo SU9400, etc. They are mostly applied to those expensive super thin and light notebook, ThinkPad X301, Toshiba R600, etc. Their greatest advantage is the extremely power efficient, while performance is also passable (and Celeron dual-core almost), but is too expensive.
* Mainstream graphics parameters and performance comparison. .
And processors, notebook graphics model is complex, the largest graphics chip giant (Intel, NVIDIA, AMD) has been formed three kingdoms of market structure. Which Intel with Centrino platform bundling, and low-power, GMA series of integrated video takes up nearly 40% market share, while the other 60% are mainly by NVIDIA and AMD discrete graphics are divided up.
If you frequently use the notebook outdoors, on a higher battery life requirements, then the Intel Centrino 2 platform, GMA X4500 is the best choice. As an integrated graphics, its power consumption is much lower than the graphics card, although it is difficult to run, "Need for Speed 12" of such large-scale 3D game, but under the low-quality play "World of Warcraft" or can . If you are not only high performance but also lower power consumption, you can consider supporting the switching of the "dual-graphics" notebook. .
Taking into account the energy-saving power on your notebook, NVIDIA and AMD has launched its own integrated graphics: 9400M and HD 3200. They even though market share as Intel's GMA X4500, but actual performance is better, especially the 9400M performance and HD 3470 such discrete graphics comparable to, unfortunately the courage to Intel "too few manufacturers.
The parameters of the mainstream and performance mobile graphics comparison. .
In discrete graphics choice, here we show you a small Tip: focus on "graphics memory bandwidth," this parameter — 64 belonging to low-end graphics, 128bit belonging to mid-range graphics card, 256bit belonging to high-end video cards. Secondly, stream processors, graphics core frequency and type of the parameter is also very important. While many businesses used to publicity graphics memory capacity, in fact, this parameter is not a very important, as long as the ratio of the video memory bandwidth is usually slightly higher, like 512MB/64bit this specification is a gimmick, performance is far better than 256MB/128bit mix.
Taking into account factors such as heat and power, for most 6000 yuan alone significantly below the low end of the still 64bit graphics-based, for the vast majority of ordinary consumers, such as the 9300M GS and HD 3470, they are suitable for playing "World of Warcraft World "online game or two or three years ago, these stand-alone game. If you are a gaming enthusiast, you might consider such a 9600M GT and HD3650 128bit memory interface of the end graphics card. .
It should be noted that the current AMD and NVIDIA are preparing the next renewal, AMD has an action, such as the new HD 4570 already appears in the market. As an upgraded version of the HD 3470, stream processors, doubling the number of undoubtedly become the most powerful supercomputer ' where the video card, and the old paragraph 128bit graphics. It seems this AMD scramble is very strong confidence in the market, the next-generation graphics card NVIDIA G100M series is facing enormous challenges.
* Purchase suggestions and recommended models. .
Front and say that perhaps some beginner or confused: "which notebook is most suitable for me?" don't worry, we have for different types of consumers, namely recommended several solid workmanship and price books.
1. . Equalizer versatile. .

* Summary:. .
Read this article, do you feel something? finally, we would also like to remind you that you have selected the appropriate online models, can only be successful by half. The next question is: what kind of purchase channels select? if you go to the mall to buy, how to avoid pitfalls shortchange? inspection machines and invoiced should also pay attention to what issues? intel T4200 processor T3200 alternatives.
. .
Intel Core2 Duo figure (Penryn) T4200 (2. .0G) is recognized as P7350.
intel T6400 T5800 processor as an alternative product. .
Intel Pentium dual core T4200 processor is the latest Intel Core 2 Duo P8400 with Penryn architecture, improved with T3200 than front side bus and SSE4 instruction set and .1.45nm new schema. T5800 with level 2 cache than it shrinks to 1M, SSE4. .1 instruction set (instruction set to be determined) and 45nm architecture. 3 gigahertz are U 2. .0G.
On the processor performance in decreasing order were: kernel Architecture "core frequency> secondary cache> front-side bus. .
T5800 with Merom architecture, 65 nm, 45 nm is not T5800 and T4200 think! is the only advantage is to cache, but this? schema is too old! older Pentium m single core processors (not the current Pentium dual-core) 3M L2 cache, and the core 2 than now?.
I want to clarify, intel Pentium dual-core t4200 processor definitely better than the T5800! As a new core, intel Pentium dual-core t4200 T5800 processor performance even for no obvious advantage, but at least never worse than the T5800! Do not be "Pentium" and "Core" name to the confusion, and it was just a brand's trademark. .
Core 2, Pentium dual-core and Celeron dual-core is a series of three Intel are high-end and mid-range and low-end. Similar to the previous Pentium 4 and Celeron D..
Pentium dual-core is not a transitional product, but get out of than the Core 2 Duo is also late. Purpose of the AMD turion processor and cheap competition. .
Pentium dual-core and multi-core is exactly the same core architecture, the difference is just the L2 cache and FSB. Pentium dual-core T20XX series uses core 1Yonah core. Pentium dual-core T2310 to T3400 with core 2 Duo T5 and T7 series of Merom architecture. Intel Pentium dual core t4200 processor is the latest Intel Core 2 Duo P8400 with Penryn architecture.
intel Pentium dual-core t4200 processor architecture whole new generation than the T5800! Although less secondary cache 1M, but intel Pentium dual-core t4200 processor is the latest 45-nanometer Penryn technology, architecture, than using 65-nanometer technology, the MEROM T5800 10 watts per hour power structure to support the SSE4 instruction set, but also than just support the SSE3 instruction set t5800 owned strong performance. DDR3 memory support for updates. Comprehensive view, T4200 than the T5800 much good! And T2390 processors on Core 1 on behalf of the T2400 than the more the same. .
Don't be core, Pentium, Celeron, name a confused, don't use JS name to mislead consumers.
T4200 and T5800 can be performance, as can be equated. But the structure, power consumption, SSE4. .1 Powerful multimedia video instruction sets, T4200 processor completely dominant. .
Specific intel Pentium dual core t4200 processor parameter can refer to this article, the mainstream Laptop CPU model series, as can be seen by comparing our t4200 basic = 5800.
. .
T4200 through its clock speed, new, new technologies, as a cheap notebook provides unprecedented leap. The currently used T4200 cost-effective notebook is the Shenzhou 7-up carrier L420T, V86 and new blue A4540 (907). The notebook is within the $ 400 price independent video, especially for the dev notebook 8-cell lithium battery wiring. The new blue 9200M GS video card for use can be said for the position of your notebook perfectly. New release of seven-up V86 is using a video card and 9300MGS 250G SATA hard drive, the same will be priced at $ 3880.
As for the T5800 and T5870, are equal. U maybe has a little difference, with a superior's words: T5800 is to be modified INTEL pins can be installed in GM45, PM45 chipset, the T5870. Performance conclusions, T4200 = T5800 = T5870> T3200. .
