Does GT540m have 2G VRAM??? Specifications of GT540m

First of all, correct your concept of what is video memory According to Du Niang's explanation: video memory, also known as frame buffer, is used to store the rendering data that has been processed or is about to be extracted by the graphics card chip. It is to store the data from the graphics card chip, but the problem is how much data is processed by your graphics card Here you should understand The key is how much data you process For example, your water is only ll You use a large cup or only 1L of water In my personal opinion, under the resolution of the notebook (the resolution is related to the processing of the graphics card chip), 512MB video memory is enough (of course, 1G is better, and it is more basically wasteful) So video memory is a gimmick, so is the video memory useful When playing games, if you have a large resolution screen connected to it, you will be able to use it...

As for the detailed parameters of the GT540M Presumptuous question Do you understand I don't understand Honestly, but for this graphics card Mid-range graphics card The mainstream of the game popularization of this mobile graphics card But it can be basically asserted that 2012 is definitely not his world The machine generally equipped with the graphics card The processor will not be too bad So, the mainstream online games are all in one go, and the big games can be opened a lot lower Graphics card killer games like Battlefield 3 I really don't know if I can open low You can take a look at the evaluation.

Yes, there is, but for mid-range graphics cards, there is basically no difference between 1G and 2G of video memory. Only high-end graphics cards have noticeable memory performance. For example, Lenovo's V 470 uses a 2G GT 540 graphics card.

The detailed parameters are all you need. It's not clear here.

The GT540M version does not have 2G VRAM! You want to detail the parameters and leave an email

GT550M is a notebook graphics card, and M is a notebook graphics card suffix, also called mobile version - mobile.

The GT550 does not have this graphics card, but the GTX550TI, which is used on desktops.

All notebook and desktop graphics cards, even if the model looks the same, the performance cannot be compared side-by-side.

The performance of desktops is generally stronger than that of notebooks, and some are much stronger.

gt550m：

Bit width: 128bit Stream Processor: 96 Core frequency: 740 Video memory frequency: 1800 or 3600 Video memory type: GDDR3 or 5

gtx550ti：

Bit width: 192bit Stream Processor: 192 Core frequency: 950 Video memory frequency: 4100 Video memory type: GDDR5

And the notebook graphics card GT550M most notebooks are using the GDDR3 video memory type,This has a lot of discounts,With GDDR5 you can watch some special game books,For example, the alien series, etc.。

In addition, video memory does not need to be studied too much. For all civilian notebooks, it is completely sufficient to use 1G, and it is a waste that the performance of the graphics card cannot keep up with the large video memory. For example, video memory is like a parking lot, bit width is like a parking lot gate, and core frequency is like the speed of a registered car.

These require a dynamic balance.

2G for laptop graphics cards is a gimmick on most machines, and it is not much different from 1G video memory.

Most versions of the GT550TI, which is stronger than it, still use 1G, and the GT550M actually sometimes doesn't even use 1G.

If you want to buy a book,GT550M book can be bought,Of course, GT630 640 650M graphics cards are also about to start popularizing.,You can wait and see.。 For graphics cards, the GT550TI can be purchased, and the GT670 680 690 is already on the market.

Both have their advantages and disadvantages.

In terms of performance, 640m is definitely stronger than 650m. 640M as a mid-range graphics card,In fact, it can't fully exert the full performance of 2G video memory,2G video memory is actually a waste for graphics cards like 640M,1G video memory capacity is also enough。

Although the 650M is more powerful, the 512MB video memory is obviously too little from the current point of view, and it would be better if the video memory capacity could reach 1G. And now in some games, 512MB video memory capacity is really not enough (such as a game like "General 2: Total War", 1G video memory capacity can run the game smoothly).

Therefore, if the video memory capacity is only in terms of video memory capacity, it is recommended to use 640M, because although its performance is not as good as 650M, the too little video memory capacity limits the performance of 650M. Although 640M is more wasteful with 2G video memory, waste is better than limitation.

The GT550 is a high-frequency version of the GT550 GT540 that doesn't make much of a difference.

GT550, 2G Of course it's good.

GT445M is a mobile graphics card for notebooks after all, heat dissipation should be considered, and the frequency is very low, not as good as the GT240 and GT430 of desktops, the video memory of desktops is DDR5 above 3600MHz, and notebooks are generally DDR3, up to 1400MHz.

The graphics card of the notebook cannot be compared with the desktop, but compared with the graphics card of the same grade of the notebook, the GT445M is already good in the notebook.

Ironclad is better than GT240, it seems that there is no GTX240, you are mistaken, even it is only GTS, GT445M has a test score of more than 10,000 points in 3DMark06, and the best graphics card for the current notebook is GT555, which is said to be 13000 points.

GT580M for K445? This is similar to the desktop 9600GT, which is about the same as the GT240 GDDR5 version.

The desktop GT430 has only 48 SPs, and its performance is much worse than that of the GT445M.

Not as good as the GT240, worse than the 240. None of them have an X, and a 460 is GTX.

The GT445M is between the desktop GT440 and the low-frequency GTS450.

The problem of GT240M has been mentioned above 2L, and the number of stream processors is too small, of course, it is the bottom.

The rest of GT425M,GT420M,GT335M comparison is actually not difficult,From the core specifications, GT335M and GT425M are almost the same,Both are 96 stream processors + 16 ROPS units,But the core frequency is different,GT335M is 450MHz,GT425M is slightly higher,Up to 560MHz,From the perspective of stream processor frequency,The two are almost the same,GT335M is 1080MHz, The GT425M is 1120MHzTherefore, it can be considered that the core computing power of the GT425M is slightly stronger than that of the GT335M, but the gap is very small.

Let's take a look at the comparison of video memory, both are 1GB 128bit specifications, and the memory frequency is exactly the same, so in the video memory, the two are at the same level.

From the comparison of the test scores of the 3DMark Vantage, the GT335M is more than 11,300 points, while the GT425M is slightly higher at more than 11,700 points, which is very consistent with the gap in specifications, so the test results are definitely fine. In other words, the GT425M is slightly stronger than the GT335M, but the strength is very limited, and it can be regarded as almost the same performance in general games.

The real advantage of the GT425M is that it supports DX11, while the GT335M can only support it, and this is the fundamental difference.

As for the GT420M, it belongs to the low-frequency version of the GT425M, and the performance is slightly worse, which can basically be regarded as the DX11 version of the GT330M, and the performance is also slightly higher than that of the GT330M.

gt425m＞gt335m＞gt420m＞gt240m

The GT240M is the worst because it has the least number of streams at 48.

The remaining 3 are all estimated to be 96 stream processors, which is not easy to compare, but according to the naming convention, 425 should be stronger than 420.

Considering that Fermi's stream processor is not competitive, it may be better than GT335.

Specifically, we have to look at the evaluation comparison, maybe GT425 has improved.

Hello. GT240M, GT420M, GT335M, GT425M4 graphics cards actually have only two graphics cards to compete, that is, GT425M, GT335M To be honest, GT425M has one more support DX11 smooth point than GT335M, because after all, it is a new 4 series graphics card from N card, and the effect of supporting DX11 is bound to be better than GT335M, but the driver may be launched a little slower. And GT335M's performance is actually a little better than GT425M,Fortunately,The landlord can go to see a variety of mainstream game graphics card reviews,DX9 series games GT335M is always ahead of GT425M,DX11 series GT425M is not much ahead of GT335M。

Therefore, it is recommended that the landlord must choose carefully on these two graphics cards, after all, the mainstream stand-alone online games are now developing towards DX11.

Finally, I will give the landlord an evaluation: GT335M GT425M GT420M GT240M (performance from high to low).

The 840m stream processor is 4 times faster than the 540m, and the pixel filling speed of 840m is more than 3 times that of the 540m, and the graphics filling speed is about twice as fast.

Look at the graphics card first look at the chip,Chip840Mgm108Both from the process and power consumption, are crushed540MAfter all, there are several generations of products behind,After reading the chip, look at your bit width and video memory,The main determining factor in the performance of the graphics card is still the core,Video memory and bit width are secondary,Just like you540M with a GDDR5 8G 512bit super video memory is just an old cow pulling a broken car, there is no significant improvement。

Finally, from the running score, to quote a few pictures, this is the running score of 540m+i7, which is the running score of 840m+i5.

After all, the gap between the 3 generations is that the performance of the low-end cards is about more than double, and you will be given a graphics card ladder diagram from the 3DMark official website, you can take a look.

Hello Both of these graphics cards are notebook graphics cards, but the performance can be said to have their own merits. The GF 840M's manufacturing process (28nm) and video memory (2048MB) have completely surpassed the GT 540M. However, the GT 540M has a bit width of 128 bits, which is also DDR3.
