1. The operation result of the buffer display core
is simply when processing complex images, such as complex
3D scenes with a large number of polygons
, high
bit rate
high-definition video with wide range dynamic changes. If the video memory is insufficient, it will be obviously not smooth.

2. Video memory is used to cache data. High resolution, high quality maps and special effects will increase the amount of video memory<
hd7850 was launched in 2GB version, and later it was released in 1GB version. You can see the usage of video memory with gpu-z - high end video cards such as R9 290x mainly focus on 4K resolution and have 4GB video memory.

3. It's not that the larger the video memory, the better. It depends on whether the bit rate is 128bit or 256bit. At present, the mainstream configuration is 128bit. If it's 64bit, it's rubbish. It also depends on what kind of graphics card you buy. At present, 7600gt 256MB is enough for the middle end graphics card, 512MB for the high-end 7900 and 128MB for the low-end 7300gs, because if the display chip can't keep up, no matter how large the memory is, it won't help
generally speaking, the matching of video memory is reasonable for mainstream procts on the market. There is no need to deliberately pursue large video memory. As I said just now, the cost may be increased, but the performance may not be greatly improved. If you pursue high performance, it's better to buy high-end procts with small video memory than high-end procts with large video memory in the middle end.

4. Memory is used to store the running programs. With large capacity, the computer can run more programs at the same time. The intuitive performance is that the computer is faster, opening more programs may not be stuck.
video memory is used to store the temporary data of the video card. The higher the complexity of the game, the higher the special effects, and the larger the video memory needed, but the memory capacity needs to be the same as that of the video card

5. Large display memory, mainly in high resolution, the formation of multi screen and other circumstances
if you don't have these applications, don't buy large video memory models to avoid meaningless waste.

6. It needs to be determined according to the specific situation:
when the display memory size is less than 1GB, it has a great impact on the performance of the graphics card. For example, the performance of the graphics card with 1GB of display memory and the graphics card with 512MB of display memory is very different. The main reason is that:
when the display size is more than 19 inches, the display memory must be more than 1GB to achieve the complete display effect, and the larger the screen is, The higher the demand for video memory
at present, the minimum video memory requirement of some games is 512MB. If the video memory is 512MB, the game effect is not very good
if the video memory is more than 1GB, the performance of the video card will not be greatly affected. Of course, for large games or large display screens, the impact is very great
for today's mainstream graphics cards, the video memory is more than 1GB, and for high-end graphics cards, the video memory is 4GB or even 8GB, so you don't have to consider the factor of video memory too much.

7. There are two main aspects of the performance of video memory capacity
first, the size of the display has certain requirements on the capacity of the display memory. If the display size is 19 inches or more, it is best to choose a 1g video memory capacity graphics card. If the display size is less than 19 inches, 512MB is enough. If the display size exceeds 27 inches, then 1g video memory capacity is not enough, 1.5g or even 2G video memory capacity is needed
the second is the requirement of video memory capacity. Nowadays, many games require that the video memory capacity of the video card should be at least 512MB. That is to say, the video memory capacity of 512MB is only a minimum requirement for games, and this minimum requirement is often not satisfactory. For example, GTA4 requires a minimum of 512MB of video memory. But if you really take a 512MB video memory card to run the game, you will find that many special effects of the game can't be opened, because the video memory capacity is too small. If you open other special effects, the video memory capacity is not enough. So the picture of the game will be terrible
therefore, it is necessary to buy a graphics card with 1G memory capacity now, so you don't need to consider 512MB. Even if the performance of a graphics card is low, you should choose 1g. But is it necessary for a graphics card with 2G video memory? In my opinion, at least for the moment, there is not much need, unless your graphics card is a high-end graphics card (the price is more than 2000 yuan) or your display size is relatively large
as for the version of DirectX, naturally, the higher the version is, the more colorful and lifelike the game screen is
but this is limited by two conditions. The first condition is which version the game itself supports. If this game only supports dx10.0, even if dx11.0 is installed in the computer, it can't present a more realistic picture. Second, the number of DX versions supported by the graphics hardware. For example, the 9800gt graphics card only supports dx10.0, but does not support dx11.0. Therefore, although its performance is higher than that of the GT 440 graphics card, the special effects of dx11.0 can not be reflected. As a result, the game images presented by GT 440 are more beautiful than those of 9800gt.

8. In fact, video memory and memory mole are almost the same. They are both used as virtual memory. The size of video memory affects the size of each processing effect of the video card. Maybe what I mean is not slow and clear, which is basically what I mean
the effect of the game is too good, it's best not to turn on anti aliasing, so the burden of the graphics card is quite large, and the burden of water reflection and anti aliasing on the graphics card is quite large! Large video memory requires large bit width of the video card to process more data

9.
The functions of video memory and memory are similar. They are containers for storing data temporarily. GPU can't work without video memory
at present, there are three specifications GDDR3, gddr5 and DDR3. Gddr5 is generally used in high performance graphics card; GDDR3 is used in entry-level graphics card; DDR3 is the integrated graphics card directly calls the system memory as the video memory. Video memory directly affects the bandwidth. Under the same conditions, the speed of gddr5 is twice that of GDDR3. Bandwidth reflects the speed of data exchange between GPU and video memory, and indirectly reflects the performance of video card
2GB video memory is enough for any game under 1080p. If it is expanded to 1600p, the video memory will be increased to 3gb. Larger video memory, such as 6GB and 8GB, is mainly used in the case of single card with multiple screens, as shown in the figure below:
the price of professional graphics card can reach 40000 yuan / piece
summary:
choose gddr5 video memory with high frequency as far as possible; 2GB gddr5 at 1080p; 3gb gddr5 under 1600p; The larger the capacity of single card, the better; The larger the capacity of professional graphics card, the better; But in the final analysis, it depends on the performance of GPU itself
10. To be simple, it is to store temporary files like memory. The difference is that memory serves CPU and video memory serves video card.
the size of video memory has a certain influence on the performance of video card, but it is not the main factor
