Pure dry goods! What's the use of video memory size?

When it comes to graphics cards, the most important part is probably the video memory, except for the display chip. When we introduced the APU a few days ago, we also specifically mentioned what memory, frequency bandwidth, etc. We believe that the buddies have at least one concept. The more memory the better, the sooner the better. That's right! But is video memory really dry? Why is it so much? So fast? It is estimated that the young buddies are not very clear. Xiao Bian talked about this matter today.

Only one thing, video memory is very simple

Memory is the display card cache. We have mentioned this cache a few days ago. It is a temporary data storage pool that stores temporary data for each hardware and also acts as a buffer for data exchange between memory and various hardware. If there is no cache, all the data of all hardware must be read and written from the memory at the same time, and it is hard-coded to the memory by the hardware's own processing speed, no matter how wide the memory of the “pool” is, and if there is any other data. Running, it will cause serious congestion in the memory and even the entire computer data flow.

Memory speed is much higher than memory

The task of video memory is to store various data required by the video card. We know that the more exquisite, the larger the size of the 3D image, the larger the amount of data. For example, a seamless open large map of chickens needs to be moved in an opening. Memory, so the memory size requirements are particularly high. If it is set to high image quality, the details of grass, trees, houses and vehicles on the map will be more, and the amount of data will certainly be even greater. It needs more memory support.

What if the memory is not enough? The extra data can only be put into the memory, but the performance of the memory is much worse than the memory. Traffic jam will definitely affect the performance of the graphics card. For example, if you are unable to load the map into memory when you are eating chicken, there will be a more or less delay or even a pause when you load the map data from memory. At this time, you must pray that you do not run into the enemy if the card Suddenly fierce battles, Xiaobian can only sing a "cool" to you.

In short, the stronger the display chip, the better the 3D picture can be provided, and the larger the display memory capacity required, the faster the speed. This is why we see the higher end of the display chip, the memory configuration is always better, the configuration of the two is almost always a one-to-one correspondence, such as the low-end GTX1050 graphics card to install 2GB video memory on the line, and the high-end GTX 1070 With 8GB memory, the highest-end graphics card is to use 12GB video memory.

What are the ghosts of 3GB, 5GB, 6GB, GTX1060?

There are always exceptions. For the three GTX1060 video adapters that have been scratching their heads in the near future, how can one use the same display chip with three different video memory configurations? In fact, the reason is very simple, the use of these three GTX1060 graphics card is not the same display chip, the specifications are obviously different, but taking into account the market conditions, did not distinguish between. Take the 3GB version of the GTX1060 graphics card as an example, its chip streamlined a stream processor group compared to the 6GB version, and the number of stream processors was reduced from 1280 to 1152. There is of course a significant gap in performance.

Not only does the GTX 1060 3GB show less memory, the chip is also castrated

Why did Huang Huang play this trick? Because he fancy or the market, 3GB version GTX1060 occupy a lot of players special attention 1300 ~ 1500 yuan price segment, since GTX 1050Ti can not reach this price, do not want to give GTX1060 price cut, it would simply launch a cast version of GTX1060 Well, the cost and price are lower, and it will ensure that players can enjoy chicken games smoothly.

The GTX1060 3GB performs well in general games, but performs very poorly in games that require high memory capacity

GTX1060 5GB is a castration from another perspective. In order to meet the demand of Internet cafes, the cost is reduced by reducing one memory particle, and the performance is slightly higher than the 3GB version, allowing the player to eat chicken under the higher game quality. There is an appellation in the market that can show their performance and positioning very vividly, that is, the memory capacity is integrated into the graphics card model. They are called GTX1063, 1065, and 1066, respectively.

In short, the size of the video memory is very important to the video card. When you buy a video card later, you must not only look at the display chip, but also have to care about the memory capacity.
