5 minutes to read mine clearance test is not a video card!

At the end of the articles that have been pushed in recent days, there have been allegations of mine-sweeping games, and many small friends have all complained about this issue. Xiaobian thought for a long time, jokingly kidding, or just talking about the relationship between graphics and processor.

What is the relationship between CPU and GPU?

For a long time, long ago... Keke, Xiao Bian said that the requirement of the computer in the early years was only to transfer the image to the display device, because it was all characters and there was not much demand. Afterwards, because of the graphical operating system, new requirements were placed on the graphics card, the importance of the graphics card was improved, and the graphics card also had a cache (KB cache) to refresh the image. Since the resolution of the display gradually increased, in order to correspond to high resolution and refresh rate, the graphics card added a stuff called RAMDAC to support it, but in the end it was a supportive device. Still later, because of the emergence of 3D graphics, the requirements for the graphics card have been raised to a new level. The graphics card has since embarked on the fast track of development, and it has become truly an important computer accessory after the CPU.

Why does the CPU have so much higher frequency than the GPU?

In the most direct sense, the CPU has to do floating-point operations and integer operations, and the graphics card is only responsible for floating-point operations. To put it plainly, the CPU needs to carry out various complicated calculations and calculations. The frequency increase is certainly the most effective and direct method and means. Graphics cards are special calculations, focusing on floating-point operations, which require better execution efficiency and parallel processing capabilities, but frequency is the secondary requirement. So, evaluate the CPU, look at the architecture; second look at the frequency; and look at the cache. The GPU summed up, look at the architecture, the second look at the stream processor, three to see the memory, the importance of the frequency but not so important (core frequency, not the memory frequency oh).

There is memory, memory, CPU, GPU but also cache?

In fact, long-term restrictions on the overall performance of the computer has always been storage devices, including memory, hard drives, so there will be higher frequency, standard memory, faster hard drive, and even new devices like Ao Teng. However, due to the gap in frequency and speed between these storage devices and CPUs and GPUs, the gap between CPUs and GPUs is far greater (CPUs and GPUs are far faster than storage devices such as memory and hard disks). Therefore, in order to solve such unequal situations (the CPU must wait for the slow hard disk to read the data and submit it to the memory, the memory is queued to the CPU for processing, and the result is returned step by step). It is necessary to set a value in the CPU and GPU. Buffered memory, it is extremely fast, not even the latest Ao Teng memory such a device can be compared, its size will determine how many data commands can be buffered, largely affect the CPU, GPU computing effect, otherwise CPU and The GPU can only idle and wait for data to be sent.

Of course, one of the reasons that GPUs differ from CPUs is that GPUs actually have only a small amount of lost cache, unlike CPUs that have to be divided into one or two or three levels of cache buffers. This is because the GPU is mainly a computational processor made up of a large number of simd vector units and register sets. It does not have an instruction system because of the large number of arithmetic units. The cache is relatively small and uses direct rendering, so the GPU will constantly access the video memory, which is why the graphics card's GDDR memory performance is much more efficient than memory (more bandwidth and faster). As a side effect, I don't know if the partner noticed it. The core area of ​​the graphics card is surprisingly large and far exceeds the CPU, because the GPU has a huge number of computing units, which leads to a huge transistor scale. This is the difference between the two.

Why dynamic frequency? The graphics card CPU is like this

Whether CPU or GPU, it is now a dynamic frequency operation, that is, after power-on, it runs at a low frequency when it is idle, and the frequency increases significantly when it is fully loaded. Low frequency at low loads means that power consumption is reduced, and heat generation is also greatly reduced. When the load is high, the frequency is greatly increased, and the calculation ability is enhanced to meet the use requirement. In fact, the previous CPU or GPU is worth mentioning, there is no such function, CPU and GPU are a frequency running in the end, wasted when idle, high load can not keep up with the operation requirements. It must be said that the progress of science and technology is still very obvious.

How does the relationship between CPU and GPU look?

Many people said that my computer is too scum, the game can not run, but people have said that my CPU is too poor to feed my own graphics card. Then you know how to most intuitively determine whether your computer is CPU or GPU is not enough? In fact, there is a small trick, Xiao Bian share to everyone:

1. Low-resolution + low-effect settings game, if Caton, said poor CPU performance, this is because at this time the graphics card burden in the lowest state, reflecting the situation of the game on the CPU's computing requirements;

2. High-resolution + high-effect settings, if the game is stuck, indicating that the graphics card performance is not good. In high-resolution and high-efficiency operations, modeling, maps, and physical features rely on more GPUs;

Note: If the memory capacity of the computer is too small, how will the card will be ... ...

The performance changes of the GPU in recent years are obviously faster than those of the CPU. We do not believe that we can look for the game three years ago. Compare the current game with the latest games, especially the light and the ground, and the game screen will be improved. very obvious. Well, Xiao Bian said so much today today, blessing everyone to mine 120 frame lightning fast!
