When I was bored, I saw that a cpu and gpu felt as if the difference between cpu and gpu was a letter, but there was a lot difference in the real thing. I believe everyone knows that cpu is the central processor of our computer, so everyone should know that gpu is a graphics processor. So what is the difference between them, the following small series for everyone to summarize the cpu full name Central Processing Unit Chinese name: CPU CPU is generally composed of logical arithmetic unit, control unit and storage unit. Some registers are included in the logic operation and control unit for temporary storage of data during processing of the data by the CPU. Although the CPU has multiple cores, the total number does not exceed two digits. Each core has a large enough cache; the CPU has enough digital and logical operation units, and assists the hardware with many acceleration branches to judge even more complicated logic judgments. Cpu has super logical ability. The CPU is good at processing tasks with complex computational steps and complex data dependencies, such as distributed computing, data compression, artificial intelligence, physical simulation, and many other computing tasks. The GPU is called the Graphic Processing Unit. Supports T&L (Transform and Lighting, polygon conversion and light source processing) display chips from the hardware, because T&L is an important part of 3D rendering, its function is to calculate the 3D position of the polygon and process the dynamic light effect, also can be called For <;Geometry Processing”. A good T&L unit can provide detailed 3D objects and advanced lighting effects; except for most PCs, most of T&L's operations are handled by the CPU (this is called software T&L ), due to the many tasks of the CPU, in addition to T&L, it also needs to do non-3D graphics processing such as memory management, input response, etc., so the performance will be greatly reduced in the actual operation, often the graphics card waits for CPU data. Its speed of operation is far from the requirements of today's complex 3D games. Even if the CPU's operating frequency exceeds 3GHz or higher, it does not help much, because this is a problem caused by the design of the PC itself, and has little to do with the speed of the CPU. The gpu exists as a subordinate processor, and it mainly deals with the work related to graphics computing in computers. The GPU has a much higher number of cores than the CPU, which is called a many cores, but each core has a relatively small cache size. The GPU's digital logic unit is also small and simple (the GPU is always weaker than the CPU in floating point calculations). Gpu has a very high computing speed. GPU is good at image processing, so gpu is mainly used in the fields of images and video games. The power consumption of the GPU far exceeds that of the CPU. I think this can be used as a short answer to the college entrance examination, hehe. The teacher of the volume may wish to consider this article from [System Home] www.xp85.com
