The full English name of GPU is Graphic Processing Unit, which is translated as "graphics processor" in Chinese; GPU is the "brain" of the graphics card, which determines the grade and most of the performance of the graphics card. On the mobile phone motherboard, the GPU chip Usually it is next to the CPU chip.

#The operating environment of this article: Windows 7 system, Dell G3 computer.

I believe many people are not unfamiliar with CPUs, but many people don’t know what a GPU is? Let’s summarize what is a GPU?

1: What is GPU

GPU is the abbreviation of graphics processing unit. It is a semiconductor chip (processor) that can perform rendering of 3D graphics and other images. As a semiconductor chip installed on personal computers and servers, the GPU is the central processing unit of the PC or server and is used to describe images such as 3D graphics. As for the calculation processing regarding the depiction of 3D graphics, the CPU leaves it to the GPU. [Recommended reading: What is cpu

Recently, many GPGPU graphics processing units have appeared for general computing, which take advantage of the high performance of GPUs. Computing performance to perform effects other than 3D graphics, by using GPGPU, server performance higher than that of a supercomputer can be built at a lower cost.

Two: The difference between GPU and CPU

CPU and GPU both perform the same "computing process" required for PC and server operation, CPU is the same as PC or The corresponding brain of the server, GPU is a brain specialized for image description. However, image processing experts sometimes perform other computational processing (GPGPU). As follows:

What is GPU

For example , in a 3D game, the image is projected on the monitor as if it is flowing. This process requires a lot of calculations by the GPU. However, a 3D game cannot be built just by projecting the image. Various processing is required, such as reading the game from the hard disk. The CPU is responsible for describing these videos based on the data and processing commands that the user inputs with the keyboard and mouse according to the program. The CPU relies on the GPU for image rendering.

GPU is a processor suitable for conventional and large-scale computing processing in order to render images , one of the CPUs is a command processor that processes information sent from the entire computer, including HDD, memory, operating system, programs, keyboard, mouse, etc. For example, the CPU performs better in complex processing if the CPU is executing the entire process Commander, you can compare the GPU with a factory that quickly processes a large number of forms. The difference between the two is the number of cores in the above table.

三: GPU structure and processing capabilities

The GPU is installed on a component called the graphics board, which is the component displayed on the monitor in the computer. Connect it to the personal computer, the CPU and memory installed on the graphics board, etc. The component is called the motherboard and responds to commands from the CPU on the motherboard so that the GPU renders the image. There is also a so-called "built-in GPU" where the GPU is built into the chipset installed on the motherboard. As an advantage of using onboard graphics, saving money is achieved. On the other hand, the image processing performance of a graphics board is much higher. When using 3D graphics, it is recommended to install a graphics board.

The above is a complete introduction to what a GPU is. If you want to know more For more information on operation and maintenance, please pay attention to php Chinese website.
