Chips customized for machine learning are specially trained for deep machine learning and have higher efficiency (computing power per watt).

Epu: power management chip

It is a chip responsible for power management such as conversion, distribution and detection of electric energy in electronic equipment system. It is mainly responsible for identifying the power supply amplitude of CPU, generating corresponding short rectangular waves and promoting the output power of the latter circuit.

The processor of the graphics card is called the graphics processor (GPU), which is the "heart" of the graphics card, similar to the CPU, except that the GPU is specially designed to perform complex mathematical and geometric calculations, which are necessary for graphics rendering. Some of the fastest GPUs integrate more transistors than ordinary CPU.

Most GPUs now have 2D or 3D graphics acceleration. If the CPU wants to draw two-dimensional graphics, it only needs to send an instruction to the GPU, such as "Draw a rectangle with the length and width of a×b at the coordinate position (x, y)", and the GPU can quickly calculate all the pixels of the graphics, draw the corresponding graphics at the designated position on the display, notify the CPU that "I have finished drawing" after drawing, and then wait for the CPU to send the next graphics instruction.

With GPU, CPU is freed from the task of graphics processing, and can perform more system tasks, which can greatly improve the overall performance of the computer. GPU generates a lot of heat, so a radiator or fan is usually installed above it.

GPU is the "brain" of graphics card, which determines the grade and most performance of graphics card, and is also the basis of the difference between 2D graphics card and 3D graphics card. 2D display chips mainly rely on the processing power of CPU when processing 3D images and special effects, which is called soft acceleration.

The 3D display chip integrates 3D images and special effects processing functions into the display chip, which is the so-called "hardware acceleration" function. The display chip is usually the largest chip on the graphics card (with the most pins). At present, most graphics cards on the market use graphics processing chips from NVIDIA and AMD-ATI.
