What is a GPU?

A graphics card's processor is called a graphics processing unit (GPU), which is the "heart" of a graphics card and is similar to a CPU, except that the GPU is designed to perform complex mathematical and geometric calculations that are necessary for graphics rendering . Some of the fastest GPUs integrate even more transistors than regular CPUs.

Most of today's GPUs have 2D or 3D graphics acceleration. If the CPU wants to draw a two-dimensional graphic, it only needs to send an instruction to the GPU, such as "draw a rectangle

with quickly calculate the All pixels of the graphic, and draw the corresponding graphic at the designated position on the display. After the drawing is completed, the CPU will be notified that "I am finished", and then wait for the CPU to issue the next graphic instruction.
With a GPU, the CPU is freed from the task of graphics processing and can perform other more system tasks, which can greatly improve the overall performance of the computer.
