What does the GPU in the graphics card mean?

Graphics processing unit (GPU), also known as display core, visual processor and display chip, is a kind of microprocessor specialized in image and graphics related operations on personal computers, workstations, game machines and some mobile devices (such as tablet computers and smart phones).

GPU reduces the dependence of graphics card on CPU and does some work of original CPU, especially in 3D graphics processing. The core technology adopted by GPU is hardware T&; L (geometric transformation and illumination processing), material mapping and vertex blending in cubic environment, texture compression and T& mapping, dual texture four-pixel 256-bit rendering engine, etc. , and hardware T &；; L technology can be said to be the symbol of GPU. The main manufacturers of GPU are NVIDIA and ATI.

Extended data:

The workflow and physical structure of CPU and GPU are similar, and the work of GPU is more single than that of CPU. In most personal computers, GPU is only used to draw images.

If the CPU wants to draw a two-dimensional graph, it only needs to send an instruction to the GPU, and the GPU can quickly calculate all the pixels of the graph and draw the corresponding graph at the designated position on the display. Because GPU generates a lot of heat, there is usually a separate heat sink on the graphics card.
