Definition of A graphics processing unit (GPU)

A graphics processing unit (GPU), also known as a display core, vision processor, or display chip, is a microprocessor that specializes in performing image and graphics related operations on personal computers, workstations, game consoles, and some mobile devices (such as tablets and smartphones). The GPU reduces the dependence of the graphics card on the CPU, and carries out some of the original CPU's work, especially in 3D graphics processing, the core technologies used by the GPU include hardware T&L (geometric conversion and light processing), cubic environment material mapping and vertex mixing, texture compression and bump mapping, dual texture four-pixel 256-bit rendering engine, etc. Hardware T&L technology can be said to be the hallmark of GPU.
