Graphics Processing Unit (GPU)

A graphics processing unit (GPU) is a circuit containing electrical components which control the memory, graphics manipulation, and output of a computer or mobile device. Video cards expand the capabilities of a GPU by generating a feed of output images.

GPUs today dedicate the majority of their semiconductors, or transistors, to accelerating 2D buffering and rendering 3D computer graphics. The performance of a GPU depends on the size of connector pathways and the storage capacity of on-chip memory, among other factors. GPUs are increasingly being used to facilitate AI research and development, specifically to train deep learning neural networks.
