Graphics processing unit

A Graphics Processing Unit or GPU (also occasionally called Visual Processing Unit or VPU) is the microprocessor of a graphics card (or graphics accelerator) for a personal computer or game console. Modern GPUs are very efficient at manipulating and displaying computer graphics, and their highly-parallel structure makes them more effective than typical CPUs for a range of complex algorithms.

A GPU implements a number of graphics primitive operations in a way that makes running them much faster than drawing directly to the screen with the host CPU. The most common operations for early 2D computer graphics include the BitBLT operation, usually in special hardware called a "blitter", and operations for drawing rectangles, triangles, circles and arcs. Modern GPUs also have support for 3D computer graphics, and typically include digital video-related functions as well.
