Graphics processing unit

A specialized electronic circuit that performs rapid mathematical calculations for rendering images.

Graphics processing unit (GPU) is a type of electronic circuit, a programmable logic chip or processor specially designed and optimized to perform mathematical computations rapidly to manipulate and alter images.

GPU is optimized for display functions. It renders images, animations, videos and gaming for the computer's screen. It is vital for rendering and smooth decoding 3D animations and videos. It performs parallel operations on multiple sets of data. It is increasingly used as vector processors for non-graphics applications that require repetitive computations.

GPUs are found on plug-in cards in a chipset of the motherboard or in the same chip as the central processing unit (CPU) in a desktop computer. GPU includes its own memory random access memory (RAM) in stand-alone cards while GPUs in the chipset or CPU chip shares main memory with the CPU.
