Graphics Processing Unit. A chip or digital circuit designed specifically for processing graphics and generally providing the main processing power of a computer graphics card. Having much more graphics power and speed than central processor unit (CPU) chips, GPUs can take over many complex 2D and 3D image processing tasks from the CPU.

In the wider computer market, GPUs have transformed computer games, simulation and a whole host of complex digital displays. However, GPUs are not as versatile as CPUs and some graphics tasks may still need to go through CPUs or other specific processors.

In the media business, GPUs are used in a wide range of image processing equipment ā€“ such as picture color correctors and graders as well as the high-end television graphics equipment including that for live ā€˜3Dā€™ graphics and virtual sets.
