The Graphics Processing Unit, if available, takes load from the CPU and thus helps make graphics rendering faster.

What is a GPU?

This is an abbreviation for "Graphics Processing Unit", and thus points to a "co-processor" taking load from the CPU. Quoting Wikipedia:

A graphics processing unit (GPU) [...] is a specialized electronic circuit designed to rapidly manipulate and alter memory to accelerate the building of images in a frame buffer intended for output to a display. GPUs are used in embedded systems, mobile phones, personal computers, workstations, and game consoles. Modern GPUs are very efficient at manipulating computer graphics, and their highly parallel structure makes them more effective than general-purpose CPUs for algorithms where processing of large blocks of data is done in parallel.
