GPU means “Graphics Processing Unit”. A Graphics Processing Unit is a co-processor that takes on graphical calculations and transformations so that the main CPU does not have to be burdened by them. The use of a GPU can greatly increase the performance of a device, especially when used for tasks such as 3D gaming. A GPU can be a stand-alone chip or, as is more often the case, integrated into a complete chip design that includes one or more CPU cores. NVIDIA's GeForce and the Adreno by Qualcomm are two examples of GPU families used in the mobile industry.
