The Adreno series of graphics processing units (GPUs) are manufactured by Qualcomm Inc. 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.
