GPGPU

use of a graphics processing unit to perform computation in applications traditionally handled by the central processing unit

GPGPU stands for General-Purpose computation on Graphics Processing Units. It refers to using a Graphics Processing Unit to perform tasks normally done by a central processing unit.

GPUs are stronger than CPUs of the same price only for jobs that can be split up into many subtasks internally. Like playing videos and rendering graphics in video games. Likewise, CPUs are stronger than GPUs of the same price for jobs that cannot be split up.
