What is a "GPU" chip?

A GPU is a graphical processing unit. It is like a CPU (which is a central processing unit) except that its role is dealing only with the graphics. Say you are doing video editing or gaming; those are really GPU intensive applications, and so instead of the CPU handling those calculations and algorithms they get afforded to the GPU. In that way the computer runs faster because it is less of a task on the CPU.
