VDC vs. GPU
The difference between a display controller, a graphics accelerator, blitter, and a graphics processing unit (GPU) is often blurred by examples that are called one but have some features of another class. It is not always clear when a particular video chip is a video display controller and when it is a video display processor. For example, the TMS9918 may be referred to either way, depending on the source.
