Only it's not purely specialty hardware in this case. It's a massively parallel computation subsystem that happens to be also able to generate a video signal.

Only it's not purely specialty hardware in this case. It's a massively parallel computation subsystem that happens to be also able to generate a video signal. This really makes sense in a way. I once read in a paper that the best thing to have when faced with the task of performing an arbitrary calculation with maximal speed is 1) one core that's a fast as possible (for stuff that must be calculated sequentially) and 2) as many as possible slower cores (for stuff that can be calculated in parallel).
