The implication was that a graphics accelerator does simply that: it accelerates graphics. Five years ago, PCs and computer workstations had graphics accelerators, not graphics processing units (GPUs). Not only has performance increased, but also the quality of computation and the flexibility of graphics programming have steadily improved during that same time. Five years represents the doubling of performance ten times-that's two to the tenth power, a factor of one thousand! A factor of two is certainly exciting enough, but more exciting is the wonder of compounding. The rendering rate, as measured in pixels per second, has been approximately doubling every six months during those five years. Over the past five years, GPU technology has advanced in astounding ways, and at an explosive pace. Now is an excellent time to be working in the field of computer graphics.
