Tom's Hardware has written a piece with predictions of how the computer industry may evolve in the next ten years, it focuses specifically on the future of 3D graphics. You can read it over here.
Having been there from the beginning, I've seen the rise and fall of countless graphics manufacturers: S3, 3DLabs, Rendition, 3dfx, as well as board manufacturers like Orchid, STB, Hercules, the original Diamond, and Canopus. But as wild and crazy as the last decade was for visual computing, the next decade is going to be even more exciting, not only in what technology will offer to consumers, but in the upcoming arms race in visual computing.
A lot has been said about the impending death of the dedicated GPU. If you look at the history of dedicated upgrade products for consumer PC technology, they all eventually reach the point of diminishing returns and then integration. However, while it is inevitable that the dedicated GPU will eventually disappear, it’s not going to happen in the next decade.
