There really is not much competition here:
http://www.nvidia.com/object/what_is_cuda_new.htmlWe are not talking about 10% performance increases. This platform has actualized up to 1800% performance gains on math heavy applications.
Remember the math co-processor on the old 386? Yeah those are now standard on every desktop computer. You never see it. It's on die with the CPU. I would say that this is a similar advancement.
