bowman, I think the worst decision they made this generation was adding FP64 seperate units instead of more shader power.

They want 1 chip to be used in several cards (Geforce, Tesla, Quadro) but unlike ATI's R6XX the shader units are much less flexible, and the whole architecture is less flexible (512-bit bus = 32 ROPs, no talk and no override, etc)

The fact that you see ATI refining, refining and refining their once also-ran architecture to something that's truly amazing in terms of engineering, is a real testament even when the whole R&D budget went down.

nVidia... I'm sorry I just can't say the same thing. Instead of making 2 chips, one big gamer chip and a mainstream/Tesla GPGPU chip (together), they made 1 instead.
