intel hired quite some nvidia engineers, if all they do is rebuild G200 on intels 45nm process they would probably be enough for a mainstream product already... the thing is, its not about building a fast gpu... intel could do that but it would accelerate them losing grip as x86 fades away... what they want is build a cpu that can act as a gpu... a software emulated gpu... and one that is at least as fast as a propper gpu... THAT is all still possible and a matter of resources... BUT, intel wants it to be financially feasible and possibly even wantsd to mkake money with it...

THAT might be something that is actually impossible... itll either be slower or cost more than a conventional gpu... you cant beat a fixed function processor in its own game with a general purpose processor at the same transistor budget...

its like expecting an SUV which can drive everywhere and is sortof a general purpose car, to beat an F1 car, which can only drive on very flat streets, but does so at insane speeds... now you either build an insane suv mutant at insane costs, that can drive as fast as a f1 car on a racetrack, but can ALSO drive everywhere else... or youll lose the race on an f1 track... obviously...

im confused how intel thought this was going to work... with their mfc advantage in their sleeve that might work out, but apparently they wanna use the cheap old 45nm fabs for lrb once cpus have moved to 32nm? 0_o
Well the short answer is that Intel artificially handicapped themselves by demanding x86 Compatibility. Ati and nVidia are completely free to do what ever they desire with the underlying architectures and modify them at a minutes notice to improve performance. While Intel is stuck supporting every single bad idea introduced into x86 since the introduction of the 8086.
It is a long known historical fact that legacy ISAs always have a lower performance per transistor compared to completely new ISAs which often have the benefits of learning from the mistakes of previous ISAs.
