I've looked around a bit here and I may have missed it, but why are we so locked down on GPU GHZ? I know from the overclockers that heat is the enemy and depending on how far you want to up the GHZ it can get very expensive to dissipate that heat away. I know also that with a die shrink you can count on improved efficiency and less heat for the same performance as the last generation. My question is this. Would it be possible to die shrink a GPU and keep the same number of transistors but spread them out over the size of the last generation GPU to offer a greater area of heat dissipation? I'm not an engineer and I'm sure that my simple idea has been passed over for good reason but I wonder about this.
