Am just thinking out loud and am very hungry & maybe not making sense... but...

Faster could have a bearing on cost though - if you made cores that ran 4x faster for the same power, could you have 4x fewer? I know most of the area is not cpu cores, but there are a lot of gpu 'cores' on modern chips and if you could make them substantially faster per unit, then you could reduce area & cost?

I know that graphics is easily parallel and a design with many slower, lower powered gpu 'cores' has better power characteristics than one with fewer faster, more power hungry ones,
