I hope you realize what you say is utterly sutpid.

My original point is that you won't see double transistor count after a die shrink. Sure, manufacturers want to maintain an edge over their competition by rearchitecting the core or making other enhancements, but it's just naive to think that a core shrink from 40nm to 28nm will yield double performance.
Thanks for your super smart insight though
It is not. Do not forget that there are two items at the same time:
* More transisteos per surface
* Higher clock speeds possible.
Find that bad argumentation? Look at what happens to the CPU front - same thing.
Even with only 50% more transistors they can more than double performance by ramping up clock speed.
