Fastest 65nm was 2.6...

Thats what I'm saying.

Their maximum on 65nm was about 2.6-2.7 Ghz if they were to push frequencies and on 45nm the same core made it all the way to 3.7 Ghz.

To have the same freq. scaling they would need to start out with a 3.7 Ghz chip. Not that it matters with a different architecture...
