A Dothan clocks at 56% of the rate of Prescott with a pipeline perhaps 40% of the length of Prescott's pipeline and you think Dothan's transistors can be 10 or 20% slower?

The clock rate increase from a longer pipeline models much closer to the sqrt of the ratio. So that extra 2.5 factor pipeline length should allow Prescott to clock 58% faster.

That would put it at 2x1.58 or 3.16 GHz. 3.6/3.16 is in the 10 to 20% range, but reality is closer to 10%, since 3.6 GHz Prescott is even rarer than a 2 GHz Dothan.
