Alan, you realize that if you're right, the horrid Prescott power (and it won't get *that* much better with D) implies that Dothan power dissipation will also be crappy.

What the heck do the Dothan and Prescott have in common
other than their process? These are vary different designs
in many ways. Process isn't destiny. DEC manufactured its
SA110 and EV6 RISC processors in the same fab using the
exact same process. These two chips ran at 3.1 W/GHz and
187 W/GHz respectively. How useful would power/frequency
data for one chip be in predicting the power dissipation of
the other at a given frequency on the naive basis they used
the same process?
