According to your logic, the 90nm Smithfield must dissipate 230W

Then you have a misunderstanding of 'logic'.

Nowhere did I assert such a thing. In fact, I stated that the 2.8-3.2GHz Smithfields are to have 130W TDP.

Single core 90nm Prescott at 4GHz would have 150W TDP, per Paul Otellini.

If he isn't lying, then dual core 90nm Prescott at 4GHz is about 300W TDP.

Now, at the same speed, how much power do you think 65nm will save over 90nm?

25%? Okay, then we have a 225W dual 4GHz Dempsey. Still, to put it mildly, "problematic".
