Paul O. says 150W for a *single* 4GHz 90nm NetBurst core.

He should know, shouldn't he?

Here's an Intel VP on the Smithfield clockspeed range:

Separately, he admitted Smithfield's clock speed range would be lower than the top end of today's P4 CPUs, to ensure the new chips "operate in the same thermal budget". Intel's roadmaps put those speeds at 2.8-3.2GHz, well below today's 3.8GHz P4 570.

And the "same thermal budget", is actually a higher thermal budget of 130W:
