I reposted on this - XP actually behaves the same way as 7.

Intel's own utility shows 1.66Ghz

In power management, if I set max processor state to 50%, Intels app
shows 0.99GHz, CPUZ shows 0.99Ghz with multiplier = 0.6, Win7 continues
to report 1.33GHz, and a Windows desktop processor monitor I'm using
shows 799MHz (I have tried a few and they all show the same).

Certainly inconsistency here.
