FYI, CPU power management differs from those system power
management you mentioned.
e.g. Both Intel & AMD have differing cpu core power management
in their current multi-core products, that vary core frequency,
& / or shutdown some cores, .... (among other things they change
in the cores like supply voltage);
Some of them change without / beyond user control.

Power Management modes may interfere with speed detection
tests performed by the Processor Identification Utility.
Power management modes can result in a marginally higher
or lower reported frequency than the expected frequency.
AMD CoolCore™ Technology
Works automatically without the need for drivers or BIOS enablement.
Power can be switched on or off within a single clock cycle,
saving energy with no impact to performance.
I can't find one specific article at the moment, however IIRC,
it said there were some AMD flavors that will change
the core frequencies for thermal management,
independent of user controls.
FYI: For Win 7 & Vista, to lock the process to a specific core,
