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. See also: ACPI C & P states Consider this: <BlockQuote> <http://www.intel.com/support/processors/tools/piu/sb/CS-031497.htm> 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. </BlockQuote> <http://www.intel.com/technology/itj/2006/volume10issue02/art03_Power_and_Thermal_Management/p03_power_management.htm?wapkw=Power%20Management> <BlockQuote> 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. </BlockQuote> <http://www.amd.com/us/products/desktop/processors/phenom-ii/Pages/phenom-ii-key-architectural-features.aspx> 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.
