P-State Coordination
In HW_ALL mode, the processor hardware is
responsible for coordinating the P-state among logical
processors dependencies. The OS is responsible for
keeping the P-state request up to date on all logical
processors.
In SW_ALL mode, the OS Power Manager is
responsible for coordinating the P-state among logical
processors with dependencies and must initiate the
transition on all of those Logical Processors.
In SW_ANY mode, the OS Power Manager is
responsible for coordinating the P-state among logical
processors with dependencies and may initiate the
transition on any of those Logical Processors.

CPU Speed
The processor speed is the speed at which a
microprocessor executes instructions. Clock speeds are
expressed in megahertz (MHz), with
1 MHz being equal to 1 million cycles per second. The
faster the clock, the more instructions the CPU can
execute per second.
