Members

Number

The system processor number.

MaxMhz

The maximum specified clock frequency of the system processor, in megahertz.

CurrentMhz

The processor clock frequency, in megahertz. This number is the maximum specified processor clock frequency multiplied by the current processor throttle.

MhzLimit

The limit on the processor clock frequency, in megahertz. This number is the maximum specified processor clock frequency multiplied by the current processor thermal throttle limit.

MaxIdleState

The maximum idle state of this processor.

CurrentIdleState

The current idle state of this processor.
