Intel® Speed Shift Technology

Intel® Speed Shift Technology is an energy efficient method of frequency control by the hardware rather than relying on OS control. OS is aware of available hardware P-states and requests the desired P-state or it can let the hardware determine the P-state. The OS request is based on its workload requirements and awareness of processor capabilities. Processor decision is based on the different system constraints for example Workload demand, thermal limits while taking into consideration the minimum and maximum levels and activity window of performance requested by the Operating System.
