Enhanced Intel SpeedStep® Technology
Enhanced Intel SpeedStep® Technology enables OS to control and select P-state. The following are the key features of Enhanced Intel SpeedStep® Technology:
- Multiple frequencies and voltage points for optimal performance and power efficiency. These operating points are known as P-states.
- Frequency selection is software controlled by writing to processor MSRs. The voltage is optimized based on the selected frequency and the number of active processors IA cores.
- Once the voltage is established, the PLL locks on to the target frequency.
- All active processor IA cores share the same frequency and voltage. In a multi-core processor, the highest frequency P-state requested among all active IA cores is selected.
- Software-requested transitions are accepted at any time. If a previous transition is in progress, the new transition is deferred until the previous transition is completed.
- The processor controls voltage ramp rates internally to ensure glitch-free transitions.
