Lidt om P states fra wiki:
Performance states While a device or processor operates (D0 and C0, respectively), it can be in one of several power-performance states. These states are implementation-dependent, but P0 is always the highest-performance state, with P1 to Pn being successively lower-performance states, up to an implementation-specific limit of n no greater than 16.
P-states have become known as SpeedStep in Intel processors, as PowerNow! or Cool'n'Quiet in AMD processors, and as PowerSaver in VIA processors.
P0 max power and frequency
P1 less than P0, voltage/frequency scaled
Pn less than P(n-1), voltage/frequency scaled
Ved hjælp af værktøjet kan man ændre indstilling på P states for de individuelle kerner hvis det er det man ønsker. Nu har jeg kun brugt det til at spare strøm, men man kan også bruge det til simpel overcloking på BE udgaverne.
