SpeedStep - Wikipedia
https://en.wikipedia.org/wiki/SpeedStep
Enhanced SpeedStep is a series of dynamic frequency scaling technologies built into some Intel microprocessors that allow the clock speed of the processor to be dynamically changed (to different P-states) by software. This allows the processor to meet the instantaneous performance needs of the operation being performed, while minimizing power draw and heat generation. EIST was introduced in several Prescott 6 series in the first quarter of 2005, namely the Pentium 4 660. ... The power consumed by a CPU with a capacitance C, running at frequency f and voltage V is approximately:.
