In general, how does CPU utilization correlate with CPU power draw?
- sandworm101 2y agoMore utilization = more power draw. Generally.
- Marsymars 2y agoAnd the more cores you load, the higher the total draw, but the lower the per-core draw.
- ngneer 2y agoPrecisely. Loosely speaking, CMOS power dissipation is governed by the equation P = alpha*F*V*V, where V is the voltage, F is the frequency of transistors toggling and alpha is an activity factor between 0.0 and 1.0, corresponding to how many transistors toggle. More utilization = more transistors toggling = more power draw. Generally.
