Even CPUs designed for a higher turbo-boost frequency have disproportionate power usage increases at their highest freq, compared to the marginal perf gains. I suspect the rush to idle must on tons of model be an equilibrium esp in freq selection if you really want to optimize for power consumption. Probably why user selectable power plans make sense.
- zozbot234 5y agoThat might definitely happen on some modern CPU's where turbo boost frequencies might be overvolted, and idle frequencies conversely undervolted. But even then, the optimal frequency is going to be relatively high because these dynamic voltage variations are going to be quite limited.
