Update: The link between power and frequency seems to be complicated. See e.g. https://physics.stackexchange.com/questions/34766/how-does-power-consumption-vary-with-the-processor-frequency-in-a-typical-comput https://physics.stackexchange.com/questions/34766/how-does-p... First answer says P goes linear with f, based on theory. Second answer goes for cubic or worse based on some deep papers, but a comment says this is dated. Third answer has a graph from real-world measurements which is clearly worse than linear, and a comment saying there is an exponential part somewhere there too, but it is swamped by linear factors. WIkipedia, by the way, goes for linear - https://en.wikipedia.org/wiki/CPU_power_dissipation#Sources https://en.wikipedia.org/wiki/CPU_power_dissipation#Sources I think the most realistic answer I can give is: It is complicated, and OP is a very good nerd sniper ;-)
