Cinebench Performance Per Watt
Looking at the Cinebench performance per Watt numbers, as a guide for the operating and productivity performance efficiency of each processor, Ryzen 5 7600X is pretty poor out of the box. This is by virtue of the default voltage that results in relatively high power draw for its performance level.
The tuning modes of Eco and Curve Optimiser are both far better thanks to their more sensible operating voltages that rein in power consumption. Intel’s Core i5-13600K operating in its 115W is still considerably more efficient, though.
