You're right, I was being overly sloppy with my wording here. I was only referring to the uniform electric resistance part of energy losses that would be gone. My understanding had always been that the latters makes up a significant portion of the total energy CPUs consume because we're still many orders of magnitude away from the Landauer limit, https://en.m.wikipedia.org/wiki/Landauer%27s_principle .

To get there we wouldn't just need a superconductor, but a supersemiconductor that could switch instantly between infinite and zero resistance. I don't think we're anywhere near that, let alone one at room temperature.

From the top my head, most power is dissipated in switching, then leakage (for that we would actually need higher resistance in the transistors) and only then resistive losses in powerlines.

Interesting, I stand corrected then!
