IIRC with the high frequencies of modern processors switching losses tend to be a larger factor than resistive losses. If you can remove the resistive losses that leaves you with a greater heat budget from switching losses which might help drive up frequency even more.

Dynamic current does not flow freely in superconductors, only direct current. So it would help for power circuits, not for data lanes.

Switch losses are also resistance losses, they just get amplified by things like the skin effect.

If you have a room temperature superconductor, does that mean you can make a superconducting transistor from it?
