While true, that’d only be for a superconducting CPU. I doubt this material can both superconduct and act as a transistor, and even if it can, I highly doubt you could pack in anywhere near the amount we have in standard CPUs. So while we might replace a standard power supply with a superconducting one, and reduce heat that way, I don’t see any direct computing boosts from this. We could superconduct everything around a CPU, have superconducting wires, but the heat from a CPU is generated in the silicon.
It’ll be pretty nice to have 100% efficient PSUs, though. Definitely some gains there, just not the same revolutionary ones seen elsewhere.
