The vast majority of CPU power dissipation is from dumping gate capacitance to ground - not the resistance of the interconnects. It's akin to filling (very small) buckets of water and dumping them back out billions of times a second. Zero resistance interconnects would allow us to charge those gates faster resulting higher clock speeds though.
