No, it really wouldn't. Clock speed is as much restricted by light speed delays as it is by transistor switching speed.

- Symmetry 14y agoOk, I'm going to disagree with you here. Speed of light delays cause latency when you're talking about large structures like caches, but they're not even the biggest factor in L3 with current processes. If we were clocking things as fast as nanotubes allow then we probably would find speed of light delays dominating latencies, but increased latencies will only eat a proportion of the gains from higher clock speed, and that's what we have branch predictors, prefetchers, and deep OoO engines for. Unless you were talking about clock skew between the exit points of your h-tree?
