Answer by John U for What limits CPU speed?
As well as all the other answers, there are also a few other considerations which may not affect CPU speed directly but make building anything around that CPU quite difficult; In short, above DC, radio...

The answers to your questions are: Yes, there is a physical limit to CPU speed. The highest theoretical limit will be set by how fast a "switch" can switch states. If we use the electron as the basis...

There are three physical limits: Heat, gate delay and the speed of electric transmission. The world record on the highest clock speed so far is (according to this link) 8722.78 MHz The speed of...

Answer by fuzzyhair2 for What limits CPU speed?
Practically, what limits CPU speed is both the heat generated and the gate delays, but usually, the heat becomes a far greater issue before the latter kicks in. Recent processors are manufactured using...

So one question is: Is there a physical limit to CPU speed? That depends highly on the CPU itself. Manufacturing tolerances result in the fact that the physical limit is a bit different for every chip...

I've recently talked with a friend about LaTeX compilation. LaTeX can use only one core to compile. So for the speed of LaTeX compiliation, the clock speed of the CPU is most important (see Tips for...
