Problem
I was musing last night about computers and processors and this video of a 6-bit digital adding machine, and I know that 4 GHz seems to be the practical limit of mass-produced CPUs of the current era. Why is that the case? I was trying to imagine something like that 6-bit adding machine * 11 (ok, 1…

Fix for: How far do electrons physically move in a single clock cycle in a (theoretical) 4GHz processor?
Low Risk
It's not the speed of the electrons that matters, that's really slow, but the group propagation velocity of the electric fields that push them around, which is around 1/3 of the speed of light. Given that 2.4GHz has a wavelength of 12 cm roughly, th…
