[QUOTE=smokeandmirrors;2608377]Well in the early 00s, they said something about “current CPU technology” being able to achieve 4Ghz. I’ve been waiting that moment for a while now.[/QUOTE]
As a matter of fact, that has been achieved years ago. But that was when they decided that two 2.0 GHz CPUs would be more efficient than one 4.0 GHz CPU, so dual core was born. Then that 2.0 started creeping up to 3.0, then 4.0, until someone decided it was a good idea to make a quad-core processor. So the reason you don’t see 4.0 GHz is not because it is not technically feasible, but because it is an inferior product.
