Why CPU Frequency Stalled

In this paper, the cycle rate of the PC\´s central processing unit has been described. CPU clock rates peaked a few years ago and they aren\´t a very useful key to chip performance anyway. The clock keeps a processor\´s parts working in unison. The clocks are not worth the cost in terms of power consumed and heat dissipated. Intel calls the speed/power tradeoff a "fundamental theorem of multicore processors" and that\´s the reason it makes sense to use two or more processing areas, or cores, on a single chip.
