Over the past several years, AMD has successfully fought the PR battle with Intel to convince OEMs, PC manufacturers, and consumers that frequency or megahertz (MHz) is not the right metric when evaluating the performance of processors. The essence of the argument is that processor designers can use architectural design techniques that improve the performance of applications running on the processor, without increasing the operating clock rate of the processor. In fact, processors with high clock rates dissipate much more power since power dissipation (P) is proportional to operating frequency (f). In the ultimate acknowledgement to this argument, Intel today ships dual-core chips that run at lower MHz than older generation processors.
