A Processor’s Clock Speed Is Just One Measure of Performance

Thw Washington Post writes The question I hear over and over from readers and friends goes something like this: “I need a computer for running Microsoft Office and browsing the Web, not much else. How fast of a processor should I get?”
It’s not hard to see where that query comes from. Decades of computing history have taught one lesson very well: The most important part of the computer is the processor, and the higher the processor’s clock speed, the better.
But this lesson plan badly needs a rewrite. First, ever-accelerating chip speeds have blown past the needs of many applications — even the slowest machine sold today can handle most everyday computing tasks without perceptible delay. And for those chores where chip performance does matter, clock speed isn’t the right measurement anymore. (full story)
