In Depth: Intel processors: everything you need to know

Not so long ago, processors were judged largely by raw clock speed alone, a measure of how many calculations the chip is capable of performing in the space of a second. As megahertz (MHz) speeds have given way to today"s faster gigahertz (GHz) processors, however, there"s more to consider than just how speedy a slab of silicon can be at doing math.
