Goodbye mister Gigahertz
At the beginning of the computers driven craziness it was all easy - you could create your judgment basing only on one number. Speed of the CPU was the most important number in the computers, everybody were talking about kilo, mega and giga hertz. In times, where memory was working at the same speed as CPU, and each tick of processor was one operation made it was easy to say: this computer can perform millions of operations per second - and in those times it was true. Then everything got complicated, memory has stepped down and is always slower than the heart, some instructions required more ticks than other, but, still - hertz was a king. It was so important, that AMD was describing it's own processor with fake speeds, to corelate them with their main competitor - people were thinking that high frequency was the same as speed. Even at this point, you were able to judge which computer is powerful, basing only on this one number - they were designed to perform numerical...
