CPU decoder ring

There was a time when processors were relatively simple. You had a model name (Pentium, Athlon, Celeron...) and a clock speed, and that was pretty much it. With the Athlon XP, things started getting complicated. Suddenly, the number at the end of the name was no longer the clock speed. At first, you could sort of crib up a cheat sheet by starting with 1533MHz for the 1800+, then adding 66MHz for every additional 100 in the model number. Pretty soon, however, there were multiple chips with the same model number that differed in clock speed, cache size, and bus speed.
