This is false. It's a common misconception however - the rating system actually refers to AMD's own internal rating scale. The fact that the 3200+ was aimed to compete against a P4 3.2 GHz is mere coincidence. <tongue in cheek>
But you're right about one thing - clock speed doesn't matter, at least not entirely by itself.
Compared to a Xeon dual core and an Athlon XP 3200+ CPU, yes the Xeon would be faster, but only marginally.
