When Intel still advertised their consumer processors using the clock 
speed, AMD labeled their processors with the clock speed of the 
equivalently performing Intel processor. However, neither Intel nor AMD 
currently push clock speed as a performance indicator afaik. Otherwise, 
it would be hard for Intel to explain why a Core Duo is "slower" than a 
several year-old Pentium 4.
