De nieuwe Athlon XP's zouden naast de core revisie ook gebruik maken van een lichtjes gewijzigde PR-rating volgens X-bit Labs
The Taiwanese mainboard makers supporting very closely AMD Company told that the working frequency of the upcoming AMD CPUs would make 2.13GHz for the 2600+ and 2GHz for the 2400+. In other words AMD decided to use a new formula to calculate the processor rating from now on. The changes made to the formula are most probably connected with the fact that simple increase in the core clock frequency doesn’t provide any stable performance growth any more.De oude formule om de PR rating te bereken was : 3 x Frequency / 2 – 500 terwijl de nieuwe 3 x Frequency / 2 - 600 zou zijn
