This site is a big proponent of AMD's new advertising gimmick, the PR rating. Aside from any subjective opinions on whether or not the methodology has any validity or not, here's a simple analysis of the assignment of PR vs. XP clock rate which easily proves it to be unreliable.
Accepting at face value AMD's assertion that a 1333 MHz XP is equivalent to PR1500+ we come up with a ratio of XP MHz vs. PR of:
1500/1333=1.125
So, using this factor, an XP processors running at their respective MHz should have PRs of:
1400*1.125=1575 not PR1600+
1467*1.125=1650 not PR1700+
1533*1.125=1725 not PR1800+
So, how can AMD claim the inflated PR ratings they advertise? And don't tell me it's more complicated than that because the only difference between the various XP processors is the clock rate which is a linear parameter. And note that, with each succeeding PR designation, the exaggeration of the PR becomes greater and greater. With the next logical release, an XP running at 1600 MHz, the PR rating will be a full 100 MHz higher than it should be - PR1900+ vs. PR1800+.
This is crap, pure and simple, and has no place in this industry. Unfortunately, since AMD has already launched this advertising gimmick, there's no way they can take it back.
