Notes
As you can see, the X850 XT PE was clocked at 540/587, with the Club3D X800 XL clocked at 398/493. For comparison purposes, the X850 XT Platinum Edition was also clocked down to 398/500 to see what effect, if any, being native AGP at the same clocks as X800 XL would have. 500MHz was chosen on the memory to offset its slower memory timings at the same memory clock, compared to the 493MHz GC20-equipped X800 XL.Both R481 and R430, in their respective X850 XT PE and X800 XL guises are full four-quad parts that differ only in clock frequencies; if you could clock an X800 XL to 540/587, you'd have an X850 XT PE.
