Radeon X850 XT PE Review @ Beyond3D

"Being that there are few differences between Radeon X800 and X850, the newer R480 chip doesn't significantly differ from R423 that preceded it. As there are no major process differences ATI are limited in the gains they can make in this regards, which probably explains the fairly incremental increase in core clock speed."
*Gasp*! a factory overclocked chip?? perish the thought.
