In light of this revelation at
XFX 7900 being sneaky with delta clocks that some manufacturers have different geometric delta clocks for their cards, i thought i'd download latest NiBiTor 2.7 and the current 7900GT/GTX bioses and see what clocks they have
edit: Actually could be slightly wrong in that XFX could be faster at 0 delta clocks since 7800/7900 have 3 clocks, geometric, rop/shader and 2d clocks for core
final 3d core clock made up of = ROP/Shader clock + geometric delta
ROP/Shader is throttle clock you see in nibitor images.
Only way is bench and see which is faster and which clocks higher
