Talking NiBiTor 2.7 screenshots of 7900GT/GTX bios clocks

In light of this revelation at http://i4memory.com/showthread.php?t=2436 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

seems nearly everyone adhered to 50mhz and 20mhz delta for 7900GTX and 7900GT respectively except XFX

Hmm... so I guess you should take the advertised XFX clockspeeds with a grain of salt until you know what delta clock they're using?

The other thing that's strange out of that data is the very low clockspeed in 2D mode on the 7900GTX' compared to the 7900GTs ... what's going on there???

Any ideas on when NiBiTor will support the Gainward 7800GS+ 512MB AGP (24 pipes)?

Thanks
