Geforce 7600 GT has 12 pipes at 560 MHz+
 

Geforce 7600 GT will still be 128 bit card but so also are the X1600XT/PROs. We reckon that 7600 GS is meant to fight X1600PRO and both G73 based 7600 cards will end up with a 128 bit memory interface.

I suspect that both 7600 GT and GS will be able to outperform the current X1600 XT and PRO cards and 7600 cards will be able to do 12 pixels shaders per clock. It is just enough to match ATI's offering.
