It has 48 pixel pipelines...!!! Compared to 7800GTX's 24, this seems a monster, but performance is not doubled. :roll:

leaving sli and cross fire setups i think both the x1900xt /xtx are just marginally better than the 7800gtx 512mb . but the perfomance gain for the ati cards huge in cross fire setups.
