Apparently, RV770XT with GDDR5 (160W) will run 1.3X faster than RV770PRO with GDDR3 (110W). Two key factors that contribute to the difference in performance between the 2 cards: a 100MHz core clock difference and a faster GDDR5 at 1.96GHz vs GDDR3 at 1GHz. Interesting, RV770PRO will run 1.25X faster than GeForce 8800 GT/9800 GT while RV770XT will run 1.25X faster than GeForce 9800 GTX.
ATI RV770 performance figures leaked?
