RV770 Preliminary Performance Revealed
We have received some preliminary performance numbers from CJ for Radeon HD 4870 and 4850 vs the current GeForce 9800 series lineup. 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.

u can argue about just anything.
1.625 1.25 1 1.3
OR
5.175 2.25 1 2.3
Okay, 5 times an 8800 gt??! Stop skiping math class people. Either way they are probably fake.
it means whatever the speed of geforce 8800gt is times 2.5
what he meant to say is "it's 1.25X as fast as the geforce 8800gt. which would mean the speed of geforce 8800gt time 1.25
there is no opinion about it. unless you use some form of english that is used on some other planet, those are the facts
