[vr-zone] RV770 Preliminary Performance Revealed

post #1 of 48

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 30% 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

THe 9800GTX is $300 on Newegg and the HD4870 will come out at $220. CrossFire scales better than SLI, never think otherwise. You can CrossFire FOUR RV770's and only three G92-420s.

wait... this isn't looking good.

1.3 times faster than a 9800GTX (8800GTS)? i hope they overclock well...

So great value for money but not really a step forward?

Oh well.. Wait for next generation, then.

How colorful.

So 25% faster in Oblivion if resolution is 800x600 and all effects minimum or running Crysis at 2560x1536 16XAA 16AF?

Or perhaps 25% more theoretical GigaFLOPs?
post #10 of 48
wow....no one is happy with a 25% increase? i duno about you but if these cards retail for around 200 bucks i will be estatic.
