AMD To Launch RV770 On June 18th

From the reviews I've seen by far of the 2xx stuff, I am actually beginning to believe that the Crysis game engine is actually very badly coded, like everyone has been saying (and to be honest didn't really want to believe). It just scales so badly compared to other engines its crazy. I really don't think it can be used as a benchmark for the latest cards anymore.

I thought there had always been a problem with crysis and xfire with older cards and that guy on XS has those same results with one 4850 so xfire is not working so not a fair result. Need to get a benchmark from a game that handles xfire\sli and then see what we get.

Is there any truth to the rumour that the 4870X2 will do away with crossfire completely and have some sort of internal load balancing method?

Also, is it true that it will share its memory between the two cores?

I frakkin' hope so :D

If so, the " raw performance" won't quite compare with a x-fire rig (since the memory bandwidth will be the same as a single-GPU card, rather than being doubled as with x-fire), but all of the memory will be usable, and the multi-GPU issues, which all arise from memory redundancy, will be gone!

That will be a very small price to pay for slightly reduced performance in memory bandwidth limited scenarios.
 
I found a World in conflict test with everything maxed to compare to the 4850 xfire results

This puts he HD4850 xfire around 2FPS lower than the 280 on average and slightly above the GX2. Also bear in mind the 4850 crossfire uses 4xAA but there is no mention of AA in the tweaktown review..

True, no mention in the review either could be just High settings.

Well according to someone at Beyond3D

Crysis Very High DX10 @ 1920x1200 4xAA ~ 23 FPS on the 4850 CF
on GTX 280 at same settings (from computerbase.de) ~ 16 FPS

Though looks like we aren't getting the 4870 for a little while after the 4850's
