HD4870 X2 previewed

TT: One thing that we noticed with CrossFire: the drivers there haven't been very efficient. Two cards don't exactly add up anywhere close to the theoretical 200 per cent performance leap that we should be looking at. We haven't been able to go beyond 30 per cent; that's really on the lower side.

R: A couple of things here. Games, when you play them at resolutions that are not entirely GPU-bound, then you won't see more than 35-40 per cent. When you make the game completely GPU-bound, say you're running at a resolution higher than 1600 x 1200, you'll start to see the scaling.

TT: In CrossFire, most of the motherboards, almost 95 per cent of them, support 8X mode instead of 16X each (PCI-E bus speed). Is 8X good enough?

R: If I answer this from a forward looking viewpoint -- yes more bandwidth is always good, but from an existing games stand point, it is good enough, that's what we find

TT: Good enough even for the 4-series?

R: Yes, because our drivers and the games, at least the last generation games, they've been optimized to avoid traffic between GPUs. But my prediction is that moving forward it will be important that there's more bandwidth between GPUs. So if you want to use this configuration for a long time, then you'll have to go for 16X.

430W für eine Grafikkarte. Das ist einfach nur mehr komplett gaga.

430W für das komplette System unter Load kommt hin. Die Karte selbst hat weniger, auch wenn es nicht viel weniger als 300W ist.

hachigatsu, dein Post ist eine Frechheit für unser aller Augen. Den Sinn von +lol+ und dem gesamten anderen Schmutz kannst du dir beim nächsten Post bei einer Auszeit genauer überlegen.

@ Mat.. Wenn das für dich ein grund is auszeit zu geben.. bitte tu dir nix an... Ach muss es schön sein forummod zu sein *lol*
