my 6850 and 6870 numbers were done on the 10.10 driver. if the 10.10 driver were magically doing something for cf then you would see that in the scores, which you apparently dont

we are using wow dx11 in this round of benchmarks, so maybe that caused the problem
Sorry if you explained this somewhere already, but I wondered how do you get a consistent testing environment for wow?

You misread. I said that the 10.10 drivers are the cause of the FPS loss.

I've tried running my WoW in both dx9 and dx11 with no difference in fps when crossfire is enabled, like your benchmarks my 6870 crossfire setup actually performs worse than a single 6870.

However when I had my 5970 on 10.5 catalyst, I was getting far higher framerates than with this setup... My conclusion is the 10.10 are at fault, sadly I can't backdate drivers as they arent compatible with the 6 series cards it seems.

I think what's caused the problem, is WOW being crappy.

@ above guy, it must be something other than drivers, the nividia cards have taken a dive to.

The hit the Nvidia cards have seen are probably due to the new Liquid engine from patch 4.0.1 - it will obviously hinder fps abit, but nowhere near as much as the crossfire benchies are suggesting.

It's 10.10, typically ATi have screwed up yet another driver release, as I said 10.11 better be working as intended or the competition will be getting tougher for ATi.


Powerful hardware is great, but when you cant utalize that hardware then whats the point? :\

... I have a great idea; how about AMD asks nVidia to code their drivers for them, and in return AMD can teach nVidia how to manufacture proper GPUs? ... genius, right? :D ...

So I just uninstalled catalyst 10.10 and installed the 10.10c hotfix - FPS in WoW has now doubled :)))

It seams like most 6870's can get 1ghz core with a little more voltage, i wonder what the results would be like if both are overvolted to get the max clocks.

Don't just look at the overall guys, look at the demanding games and high resolution... The crossfire scaling is EXCELLENT

Do you really need to play Supreme Commander 2 at 1280x1024 at more than 120fps?
I just hope the 6970 can do about or better :). Any date on that yet ?.

Shame there is no power consumption charts. Wish i had $50 to give w1z so he could get a ZM-MFC2 even if is total system usage at least there be some numbers then.. Maybe even a kilawatt :p.

In crossfire, can't you say the Maximum would just be double that of a single card? Same thing for idle.
