Test Setup and Overclocking

PowerColor HD6990 Crossfire Review

Test Setup

Second verse, same as the first. Only this time we have ... two cards to play with *cue Toccata and Fugue*

PowerColor HD6990 x2
Intel Core i7-950 @ 4GHz
ASUS Rampage III Extreme
Muskin Joule 1200w
6GB Mushkin Redline
Noctua NH-D14
Windows 7 Ultimate x64


The PowerColor managed to overclock 25MHz better than we saw from the reference AMD model. Naturally there is an element of the silicon lottery involved, but 25 MHz is just that.

Who are we to thumb our noses at any performance increase. We're Overclock3D after all.

As this is still a reference design we're still plagued by the heat and noise issues we were on the AMD, but there are no fault at all of PowerColor who can only work with what they're given.

I wonder how it would perform in wather cooled conditions? Uderwise nice card, but a little hot and loud for my taste Quote

very nice - but however rich i think i am, i cannot justify paying over £1000 for two cards, just for an upped framerate.

although, on their own, they handle the benches very well, considering that they are dual gpu cards.

i think AMD have also overpriced them, as they offer no new technology. for that price i would expect DX12 (whatever/whenever that may be) Quote

Wow it might be expensive but crossfire performance is insane though that's a hell of a lot of money for two graphics card regardless of performance.Quote
