AMD's Radeon HD 6990: The New Single Card King

Ubisoft’s 2008 aerial action game is one of the less demanding games in our benchmark suite, particularly for the latest generation of cards. However it’s fairly unique in that it’s one of the few flying games of any kind that comes with a proper benchmark.
In opposition to Metro 2033, HAWX is not shader-heavy by any stretch of the imagination. Here it’s texturing and ROPs that leads the day, leading to architectural differences as the deciding factor. Compared to NVIDIA’s lineup this means the 6990 is behind even the GTX 570 SLI, while an apparent lack of memory bandwidth once again has it hugging the 6950CF. Surprisingly the lead over the 5970 is still strong at 21%.

I doubt it. That would be 80 dBA at ear level compared to whatever Ryan used. At ear level it's going to be a lot lower than 80.Still, that doesn't take away the fact that this card is insane...

The card needs 3 slots to keep cool and such. They should have made a 2.5-slotted card, but with a bit of a twist.Channel the AIR from the front GPU chamber into a U-duct, then split into a Y that goes around the fan (which can still be made bigger. The ducts then exhaust out the back in a "3rd slot". Or a duct runs along the top of the card (out of spec a bit) to allow the fan more air space. It would add about $5 for more plastic.
Rather than blowing HOT air INTO the case (which would then recycle BACK into the card!
OR - blowing HOT air out the front and onto your foot or arm.
Noise is a deal killer for many people nowadays.

That ductwork would substantially reduce the airflow, making a sharp turn like that would be a large bottleneck.burner1980 - Tuesday, March 8, 2011 - link
I´m always wondering why reviews always neglect this topic. Can this card run 3 monitors @ 1920x1080p 120 HZ. 120 HZ monitors/beamer offer not only 3D but foremost smooth transitions and less screen tearing. Since this technique is available and getting more and more friends, I really would like to see it tested.Can anybody enlighten me ? (I know that Dual link is necessary for every display and that AMD had problems with 120 HZ+eyefinity) Did they improve?

...with two slightly downclocked 6950s. Alternatively, a 6890, albeit with the old VLIW5 shader setup. As we've seen, the 5970 can win a test or two thanks to this even with a substantial clock speed disparity.The 6990 is stunning but I couldn't ever imagine the effort required to set up a machine capable of adequately running one... and don't get me started on two.

I'd love to see Jessica Alba's beaver, but that aint going to happen either.qwertymac93 - Tuesday, March 8, 2011 - link

Could someone please confirm if this card supports 30-bit colour?Previously, only AMD's professional cards supported 30-bit colour, with the exception of the 5970. I will buy either the 6990 or Nvidia's Quadro based on this single feature.
(Because somebody will inevitably say that I don't need or want 30-bit colour, I have a completely hardware-calibrated workflow with a 30" display with 110% AdobeRGB, 30-bit IPS panel and the required DisplayPort cables. Using 24-bit colour with my 5870 CF I suffer from _very_ nasty posterisation when working with high-gamut photographs. Yes, my cameras have a colour space far above sRGB. Yes, my printers have it too.)

Just a heads up for anyone buying the card and wanting to remove the stock cooler.... There is a small screw on the back that is covered by two stickers with (its under the two stickers that look like a barcode). Well removing that you will then notice a void logo underneath it... I just wanted to point it out to you all...Didnt bother us too much here seen as ours is sample but I know to some droppin £550ish UK is quite a bit of cash and if all you are doing is having an inquisitive look it seems a shame to void your warranty :-S

I'd like to know how do you benchmark those cards in Civ V. I suppose it's the in-game benchmark, isn't it? Well, I read some tests on one site using their own test recorded after some time spent in the game using FRAPS and I'm wondering if using the in-game test is that really different scenario. According to the source, in the real world situation nVidia cards' performance show no improvement whatsoever over AMD's offerings. If you could investigate that matter it would be great.
