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

The launch drivers for the 6990 will be a preview version of Catalyst 11.4, which have been made available today and the final version launching sometime in April. Compared to the earlier drivers we’ve been using performance in most of our games is up by at least a few percent, particularly in CrossFire. For launching a dual-GPU card like the 6990, the timing couldn’t be better.
Along with these performance improvements AMD is also throwing a few new features in to the Catalyst Control Center, making it the first time they’ve touched it since the introduction of the new design in January. Chief among these features – and also timed to launch with the 6990 today - is 5x1 portrait Eyefinity mode. Previously AMD has supported 3x1 and 3x2, but never anything wider than 3 monitors (even on the Eyefinity 6 series).
The 6990 is of course perfectly suited for the task as it's able to drive 4 + 1 monitors without any miniDP MST hubs, and indeed the rendering capabilities of this card are wasted a good deal of the time only driving one monitor. Other cards will also support 5x1P, but only E6 cards can work without a MST hub at the moment. Notably, in spite of requiring one fewer monitor than 3x2 Eyefinity this is easily the most expensive option for Eyefinty yet, as portrait modes require monitors with wide vertical viewing angles to avoid color washout – you’d be hard pressed to build a suitable setup with cheap TN monitors like you can the landscape modes.
The other big change for power users is that AMD is adding a software update feature to the Catalyst Control Center, which will allow users to check for driver updates from within the CCC. It will also have an automatic update feature, which will check for driver updates every 2 weeks. At this point there seems to be some confusion over at AMD over whether this will be enabled by default or not – our drivers have it enabled by default, while we were initially told it would be disabled. From AMD’s perspective having the auto update feature enabled improves the user experience by helping to get users on newer drivers that resolve bugs in similarly new games, but at the same time I could easily see this backfiring with users by being one more piece of software nagging for an update every month.
Finally, AMD is undergoing a rebranding (again), this time for the Catalyst Control Center. If you use an AMD CPU + AMD consumer GPU, the Catalyst Control Center is now the AMD VISION Engine Control Center. If you use an Intel CPU + AMD consumer GPU it’s still the Catalyst Control Center. If you use a professional GPU (regardless of CPU), it’s the Catalyst Pro Control Center.
The Test
Due to the timing of this launch we haven’t had an opportunity to do in-depth testing of Eyefinity configurations. We will be updating this article with Eyefinity performance data in the next day. In the meantime we have our usual collection of single monitor tests.

Just be prepared to upgrade your GPU every year. If you think they are going to stop leap frogging performance you are not being realistic.san1s - Tuesday, March 8, 2011 - link
"AMD even went so far as to suggest that reviewers not directly disassemble their 6990"The next picture: The card disassembled
haha

To AMD's credit, they were good sports offered to take any pictures we needed. So all of those disassembled shots came from them. They were really adamant about it being a bad idea to take these things apart if you intended to use them in the future.strikeback03 - Tuesday, March 8, 2011 - link
I was looking for a comment on whether you did all your testing before disassembling or whether you got some of their super paste to reassemble.7Enigma - Tuesday, March 8, 2011 - link
My problem with the shot is the poor application of thermal paste from the picture. In a card of this magnitude having a perfect coating of thermal compound is critical. And knowing marketing if that is the shot they SHOW, how good do you really think the application is on one purchased in retail channels?iwod - Tuesday, March 8, 2011 - link
I haven't been following CrossFire / SLI or these Single Card Dual GPU closely. ( Which to me are the same as two card anyway )Do they still need drivers to have a specific profile of the game to take advantage? I.e an Unknown Game to the Drivers will gain 0 benefits from the 2nd GPU?
If that is so, then they are not even worth a look.

Most of the big games support SLI and CrossfireX today. For example, I play Battlefield BC2 myself and using 2 video cards blows the doors of a single card and is well worth the investment, especially if you have a 2560x1600 resolution monitor like I do. For 2 ATI cards in Crossfire you install a separate crossfire profiles pack in addition to the catalyst drivers. The profiles pack supports all the game crossfire optimization. The AI mode in the catalyst drivers exploits the game profile pack setting for crossfire so you want that enabled.A dual GPU HD 6990 is essentially crossfire on a single card, but for some reason it doesn't perform as well as dual single GPU cards in crossfire. Go figure.
If you play old games that don't support SLI or Crossfire then YES there is 0 gain. If you have not tried any of the new games what are you waiting for? It doesn't suck you know?!

I agree, unless you have eyefinity and one slot, paying a premium for heat and noise doesnt make sense. For most people with 1 screen a 6970 or 580 is more than enough.Samus - Tuesday, March 8, 2011 - link
i'd be shocked if they sold even one of these without it being returned at some point. the noise levels are astonishing. at full blast the thing doesn't even meet federal vehicle emissions noise regulations without being classified as a motorcycle!MadAd - Tuesday, March 8, 2011 - link
8%? where do we buy tubes of this phase change material? do they sell it like arctic silver?
