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.

If you're going to keep your case open all day with your ear to the graphics card, then you might get that 70dB+, which won't be too nice on the ear. On the other hand you won't get much gaming done. :)I don't know the exact distance Anandtech measured this noise at, but Kitguru measured at about 1 metre and got 48dB when running Furmark, 40dB for normal load.

70dB is very low and only would apply if you are essentially living next to your computer - that's a 24-hour exposure level.NIOSH recommends 85dB as the upper limit for 8 hours of exposure, with a 3dB exchange rate - that is, every time you halve the amount of time you're exposed to the sound you can increase the volume by 3dB.

*ahem*"The document identifies a 24-hour exposure level of 70 decibels as the level of environmental noise which will *prevent* any measurable hearing loss over a lifetime"
does NOT say what the maximum is.
from my experience as an audio tech:
95dB is the start of temporary hearing loss, 110dB is the start of permanent and 140dB is the threshold of pain.
and for drunk people, they can't hear anything below 150dB :)

Both AMD and nVidia are out of mind, they are ignorant of the consequence by putting two gigantic chips with 5+billion transistors on the same board. I can't find the point of buying such outrageous card instead of building a CFX/SLI system. At least the latter isn't that loud, isn't that hot and consumes hardly more power than those monstrosities.TSMC is to blame. They dropped 32nm so it is impossible to get 6990/590 within 300W power envelope. But neither AMD nor nVidia turn back, but keep making these non-sense flagship cards.

What a shame it will be when next-generation 28nm Single GPU flagships wipe out these monsters with ease while consumes half the power, running silent.strikeback03 - Tuesday, March 8, 2011 - link
That hasn't traditionally happened. Look at the comparison between the 6990 and the 4870x2 - 2 generations, IIRC one process shrink. The 6990 does generally put up much better numbers, but consumes a lot more power to do so. Looking at a comparison between the 4870x2 and 5870 (double GPU on a larger process size to next-gen single-GPU) they are very close, with the 4870x2 overall holding a slight lead. And of course none of these high-end reference cards have ever been silent
