Civilization V
The other new game in our benchmark suite is Civilization 5, the latest incarnation in Firaxis Games’ series of turn-based strategy games. Civ 5 gives us an interesting look at things that not even RTSes can match, with a much weaker focus on shading in the game world, and a much greater focus on creating the geometry needed to bring such a world to life. In doing so it uses a slew of DirectX 11 technologies, including tessellation for said geometry and compute shaders for on-the-fly texture decompression.
In January we saw NVIDIA’s performance significantly improve in Civilization V. Since then AMD seems to have found their footing, albeit not as well as NVIDIA had. AMD’s primary gain here seems to be in CrossFire versus a boost in base performance, which works out well enough for the 6990’s launch. Interestingly Civ 5 is still so shader bound here on AMD’s cards that the 6990OC’s performance boost almost perfectly matches the increase in the core clockspeed. Still, at the end of the day the 6990 and the rest of the Radeons are still well outgunned by NVIDIA.

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.

I will be water cooling them! :)nitrousoxide - Tuesday, March 8, 2011 - link
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
