Introducing “the World’s Fastest Graphics card”, AMD’s flagship HD 6990
Unreal Tournament 3 (UT3)
Unreal Tournament 3 (UT3) is the fourth game in the Unreal Tournament series. UT3 is a first-person shooter and online multiplayer video game by Epic Games. Unreal Tournament 3 provides a good balance between image quality and performance, rendering complex scenes well even on lower-end PCs. Of course, on high-end graphics cards you can really turn up the detail. UT3 is primarily an online multiplayer title offering several game modes and it also includes an offline single-player game with a campaign. For our tests, we used the very latest game patch for Unreal Tournament 3. The game doesn’t have a built-in benchmarking tool, so we used FRAPS and did a fly-by of a chosen level. Here we note that performance numbers reported are a bit higher than compared to in-game. The map we use is called “Containment” and it is one of the most demanding of the fly-bys.
Our tests were run at resolutions of 2560 x 1600 and 1920 x 1200 with UT3’s in-game graphics options set to their maximum values. One drawback of the way the UT3 engine is designed is that there is no support for anti-aliasing built in. We forced 4xAA for 2560×1600 and 8xAA for 1920×1200 in each vendor’s control panel; 8xQ for Nvidia to match AMD Graphics’ 8xMSAA settings. We record a demo in the game and a set number of frames are saved in a file for playback. When playing back the demo, the game engine then renders the frames as quickly as possible, which is why you will often see it playing it back more quickly than you would actually play the game. Here is Containment Demo, first at 2560×1600 with 4xAA forced in each vendor’s control panel:
Now at 1920 x 1200 and with 8xAA (8xQ in Nvidia’s Control Panel) forced
There is absolutely no problem playing this game fully maxed-out with any of our graphics configurations. The HD 6990 hangs with the fastest Crossfired cards but falls to the fastest SLI’s configurations. Again, we do not see TriFire-X3 scale consistently. The HD 5870 catches and passes even the GTX 480 at 1920×1200 although the GTX 580 puts in the best showing at 2560×1600 and the GTX 570 and the GTX 480 trade blows with each other in a pretty even match up. The GTX 560 Ti has no trouble handling the HD 6870 and all SLI and CrossFired configurations give decent scaling beating the flagship video cards.
This is soooo intense, the scaling is near perfect and the price is somewhat reasonable. I’m still not sure about overclocking that thing, it’s already damn powerful 😛
I wonder how Nvidia will respond with their 590.
Good Job Poppin! *claps*
This is the holy grail of hd 6990 reviews!!!! All hail the king!!!!
Dang…that’s one IMBAH review right there.
Thanks for the epic review 😀 .
Thank-you all!
Let me make a big clarification. At the AMD presentation we were told that simply flipping the switch doesn’t violate the warranty.
That is technically correct. However *operating* the card in the 2nd OD position voids your warranty and makes what they told us at the meeting double-speak. If I had known this, I would have only tested it in the stock (warrantied) position.
WARNING: If you break the yellow sticker that covers the switch, you are NOT warrantied. However, each AMD Graphic Partner may have a different policy and I’d highly recommend that you get it in writing from them before you touch the switch if you are considering buying a HD 6990 (and care about overclocking and retaining your warranty).
I will update my article to make this very clear and to add another negative to the conclusion. All of my future testing will be done with this card in the non-overclocked (under warranty) position.
Hey apoppin, will there be a 11.4 driver review? I noticed that all other Radeon cards were tested with 11.2s and according to AMD there have been some improvements for the HD 6000 series with the new drivers.
Of course. As soon as WHQL 11.4 is released. 11.4 is a beta driver.
However, we did use 11.4 beta for the HD 6990 as it is the only release driver. And for comparison’s sake, we used our HD 6970 with 11.4 beta also – and also because we used it together with HD 6990 for TriFire-X3.
If you’d like to see the performance increase for HD 6970 with the new beta drivers, check out our 11.2 vs 11.1a Performance Analysis – we used the same settings as for the HD 6990 launch article:
http://alienbabeltech.com/main/?p=24120
You can see significant increases for HD 6970 with the new beta driver over the latest WHQL driver, 11.2. Probably there are also increases with the 6800 series.
We tested the rest of the AMD Graphics cards – except as noted above for HD 6990 and HD 6970 – with the latest WHQL driver as we usually do.
Thanks! Looking forward to it!
My spouse and i have been so thankful that Emmanuel managed to complete his studies through the entire precious recommendations he grabbed using your web page. It’s not at all simplistic to simply always be giving out tips which people today have been making money from. And now we fully understand we have the writer to appreciate for that. Those explanations you’ve made, the easy website navigation, the friendships you can make it easier to instill – it’s all impressive, and it’s really helping our son in addition to us consider that that situation is excellent, and that’s extraordinarily mandatory. Thank you for all the pieces!
