Metro 2033
The next game on our list is 4A Games’ Metro 2033, their tunnel shooter released last year. In September the game finally received a major patch resolving some outstanding image quality issues with the game, finally making it suitable for use in our benchmark suite. At the same time a dedicated benchmark mode was added to the game, giving us the ability to reliably benchmark much more stressful situations than we could with FRAPS. If Crysis is a tropical GPU killer, then Metro would be its underground counterpart.
Being a particularly shader heavy game, Metro is one of the better games for both the 6990 and the Radeon 6900 series in general. At 2560 it’s within 5% of the GTX 580 SLI, and compared to the 5970 the 6990 has a 24% performance advantage.

Nice, but what about the Radeon HD 6450, 6570 and 6670?http://en.wikipedia.org/wiki/Comparison_of_ATI_Gra...
Why they are available for OEM only? They looks interesting, especially the 6670, which with its 480 SP should be faster than the 5670 which has 400 SP and lower frequency. Do you plan to review them?

As you note, they're OEM only. AMD will release them to the retail market eventually, but clearly they're not in a hurry. It's unlikely we'll review them until then, as OEM cards are difficult to come by.misfit410 - Tuesday, March 8, 2011 - link
I have to ask, if you bring up the price and say that you might as well do two 6950's in SLI when this thing doubles the performance of the GTX580, I mean would it also not be the better solution than a GTX580 which is $500 while two 6950's can apparently double it for $550 being they can be found for $225 after rebates these days.Figaro56 - Tuesday, March 8, 2011 - link
You sound a little confused. You can't run ATI cards in SLI, they run in what is called crossfire (or crossfirex which is the same thing). Two 6950's don't equal GTX580 in SLI. You need two HD 6970 cards in crossfire to nearly equal two GTX580 in SLI.In my opinion, why limit your performance with 2 HD 6950 cards, why not just bye the 2 HD 6970 cards and never have to second guess if you should have or not? But... That's just me. I have a job.

Totally unnecessary closing comment there, considering most people here do actually have jobs. Not everyone who has a job can afford such gear as there's more important things to spend money on.Thanny - Tuesday, March 8, 2011 - link
You sound confused, too. He miswrote SLI, but you misunderstood his point entirely. He's saying that two 6950's are significantly faster than a single 580 for almost the same price.Loiosh - Tuesday, March 8, 2011 - link
Hey guys, you forgot one other usage case that would necessitate this card: ATI+physx setup: http://www.shackpics.com/viewer.x?file=DumbVideoca...I'm currently running one and it requires a dual-GPU card. :/
In my case I'm waiting for a watercooled version. BTW, you didn't say the release date for this?

Funny after reading this review I went into town (Tokyo) to buy a new hard disk and saw this card for sale. So in Japan at least it is already on the market..... price was ridiculous though, 79,000YEN or $945 US..... I'm sure it will be available everywhere soon.Waterblocks on the other hand could be a couple month or so away I guess...

If you buy this you better have it on water. 'nuff said about all this tri slot cooler talk.JPForums - Tuesday, March 8, 2011 - link
First off, nice article Ryan.Good data, relevant commentaries on said data, and conclusions.
You mention in the article that you believe some of the shortcomings of the 6990 to be a lack of PCIe bandwidth. This got me thinking that perhaps it is a good time to revisit the effect of PCIe bandwidth on modern cards. Given the P67 only natively supports 16 lanes, I'm curious to see what effect it has on CF/SLI. It could make big difference in the recommended hardware for various levels of gaming systems.
Typically, someone looking for a CF/SLI setup will get a board that supports more lanes. However, I have seen a situation where a friend built a budget i5 system and about 4 months later was in a position to acquire an HD5970 on the cheap (relatively speaking). Clearly, two HD5850s/HD5870s would have been an option.
If newer cards are effectively PCIe bandwidth limited, then a 6990 may perform more closely to an HD6970 CF setup in such a system than it does in these graphs. This would be even more of a consideration at the high end if the rare boards with support for 4x8 lane (spaced) PCIe give you no real benefit over a more common 2x16 lane board (comparing 4 HD6970s to 2 HD6990s).
