Metro: 2033
Paired with Crysis as our second behemoth FPS is Metro: 2033. Metro gives up Crysis’ lush tropics and frozen wastelands for an underground experience, but even underground it can be quite brutal on GPUs, which is why it’s also our new benchmark of choice for looking at power/temperature/noise during a game. If its sequel due this year is anywhere near as GPU intensive then a single GPU may not be enough to run the game with every quality feature turned up.
As often as we concern ourselves with Crysis and 60fps, with Metro it’s a struggle just to break 30fps. The 7970 becomes the first video card that can accomplish this at 2560 though it’s going to need quite a bit more performance to run Metro fluidly from start to end.
Compared to the GTX 580 the 7970’s lead in Metro is similar, but the scaling with resolution is even more pronounced. At 2560 it’s ahead by 30%, while at 1920 this drops to 21%, and finally at 1680 it’s only 16%. Meanwhile compared to the 6970 the response is much flatter; 33% at 2560, 28% at 1920, and 27% at 1680. From this data it’s becoming increasingly evident that the value proposition of the 7970 is going to hinge on not only what you consider its competitors to be, but what resolutions you would use it at.
While we’re on the subject of Metro, this is a good time to bring up the performance of the 5870, the forerunner of the DX11 generation. The performance of the 7970 may only be 20-30% higher than its immediate predecessors, but that’s not to say that performance hasn’t increased a great deal more over the full 2 year period of the 40nm cycle. The 7970 leads the 5870 by 50-60% here and in a number of other games, and while this isn’t as great as some past leaps it’s clear that there’s still plenty of growth in GPU performance occurring.

Lol, how's that, when I'm the one saying that AMD's cards are the best performers in Crysis 2?I'm neutral, a concept that is obviously alien to you. Idiots...

Heck, I'm also the guy who made Endless City run on non-nVidia cards. How does that make me an nVidia fanboy?CeriseCogburn - Thursday, March 8, 2012 - link
That's sad when an nvidia fanboy has to help all the amd fannies with software coding so they can run a benchmark, then after all that work to help the underprivileged, nothing but attacks after the facts... finally silence them.It's really sad when the truth is so far from the pop culture mind that actually speaking it is nearly forbidden.
Thank you for helping them with the benchmark. Continue to be kind in such ways to the sour whining and disgruntled, as it only helped prove how pathetic amd dx11 was...

This sounded like such an awesome card and I was psyched to get it the moment it comes out -- until reading the part about dropping the 2nd DVI port. A DisplayPort-to-SLDVI doesn't do it, for me, because my desktop has to drive two 30" displays. In fact, I would love to be able to drive a third display so I can have a touch-screen also. My current (previous-generation) VDC does drive both displays just fine.This does not seem like such an infrequent requirement, especially for high-end users. Why would they drop the ability to drive the 2nd display? !!!
Argh!

not trying to sell you anything but, HDMI to dual-link dvi does exist (see link, or google yourself for other shops).http://sewelldirect.com/hdmi-to-dvi-dual-link-cabl...
and these cards do have 1 HDMI-out so that should work for you.

It's the IHV that makes those decisions any way, just because it's not on a reference card doesn't mean they won't show up or that you can't build a card with it. But the HDMI supports more then 1920x1200 finally on this card any how. I guess they could deliver a card with the old type of DVI>HDMI adapters. Obviously opting for HDMI and multidisplaycapable displayport 1.2 makes more sense though. It's been around for years now.Penti - Wednesday, January 4, 2012 - link
Just make sure you actually has the number of connections you need when buying the card, many 7970 bords only appear to support single-link DVI on the DVI-connector.poordirtfarmer2 - Wednesday, January 4, 2012 - link
Enjoyed the article.So this new 79XX architecture is about a GPU architecture that’s also good for “compute work”. The reference to NVIDIA ‘s professional video cards (Quadro ; Telsa), implies to me that this might mean video cards viable for use both in gaming and in engineering / video work stations.
I’m not a pro, but do a lot of video editing, rendering and encoding. I’ve avoided dedicating a machine with an expensive special purpose QUADRO video card. Am I reading the wrong thing into this review, or might the new 79XX and the right driver give folks like me the best of both worlds?

UVD 3 in NextGen is a disappointing. Nvidia is two generation in front with PureVideo HD 5.psiboy - Monday, January 9, 2012 - link
Well Mr Ryan Smith I must ask why the omission of 1920 x 1080 in al lbenchmarks... given that almost every new monitor for quite some time has been natively 1920 x 1080... what is it with you guys and Tom's lately.. you both seem to have been ignoring the reality of what most of your readers are using!
