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.

That's kind of disappointing.atticus14 - Thursday, December 22, 2011 - link
oh look its that guy that was banned from the forums for being an overboard nvidia zealot.medi01 - Tuesday, January 3, 2012 - link
Maybe he meant "somebody @ anandtech is again pissing on AMDs cookies"?I mean "oh, it's fastest and coolest single GPU card on the market, it is slightly more expensive than competitor's, but it kinda sucks since AMD didn't go "significantly cheaper than nVidia" route" is hard to call unbiased, eh?
Kind of disappointing conclusion, indeed.

To each their own but I think this is undeniable impressive:"Even with the same number of ROPs and a similar theoretical performance limit (29.6 vs 28.16), 7970 is pushing 51% more pixels than 6970 is" and
"it’s clear that AMD’s tessellation efficiency improvements are quite real, and that with Tahiti AMD can deliver much better tessellation performance than Cayman even at virtually the same theoretical triangle throughput rate."

I prefer nVidia products, mostly because the games I play (EA/DICE Battlefield-series) are heavily sponsered by nVidia, giving them a developement-edge.That out of the way, nVidia has had their problems just like this card is going to experience. Remember when Fermi came out, it was a performance joke, not because it was slow, but because it used a ridiculous amount of power to do the same thing as an ATI card while costing substantially more.
Fermi wasn't successful until second-generation products were released, most obviously the GTX460 and GT430, reasonably priced cards with quality drivers and low power consumption. But it took over a year for nVidia to release those, and it will take over a year for ATI to make this architecture shine.

Wat? The only thing there might be an issue with is drivers. As far as power consumption goes, this should be better than Cayman.CeriseCogburn - Sunday, March 11, 2012 - link
He's saying the 28mn node will have further power improvements. Take it as an amd compliment - rather you should have.StriderTR - Thursday, December 22, 2011 - link
EA/Dice are just as heavily sponsored by AMD, more in fact. Not sure where your getting your information, but its .. well ... wrong. Nvidia bought the rights to advertize the game with their hardware, AMD is heavily sponsoring BF3 and related material. Example, The Controller.Also, the GTX 580 and HD 6970 perform within a few FPS of each other on BF3. I run dual 6970's, by buddy runs dual 580's, we are almost always within 2 FPS of one and other at any given time.
AMD will have the new architecture "shining" in far under a year. They have been focused on it for a long time already.
Simple bottom line, both Nvidia and AMD make world class cards these days. No matter your preference, you have cards to choose from that will rock any games on the planet for a long time to come.

Umm, yea no. Not so much with nvidia and EA/DICE Batttlefield series giving nvidia a development edge. (if it does, the results are yet to be seen)Facts are facts, the 5 series to our current review today, the 7970, do and again continue to edge the Nvidia lines. The AMD Catalyst performance of particular note, BF3, has been far superior.

."..most obviously the GTX460 and GT430, reasonably priced cards with quality drivers and low power consumption. But it took over a year for nVidia to release those"GTX470/480 launched March 26, 2010
GTX460 launched July 12, 2010
GT430 launched October 11, 2010
Also, Fermi's performance at launch was not a joke. GTX470 delivered performance between HD5850 and HD5870, priced in the middle. Looking now, GTX480 ~ HD6970. So again, both of those cards did relatively well at the time. Once you consider overclocking of the 470/480, they did extremely well, both easily surprassing the 5870 in performance in overclocked states.
Sure power consumption was high, but that's the nature of the game for highest-end GPUs.
