AMD Radeon HD 7870 GHz Edition & Radeon HD 7850 Review: Rounding Out Southern Islands
by Ryan Smith on March 5, 2012 12:01 AM ESTCrysis: Warhead
Kicking things off as always is Crysis: Warhead. It’s no longer the toughest game in our benchmark suite, but it’s still a technically complex game that has proven to be a very consistent benchmark. Thus even four years since the release of the original Crysis, “but can it run Crysis?” is still an important question, and the answer continues to be “no.” While we’re closer than ever, full Enthusiast settings at a 60fps is still beyond the grasp of a single-GPU card.
As we’ll see throughout today’s benchmarks, Crysis ends up being a good proxy for the 7800 series’ performance, especially compared to the outgoing 6900 series. Ahead of the Southern Islands launch there was some doubt that AMD could deliver 6900 series performance with the 7800 series, and this doubt increased after the 7700 series underperformed the 6800 series. Results like what we're seeing with Crysis should make it clear that the 7800 series is more than a competitor for the 6900 series, with both the 7870 and 7850 equaling or beating the 6970 and 6950 respectively in almost all tests.
Overall at 1920x1200 the 7870 gets 39.9fps, which isn’t quite enough to smoothly handle enthusiast quality and 4x MSAA. Meanwhile the 7850 is farther down the line at 35.4fps; both cards would need Crysis’s settings turned down to reach 60fps here. Compared to the 7950 the 7870 trails it by 17%, giving AMD’s next card up a fairly wide lead in this game.
Meanwhile compared to NVIDIA’s lineup the 7800 series does quite well here, reflecting the fact that the 7800 series doesn’t have a true equal in NVIDIA’s existing lineup. At 1920 the 7870 leads the GTX 570 by 12% and is within spitting distance of the GTX 580, while the 7850 is virtually tied with the more expensive GTX 570 while it leads the GTX 560 Ti by 19%. Elsewhere at 2560 the 7870 has a similar lead, while the 7850 has a 41% lead on the GTX 560 Ti; while 2560 is not the ideal resolution for either card, it’s something to keep in mind when we begin discussing the impacts of the 7800’s 2GB of RAM.
When it comes to minimum framerates in Crysis the relative rankings are nearly identical. The 7800 series extends their lead over the 6900 series by a slight degree, while the lead over NVIDIA’s cards shrinks slightly.

Or don't. It's not on sale for 2 weeks yet.MySchizoBuddy - Monday, March 5, 2012 - link
NOT with 1/16 the FP64 performance.Zoomer - Wednesday, March 7, 2012 - link
FP64 is useless for games for the foreseeable future.CeriseCogburn - Thursday, March 8, 2012 - link
I love the "further image quality improvements page" which delicately and carefully explains how amd did a wonderful job of making things better as the image quality degrades...After noting the degredation very, very lightly and tossing out the problem, it is declared "unnoticable" for "all intents and purposes".
Eventually amd's IQ is going to be so far behind nvidia's the endless denials and it doesn't matters - will just continue since amd can crank an extra 20 fps doing it...
LOL
A "gift" from amd.

Article: " As AMD began winding down Cayman (6900 series) almost immediately with the launch of the 7900 series, at this point the 6900 market has effectively dried up. Having taken themselves out of competition with themselves, AMD’s only competition is NVIDIA’s lineup."--
And there we have it - AMD and their evil plot to squeeze every last dollar out of those "they care about", the gamers...
I don't want to hear Nvidia is evil anymore.
Time to look in the mirror amd users.

Furthermore, it's time the reviewers start slamming AMD the way they slam Nvidia, in this case, one can consider it PRAISE for AMD "drying up their own card channels"- and if that isn't bias I don't know what is.

These cards don't seem like such a wonderful value considering what the 6900 series was offering, but since those cards have gone poof, I guess you'll have to settle for the 7800 series? It really just seems like they are adjusting their pricing scheme to be less compressed than it was before.TL: DR; If you've got a 6900 series card, the 7000 series is not for you.

I still have my wonderful 5870 I purchased in 2009 (which now is not far from 3 years ago...), and still waiting for something that offers more performance than the 7970. Com'on Nvidia! Blow everything out of the water please....Death666Angel - Monday, March 5, 2012 - link
"TL: DR; If you've got a 6900 series card, the 7000 series is not for you."I'd say the 30 to 50% increase of the 79xx to 69xx cards could be well worth it. However, unless you run a multi-monitor setup or have a 2560 resolution, you really should think twice about spending that amount of money on these cards. But I guess people with that kind of cash can either do their own thinking or don't have to care too much about spending and can afford to "BUY ALL THE CARDS".
I'm still running a HD5770 and have a newly acquired 27" monitor here that is really stressing it. I think I'll go for a 78xx and later upgrade to CF because my 550W PSU can handle it with these cards, whereas HD69xx would be stressing it too much. :-)

"TL: DR; If you've got a 6900 series card, the 7000 series is not for you."Thats the dumbest statement I have ever read here. The 7970 is DOUBLE the performance of the 6970 with overclocking. Even the $250 7850 beats the 6970 with overclocking.
The 7 series is the biggest performance jump over the previous series since I have followed graphics cards, since 1998.
