NVIDIA GeForce GTX 680 Review: Retaking The Performance Crown
by Ryan Smith on March 22, 2012 9:00 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.
While Crysis was a strong game for the GTX 580, the same cannot be said of the GTX 680. NVIDIA is off to a very poor start here, with the Radeon HD 7970 easily outperforming the GTX 680, and even the 7950 is tied or nearly tied with the GTX 680 depending on the resolution. On the bright side the GTX 680 does manage to outperform the GTX 580, but only by a relatively meager 17%.
Given the large gap in theoretical performance between the GTX 680 and GTX 580, as it turns out we’ve run into one of the few scenarios where the GTX 680 doesn’t improve on the GTX 580: memory bandwidth. In our overclocking results we discovered that a core overclock had almost no impact on Crysis, whereas a memory overclock improved performance by 8%, almost exactly as much as the memory overclock itself. When it comes to the latest generation of cards it appears that Crysis loves memory bandwidth, and this is something the Radeon HD 7900 series has in spades but the GTX 680 does not. Thankfully for NVIDIA not every game is like Crysis.
The minimum framerate situation is even worse for NVIDIA here, with the GTX 680 clearly falling behind the 7950, and improving on the GTX 580 by only 10%. At its worst Crysis is absolutely devouring memory bandwidth here, and that leaves the GTX 680 underprepared.

Impressive combination of performance and power draw. AMD will have to adjust pricing.This looks promising for the lower end cards (which are of more interest to me). AMD's 77x0 cards have been somewhat disappointing, and I'll be looking forward to see what NVIDIA can offer in that price bracket and also the 78x0 competition.

With 28nm limited (in part because of the TSMC shutdown of the line) we won't see price reductions, the parts are going to be too limited for that to happen unfortunately, that is unless AMD stockpiled tons of chips before the TSMC shutdown. What we might see is AMD releasing drivers or new cards that stop underclocking their chips to keep the TDP so low. From what I've read in the reviews AMD has underclocked their cards significantly and could issue drivers tomorrow that boosts performance 30% but at the sacrifice of increased power consumption.The 680 appears to be a very nice card, but they tossed the compute performance out the window to accomplish it, the 580 smokes the 680 in most of the compute benchmarks. I find that disappointing personally and won't be upgrading as from my perspective it's not much of an upgrade against a 580. Shoot, show me a game that strains the 580, with every game produced a console port that is designed for DX9 I'm not sure why anyone bothers upgrading.

Ryan, why you did not include OC79XX as you did with OC GTX460 when 68XX were launched?Ryan Smith - Thursday, March 22, 2012 - link
Because you guys have made it abundantly clear that you don't want us doing that.http://www.anandtech.com/show/3988/the-use-of-evga...

"We were honestly afraid that if we didn't include at least a representative of the factory overclocked GTX 460s that we would get accused of being too favorable to AMD. As always, this is your site - you ultimately end up deciding how we do things around here. So I'm asking all of you to chime in with your thoughts - how would you like to handle these types of situations in the future?"Anand is asking what to do. The article form the link is not a proof of that. What are you talking about?

I think he's referring to the 620 comments worth of nerdrage more than the article.prophet001 - Thursday, March 22, 2012 - link
bad nerdrage is bad :(Janooo - Thursday, March 22, 2012 - link
I see.Still 680 overclocks/boosts on the fly and 7970 has set clock.
It's hard to compare them.

If you keep the 680 cool it goes faster - so a good way would be to crank the 680's fan to 100% and watch it further trounce the 7970, right ?Janooo - Thursday, March 22, 2012 - link
That's the thing. I am not sure 680 can clock higher than 7970. If we do the same for both cards 7970 might end up faster card.
