Final Thoughts

If my final thoughts start sounding like a broken record, it’s because once again a set of NVIDIA & AMD product launches have resulted in a pair of similarly performing products.

The crux of the matter is that NVIDIA and AMD have significantly different architectures, and once again this has resulted in cards that are quite equal on average but are all over the place in individual games and applications. If we just look at the mean performance lead/loss for all games at 2560, the GTX 590 is within 1% of the 6990; however, within those games there’s a great deal of variance. The GTX 590 does extremely well in Civilization V as we’d expect, along with DIRT 2, Mass Effect 2, and HAWX. Meanwhile in Crysis, BattleForge, and especially STALKER the GTX 590 comes up very short. Thus choosing the most appropriate card is heavily reliant what games are going to be played on it, and as a result there is no one card that can be crowned king.

Of the games NVIDIA does well in, only Civ5 is a game we’d classify as highly demanding; the rest are games where the GTX 590 is winning, but it’s also getting 100+ frames per second. Meanwhile on the games AMD does well at the average framerate is much lower, and all of the games are what we’d consider demanding. Past performance does not perfectly predict future performance, but there’s a good chance the 6990 is going to have a similar lead on future, similarly intensive games (at least as long as extreme tessellation isn’t a factor). So if you had to choose a card based on planning for future use as opposed to current games, the 6990 is probably the better choice from a performance perspective. Otherwise if you’re choosing based off of games you’d play today, you need to look at the individual games.

With that said, the wildcard right now is noise. Dual-GPU cards are loud, but the GTX 590 ends up being the quieter of the two by quite a bit; the poor showing of the 6990 ends up making the GTX 590 look a lot more reasonable than it necessarily is. The situation is a lot like the launch of the GTX 480, where we saw the GTX 480 take the performance crown, but at the cost of noise. The 6990’s performance advantage in shader-intensive games goes hand-in-hand with a much louder fan; whether this is a suitable tradeoff is going to be up to you to decide.

Ultimately we’re still looking at niche products here, so we shouldn’t lose sight of that fact. A pair of single-GPU cards in SLI/CF is still going to be faster and a bit quieter if not a bit more power hungry, all for the same price or less. The GTX 590 corrects the 6990’s biggest disadvantage versus a pair of single-GPU cards, but it ends up being no faster on average than a pair of $280 6950s, and slower than a pair of $350 GTX 570s. At the end of the day the only thing really threatened here is the GTX 580 SLI; while it’s bar none the fastest dual-GPU setup there is, at $1000 for a pair of the cards a quad-GPU setup is only another $400. For everything else, as was the case with the Radeon HD 6990, it’s a matter of deciding whether you want two video cards on one PCB or two PCBs.

Quickly, let's also touch upon factory overclocked/premium cards, since we had the chance to look at one today with the EVGA GeForce GTX 590 Classified. EVGA’s factory overclock isn’t anything special, and indeed if it were much less it wouldn’t even be worth the time to benchmark. Still, EVGA is charging 4% more for about as much of a performance increase, and then is coupling that with a lifetime warranty; ignore the pack-in items and you have your usual EVGA value-added fare, and all told it’s a reasonable deal, particularly when most other GTX 590s don’t come with that kind of warranty. Meanwhile EVGA’s overclocking utility suite is nice to see as always, though with the changes to OCP (and the inability to see when it kicks in) I’m not convinced GTX 590 is a great choice for end-user overclocking right now.

Update: April 2nd, 2011: Starting with the 267.91 drivers and release 270 drivers, NVIDIA has disabled overvolting on the GTX 590 entirely. This is likely a consequence of several highly-publicized incidents where GTX 590 cards died as a result of overvolting. Although it's unusual to see a card designed to not be overclockable, clearly this is where NVIDIA intends to be.

Finally, there’s still the multi-monitor situation to look at. We’ve only touched on a single monitor at 2560; with Eyefinity and NVIDIA/3D Vision Surround things can certainly change, particularly with the 6990’s extra 512MB of RAM per GPU to better handle higher resolutions. But that is a story for another day, so for that you will have to stay tuned…

    Ryan, I commented last week on the 550 review. Just to echo that comment here: how are you getting the "nodes per day" numbers? Have you considered switching to a points per day metric? Very few people can explain what nodes per day are, and they aren't a very good measure for real world folding performance.

    (also, it seems like you should double the number for this review, since I'm guessing it was just ignoring the second GPU)

    Last year NVIDIA worked with the F@H group to provide a special version of the client for benchmark purposes. Nodes per day is how the client reports its results. Since points are arbitrary based on how the F@H group is scoring things, I can't really make a conversion. Reply

    Good to see that a $700 finally has a decent cooler! Why would somebody spend $700 & then go and hafta spend another $40 for an aftermarket cooler??? nvidia & AMD really need to just charge $750 and hve an ultra quiet card, these people in this price range are'nt gonna squabble over an extra $50 for petes sake!!!! it makes no sense that they skimp on the cooler at this price range! this is the top of the line where money isnt the issue!

    Let's get this straight, nVidia. Slapping two of your existing GPUs together does not make this a "next-generation card". Saying that you've been working on it for two years is also misleading; I doubt it took two years just to lay out the PCB to get two GPUs on a single board.

    SLI and Crossfire still feel like kludges. Take Crysis 2 for example. The game comes out, and I try to play it on my 295. It runs, but only on one GPU. So I go looking online; it turns out that there's an SLI profile update for the game, but only for the latest beta drivers. If you install those drivers *and* the profile update, you'll get the speed boost, but also various graphical corruption issues involving flickering of certain types of effects (that seem universal rather than isolated).

    After two goes at SLI (first dual 285s, next a 295), I've come to the conclusion that SLI is just not worth the headache. You'll end up dealing with constant compatibility issues.

    And that is why people still buy the 6970/580, rather than having 2 cheaper cards in SLI like so many recommend. Reply

    For the record, I've had three goes at CrossFire (2 x 3870, 4870X2, and now 2 x 5850). I'm equally disappointed with day-of-release gaming results. But, if you stick to titles that are 2-3 months old, it's a lot better. (Yeah, spend $600 on GPUs just so you can wait two months after a game release before buying....) Reply

    I don't know about that, the original Crysis still has a lot of issues with SLI. Reply

    "For the GTX 590 launch, NVIDIA once again sampled partner cards rather than sampling reference cards directly to the press. Even with this, all of the cards launching today are more-or-less reference with a few cosmetic changes, so everything we’re describing here applies to all other GTX 590 cards unless otherwise noted.

    With that out of the way, the card we were sampled is the EVGA GeForce GTX 590 Classified, a premium GTX 590 offering from EVGA. The important difference from the reference GTX 590 is that GTX 590 Classified ships at slightly higher clocks—630/864 vs. 607/853.5—and comes with a premium package, which we will get into later. The GTX 590 Classified also commands a premium price of $729."

    Are we calling overclocked cards "more-or-less reference" cards now? That's a nice way to put it, I'll use it the next time I get stopped by a police officer. Sir, I was going more or less 100mph.

    Reference is ONE THING. It is the basis and does not waver. Anything that is not it is either overclocked or underclocked.

    Bad example, as in the US at least your speedometer is only required to be accurate within 10%, meaning you can't get ticketed at less than 10% over the speed limit. This card is only overclocked by 4%. More importantly, they a) weren't sent a reference card, and b) included full tests at stock clocks. Would you rather they not review it since it isn't a reference card? Reply
  • Nentor - Thursday, March 24, 2011 - link

    That is a good point actually, I didn't think of that.

    Maybe reject the card yes, but that is not going to happen. Nvidia is just showing who is boss by sending a non reference card. AT will have to swallow whatever Nvidia feeds them if they want to keep bringing the news.
