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…

    First paragraph:

    "It really doesn’t seem like it’s been all that long, but it’s been nearly a year and a half since NVIDIA has had a dual-GPU card on the market. The GeForce GTX 295 was launched in January of 2009, the first card based on the 55nm die shrink of the GT200 GPU."

    Well, shit. I thought Jan 2009 was TWO and a half years ago. I MUST GET BACK TO THE FUTURE!

    It was on the market after its launch. so if it disappeared somewhere at the end of 09/beginning of 10 that would match the "year and a half since on the market" Reply

    Are there any reviews with such a setup out yet, or is it even supported? Maybe even a 3x or 4x setup? If it was a 4x 6990 setup or 590 setup could it rule the world? Reply

    You can't go over 4 GPUs, so you can only SLI/CF two of the dual GPU cards. Reply

    I'll be going with two 570's for the same price, thanks. And I can spread that pain at $350 per purchase over two months instead of one big $700 plunkdown. Reply

    "....However the noise results are nothing short of remarkable – if NVIDIA can dissipate 350W+ of heat while at the same time making 5-7dB less noise, then it starts to become clear that AMD’s design has a serious weakness. The ultimate question is what did NVIDIA do right that AMD did not?...."

    I can't see anyone tolerating the noise level of the 6990. But the 590 is barely noisier than a 580. So an easy win for nVidia if you really need/can afford one of these monsters.

    Ya, even the 6970/6950 are hot cards. Very disappointing after a very cool and silent 5870. I think AMD had a problem with the chips and never intended for them to be so hot. Maybe they had to crank up the power to get them to run right? idk........... Reply

    This card might be good for those people out there who love to cram as many GPUs into one box as they can and run folding at home. Reply

    Major bias with the OC listing in the charts... the OC version is not enough... but a 20+% OC is included versus the other standard configs... and the lousy flip switch OC mode of 6990... not around 940/1400+ that other sites have attained.... that offers 6970CF+ performance :s ...Why dont they show 5870/6950/6970 CF & 470/480/570/580 SLI etc with appropriate 20%+ overclocks to put these cards in their place... especially with price vs performance.... the 2gb 6950s also having the ability to be flashed into 6970s too... not bad CF for price...

    The second fastest single card out there.... but still a beast and its kept its idle power within reason... i think its time for 28nm tech asap... as the carbon taxes on these bad boys will be horrendous...lol

    When you do the 3x monitor review can you please include last generations top end card (5970) for comparisons. Eyefinity and co is really where it is at with this monster graphics cards and in my experience the 5970 just doesn't have the horse power to play well at 5760x1200. I would really like to see how much difference these new cards and their increased RAM actually makes.

    50% performance compared to last generation at 2560 is OK, but do they get even more distance with the higher resolution?
