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…

    Yeah I don't get it either. The last review of the 6990 was fantastic with how it was color-coded. Now you have a DIRECT competitor in both price and performance and the 6990 is never highlighted in the charts!?!? It made it a real PITA to always go hunting for the 6990 bars when they should have been labeled from the get-go.

    Hopefully this can be remedied easily...

    Red/Green is horrible for those of us in this world that are colorblind. Blue/Green is equally horrible. I'd like to see textures used instead. Reply

    I've changed Ryan's colors. Green is for the stock and EVGA clocks, yellow is for OC 590, red for 6990, and orange for 6990 OC. For the color blind, I apologize but using green/red for the primary cards is pretty standard. Reply

    Common colorblindess is between Green/Red and Green/Blue. Red/Blue works great! Reply

    "After talking to several other reviewers, this does not seem to be an isolated case, and many of them have killed their cards with similar testing, which is far from being an extreme test."

    "I most strongly advise anyone to stay away from overclocking this product and use extremely conservative settings, maybe up to 650 MHz and no voltage adjustments."

    Looks like it is no OC champ.

    For high res action, H got their review up. 6990 even beats the 590 at Civ V. Conclusion is damning too:

    "We truly thought the GTX 590 was going to make the Radeon 6990 look bad, but the fact of the matter is that NVIDIA made the 6990 look that much better. The GTX 590 is not the "World's Fastest Single Card Solution" as stated on our page 1 slides; the Radeon HD 6990 is very much retaining that title. Hail to the King, baby! "

    2x 6950 on water looks to be my next buy. Must buy wider desk though :-)

    SweClockers also fried their card.. The blame nVidia quality drivers.

    Fanboy much? Anyone who is an AMD/ATi fanboy shouldn't be crowing about nVidia driver quality. That's one reason I left AMD and went full nVidia-only GPUs after a 4870 purchase. nVidia cards also play a lot nicer on Microsoft FSX, but not everyone cares about that just like not everyone cares about Civ5.

    ?? Fanboy? NVidia just released their highest end($700) card with a driver that fries it if you overvolt. Me commenting on that, how come that is fanboyism?

    It is nothing short of a disaster. Sweclockers fried 2(two) Gtx590's. Thats $1400 worth of hardware. TPU fried one.

    Sure I've had my share of driver issues with ATi, but not any more than with my 8800Gt. Couldn't care less whose name is printed on the sticker.

    "fries it if you overvolt."

    YOU overvolted it...not the drivers doing it automatically. Remember the saying "your mileage may vary" or "proceed at your own risk"?

    Yup. But who doesn't expect voltage tuning today? Read the back of the ASUS box: "50% faster with voltage tuning." Nice way to say: This card can't be oc'ed. It will catch fire. But of course, you are overvolting so it is your own fault.

    But, only reason I posted it was to warn ppl who invest $700 in a card and has it fry on them. I'm not arguing who shall take blame.

    Be careful, at least 6 cards dead, stay away from oc'ing it.
