Final Words

Traditionally dual-GPU cards have been a mixed bag. More often than not they have to sacrifice a significant amount of single-GPU performance in order to put two GPUs on a single card, and in the rare occasions where that tradeoff doesn’t happen there’s some other tradeoff such as a loud cooler or immense power consumption. NVIDIA told us that they could break this tradition and put two full GTX 680s on a single card, and that they could do that while making it quieter and less power consuming than a dual video card SLI setup. After going through our benchmarking process we can safely say that NVIDIA has met their goals.

From a gaming performance perspective we haven’t seen a dual-GPU card reach the performance of a pair of high-end cards in SLI/CF since the Radeon HD 4870X2 in 2008, so it’s quite refreshing to see someone get so close again 4 years later. The GTX 690 doesn’t quite reach the performance of the GTX 680 SLI, but it’s very, very close. Based on our benchmarks we’re looking at 95% of the performance of the GTX 680 SLI at 5760x1200 and 96% of the performance at 2560x1600. These are measurable differences, but only just. For all practical purposes the GTX 690 is a single card GTX 680 SLI – a single card GTX 680 SLI that consumes noticeably less power under load and is at least marginally quieter too.

With that said, this would typically be the part of the review where we would inject a well-placed recap of the potential downsides of multi-GPU technology; but in this case there’s really no need. Unlike the GTX 590 and unlike the GTX 295 NVIDIA is not making a performance tradeoff here compared to their single-GPU flagship card. When SLI works the GTX 690 is the fastest card out there, and when SLI doesn’t work the GTX 690 is still the fastest card out there. For the first time in a long time using a dual-GPU card doesn’t mean sacrificing single-GPU performance, and that’s a game changer.

At this point in time NVIDIA offers two different but compelling solutions for ultra-enthusiast performance; the GTX 690 and GTX 680 SLI, and they complement each other well. For most situations the GTX 690 is going to be the way to go thanks to its lower power consumption and lower noise levels, but for cases that need fully exhausting video cards the GTX 680 SLI can offer the same gaming performance at the same price. Unfortunately we’re going to have to put AMD out of the running here; as we’ve seen in games like Crysis and Metro the 7970 in Crossfire has a great deal of potential, but as it stands Crossfire is simply too broken overall to recommend.

The only real question I suppose is simply this: is the GTX 690 worthy of its $999 price tag? I don’t believe there’s any argument to be had with respect to whether the GTX 690 is worth getting over the GTX 680 SLI, as we’ve clearly answered that above. As a $999 card it doesn’t double the performance of the $499 GTX 680, but SLI has never offered quite that much of a performance boost. However at the same time SLI has almost always been good enough to justify the cost of another GPU if you must have performance better than what the fastest single GPU can provide, and this is one of those times.

Is $999 expensive? Absolutely. Is it worth it? If you’re gaming at 2560x1600 or 5760x1200, the GTX 690 is at least worth the consideration. You can certainly get by on less, but if you want 60fps or better and you want it with the same kind of ultra high quality single GPU cards can already deliver at 1920x1080, then you can’t do any better than the GTX 690.

Wrapping things up, there is one question left I feel like we still don’t have a good answer to: how much RAM a $999 card should have. NVIDIA went with a true equal for the GTX 680 SLI, right down to the 2GB of VRAM per GPU. Looking back at what happened to the Radeon HD 5970 and its 1GB of VRAM per GPU – we can’t even run our 5760x1200 benchmarks on it, let alone a couple of 2560x1600 benchmarks – I’m left uneasy. None of our benchmarks today seem to require more than 2GB of VRAM, but that much VRAM has been common in high-end cards since late 2010; the day will come when 2GB isn’t enough, and I'm left to wonder when. A GTX 690 with 4GB of VRAM per GPU would be practically future-proof, but with 2GB of VRAM NVIDIA is going to be cutting it close.

    Well, let's be fair... it's not nVidia's fault. It's TSMC that can't get their act together to produce 28nm chips in volume.

    The GTX680 has sold more card by the verified reviewers at NewEgg than the entire lot of the 7870's and 7850's at NewEgg combined, and that's just with ONE GTX680 sold by EVGA - check it out my friend...
    ROFL
    GTX680 in one listing outsells the entire lineup of 7870 and 7850 COMBINED at newegg- with verified owners count.
    HAHAHA
    Yes, the supply is always "key". ROFL

    I must confess that every logic i can think of says i don't need this GPU.....but.....i want it....i don't need it.....but damn it....i want it.....it's nvidia....it's aluminium....it's 4 GB VRAM....it's probably 5 times faster than what i have.......and i want to congratulate the team for the review wich i read from start to finish...but to be honest with you.....you don't need 19 pages to describe it...for me...."futureproof" says it all....

    Is there any way you can post the average FPS achieved during OCCT tests? Curious how 680 SLI, 690 and 7970 CF compare in this regard.
  • Ryan Smith - Thursday, May 3, 2012 - link

    Sorry, but we don't currently record that data (though if it's a big enough deal we can certainly start).

    Simply put, NVIDIA has superior software department in comparison with AMD.
    AMD is mainstream. Whenever they try to reach the high end, they fail miserably, both on GPU and CPU camps. Driver issues with crossfire, trifire and quadfire with or without eyefinity in numerous games (with eyefinity even more problems) etc.
    If they don't get their problems solved by Catalyst 12.5 buying AMD cards for high end builds (anything multicard related) is a waste of money. And that is sad.
  • CeriseCogburn - Thursday, May 3, 2012 - link

    Yes, and the reviewer is constantly trying to catch nVidia in a big lie - and it shows - he even states how he never believed a word nVidia said about this card but had to admit it was all true.
    I have never, in many years, seen the same bad attitude given to amd's gpu's.
    The bias in the write up is so blatant every time it's amazing they still get nVidia cards for review. The reviewer is clearly so pro amd he cannot hide it.
  • N4g4rok - Thursday, May 3, 2012 - link

    He did say that Crossfire was so broken that he couldn't recommend it. He's been pointing out flaws in both companies along the way I think you should dial back the bias accusations a little bit.
  • CeriseCogburn - Thursday, May 3, 2012 - link

    Well if you want me to point out like 10 blatant direct wordings in this article I will. I'm not the only one who sees it, by the way. you want to tell me how he avoids totally broken amd drivers when he's posting the 7970CF ? Not like he had a choice there, your point is absolutely worthless.

    Okay then, for our benefit (because we're stupid and that), please point out the reviewer's transgressions.
