Back at CES 2011 EVGA showed off an interesting concept card featuring 2 GF104 GPUs on a single board. NVIDIA has long designed multi-GPU cards using their high-end GPUs to carve out a market segment above their top single-GPU cards, but while NVIDIA promotes SLI across almost the entire GeForce spectrum it’s promoted as a multi-card option for anything other than those halo cards. Over the years a handful of AMD and NVIDIA’s board partners have struck out on their own and designed their own multi-GPU boards, and at CES 2011 EVGA joined that club.

The resulting product was the EVGA GeForce GTX 460 2Win, which combined 2 overclocked GTX 460s onto a single board. Unfortunately for EVGA, NVIDIA launched the GTX 560 Ti and its associated GF114 GPU mere weeks after CES 2011. GF104 was (and still is) a very capable GPU, but at the end of the day GF114 allowed the GTX 560 Ti to offer a 30% performance improvement for only a very slight increase in power consumption. The GTX 460 2Win did well enough for EVGA to continue with the design, but like the GTX 460 itself, it was clear that the 2Win design was never going to reach its full potential with GF104.

So now in November of 2011 EVGA is back with their next 2Win card: the EVGA GeForce GTX 560 Ti 2Win. Having replaced the GF104 GPUs with GF114 and tweaked the board to handle the extra power consumption, EVGA is giving it another shot. And this time they’re gunning for NVIDIA’s flagship single-GPU card, the GTX 580. Their proposition? For only a little more than the GTX 580 they can offer 30% better performance.

EVGA advertises the GTX 560 Ti 2Win as a dual GTX 560 Ti card, and true to their word that’s what it is. It’s an important distinction to make between the 2Win and ultra high end mutli-GPU cards like the GTX 590 and Radeon HD 6990, as both of those are a best effort to squeeze two high-end GPUs into a single card while staying within a 375W power budget under normal operation. The end result is that NVIDIA and AMD have to heavily bin GPUs to find those that will perform at a suitably low voltage, and even then these cards aren’t clocked as high as the single-GPU behemoths they’re based on.

The 2Win on the other hand is exactly what it says on the label. Composed of 2 GF114 GPUs, the 2Win is a GTX 560 Ti SLI setup on a single card, with all of the specs and none of the compromises we see in ultra high end cards. In fact the 2Win is a factory overclocked card, if only slightly – its 850MHz core clock is a mild 3% higher than the 822MHz core clock of the baseline GTX 560 Ti, while the memory clock is identical at 1002MHz (4008MHz data rate). This is paired with 2GB of GDDR5, which is reduced to 1GB of effective VRAM due to the dual-GPU nature of the card.

When it comes to power consumption EVGA doesn’t officially specify a TDP for the 2Win, but given that it’s designed to be a true dual GTX 560 Ti its power requirements closely trend the GTX 560 Ti SLI. In this case that puts the load TDP around 340W, not accounting for any efficiencies gained from having 2 GPUs on a single card or the power consumption of a PCIe bridge chip. As a result this is fairly close to the GTX 590 and Radeon HD 6990, both of which are heavily binned to stay under 375W.

But the real story here of course is the performance for the price. We’ve seen the performance of the GTX 560 Ti SLI in the past, and the performance is quite remarkable. For some time now a pair of NVIDIA’s mid-tier video cards in SLI have been able to surpass a single high-end card, and this performance is the basis of the 2Win. EVGA promotes the 2Win as being more than 30% faster than the GTX 580 and this is something that’s easily achieved in games where SLI scales well.

At the same time the 2Win is priced close to the GTX 580 to further cement its competitive status. EVGA has put the MSRP of the 2Win at $519, which is anywhere between $50 more expensive than the very cheapest GTX 580 to roughly the same price as factory overclocked models. Ostensibly this makes the 2Win more expensive than the GTX 580, but not significantly so given that we’re talking about the high-end video card market. Overall this puts the 2Win in a very good position versus the GTX 580, so long as it can deliver on its 30% performance claims over the GTX 580.

Next to its performance against the GTX 580, the other uses EVGA are using to promote the 2Win are the benefits derived from having multiple GPUs on a single card: namely NVIDIA Surround support. As with the GTX 590, by having 2 GPUs on a single card EVGA can team together the display outputs on the GPUs to drive up to 4 displays, versus 2 displays on a single GPU. This gives the 2Win the ability to drive a triple monitor surround setup on its own, and with 2 GTX 560 Ti GPUs should have the horsepower to do so in most cases. 3D Vision Surround is also a viable possibility thanks to the 3 DL-DVI ports, but the performance hit from 3D Vision is likely more than the 2Win can handle.

Ultimately the 2Win’s status as a multi-GPU card composed of GTX 560 Tis puts it in a unique place. Next to the GTX 580, its only other meaningful competitors are the Radeon HD 6950 CF, and the regular GTX 560 Ti in SLI. The bad news for the 2Win is that these are both cheaper options than the 2Win – you’re paying a price premium to get it on a single card.

    - "On the other hand if you don’t share EVGA’s confidence in SLI, then very little has changed. If you believe that new games will have teething issues with SLI, that microstutter will continue to exist, and that not every game will scale well with SLI, then the 2Win is a poor choice in light of the more consistent performance of the GTX 580"

    What? Why not check frametimes in the games you benchmarks? It is easy, just enable the option in FRAPS and import the data in a spreadsheet. If high framerate comes in lumps, there is no perceived improvement.

    A focus on this will make SLI and Crossfire even better, please do that in your next review :)

    For now readers can check

    At this point it's not really a concern about our existing games. All of them are well developed on the driver side. The concern is with the future: will Batman microstutter? Will Serious Sam have SLI support with good scaling the day it launches? These are questions that can't be answered in the present, which is why it's largely a question of faith in NVIDIA's capabilities.
  • s44 - Monday, November 7, 2011 - link

    Is it possible to include a subjective microstutter report with these reviews?
  • dj christian - Thursday, November 10, 2011 - link

    Even though i am a long timereader of Anand since ten years back I really had to register to make this post..

    Actually Ryan i think you missed his point. Look at HardOCP:

    With diagrams you see exactly what drops and framespikes given over a period of time. It's so much clearer than showing simple staples which actually says nothing, especially at the highest resolutions which can be a bit tricky to get a grip on.

    For the next review of a graphic card i really hope you post diagrams along with the simple benchmarks which gives the reader a much bigger overview of such things.

    I know the first couple of pages of the article mention the redundancy of the SLI nub and the fact that this card needs an SLI-certified mobo, but I think these points should really rate a mention in the conclusion. Vram issues aside, for me these two failings almost completely invalidate this card as a useful option.

    I thought the point of dual-GPU cards was to allow:
    1. quad-SLI/quad-Xfire OR
    2. dual-GPU performance on less accommodating/feature-rich motherboards.

    The only viable application I can think of for this card (and I'm clutching at straws here) is on SLI-certified mATX boards in small enclosures where it is undesirable to use both slots for airflow reasons. Not sure I'd pay a 30% premium over 2 560 Ti boards for that.

    Good article, but readers who skim to the final page might be missing out on pertinent information.
  • Black1969ta - Monday, November 7, 2011 - link

    It requires an SLI Mobo, but can't be SLI'ed to another 560Ti 2WIN
    It pulls more power than 560Ti's in SLI.

    Excuses or not this review is pretty worthless without another 560Ti SLI boards to a dual GPU 560Ti Board.

    With the SLI Mobo certification requirement, and the lack of ability to add another 2WIN to get Quad GPU's with only two PCIe slots.

    And then Add in the $50+ Premium over 2 cards I fail to see the logic of this pricing and/or design.
    Without test results I fail to believe that I couldn't take two 560Ti Cards and SLI them with a modest OC and not get the same or better results.
  • Black1969ta - Monday, November 7, 2011 - link

    Ok I stand corrected, on the Game graphs I see the 560Ti SLI tested, but the 2WIN isn't $50 better which I suspected.

    FAIL EVGA!!!!!
  • Gonemad - Monday, November 7, 2011 - link

    I've always seen these dual-gpu cards as hit or miss, or more like an enthusiast part, really.

    If you just ignore the heat, the noise, the power consumption, then they become appealing, or even compete with 2 sli/cf cards.

    I still like powerful single-slot, single gpus cards better. No SLI issues, no CF issues, it just works, (or not). Should you ever need to upgrade, yay, you have a 2nd slot waiting, and hope you can still find your GPU for sale in compatible forms, then you go back in the SLI saddle.

    These cards compromise, one thing or another. Either you risk your PSU, or the builder has to tone down each gpu.

    I still would stick to a single 580, with the prospect in 1 year or 2, to buy a 2nd one, with a discount. I don't know, really.
  • s44 - Monday, November 7, 2011 - link

    Given that this is the most if not only significant PC-hardware-relevant release in years (pushes hardware while being critically popular *and* selling well), I hope you add it to the bench suite sooner rather than later.
  • Ryan Smith - Monday, November 7, 2011 - link

    The whole suite is getting redone for our SNB-E testbed.
