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.

    I never understood why they advertise 2GB, but the review says 1GB of useable memory. Can some one explain that to me?
  • Ryan Smith - Monday, November 7, 2011 - link

    With current multi-GPU technology (SLI and Crossfire), each GPU has its own copy of the working set of data and assets. Furthermore they can only work from their local VRAM, and they cannot (practically) work from the other GPU's VRAM.

    As a result you must duplicate the working set and assets across each GPU, which means you get half the effective VRAM.

    At the end of the day boardmakers can advertise having 2GB because it does in fact physically have 2GB, but logically it only has 1GB to work with.

    Thanks for clearing that up Ryan. So in any multil-gpu setup, the vram does not increase, unless the card itself has more of its own. Interesting limitation, so only compute power and bandwidth increase?

    It seems like it might make sense for nvidia to base their architecture on having 4, 8, or 16 GPU dies on every board. This would improve yield across the entire low/medium/high end due to smaller die sizes, and it would give a huge boost to the high end (assuming power limits are figured out). In today's age of supercomputers having 4000 chips per rack, it does not seem optimal to put just 1 or 2 per video card PCB.

    Great job, as usual; I have to agree with the conclusions made under "Final Thoughts". The only reason I'd go this route is if I needed the connectivity in terms of monitors and only had a single PCIe x16 slot on my mainboard. That being said, a 30% performance increase in your particular favorite game is nothing to ignore.

    One of the things I've been hoping is that EVGA would send Anandtech or Tomshardware (preferably both) a Classified card so one of these sites could run thorough overclocking tests on it. I highly doubt that the Classified could make up the 30% difference on air, but how much better than stock it can reach will be good to know before I buy.

    (It would also be interesting to know when AMD is going to release their next-gen GPU and whether or not it's going to be worth waiting a month or so for, but their recent CPU release puts them in the "I'm not holding my breath" category.)

    I went with this card and I'll tell you why


    I had two 560Ti's when I first built my pc, and having the sli bridge and the cards close together on a board, one card would be up at 65 to 70celcius under full load, and the other would be at 85 to 92!

    Anytime you have multiple graphics cards, the fans from the top card are pulling hot air directly from the other card's pcb backside.

    I had sold one of my 560s a while back for full price ($250) so instead of buy another one now, I sold the other for $200 and bought the 2Win. Now I only get up to 78celcius total. And once I change my case next week to a higher air flow case it will be even better.

    This is the best card I've ever had, better than two 6870s, a single gtx580 or even the 6990 I was using for mining. I have mine overclocked to 900Mhz and get another 10-12% increase in performance. Unbeatable as far as single cards go, especially considering the 6990 is $700 and the 590 is around that too
