Final Words

Bringing this review to a close, when I first heard that AMD was going to build a full performance dual Hawaii GPU solution, I was admittedly unsure about what to expect. The power requirements for a dual Hawaii card would pose an interesting set of challenges for AMD, and AMD’s most recent high-end air coolers were not as effective as they should have been.

In that context AMD’s decision to build a card around a closed loop liquid cooling solution makes a lot of sense for what they wanted to achieve. Like any uncommon cooling solution, the semi-exotic nature of a CLLC is a double edged sword that brings with it both benefits and drawbacks; the benefits being enhanced cooling performance, and the drawbacks being complexity and size. So it was clear from the start that given AMD’s goals and their chips, the benefits they could stand to gain could very well outweigh the drawbacks of going so far off of the beaten path.

To that end the Radeon R9 295X2 is a beast, and that goes for every sense of the word. From a performance standpoint AMD has delivered on their goals of offering the full, unthrottled performance of a Radeon R9 290X Crossfire solution. AMD has called the 295X2 an “uncompromised” card and that’s exactly what they have put together, making absolutely no performance compromises in putting a pair of Hawaii GPUs on to a single video card. In a sense it’s almost too simple – there are no real edge cases or other performance bottlenecks to discuss – but then again that’s exactly what it means to offer uncompromised performance.

“Beastly” is just as fitting for the card when it comes to its cooling too. With a maximum noise level of 50dB the 295X2’s CLLC is unlike anything we’re reviewed before, offering acoustic performance as good as or better than some of the best high end cards of this generation despite the heavy cooling workloads such a product calls for. Which brings us to the other beastly aspect, which is the card’s 500W TDP. AMD has put together a card that can put out 500W of heat and still keep itself cooled, but there’s no getting around the fact that at half a kilowatt in power consumption the 295X2 draws more power than any other single card we’ve reviewed before.

Taken altogether this puts the 295X2 in a very interesting spot. The performance offered by the 295X2 is the same performance offered by the 290X in Crossfire, no more and no less. This means that depending on whether we’re looking at 2K or 4K resolutions the 295X2 either trails a cheaper set of GTX 780 Tis in SLI by 5%, or at the kinds of resolutions that most require this much performance it can now exceed those very same GeForce cards by 5%. On the other hand NVIDIA still holds a consistent edge over AMD in frame pacing. But thanks to their XDMA engine AMD's frame pacing performance is vastly improved compared to their prior dual-GPU cards and is now good enough overall (though there's definitely room for further improvement).

But more significantly, by its very nature as a CLLC equipped dual-GPU video card the 295X2 stands alone among current video cards. There’s nothing else like it in terms of design, and that admittedly makes it difficult to properly place the 295X2 in reference to other video cards. Do we talk about how it’s one of only a handful of dual-GPU cards? Or do we talk about the price? Or do we talk about the unconventional cooler?

However perhaps it’s best to frame the 295X2 with respect to its competition, or rather the lack thereof. For all the benefits and drawbacks of AMD’s card perhaps the most unexpected thing they have going for them is that they won’t be facing any real competition from NVIDIA. NVIDIA has announced their own dual-GPU card for later this month, the GeForce GTX Titan Z, but priced at $3000 and targeted more heavily at compute users than it is gamers, the GTX Titan Z is going to reside in its own little niche, leaving the 295X2 alone in the market at half the price. We’ll see what GTX Titan Z brings to the table later this month, but no matter what AMD is going to have an incredible edge on price that we expect will make most potential buyers think twice, despite the 295X2’s own $1500 price tag.

Ultimately while this outcome does put the 295X2 in something of a “winner by default” position, it does not change the fact that AMD has put together a very solid card, and what’s by far their best dual-GPU card yet. Between the price tag and the unconventional cooler it’s certainly a departure from the norm, but for those buyers who can afford and fit this beastly card, it sets a new and very high standard for just what a dual-GPU should do.

    Well, Arctic's 6990 cooler wasn't far off. The arctic mono is good for 300W and it should be possible to fit two such heatsinks on one card. So it's possible. The resulting card would be absolutely huge though, and wouldn't be nearly as popular with gaming PC boutiques (IE the target market).

    Oh, VRM cooling might be an issue too. I guess a thermaltake-style heatpipe arrangement would fix that.

    Huh looking at that board and layout of the cooling setup you can swap in two independent closed looped coolers pretty easily and try and overclock it if you want and since your rich if you buy this it's totally viable for any owner

    Ryan, thank you for a wonderfully written and informative review. Appreciate much.

    Ryan Smith , Please Confirm this :

    The new nv's Driver Does Overclock GTX 780 Ti, From 928 to 1019Mhz.if So Temp should be increased.

    and also Power Consumption
  • Ryan Smith - Tuesday, April 8, 2014 - link

    Overclock GTX 780 Ti? No. I did not see any changes in clockspeeds or temperatures that I can recall.

    I have a Antec Signature 850W sitting in the closet. 295X2 too much for it?
    It's this one: http://www.jonnyguru.com/modules.php?name=NDReview...

    Word of warning: do not use daisy-chained PCIe power connectors (i.e. one connection to the power supply and two 8-pins to the graphics card). If AMD wasn't going over the per-connector power spec it wouldn't be an issue, but they are, which means you can melt the connector at the power supply end. Those daisy-chained PCIe connectors are meant for 300W max, not 425W.

    We've been hearing about this from a bunch of partners and I believe end users should be warned.

    Thank you. According to specs my PSU could handle these GPU separately, I guess utilizing 2 PCIE slots via 2 separate cards alleviates the strain.
  • extide - Tuesday, April 8, 2014 - link

    No it has nothing to do with how many cards or slots. It's how many CABLES from the PSU.

    Sometimes you can have a single cable with two pcie connectors on the end, one daisy chained of the other. What he is saying is, don't use connectors like that, use two individual cables instead.

    Although, unless the PSU you are using has really crappy (thin) power cables, it should be OK even with a single cable. But yeah, it's definitely a good idea to use two!
