PowerColor Devil 13 Dual Core R9 290X 8 GB Review: Dual Hawaii on Air

PowerColor’s Devil 13 graphics card, with its two Hawaii GPUs and massive heat sink, weighs in at more than two kilograms and exudes luxury. But can it compete with AMD’s dual-GPU reference design with closed-loop water cooling? Let’s find out!

Temperatures, Noise, And Videos

Temperatures

The Asetek closed-loop liquid cooler AMD uses for its Radeon R9 295X2 performs as well as can be expected in spite of its miserly 120 mm radiator. It beats PowerColor's Devil 13 board without breaking a sweat. Though, that card, in turn, isn't bad for an air-cooled offering with two high-end GPUs.

We decided against testing the PowerColor Devil 13 inside of a case in order to protect our hardware. The card with the PCIe connectors on top is too tall for our reference chassis, and its included holder, the “PowerJack,” is too small for our alternative full tower, Corsair's Obsidian 900D. As you think about the hardware you'd pick to go with this graphics card, bear in mind that if PowerColor's PowerJack fits, the Devil 13 should sit securely. But you have to put more effort into coordination than most other configurations.

Fan RPM

In order to manage thermals effectively, the fans must provide a certain level of air flow, of course. This gives us a nice segue to our noise section. The fans on PowerColor's Devil 13 card behave interestingly in performance mode. A number of slow-downs are apparent in our log of rotational speed; these are reflected in the temperature curves, too.

Noise Measurement

Graphics cards noise measurements are performed using a calibrated high-end studio microphone (supercardioid) positioned perpendicular to the middle of the graphics card in question at a distance of 50 cm. This distance, in conjunction with the very strong cardioid directionality of the microphone, represents a compromise between avoiding noise due to fan turbulence and avoiding ambient noise, which can never be completely eliminated.

We performed measurements after each card reached its operating temperature in our gaming loop. Even though the Devil 13 offers both quiet and performance settings, you don't get a significantly better experience in quiet mode. The two firmware options have PowerColor's card competing with AMD's Radeon HD 6990 to become the loudest board we've tested recently.

Unfortunately, this noise level is truly unbearable, even with quiet mode activated and the card in a case. Again, we have to give AMD credit for its water-cooled Radeon R9 295X2. The Devil 13 ends up coming across as an interesting demonstration of what's possible, or what an air-cooled 295X2 might have looked like.

Comparison Videos

Finally, we'll give you a listen to how PowerColor's Devil 13 Dual Core compares to three generations of dual-GPU reference cards from AMD. The numbers don't tell the whole story, after all.

    Looking at page 4, that screen is insane!! Love it!

    Was this card staying at 1000Mhz during those benchmark runs?
    The FPS difference at 1080p is ~7%, yet the clock difference is less than 2%.

    Also,
    Did you find the Devils maximum stable overclock? With all that power available, I'd imagine this thing could achieve better overclocks than the 295x2.

    OC makes no sense, because the card will be really loud. And please read the review attentively! The performance difference between both cards reflects the difference in power consumption nearly 1:1! To handle this cooling by air, the power color card uses a lower power target. Since AMDs Power Tune and Nvidias Boost the pure core clock rates says nothing about the final performance! In my eyes this is also a good study about the limits of an air-cooler.

    Take a look at the page with the HiRes power draw. This card isn't a perpetuum mobile. Less power consumption = less gaming performance. OC brings really nothing. Ok, you can destroy your ears... (or the card). We had to handle this rare card very carefully, so I was not able to break the voltage barrier.

    "Destroy my ears"?
    "OC makes no sense because the card will be really loud"? Are you serious??????
    Since when has that stopped anyone?
    This thing is quiet compared to high end cards from 5+ years ago....

    Have we become so spoiled by the advances in technology, that has enabled higher performance at lower noise levels, that we will not push the limits in fear of a little noise!?


    It's an ultra high end GFX card made for the kind of people who like to push the limits. It should absolutely be overclocked and benchmarked. With a big fat mind-blowing power usage chart with figures higher than any card has ever pushed!

    Also, clock rates still directly correlate to performance. Lowering the power tune limit will limit clock rates, and vice versa. Lower clock rates equals lower performance, but lower power does not always equal lower performance.

    I just got done reading 3 other reviews for this card, and each of those reviews had this card slightly above the 295x2 in their gaming benchmarks. (despite the Devil's boost clock being slightly lower).
    That seems a little odd.

    The games, game settings, drivers, average clock rates, and Bios mode used for the benchmark figures/comparison, are not listed in this review. (unusual for Toms) That information would be very helpful.
    I suspect that the 295x2 was maintaining a higher average clock rate, in this comparison. (higher than 2%, anyways)
    PowerColor, almost certainly made sure that this card meets-or-beats the performance of the 295x2, before sending it off for review.

    It's interesting to see this kind of enormous, powerful, noisy card being developed in a market where most games are designed to fit the limits of console hardware.

    Why have they called this a 290X? Rather confusing, it should be called a 295X.
    Having it listed in the 290X section on seller sites is dumb. Also, it's not an 8GB
    card, it's a 2x4GB card. I really wish tech sites would stop GPU vendors from
    getting away with this inaccurate product spec PR. Call it for what it is, 2x4GB,
    and if vendors don't like it, say tough cookies. The user will never see '8GB' so
    the phrase should not be used as if they could (though PowerColor seems happy
    to have such misleading info on its product page). I'm assuming you agree with this
    Igor, because the table on pp. 11 does refer to the Devil 13 as a 2x4GB... ;)

    Btw, checking a typical seller site here (UK), the cheapest 290X is 1040MHz core,
    so given the Devil 13 uses 3 slots anyway, IMO two factory oc'd 290Xs make more
    sense, and would save more than 300 UKP.

    PS. The typo Mac266 mentioned is still present.

    Why did the person who wrote this article focus primarily on power consumption and efficiency?

    This review has 4 pages of power consumption/efficiency data, with some impressively detailed information. But, it only has 2 pages of actual performance data, with almost no details at all.

    Who wouldn't want to see this card overclocked to a ridiculous extent, with plumes of smoke coming off of it, and the only power consumption figures showing that it's consuming more power than any other card ever made?


    (I had to edit this comment. That first revision was a little crazy.)

    The performance is so close to the performance of the liquid-cooled R9-295X that it would basically be a repeat of that review. If you want an idea of its performance, just re-read that review and maybe reduce each frame rate by 3%-ish.

    OT: 60Db? Into the trash it goes. I don't care how expensive a card is, if it's too loud that I can't have a goddamn normal conversation near my computer, it's going in the skip. I don't want to surround myself in an anti-social bubble of noise-induced hearing loss every time I want to game.
