Results: 1080p With Max Settings
We're using the 2014 VGA Charts database for comparative benchmarking. This gives us a great basis for creating an index with all games and tests taken into consideration. If you want the individual test results, check out the charts section itself, where you'll find all of the individual numbers composing the index and have the option to create comparison tables.
Gaming at 1920x1080
We start by testing at FHD and maxed-out settings, even though that's well below the target market for a flagship dual-GPU board. PowerColor's Devil 13 lands right where we'd expect it relative to AMD's reference Radeon R9 295X2. That is to say the air-cooled model is just a bit slower given its more moderate power consumption. The only benchmark where the Devil 13 inches out its competition is 3DMark Fire Strike, due to the card's tuned memory subsystem. Unfortunately, you can't play a synthetic metric. But we still have to be impressed that traditional heat sinks and fans can keep up with two Hawaii GPUs.
Manually increasing the clock rate of PowerColor's Devil 13 to 1018 MHz and increasing its power target to match AMD's Radeon R9 295X2 yields almost identical benchmark results, interestingly enough.
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.
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.
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.
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.
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.
