PowerColor Devil13 HD7990 Review
Introduction and Technical Specifications
Published: 30th September 2012 | Source: PowerColor | Price: �£799 |
Introduction
Enthusiast based graphics cards, ones that come complete with all the bells and whistles, are usually to be found late in the lifespan of a particular GPU. Today we have a definite switch around of that concept as the PowerColor Devil13 HD7990 has appeared in our offices without much of a fanfare, and certainly without a reference HD7990 being hinted at, much less produced.
It's therefore perfectly possible that this will be the only HD7990 available. Two full-fat HD7970 cores in one card. It reminds us, conceptually, of the ASUS Ares. The Devil13 certainly matches up in terms of ambition and packaging, as well as price.
In some respects we're always nervous about dual-GPU cards. The power requirements and heat issues normally mean that the GPUs are cut-down from the top-end models. However, PowerColor have given us two full on Tahiti XT cores so it will be interesting to see if the card matches up against two solo HD7970s.
We have a lot to cover in this review, so let us crack on.

Still better off with 2 670s/7970s/7950s though.

I wonder if they are partnering with EK or Swiftech to get a block for this thing? I don't know too much about it admittedly.
will not build a card, then so be it, they will. i was really meah.. until the afterburner
overclock and now thats what i think it should have come out of the box. not that
one couldn't do the same, but if left to the suppliers tool for performance, the
buyer would have been a lil sore. leaving a 20% performance gain on the table
at high end cost makes it better, but that should have already been binned for
customer appreciation.
really cool stuff from power color.. keep it up, 'cuz it looks like they are on their own

Only on price. Performance wise you need to go back and check the review / video

Here is my twin 7950 2.1 heaven bench (not 100% sure I've used the same settings as the review though).

Also a 3D Mark 11 performance score. Although I'm not sure of the Devil's graphics score (can't read it from the video) and I'm running on a 3570K so the physics score significantly reduces the Pscore.
I question paying massive amounts of cash on cards that don't do 'everything' tho, mean not 'all the bells and whistles'.
Glad you pointed out the frankly glaring error with logo/ backplate writing. Those are the kind of things that would put me off purchasing things in all honesty. (If i wasn't already such a silence freak).
So i need you guys to help me decide which one that i should pick?
