The XFX HD6790 DD arrives in an eye catching box with the ‘DD' lettering the primary focus of the design.
The bundle contains literature on the XFX range, including their power supplies which we have reviewed before on Kitguru. They also supply access to their indepth support system, ensuring customers have live support if problems occur. Finally there is a sign for a door, to ensure you aren't interrupted when you are viewing por…. I mean playing games.
The card is constructed around an attractive black PCB which features anti tamper stickers over the locking screws at the rear. No applying your own paste without invalidating your warranty it seems. We will take the card apart shortly however as we don't care about warranty.
The front of the card is cooled by a large, dual fan system, in matching black. There is a hefty copper heatpipe configuration at the top of the card with the a ‘Double Dissipation' sticker above them.
The HD6790 is Crossfire capable, in a two way configuration and it requires two 6 pin power connectors to operate correctly.
The HD 6790 DD has two DVI ports on the I/O plate, with a full size HDMI connector and two mini displayport connectors. There is full support for AMD Eyefinity, although to power games across multiple monitors you will probably need to invest in two of them. We like how XFX cut their logo into the backplate.
Getting access to the board requires mounting screws, backplate screws and PCB screws to be removed. The cooler looks great, with three thick direct contact copper heatpipes leading into two separate racks of aluminum fins on either side of the core.
XFX are using 1GB of high quality GDDR5 Elpida memory on the custom PCB.
Above, a GPUz screenshot of the XFX HD6790 DD. It runs at 840mhz core and 1050mhz via the 1GB of GDDR5 memory (4200mhz effective) which is connected via a 256 bit interface. The card is based on the 40nm AMD Barts core and has 800 unified shaders and 16 ROPS.
Very nice indeed, HD6870 is by far b est value, thats a bargain.
Excellent, I agree HD6870 is best and its very well priced. I dont get paid for 2 weeks sadly 🙁
Thought they had vanished off the face of the earth there for a while. nice to see them back … with a bang.
Never mind the 6870, the 6790 is really more than most people would ever need, quite surprised how well it performs even at 1080p. But for the small price increase, 6870 is much better value.
Very good, thanks for review.
I like XFX< always had good luck with their cards. shame they stopped the cool X shaped boxes they used to have.
are they the first to have used a direct touch heatpipe cooler like this?
Two of the HD6870s seem best to me, just a little more than one of the 6950’s.
They should lower the 6950 price to £199 inc vat IMO or even £190.
Great review man, im really looking at one of those 6790s for my media center, but it seems poor value when the 6870 is only 25 quid more.
6870 FTW. those are great cards. XFX DD version is a bargain, orfered one.
really cool. And the price isn’t really bad…
