Meet the XFX R7770 Black Edition S Double Dissipation

Our final card of the day is XFX’s R7770 Black Edition S Double Dissipation, one of a multitude of Radeon HD 7770 cards XFX will be releasing today. XFX will be releasing two factory overclocked Black Edition cards today, with the S edition BESDD being the higher clocked of the two. It will be clocked at 1120MHz core and 5.2GHz memory, which is a 120MHz (12%) core overclock and 700MHz (15%) memory overclock compared to the reference 7770.

Like all the other 7770s being released today XFX is using the AMD reference PCB for the BESDD, so XFX is primarily relying on their factory overclock and their custom cooler to stand apart from AMD’s other partners. To that end the BESDD is very similar to the other XFX Double Dissipation cards we’ve reviewed in the last month. A copper plate sits at the base of the cooler, transferring heat to an aluminum heatsink that runs virtually the entire length of the card. Above that sits a pair of fans and then finally the metal shroud that covers the card.

Overall the design is similar to a number of other dual fan cards we’ve seen in the past, and as we’ll see in our benchmarks the resulting cooling is quite effective. In terms of quality however I feel XFX has missed the mark – the cooler is only attached to the PCB around the GPU, so at 8.25” long there’s nothing retaining the PCB at the far end to keep it from flexing. A stiffener would have been a great idea here, which is something XFX does on the 7900 series. Furthermore in the case of our sample the construction quality was also subpar, as the screws responsible for securing the metal shroud were not properly tightened and thereby leaving the shroud loose. This is nothing 30 seconds with a screwdriver couldn’t fix and I don’t have any reason to believe this is a common problem, but it’s a quality control issue none the less.

As the BESDD uses AMD’s 7770 PCB, the length of the card and display connectivity is identical. The card measures 8.25” long with no cooler overhang, while display connectivity is provided by 1 DL-DVI port, 1 HDMI port, and a pair of miniDP ports.

Rounding out the package is the same collection of extras that we saw in the 7950 BEDD. Inside you’ll find the usual driver CD and quick start guide, along with a metal XFX case badge, a mid-length CrossFire bridge, a DVI to VGA adaptor, and a passive HDMI to SL-DVI adaptor. All of this is packed in one of XFX’s pleasantly small boxes, which doesn’t use much more space than the card itself.

The MSRP on the R7770 BESDD is $184, $25 over the MSRP for a regular 7700 and pushing it well into the territory of the Radeon HD 6870 and GeForce GTX 560. XFX is offering a base 2 year warranty on the R7770 BESDD, which can be extended to a lifetime warranty by registering the card within 30 days of purchasing it.

    I thought the 7770 would outperform the 6850 at least. Great review. Reply

    For AMD cards, you look at the second number to indicate performance. An 8 series card like in the 6850 usualy performs as well or slightly better than a next generation 7 series card like the 7770.

    The 3rd number also indicates performance, but not nearly as much as the second number.

    er, not really. A 58xx is faster than a 68xx. Reply

    The 68xx series introduced an anomaly in the formula. But generaly what I stated is true. Reply

    The anomaly here is the NVIDIA Gtx460 SMOKES the 7770 on everything, in every test, and costs 33% less.
    I see the crazed fan base cannot bring themselves to say it.
    I'll say it - 19 pages unsaid, over a long time.

    My word you are tiresome. Reply

    Using your logic a gtx 580 smoke the gtx 460.

    The reason why 7770 costs a bit is because its new technology, power consumption goes down quite a bit. Compare the card to same power consumption of new generation card maybe a 7870 and the 7870 will smoke the gtx 460.

    perferformance per watt 7770m smokes the gtx 460.

    you seriously need to stop posting. everything you post comes off as rabid nvidia fanatic, because you evidently are one, and you seem to camp outside these benchmarks to say the same thing everytime!! "this thing SMOKES~~~~!! the 7770!!! thats all i look at are the frame rates!!! i dont take anything else into consideration cause im an nvidia superfan" Reply

    Really? I thought the 6870>5850. No? Reply

    This 7k series needs some
    LOL - How low can you go amd ?
    Seems like more firings and cullings are in the works - or perhaps they already dragged the cat in and are now stuck with perverts.
