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.

Time for the DOJ to start looking into the price fixing that's going on here.A5 - Wednesday, February 15, 2012 - link
Price fixing is explicit, purposeful collusion between 2+ manufacturers to set prices at an unnaturally high level. For an example, see the memory market in the early 2000s.That is not what is happening here.

Both of these companies settled price fixing lawsuits in 2008 under similar circumstances. They've cheated before; don't be surprised if they're cheating again.mckirkus - Wednesday, February 15, 2012 - link
If Coke and Pepsi both start pricing cans of soda at $50 each, doesn't mean people will buy them. The 7770 is a $50 can of soda.CeriseCogburn - Wednesday, March 21, 2012 - link
Yeah sure is price fixing when the always victorious gtx460 is $110 bucks and beats the 7770 every time and there's a large stock available...Or the other, triple fan GTX580 at the egg for $359, and the other reduced way down from $500.
AMD is scalping we customers even now and has been since before this review.

There's an easy solution to price fixing: Don't buy at their asking price, or buy the faster, last-gen for cheaper.Its not like GPUs go bad like produce or get consumed like oil. Just keep using whatever you have in your rig now, because chances are its just as fast at a cheaper price than what AMD is asking for these "new" next-gen parts.

meh I'm not worried about it just yet, it's too early... I bet it's because of poor yields, which would make the pricing legitimate... remember it's a new arch on a new nodeif the situation is the same in a month or 2, i'll be among those complaining

I guess AMD is gonna let go of the old 6850 quick, 'cause no one is gonna buy it with this prices. Perf/watt very good tho, although mem bandwith very dissapointing. DDR4 is not coming soon enough, let alone GDDR6. 128 bits are simply not enough and 256 bits is adding more power/complexity. Can't wait for the day when GDDR6 comes and hopefully doubles bandwith for lower power/efficient clock speed. Oh, and gpu companies, when that day comes, don't be stingy like you always are and end up giving us 64 bits instead.silverblue - Wednesday, February 15, 2012 - link
Bring back TBDR and you won't need stupidly wide memory buses. ;)Roland00Address - Wednesday, February 15, 2012 - link
This is figuring out the price per performance, how many dollars you have to spend to get each FPS. Using Anandtech's Crysis: Warhead: 1680x1050 Gamer Quality Everything, Enthusiast Shaders+4xAA (Lower is better since you get a better bang for your buck.) Prices are from Newegg, using the cheapest card out there, no MIR are factored in, price includes shipping. Notes the 7750 and 7770 are not on newegg yet, so I am using the MSRP with no shipping to figure out the FPS per dollar. The GTX460 is using an older anandtech test since it is no longer using the more recent benchFPS Per Dollar/Video Card/FPS/Price/Shipping/Total
$3.81 Radeon 5750 28.1 99.99 6.98 106.97
$3.23 Radeon 5770 32.5 104.99 0.00 104.99

3.88 Geforce GTX550 TI 32.7 119.99 6.98 126.97
3.56 Geforce GTX460 1GB 41.4 139.99 7.56 147.55
3.65 Geforce GTX560 48.5 169.99 6.98 176.97
As you can see, the Radeon 7750 is actually a very good card for its price. It beats the old Radeon 5770 series, and all the Geforce only losing to the Radeon 6800 series in the terms of value. Don't forget though the Radeon 7750 can be single slot, doesn't need a 6 pin, and generates less noise and heat.
The 7770 on the other hand is the most expensive card in the terms of value. Notice that Geforce cards have a higher dollar per fps (they have less value), for the Radeon card to succeed it only has to compete with Geforce since Radeon still makes money if you buy one of the other Radeon cards. If the 7770 was priced at 131.01 it would have identical value as the gtx460 1gb, and 142.78 if the card was priced against the value of the GTX550 TI.
I wouldn't be surprised that the Radeon 7770 will drop to the 139.99 or 149.99 price range once all the older 5700 series and 6800 series leave the channel. I do not think we are going to see much cheaper 7750s though since it is a recycled part and its price per performance is very good already. OEMs are going to be eating up the 7750s like candy.
