AMD Radeon HD 7950 Review Feat. Sapphire & XFX: Sewing Up The High-End Market
by Ryan Smith on January 31, 2012 9:02 AM ESTMeet the XFX R7950 Black Edition Double Dissipation
Our second partner card of the day is XFX’s R7950 Black Edition Double Dissipation. Like the 7970 Black Edition Double Dissipation we reviewed earlier this month, the 7950 BEDD is a factory overclocked card (Black Edition) using XFX’s Double Dissipation cooler.
Starting with the overclock, XFX is shipping the 7950 BEDD with a core clock of 900MHz and a memory clock of 5.5GHz. This represents a 100MHz (12.5%) core clock overclock and 500MHz (10%) memory clock overclock, putting it just shy of the 925MHz core clock the 7970 ships at.
In terms of construction like all of the other 7950 cards launching today XFX is using AMD’s 7950 PCB. This means the PCB measures 10.25” long and features 2 6pin PCIe power sockets towards the rear of the card, while at the front the card uses the AMD standard port configuration of 1 DL-DVI, 1 HDMi, and 2 mini-DisplayPorts. The one notable deviation here from the Sapphire card is that XFX has not included a BIOS selection switch, so the card lacks any kind of ability to easily recover from a bad BIOS flash, and if unlocking proves viable it would not be a good candidate for the process.
Meanwhile cooling is provided by XFX’s Double Dissipation cooler. This is the same heatsink and fan assembly we saw with the 7970 BEDD, which makes this an open air cooler using a pair of fans to push air along an aluminum heatsink running almost the entire length of the card. Because it’s the same assembly, the shrouding for the card sticks out over the end of the PCB, negating the benefit of the shorter 7950 PCB and making the card 10.65” long just like the 7970 BEDD.

Do note that while it uses the same fan and heatsink assembly, Double Dissipation does not mean it uses the same vapor chamber assembly to transfer heat from the card. Where the 7970 BEDD used a fairly large vapor chamber, the 7950 BEDD uses a much smaller vapor chamber that only makes contact with roughly half of the heatsink, meaning that heat isn’t being transferred to the extremities of the heatsink nearly as well on the 7950 BEDD. Furthermore the aluminum plate covering the RAM and MOSFETs is poorly sized, leaving parts of the RAM chips (and their thermal pads) exposed. We’ll see how this plays out when we get to our testing, but the 7950 BEDD is clearly not as well built as the 7970 BEDD.
Rounding out the package is the same collection of extras that we saw in the 7970 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, 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 7950 BEDD is $499, $50 over the MSRP for a regular 7950 and making it one of the more expensive 7950s launching today. XFX is offering a base 2 year warranty on the 7950 BEDD, which can be extended to a lifetime warranty by registering the card within 30 days of purchasing it.

I think it's you that has been sleeping. You're comparing EBay prices for god sakes. We are talking about new releases.The 5870 released 2 1/2 years ago at 379$. It was 2x as fast as the 4870.
When the 4870 released it cost what, 300$ in mid 2008. It was over 2x as fast as the 3870.
How about the amazing 9700pro at around 400$, In some cases being 4X faster then the 4600TI.
This is perhaps a step up from the to the likes of the 2900XT or 5800ultra. But both of those had some rocking competition to deal with. Like the 8800GTX and the 9700pro.
If you think this 30% better performance is worth 580$ then you have no concept of value.

It took you long enough to notice. Better to go and have this discussion in the comments of the HD6970 review.Galidou - Tuesday, January 31, 2012 - link
Because it's next gen, performs better for the same price and overclocks probably WAY better plus maybe a chance to mod it to 7970? Is that enough?SlyNine - Tuesday, January 31, 2012 - link
Its not better performance for the same price. This time the price has scaled with performance.Normally when a new GPU gen releases its much better performance at the same price as the previous kings release.
Look at the 9700pro, 8800GTX, 5870. Those were great cards for the time. The 7970 is just, Eh. Not bad enough to be considered a 2900XT or a 5800 Ultra. But at least those 2 cards had much better competition.

Actually, AMD's prices for these cards are SO bad, most people will just wait or buy older tech. Hell at least Intel's Sandy Bridge i5-2500K came out at a reasonable $215 which really isn't that high for the performance you get from it... in fact, there is no other CPU at the same price that even comes close, nor was there a CPU last year for the same price that even comes close. Here, AMD is pricing themselves out of the market.mdlam - Tuesday, January 31, 2012 - link
Right, and their egregious pricing mistake is why all their cards are selling out since launch. Because all of AMD's business MBA's and experts are no match for your idea of "a good deal"Maybe you've noticed that things are usually more expensive at launch because of hype, and the fact that you have the fastest card makes pricing irrelevant. Well hell whatever, you didn't even notice that Sandy bridge 2500k opened up at $260-270 dollars at launch, what's the point in taking this further.

I noticed that when the 5870 and 5850 came out they blew away the competition and were relatively cheap. What was the 5850 price when it came out - about half of the 7950? Yet the performance leap over previous gen for 5850 was much larger then for 7950. That's why everyone is a bit disappointed.gibsnium - Tuesday, January 31, 2012 - link
The 2500k launched that the same price it is today; bought one from newegg at 219$ at launch.

doesn't anyone else remember when the 8800 ultra was released and Nvidia threw a thousand dollar price tag on it???how short are your memories??

I remember it can barely run crysis
