The XFX Double Dissipation HD 7850 uses a cooler that looks almost exactly the same as the cooler used on XFX's other Double Dissipation edition cards. It uses a fairly simplistic metal fan shroud, which actually looks extremely cool. Located on the top of the fan shroud is a red strip of metal. This strip contains the card's name, as well as XFX's "Ghost" technology logo. I'm actually very thankful for this red strip, because it's the only way to tell the HD 7850 and HD 7870 apart. Flipping the card over reveals a nice bare, black PCB.
Unfortunately the XFX Double Dissipation HD 7850 is only equipped with a single Crossfire connector, so you will only be able to Crossfire it with one other card. Powering the card, as is usual now, can be done through the use of two 6-pin connectors.
In terms of connectivity, the user will be able to drive quite a few monitors off of just this one card. You have access to two mini DisplayPorts, a single HDMI port, and two DVI ports. This should make the XFX Double Dissipation HD 7850 very appealing for those looking to run an Eyefinity setup without using a ridiculously expensive videocard.
Separating the card from its cooler is very easy to do. You will however void your warranty by doing so. If you do choose to remove the cooler, you start by removing all of the screws located on the back of the card, and then three screws located on the card's expansion bracket. Once the cooler is completely removed and disassembled we can see that it is equipped with a total of four heatpipes. These heatpipes make contact with the back of a copper plate, which in turn makes contact with the card's core. The heatpipes will then disperse the heat throughout a large chunk of finned aluminum.
With the cooler removed we can see the XFX Double Dissipation HD 7850 in all of its naked glory! Located around the Pitcairn core are a total of eight memory modules. These modules make up all of the card's 2GB of GDDR5 memory, which comes clocked at 1200MHz. Located directly in the center of the card is the Pitcairn core. XFX decided to give us a factory overclock, which brings the final clock speed up to 860MHz.
Now let's take a look at the card's older brother, the XFX Double Dissipation HD 7870!
