XFX Radeon HD 7770 Double Dissipation Black Edition Pictured
 

Here is the first picture of XFX' flagship graphics card based on the AMD Radeon HD 7770 GPU, the XFX Radeon HD 7770 Double Dissipation Black Edition. The picture reveals that XFX is sticking to a slightly-modified version of the AMD reference PCB, its variations don't appear to go beyond a red-colored DVI connector. It's the cooler, where all the action is. XFX used a slightly downscaled version of the "Double Dissipation" cooler it designed its Radeon HD 7900 series graphics cards with.

The cooler appears to use large copper plate that makes contact with each of the aluminum fins that run the entire length of the card. These aluminum fins are then ventilated by two fans that spin at low speeds (low noise), ensuring even ventilation, and better cooling compared to AMD reference cooling solution. A picture of a portion of the product box has text that claims this cooler is up to 13 dBA quieter than the reference design cooler, and up to 7 °C cooler. The "Black Edition" moniker would indicate that this card is factory-overclocked.
