Fitted with a glossy white shroud, Sapphire’s Radeon HD 7950 Mac Edition graphics cards are meant for Apple Pro workstations. The cooling design is similar to AMD HD 7950’s reference version, but it comes with a custom black PCB design and a firmware to make it work with Mac Pro.
As far as specs are concerned, it comes with the clock speed of 800MHz and 5 GHz memory clock with 3GB 384-bit GDDR5 interface taking power via 2x 6-pin PCIe connectors. It uses Dual-link DVI, HDMI and 2x mini DisplayPort for display output. It is speculated that this card will be priced between 400 Euros and 500 Euros, a substantially larger premium in comparison with the standard reference version of HD 7950 which costs about 250 Euros.
