The white Sapphire HD 7950 Mac Edition was spotted at CeBIT and now Sapphire is officially releasing the card. The card still is more or less a reference design with an 800MHz core clock and 3GB of GDDR5. As far as connections go you have 2x mini-DisplayPort, 1x HDMI and 1x dual-link DVI.
The card is compatible with Apple Mac Pro models from 2010 and a later with an available PCI-Express x16 slot. The card does require power via two six-pin PCIe power cables, they are included. One interesting thing about this card is that it can be used on Windows machines as well. It comes equipped with a simple dual BIOS switch that allows you to switch it from Mac and Windows modes.
No word yet on pricing although we have heard the $450 MSRP flying around. We were unable to find the card for sale.

I wonder what is the difference between Mac and Windows mode.
From the press release, “The SAPPHIRE HD 7950 Mac Edition can also be used in the latest PC architectures. It has Dual Firmware support via a simple Firmware (Dual BIOS) switch. In one position the Sapphire HD 7950 MAC Edition supports Mac OS X/Windows under non-UEFI compliant mode and in the other it supports Windows with UEFI hybrid firmware enabled. A Windows driver disk is also included.
Under Windows, additional features are supported, including hardware acceleration of video decoding, HDMI audio pass through and additional display resolutions”
