It has an Intel proc and uses PCIe (like a PC), but you cannot install a standart GeForce or Radeon graphic card in it. You need a special version for which you have to pay a premium.
EVGA, a premium maker of Nvidia GeForce graphics cards, has quietly unveiled one of the world’s highest-performance graphics cards for Apple Macintosh computers, the GeForce GTX 680 Mac Edition. The new graphics card will turn outdated Mac Pro desktops into a gaming powerhouse and will thus make the platform more competitive.
“Get to the next level with the EVGA GeForce GTX 680 Mac Edition. This card delivers truly game-changing performance that taps into the powerful new GeForce architecture to redefine smooth, seamless, lifelike gaming. It offers brand new, never before seen features that will redefine the way you think about performance graphics cards,” a statement by EVGA reads.
EVGA GeForce GTX 680 Mac Edition 2GB graphics card is based on the GK104 graphics chip that features 1536 stream processors, 128 texture units, 32 raster operating units as well as 256-bit memory bus. The chip is clocked at 1006MHz (with up to 1058MHz boosted clock-speed), whereas 2GB of memory operate at whopping 6.008GHz. The novelty fully supports modern high-end features like DirectX 11.1, OpenGL 4.2, OpenCL 1.2, stereoscopic-3D, 4 multi-monitor capability, PhysX, 4-way multi-GPU, PCI Express 3.0 and so on. Since Apple limits compatibility of hardware with its PCs, the new EVGA GeForce GTX 680 Mac Edition will come with a special BIOS.
Late last year it transpired that Apple’s Mac OS X 10.8.3 developer preview includes driver support for the latest high-end AMD Radeon HD graphics cards based on GCN architecture as well as advanced Nvidia GeForce GTX graphics boards based on Kepler architecture. Since Apple currently does not officially install such graphics cards into its systems, it became apparent that the company is either getting ready for the next generation of Macs or wants to provide upgrade paths for the current-gen Mac Pro and possibly other systems. As it appears, Apple decided to open up upgrade opportunity for its customers and let third-party add-in-board makers to offer graphics cards options for Mac Pro. Back in March Sapphire introduced Radeon HD 7950 Mac Edition.
EVGA GeForce GTX 680 Mac Edition 2GB will cost much more than similar graphics adapters for Windows-based PCs. The graphics card will cost $599 and will be available shortly.
