NVIDIA, the leading GPU manufacturer today announced new and much fasterGeForce GTX 680MX and GTX 675MX graphic processing chips for the latest Apple iMac 2012.

Equipped with more and faster cores, theGeForce GTX 600MX notebook GPUs deliver premium performance with anenhancedpowerefficiencydesign. Following are the detailed specifications of NVIDIA's new mobile GPUs:

GeForce GTX 680MX

The GeForce GTX 680MX becomes NVIDIA's fastest mobile chipequippedwith 1536 Cuda cores clocked at 720 MHz. The chip would support a GDDR5 memory interface clocked at 2500 MHz along a 256-bit interface. The new chip offers support for3D Vision, 3DTV Play, CUDA, DirectX 11, PhysX, SLI, TXAA, Adaptive VSync, FXAA and can be 2-Way SLI'd.

Press Release

Apple consistently demonstrates its knack for designing exciting new products that are thinner and lighter, and deliver more performance than the generation they replace. And the all new iMac follows that trend.

Within Apple’s slim new 21.5- and 27-inch iMacs are NVIDIA GeForce GPUs, based on our new Kepler-class architecture, which helps make them up to 60 percent faster than last year’s models. This follows news in June that Apple’s 15-inchMacBook Pro with Retina displayuses Kepler GeForce GPUs.

The new 27-inch iMacoffersthe GeForce GTX 660M as its base GPU, with even faster GeForce GTX 675MX or GeForce GTX 680MX GPUs available. The 21.5-inch modelcomes withthe GeForce GT 640M GPU, with an available upgrade to the GeForce GT 650M GPU.

Apple is synonymous with top-performance, high-quality products, so we suspect that it’s no coincidence that the new iMac uses GeForce. Kepler’s unprecedented performance and incredible power efficiency make it a great fit for the sleek new iMac.
