the announcements of factory overclocked GTX 570 cards by partners, Zotac has launched its own AMP! version. Zotac decided to go for 780MHz clock for the GPU and bundled the card with Prince of Persia: The Forgotten Sands game.
As noted, the card runs at 780MHz for the GF110 GPU, 1560MHz for 480 CUDA cores and 4000MHz for 1280MB of GDDR5 memory paired up with a 320-bit memory interface. This is a decent factory overclock since the reference card runs at 732 for GPU, 1436 for shaders and 3800MHz for the same amount of memory.
The new Zotac GTX 570 AMP! uses the same reference cooler which is apparently quite sufficient to keep the temperatures on GF110 GPU in check. The card should be available in retail pretty soon and some already have it for pre-order.
