TechPowerUp found some photos of Gainward's GeForce GTX 570 Phantom. This new graphics card features a custom cooling solution with six heatpipes and a large, black aluminium fin array.
Clockspeeds are 750MHz for the core, 1500MHz for the shaders and the 1280MB GDDR5 is clocked at 3900MHz. Display outputs include dual-DVI, HDMI and DisplayPort.
Instead of fans on its obverse side blowing air onto the PCB, there are three fans on its reverse side, drawing air from the aluminum fin array, and onto the PCB. The PCB also seems to be a non-reference design.
The Gainward GTX 570 Phantom uses overclocked speeds of 750 MHz core, 1500 MHz CUDA cores, and 3900 MHz (GDDR5 effective) memory. Like every other GTX 570, it's based on the new 40 nm GF110 silicon, features 480 CUDA cores, and connects to 1280 MB of memory over a 320-bit GDDR5 memory interface.
