GeForce GTX 570 Closer Look
Aside from the power connections, NVIDIA's GeForce GTX 570 is nearly identical to the GTX 580 in terms of general appearance. Profile dimensions and weight are approximately the same, and both share NVIDIA's vapor chamber cooling solution. Compared to the bulging heat-pipes on the GeForce GTX 480, the GeForce GTX 570 actually looks like it belongs to the GTX 470 family. Both the GTX 480 and the new GeForce GTX 570 have profiles that measure 10.5" long and occupy two card slots, but the GTX 570 drops the 1/2-inch protruding nerf bars and wears a svelte 3.875" waistline. Not surprisingly, it also weighs considerably less, too.
Although the power demands have been reduced, the NVIDIA GeForce GTX 570 still requires two six-pin PCI-E power connections. Similar to the GTX 480 shroud design, the GeForce GTX 570 shares an identical vent near the header panel.
NVIDIA has designed the shroud with a deeper chamfer depression for the blower motor fan, allowing more air to reach the intake whenever two or more video cards are combined in close-proximity SLI configurations.
Popular in the world of CPU coolers, NVIDIA has used a hollow vapor chamber to provide a robust thermal management system on the GeForce GTX 570. This will bring into question the need for add-in card partners to design their own cooling solution, and challenge them to produce better results.
Pictured below is the heatsink component, with the vapor chamber residing inside the copper portion. The polished copper contact surface mates together with the GF110 GPU, as the blower motor fan drives air past the aluminum fins and outside the computer case.
NVIDIA offers a mini-HDMI 1.4a digital A/V output on the GeForce GTX 580, which add-in partners may further extend with a full-size adapter. Dual dual-link DVI digital outputs are retained on the GTX 580, which still means that at least two GeForce video cards will be needed for a NVIDIA 3D-Vision Surround functionality.
