Bright Side of News leaked another image of the Radeon HD 6970 that reveals the card's extra-large vapor chamber heatsink design.
This new cooling solution should give the card a pretty good overclocking headroom.
This massive Vapor Chamber cooling is the reason why AMD Radeon HD 6900 Series is achieving remarkable overclocking results, just like the GeForce GTX 580 and 570. We've seen GTX 580 working at 895MHz, GTX 570 at 880MHz as well as viewed results of Radeon HD 6970 clocked at 980MHz, and 6950 at 1010MHz. We've spoken with numerous board manufacturers and they're all telling us that this generation of graphics cards is "vintage", with overclocking headroom spanning much beyond the last generation.
