With 11 days to go until the official launch of AMD's Radeon 7900-series graphics cards, PowerColor decided to share some more details about its upcoming cards. The two models appear to be the Hellhound Radeon RX 7900 XTX and the Hellhound Radeon RX 7900 XT, with both cards apparently sharing the same design and cooler. The cards appear to be at least triple-slot, but it's not entirely clear from the provided pictures. PowerColor is using a nine-blade fan design and the fans are of course kitted out with LEDs, where PowerColor is pushing what it calls an "amethyst purple" colour for this generation of Hellhound cards. The new fans are said to improve the GPU temperatures by as much as three degrees Celsius compared to the previous generation of fans.

More importantly, the cards have been given an improved backplate, as well as a larger copper plate for the heatsink, for improved cooling. The new copper plate doesn't just cover the GPU now, but also the VRAM chips. The copper plate is connected to eight 6 mm heatpipes. PowerColor also shared that it's using a 14-layer high TG PCB, which uses a two ounce copper power layer. The RX 7900 XTX is kitted out with 20 VRMs, although this appears to be straight from the AMD reference design. PowerColor appears to have implemented a dual BIOS on the card, as there's a switch for OC/Silent operation and the card also appears to have a hardware LED switch, which is nice for those that don't care about lighting up their computer like a Christmas tree. Keep in mind that this is not PowerColor's top-of-the-range card, which is the Red Devil, so we should expect more details on those cards in the future too.
