At CeBIT, AFOX showed off the industry's first single-slot, air-cooled graphics card based on the Radeon HD 7850 GPU. Carrying the model number AF7850-1024D5S1, AFOX' creation sports a similar cooling assembly as the one on the AF6850-1024D5S1, an HD 6850-based graphics card. The cooler uses a big lateral-flow blower that directs air through a dense aluminum fin-channel array, where heat gets dissipated onto it. Heat is drawn from key components such as the GPU, memory, and VRM, using a vapor-chamber plate.
There's a small catch with AFOX' design, though. The memory amount is halved to 1 GB, although it still sits across a 256-bit wide memory interface. We don't expect a significant performance penalty for that. Further, the memory clock speed is reduced from the reference speed of 1200 MHz to 1125 MHz (4.80 GHz eff. to 4.50 GHz eff.), although the core speed stays the same, at 860 MHz. The display IO is an interesting mix of one dual-link DVI, one full-size HDMI, one mini-DisplayPort, and one full-size DisplayPort.
