TechPowerUp spotted a photo of an upcoming Radeon HD 5570 based graphics card from Unika. This short DX11 card appears to use a 128-bit memory bus and 1GB GDDR3 memory.
The card by Unika is hardly any longer than the PCI-Express interface itself, from which it draws all its power. The GPU is cooled by a custom active fan-heatsink. Connectivity includes DVI, D-Sub, and HDMI. Clock speeds include 650 MHz for the core, and 900 MHz (1800 MHz DDR) for the memory. The GPU is DirectX 11 compliant, and supports UVD 2.0. Expect more details about the GPU to surface at the CES event.
