AMD Fusion is the marketing name for a series of APUs by AMD. There are two flavors of Fusion currently available, one with its CPU logic based on the Bobcat core and the other its CPU logic based on the K10 core. In both cases the GPU logic is HD6xxx, which itself is based on the mobile variant of the Radeon HD 5xxx Series. Fusion was announced in 2006 and has been in development since then. The final design is the product of the merger between AMD and ATI, combining general processor execution as well as 3D geometry processing and other functions of modern GPUs (like GPGPU computation) into a single die. This technology was shown to the general public in January 2011 at CES. In the same year AMD will introduce Bulldozer for Socket AM3+ and for the server market.
