AMD's upcoming Llano line of accelerated processing units (APUs), to compete with Intel's Sandy Bridge LGA-1155 processors, is said to embed what AMD will refer to as the Radeon HD 6550 graphics core. Unlike Sandy Bridge where a processor die is simply fused with a integrated graphics northbridge onto a single die, Llano will see the GPU part of the silicon integrated with the rest of the APU in many other levels, including assisting the x86 cores with serial processing loads. Llano's embedded GPU carries the AMD Radeon SKU of HD 6550. It will feature on AMD's Fusion A8-3550 and A8-3550P APUs, is DirectX 11 compliant, has 400 stream processors, and a core clock speed of 594 MHz. It uses memory shared from the main memory, but in all likelihood, AMD might work on SidePort-based memory support. Further, the Radeon HD 6550 can work in tandem with discrete AMD Radeon HD 6570 and HD 6670 "Turks" based graphics cards in the same way as AMD's IGPs have been known to work with entry-level Radeon GPUs using Hybrid CrossFireX. When the HD 6550 iGPU is working in tandem with HD 6670 or HD 6570, the graphics hardware will be recognized as "Radeon HD 6690".
