AMD Radeon HD 6550D

The AMD Radeon HD 6550D is a desktop graphics card integrated in the A8 series of APUs (Llano generation). It offers all of the 400 shader cores and is clocked at 600 MHz. It offers no dedicated memory card (shared main memory only that is connected with a 128 Bit Dual channel Interface). The graphics core is based on the old Terascale 2 VLIV4 architecture and used for example in the A8-3800, A8-3820 and A8-3870 quad-core APUs.

The integrated UVD3 video decoder (Avivo HD) is also integrated in the APU and supports Multi-View Codec (MVC), MPEG-4 part 2 (DivX, xVid), MPEG-4 AVC/H.264, VC-1, MPEG-2 and Adobe Flash videos.

Due to the missing dedicated graphics memory, the 6550D is a bit slower than a similar specified desktop or mobile graphics card. In most games the performance is similar to the ATI Mobility Radeon HD 5650.
