AMD Radeon HD 6620G
The AMD Radeon HD 6620G is an integrated processor graphics card for mainstream laptops. It is integrated in the fastest Llano APUs (A8 Series) and offers all 400 shader cores clocked at 444MHz. It offers no dedicated graphics memory (shared memory graphics card) and is therefore slower than other Radeon HD 66x0M cards.
The new UVD3 video decoder supports the decoding of MPEG-4 AVC/H.264, VC-1, MPEG-2, Flash and now also Multi-View Codec (MVC) and MPEG-4 part 2 (DivX, xVid) HD videos on the graphics card.
The performance should be on a level of a Mobility Radeon HD 5650 graphics card. Therefore, modern 3D games of 2011 should run fluently in medium to high details in 1366x768. The Intel HD Graphics 3000 card in the Intel Sandy Bridge processors is clearly slower in comparison.
