AMD Radeon HD 6620G vs AMD Radeon HD 6480G

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.

AMD Radeon HD 6480G

► remove from comparison

The AMD Radeon HD 6480G is an integrated processor graphics card for entry level laptops. It is integrated in the lower mid-range Llano APUs (A4 Series, e.g. A4-3300M) and offers 240 of the 400 shader cores clocked at 400MHz. It offers no dedicated graphics memory (shared memory graphics card) and is therefore slower than similar Radeon HD 6000M cards.

An exception is the HD 6480G in the AMD A4-3305G where it only features 160 Shader but a higher core clock of 593 MHz. However, we expect this version to be slower than the 240 shader versions.

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 of the Radeon 6480G should be in the entry level class of dedicated graphics cards. According to a benchmark by AMD, the 6480G positions itself between the HD 6370M and the HD 6470M. In our gaming benchmarks, the HD 6480G is only on the level of a slow Intel HD Graphics 3000 graphics card. Therefore, modern games like Anno 2070 are playable only in minimum detail settings and low resolutions. Some demanding games like Battlefield 3 wont be playable at all.
