AMD Radeon HD 7620G
The AMD Radeon HD 7620G or HD7620G is a processor graphics card in the Trinity APUs from AMD. It is built into the low voltage 25 Watt A10 versions (e.g. A10-4655M) and offers all 384 Radeon cores. However, the base and Turbo clock rate was reduced from 497/686 in the 7660G to 360/497 MHz in the 7620G. The architecture is based on the VLIW4 architecture of the Radeon HD 6900 series desktop graphics card and doesn't offer a dedicated graphics memory.
Trinity got its name due to the fact that it consists out of three different architecture parts. The CPU cores are based on the Piledriver architecture (Bulldozer successor), the GPU cores on Northern Islands GPU cores (HD 6900 desktop series) and the video processing engine and multi-display connectivity from the new Southern Islands GPU architecture (HD 7900 series).
The integrated UVD3 video decoder (Avivo HD) allows the full decoding of Multi-View Codec (MVC), MPEG-4 Part 2 (DivX, xVid), MPEG-4 AVC/H.264 and Adobe Flash HD videos.
The performance (with dual channel memory) should be in the mid range of HD 6500M series cards where the rating in the synthetic benchmarks like 3DMark 11 is expected to be higher than the actual game performance (as was the case for the 7660G).
The APU is still manufactured in 32nm and, as the low voltage parts are clasified at 25 Watt, good suited for small laptops (but not ultrathin, as the HD 7500G is intended for these subnotebooks).
