The AMD Radeon HD 7640G or HD7640G is a processor graphics card in the Trinity APUs from AMD. It is the second fastest version and is featured only in the A8 series. It 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 is in the mid range of HD 6000M series cards similar or slower than the AMD Radeon HD 6630M (see for benchmarks). Therefore, the graphics card is a bit faster than the Intel HD Graphics 4000 in Ivy Bridge CPUs.
The APU is still manufactured in 32nm and as most A8 series parts should be classified with a 35 Watt TDP, the HD 7640G is best suited for laptops of 13-14-inch an up.
