AMD Radeon HD 7640G vs AMD Radeon HD 7620G vs AMD Radeon HD 7600G

AMD Radeon HD 7640G

► remove

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.

AMD Radeon HD 7620G

► remove

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.

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) is in the mid range of HD 6500M series cards. Most games of 2012/2013 will only run fluently in (very) low settings.

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).

AMD Radeon HD 7600G

► remove

The AMD Radeon HD 7600G or HD7600G is a processor graphics card in the Trinity APUs from AMD. It can be found in the ultra low voltage 19 Watt  A8 versions (e.g. A8-4555M) and offers all 384 Radeon cores. However, the base and Turbo clock rate was reduced from 497/686  in the 7660G to 320/424 MHz in the 7600G. 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.

The performance is in the low range of HD 7500M series cards and similar to the Intel HD 4000. Combined with single channel memory, the card will perform significantly slower.

The APU is still manufactured in 32nm and, as this ultra low voltage part is clasified at 19 Watt, good suited for small or ultrathin laptops.
