AMD Radeon HD 7400G vs AMD Radeon HD 7520G

AMD Radeon HD 7400G

► remove

The AMD Radeon HD 7400G or HD7400G is a processor graphics card in the Trinity APUs from AMD (A4-4355M). It is a low-range version with a reduced shader count / clock speed and will be featured in the A4 series (ULV). It should be based on the VLIW4 architecture of the Radeon HD 6900 series desktop graphics card and wont 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 range of the Llano-based HD 6480G and the Intel HD Graphics (Haswell). Older and less demanding games will run fluently in (very) low settings and resolutions.

The APU is still manufactured in 32nm and, as all A4 ULV parts, should be classified with a 17 Watt TDP. Therefore, the HD 7400G is best suited for small laptops of 11 inch an up.

AMD Radeon HD 7520G

The AMD Radeon HD 7520G or HD7520G is a processor graphics card in the Trinity APUs from AMD. It is a mid-range version with a reduced shader count / clock speed and will be featured in the A6 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, but slower than the AMD Radeon HD 6630M (see for benchmarks). Notebooks equipped with single channel memory will deliver significantly lower performance. Overall, games of 2012 will run fluently with low details.

The APU is still manufactured in 32nm and as A8 series parts are classified with a 35 Watt TDP, the HD 7640G is best suited for laptops of 13-14-inch an up.
