AMD Radeon HD 7400G vs AMD Radeon HD 7420G

AMD Radeon HD 7400G

► remove from comparison

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 7420G

► remove from comparison

The AMD Radeon HD 7420G or HD7420G is a processor graphics card in the Trinity APUs from AMD (A4-4300M). It is a low-range version with a reduced shader count / clock speed and will be featured in the A4 series. It should be based on the VLIW4 architecture of the Radeon HD 6900 series desktop graphics card and most likely 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 somewhat below the Llano-based HD 6620G or in range of slower versions of the HD Graphics 4000. Most modern games of 2013/2014 won't run fluently even in (very) low settings; however, older and less demanding games can be played smoothly.

The APU is still manufactured in 32nm and as most A4 series parts should be classified with a 35 Watt TDP, the HD 7420G is best suited for laptops of 13-14-inch an up.
