AMD Radeon HD 7570M

The AMD Radeon HD 7570M (sometimes also called AMD Mobility Radeon HD 7570) is a DirectX11 middle class graphics card for laptops. It is based on the same chip as the Radeon HD 6630M, but only 5 SIMD-engines (= 400 shader) are activated. Furthermore, the memory interface is only 64 bit wide, but supports DDR3 and GDDR5. Depending on the version, the core clocks are between 450 an 650 MHz. The architecture is based on the Northern Islands generation, manufactured in 40nm.

The 400 stream processors should be still based on the "old" 5D architecture similar to the 5000 series. Therefore, the number of shaders is not comparable to the 1D cores of current Nvidia GPUs. The tessellation performance should be improved (like the desktop 6800 series) with the new cards. The stream processors can be used with DirectX 11, OpenGL 4.1, DirectCompute 11 and OpenCL. With the later two the cores can also be used for general computations like transcoding videos.

The 3D performance of the faster GDDR5 version should be slightly below the Radeon HD 6630M, the DDR3 version is about 20 percent slower. Therefore, current games run (more or less) fluently in 1366x768 and medium-low details. Playing highly demanding games like Anno 2070, a further reduction of the settings may be necessary.

The new UVD3 video decoder supports the decoding of MPEG-4 AVC/H.264, VC-1, MPEG-2, Flash and now also Multi-View Codec (MVC) and MPEG-4 part 2 (DivX, xVid) HD videos on the graphics card.

Furthermore, the HD 7500M series integrates a HD audio controller to transmit HD audio (TrueHD or DTS Master Audio) over HDMI and DisplayPort (e.g. for Blu-Ray videos).

The AMD HD3D Technology offers support for Blu-Ray 3D and 3D displays (integrated and external). However, the solution is not as mature as Nvidias 3D Vision.

Thanks to Eyefinity the graphics chip is able to theoretically drive up to 5 monitors simultaneously. However, this only works if the laptop features enough DisplayPort outputs.

The power consumption of the chip should be similar to the Radeon HD 6630M and therefore suited for 15" laptops and up.
