![]() The stream processors can be used with DirectX 11, OpenGL 4.1, DirectCompute 11 and OpenCL. The tessellation performance should be improved (like the desktop 6800 series) with the new cards. Therefore, the number of shaders is not comparable to the 1D cores of current Nvidia GPUs. The 400 stream processors should be still based on the "old" 5D architecture similar to the 5000 series. 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 AMD Radeon HD 7570M (sometimes also called AMD Mobility Radeon HD 7570) is a DirectX11 middle class graphics card for laptops. AMD Radeon HD 7570M ► remove from comparison ![]()
