The 3D performance of the faster GDDR5 version should be slightly below the Radeon HD 6630M, the DDR3 version is about 20 percent slower. With the later two the cores can also be used for general computations like transcoding videos. 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. The power consumption of the chip should be similar to the Mobility Radeon HD 5770 and therefore suited for 15" laptops and up.ĪMD Radeon HD 7570M ► remove from comparison However, this only works if the laptop features enough DisplayPort outputs. Thanks to Eyefinity the graphics chip is able to theoretically drive up to 5 monitors simultaneously. However, the solution is not as mature as Nvidias 3D Vision. The AMD HD3D Technology offers support for Blu-Ray 3D and 3D displays (integrated and external).

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.įurthermore, the HD 7500M series integrates a HD audio controller to transmit HD Audio (TrueHD or DTS Master Audio) over HDMI and DisplayPort (e.g. The 3D performance should be similar to the Radeon HD 6650M (see for gaming benchmarks) and therefore demanding games like Anno 2070 should only run in low to medium settings fluently. 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. The 480 Stream processors are still based on the 5D architecture similar to the 5000 series. The fast GDDR5 memory and the cut in half memory bus should lead to a similar performance as the 6650M with 128 Bit DDR3 memory. It is basically a renamed Radeon HD 6650M with a 64 Bit memory bus and support for fast GDDR5 graphics memory. The AMD Radeon HD 7590M (sometimes also called AMD Mobility Radeon HD 7590) is a middle class graphics card for laptops in 2011. AMD Radeon HD 7590M ► remove from comparison
