MagyarAMD Radeon HD 6730M
The AMD Radeon HD 6730M (sometimes also called ATI Mobility Radeon HD 6730 or similar) is a fast middle class graphics card for laptops. It supports DirectX11, is the successor of the HD 5730, and features higher clock rates, 80 more shaders, Eyefinity+ and the new UVD3 video decoder. However, it is still produced in 40nm and based on the same Whister chip as the whole 6700M and 6600M series. First informations also suggest, that the HD 6730M is a 6770M with slow DDR3 memory.
The 480 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 should be a bit above the old Radeon HD 5730 due to the larger amount of shaders. Therefore, current and demanding games should run fluently in 1366x768 and medium to high details. Less demanding games like Sims 3 or Fifa 11 should run in high details and resolutions.
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 6700M 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 Mobility Radeon HD 5730 and therefore suited for 15" laptops and up.
