AMD Radeon HD 6750M

AMD Radeon HD 6750M

The AMD Radeon HD 6750M (also known as ATI Mobility Radeon HD 6750 is a fast middle-class graphics card for laptops. It supports DirectX11, is the immediate successor of the HD 5750M and features higher clock rates, 80 more shaders, Eyefinity+ and the new UVD3 video decoder. However, it is still produced in 40nm and is based on the same Whister core as the 6700M and 6600M series. First details also suggest that the HD 6750M is a 6650M with GDDR5 memory.

The 480 Stream processors are still based on the "old" 5D architecture similar to the 5000 series. Therefore, the number of shaders is not directly comparable to the 1D cores of current Nvidia GPUs. The Tessellation performance should be improved (like the desktop 6800 series) over the previous Radeon generation with the new 6700M cards. The Stream processors can be used with DirectX 11, OpenGL 4.1, DirectCompute 11 and OpenCL. The latter two features enable the Stream processors to be used for more general computations such as video transcoding.

The 3D performance of the 6750M should be similar to the older Radeon HD 5770M due to the large amount of shaders. Therefore, current and demanding games should run fluently in 1366x768 and medium to high details. Less demanding games, such as Sims 3 or Fifa 11, should run well in high details and resolutions.

The 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 an HD audio controller to transmit HD Audio (TrueHD or DTS Master Audio) over HDMI and DisplayPort (e.g., Blu-Ray videos).

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

Thanks to Eyefinity, the AMD 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 6750M chip should be similar to the Mobility Radeon HD 5770 and is therefore suited for 15" or larger laptops.
