AMD Radeon HD 6630M vs AMD Radeon HD 6650M

AMD Radeon HD 6630M

The AMD Radeon HD 6630M (sometimes also called ATI Mobility Radeon HD 6630 or similar) is a  middle class graphics card for laptops. It supports DirectX11 and is the successor of the low clocked HD 5650 chips (low power). Compared to the HD 5650 it offers 80 more shader, Eyefinity+ and the new UVD3 video decoder.

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 is similar to the older Radeon HD 5650 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. Detailed gaming benchmarks can be found below.

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 6600M 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 low clocked Mobility Radeon HD 5650 chips and therefore suited for 14" laptops and up.

AMD Radeon HD 6650M

The AMD Radeon HD 6650M (sometimes also called ATI Mobility Radeon HD 6650 or similar) is a fast middle class graphics card for laptops. It supports DirectX11, is the successor of the HD 5650, 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 6650M is a 6750M with DDR3 memory.
