AMD FirePro M3900
The AMD FirePro M3900 is a laptop graphics card for entry level mobile workstations. It is based on the consumer AMD Radeon HD 6470M (Seymore-XT) and therefore features the UVD 3 video decoder. Compared to the Radeon consumer line, the FirePro offers certified drivers for professional 3D applications. Due to optimizations and some unlocked features, the performance using professional applications is highly improved.
The 120 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 theoretical performance is similar to the consumer counterpart, the Radeon HD 6470M. However, du to the professional drivers, games may run a bit slower. The 6470M is able to run modern games in low settings and resolutions fluently (see benchmarks on the HD 6470M page) and therefore the M3900 is also not really suited for gamers.
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 FirePro M3900 integrates a HD audio controller to transmit HD Audio (TrueHD or DTS Master Audio) over HDMI and DisplayPort (e.g. für 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 HD 6470M graphics chip is able to theoretically drive up to 4 monitors simultaneously. Therefore, the support on the M3900 should be similar. However, this only works if the laptop features enough DisplayPort outputs.
The power consumption of the chip lies at about 20 Watt and is therefore suited for 13" laptops and up.
