The FirePro M3900 was a professional graphics card by AMD, launched in October 2010. Built on the 40 nm process, and based on the Seymour graphics processor, in its Seymour GL variant, the card supports DirectX 11.2. The Seymour graphics processor is a relatively small chip with a die area of only 67 mm² and 370 million transistors. It features 160 shading units, 8 texture mapping units and 4 ROPs. AMD has placed 1,024 MB GDDR3 memory on the card, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 750 MHz, memory is running at 900 MHz.
Its power draw is rated at 20 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. FirePro M3900 is connected to the rest of the system using a PCI-Express 2.0 x16 interface.
