AMD launched their new entry level workstation graphics card, the FirePro V3900, on February 7. With almost double the performance of it's predecessor, FirePro V3800, the card is available from select resellers for $119, $20 more than the V3800. AMD say "The AMD FirePro(TM) V3900 is the most powerful entry-level professional graphics card on the market today."

The V3900 has 480 Stream Processors with a 128-bit memory interface. There is 1 GB of DDR3 memory, with a bandwidth of almost 28.8 GB/s. A dual-link DVI port and DisplayPort 1.2 outputs allow for up to 6 monitors to be powered simultaneously. The standard card is one slot wide, and uses less than 50W, with a TDP of 75W. Some sources say the GPU core is the same as Turks (Radeon HD6800 series), but I have not seen evidence from AMD to say that.

Driver support includes DirectX 11, OpenGL 4.2 and OpenCL 1.1, meaning the V3900 is compatible with all modern, gpu accelerated software. The hardware interfaces is PCI-E 2.1 x16, although it will only use a fraction of the bandwidth that offers.

The table above shows that the GPU clock speed is unchanged from the V3800. However, a 20% increase in shader count leads to a 20% increase in theoretical maximum computer performance. Combining that with double the memory and double the bandwidth, AMD are claiming up to 95% increase in performance for some applications (primarily memory intensive tasks). Improved OpenGL support adds extra application compatibility, and of course the upgrade to DisplayPort 1.2 will benefit some applications.

The 20% price increase over the V3800 looks like a nice price tag for all the extra performance properly optimized code will give. Internal AMD benchmarks indicate that the FirePro V3900 is on average 74% faster than the higher priced NVidia Quadro 400, equipped with 512 MB memory.
