The new AMD FirePro W4300 professional graphics card will be a part of AMD's entry-level FirePro lineup, targeting SFF (Small Form Factor) segment which is also the largest growing segment in the workstation market, aimed to be used for entry-level CAD/CAM work.
As noted, the AMD FirePro W4300 is based on AMD's Bonaire GPU and packs 768 Stream Processors, 16 ROPs and 4GB of GDDR5 memory paired up with a 128-bit memory interface. It works at 930MHz for the GPU and 6GHz for 4GB of GDDR5 memory. This makes the FirePro W4300 exactly the same as the earlier available FirePro W5100, based on the same GPU and the same specifications. Unlike the AMD FirePro W5100, the FirePro W4300 has a lower 50W TDP and is based on a low-profile form-factor. Accooring to AMD, the lower TPD is achieved with improved PowerTune technology so we are not clear if there is any performance difference between these two graphics cards.
The new FirePro W4300 also comes with support for AMD Eyefinity multi-display technology and features four Mini-DisplayPort 1.2a outputs.
The AMD FirePro W4300 will launch soon with an MSRP of US $379. Nvidia has been a king in this market for quite some time and currently the direct competition of the FirePro W4300 is Nvidia's GM107-based low-profile Quadro K1200. While the Nvidia Quadro K1200 has a lower 45W TDP, AMD FirePro W4300 should provide much better performance in those professional applications.
