Siggraph 2016 - AMD has changed its entire professional graphics branding at Siggraph 2016, with Radeon Pro replacing the FirePro branding, bringing all of AMD's graphics cards under the Radeon umbrella under Radeon Technologies Group.
AMD has three new Radeon Pro WX professional graphics cards, with all of them powered by their new Polaris architecture. We have the Radeon Pro WX 4100, WX 5100 and the higher-end WX 7100 with AMD telling us that they will all be priced at under $1000, with the WX4100 and WX5100 being priced "well below" $1000. What does WX stand for? Workstation experience, which makes sense, and makes things easier to discern between Radeon RX (consumer graphics) and Radeon Pro WX (workstation graphics).
The traditional workstation industry is who AMD are targeting with the Radeon Pro WX series graphics cards, as the WX series will have companies like Dell or HP that will have specific requirements in the way of power use, or clock speeds so that their workstations will last for years and years
