Hot Hardware published a review on the AMD Announces Polaris-Based Radeon Pro WX And Radeon Pro SSG With Up To 1TB Of Memory A quote from the article:

AMD took the wraps off its latest pro graphics solutions at Siggraph today, and announced three new professional graphics cards in the new Polaris-based Radeon Pro WX Series. The Radeon Pro WX 4100 is the entry-level model with a half-height design for use in small form-factor workstations. The Radeon Pro WX 5100 is the middle child, while the Radeon Pro WX 7100 is AMD's current top-end WX model.

None of these cards will be giving the new NVIDIA Quadro P6000 a run for its money in terms of performance, but they don't have to. The Quadro card will no doubt costs thousands of dollars, while the Radeon Pro WX 7100 will eek in at just under $1,000. The Radeon Pro WX 5100 and 4100 will slot in somewhat below that mark.
