It's not exactly clear how this model will be position. It could be a Radeon Pro WX series part, or perhaps a Frontier Edition prosumer card:
Right now, we can’t say if ‘Radeon Pro Vega’ series is meant to replace WX or Frontier series, but this sudden appearance does look suspicious, considering AMD only confirmed sampling 2 weeks ago. In other words, it is probably closer than we think.Other benchmark entries are found in the GFXBench and 3DMark databases, but keep in mind these are scores from prototypes with immature drivers.
