Sadly AMD has been not-telling-the-truth in their slides for some time... More or less all newish APU/GPU launch slide decks contained features which were never really functional. Historically, the most flawed features were DVFS related (notably Jaguar, Kaveri and Polaris). Vega just took it to a new level.
When Tonga felt like a dull stop-gap product, Fiji like a strange engineering sample, I don't know how to categorize Vega even 6 months after the release.
