Maybe Vega Nano might be the savior of that design... just like Fiji/Fury Nano... and they might save it along the mobile Vega in order to avoid rebadges while is preparing Navi.Ryzen refreshes on "12nm" are quite obvious, but Vega?
I can't quite see any point in throwing even more money at a non-salvageable design.
And makes me wonder...what will happen if Fury nano got a node shrink to 12 nm....
