AMD 400 Series Due out this Summer will be Polaris 10 and 11 and New Chips from top to bottom, No Rebrands.

Top tier will get GDDR5x, Bottom Tier GDDR5.

HBM2 Due Out Next year, followed by NGM1 in 2018.

Depending on specs and Price, even sans HBM2, a 480/490X might be my target once prices come down, and in 2 Ywars jump to the NGM Cards.
