No. RX 480 has no chance. AMD is doomed. They will never release anything faster, they just don't have the R&D resources to make a seriously powerful GPU anymore. I don't even know how they could afford to do R&D on HBM and HBM2 at all. It's probably just a lie, Vega does not exist.
I heard RTG will be sold off soon.
I also heard gamers like paying extra for reference design cards, I thought that cannot be true, people cannot be that stupid to pay extra for nothing... but it's true. So if that's true, then AMD is doomed.
