Well, we do know that AMD's naming./numbering scheme for Polaris does allow for hardware revisions. So maybe these will be sold as 465, 475, and 485.

I can see AMD launching xx5 revisions as they showed in that slide explaining the naming of the new cards. What I don't believe is the 50% improvement claimed by those sites.

Up to 15, maybe 20% by next year as the process gets more mature and refined could be, but a 50% improvement in only 4 months since the 480 launched? No way.
