New AMD roadmap shows Vega and Navi Architectures
While the Polaris GPU architecture is to be released this year, two new architecture (or product series) code-names have surfaced in a roadmap shown in an AMD presentation, Vega and Navi.
It seems that after Polaris in 2017 VEGA will make an appearance, the name is tagged with HBM2 meaning that HBM2 likely will not make it onto Polaris. Vega is the brightest star in the constellation Lyra, the fifth brightest star in the night sky and the second brightest star in the northern celestial hemisphere, after Arcturus. Next in line in the 2018 timeframe we see Navi with the two keywords being scalability and Nextgen memory.
The slide is plotted in years/time against perf per watt, so you will notice that the perf/watt ratio almost makes a 2x step every new release. It will be interesting to see how ling AMD stays at 15nm, 7nm is obviously the next step in fabbing, that technology is due for release in 2019/2020.

Looks like HBM2 is not quite ready in general.

I wonder if it's HBM2 not being ready, or big die sizes worthy of HBM2 not being ready.
I mean they showed Polaris 10 running Hitman at roughly the same performance as a 980Ti. And it's not like slapping HBM2 on a 980Ti is going to do much other then increase cost and slightly reduce power. If Polaris 10 is AMD's largest card for this year, they can easily just throw GDDR5x on it instead of HBM and hit nearly every performance target while slightly reducing power/cost.
I'm sure Nvidia is in the same boat, hence why rumors about the GP104 using GDD5x as well.
Why go through all the pain of using an interposer with HBM2 if the the manufacturing is limiting you to midsized chips?

So, based on the release date and the use of HBM2, Vega would be the new fury?

Define "fury"
Polaris 10 has roughly the same performance as Fury and probably has HBM1 on it. So I'd argue that Polaris 10 is the new Fury.
But if you mean "Fury" as in card that's pushing technology, then yeah, Vega probably first cards to use HBM2.

Will GDDR5X even be available in time and in volume?
EDIT: was referring to Polaris
I read yesterday on the topic of the Geforce 1080 rumor that the company responsible for GDDR5X would be in mass-production in spring 2016.
