Yes. Raven Ridge in late q4 2017, Pinnacle Ridge in q1 2018, Vega 11 in q1 2018 and a Vega 10 refresh in mid 2018 are likely to use 14nm+.I'll require a source on that, that would imply AMD's 14nm+ "refreshes" (Vega and Zen) are going to be quite a bit different than I expected it.
Unless AMD is using the "14nm+" they used for Polaris 20.
EDIT: Now that I think about it, Raven Ridge might be using "14nm+" as well considering how late into the year it is.
I don't think he is basing that on an official statement from AMD or SS.... and he is wrong about 14nmLPE because AMD didn't license it. And I remember reading someone posting the rx580 description talking about using a third generation 14nm FinFet process which probably is 14nmLPC.
Many thanks for the round-up. So we'll see another 14nm refresh from GloFo in the end of 2017 / early 2018 which should be better than their first revision early this year. I hope it will give AMD's much needed clock boost to all of their products.
Yes, but it makes more sense. Su has said tape out Q4 2017 for Zen 2 7nm and suggested as early as Q3 2018. Even if we look to Q4 2018-Q1 2019, that is a short time. Glofo and AMD have worked on 14nm since 2015 and have already themselves suggested 14nm+ products in Q4 2017 and Q1 2018. If the 14nm+ brings further power reduction capabilities, it makes sense to switch, thereby being more competitive with Intel's offerings.
Because RX5xx is using refined 14LPP, that's why there's not much gain from the Polaris refresh. GloFo somehow made a mess in adopting Samsung's LPP, they had to refine it along the way.
So that's it then. However there must be some changes on it, at least an step B2 or something that fixes the bugs present on Ryzen.
Most things called "bugs" are not bugs, rather software is not yet optimized on it.
Raven Ridge being 1x CCX will be only the second Zeppelin die in existence, the first being a die that was primarily designed for use in Naples/Epyc and then scaled down for mainstream consumer market. The Raven Ridge die will be optimized for mobile use, at least all server/MCM specific I/O with no use in an APU will be taken out. (I guess this is more a question of definition whether Zen+ will contain changes to the microarchiteture itself or just the uncore akin to e.g. Skylake-X. I expect only the latter which would explain why there won't be a Zen+ for Epyc etc.)

I don't think they'll use an improved version. I'm saying that you would use the same process and that the mobile will be one of the first on that process. How hard is it for you to understand that?
In absolute terms you know nothing about the process Raven Ridge is built on and neither do I. What we do know is Zen is going to use 14nm+ . Given the late Q4 2017 launch of Raven Ridge notebook I am speculating it is the first one to use 14nm+ followed by desktop Raven Ridge, Pinnacle Ridge and finally Threadripper 2018. You can disagree with that. I won't argue further on this.
Pretty sure this is what you said previously, derisively, which insinuates what you accuse me of: "If you think they'll use an improved version of their process for the socketed low volume desktop version of Raven Ridge, and thus having two different versions of Raven Ridge right out of the gate, you have completely lost your mind."
