I gave my reasons for why I have trouble understanding the release another CPU before 7nm.
1. Lack much tangible information on a processor to be released before 7nm.
2. It goes against their efficiency model being that 8 core parts are used to make up Server parts, and HEDT parts, and defects fall into R5 and R3 lines.
3. Their road map says 7nm Epyc 2nd half 2018!
4. They changed the GPU roadmap from Vega 20 to 7nm Navi for 2018!

And the public and private roadmaps contradict what you say!
First Zen on 14nm on 2017. Then Zen on 14nm+ on 2018. Then Zen2 on 7nm on 2019.
Juanrga I know you like to use leaked roadmaps like the one you keep showing off, but let's just stick to the latest official releases from Analyst day! The dates on the roadmaps are not exact time tables for launches, which you have pointed out in the past. I don't give an exact time tables either. I give possible time tables not that I believe it's going to happen, but a possibility even if it is a slim one. I would assume as well that 14+ would be a filler if they couldn't get to 7nm, because it doesn't make sense with their efficiency model, which uses 8 core parts to make server CPUs. Also, TSMC could potentially be an options as well.
Zen there are no release dates on the roadmaps for 2018-2019, and for 2017 14nm and 14+.
The roadmap I have given is the roadmap for -OEMs/integrators, and so on. The one you give is a roadmap for investors. The roadmap for investors is spare in details, because AMD want to get their money. That is why the roadmap for investors doesn't give detailed product list neither dates.
Same happened with the investors roadmaps for Zen. AMD got investors and press believing that Zen would launch in 2016. I said that Zen was a 2017 launch. And during an entire year people insulted me and called me names because I didn't buy the hype. Finally Zen was launched in 2017. I was right.
I guess the same will happen with Zen2.

"As it is, AMD has to pay GLOBALFOUNDRIES for its wafer orders that go to other silicon producers (in this case, TSMC), in a quarterly basis since the beginning of 2017, based on the volume of certain wafers purchased from another wafer foundry. In addition, AMD has annual wafer purchase targets from 2016 through the end of 2020, fixed wafer prices for 2016, and a framework for yearly wafer pricing in this amendment, so the company is still bleeding money to GLOBALFOUNDRIES. However, AMD is making the correct decision in this instance, I'd wager, considering GLOBALFOUNDRIES' known difficulties in delivering their process nodes absent of quirks."

"In addition to modifying certain terms of the WSA applicable to AMD's microprocessor, graphics processor, and semi-custom products, the amendment:
Covers a 5-year period, spanning from calendar year 2016 through 2020;
Establishes a comprehensive framework for technology collaboration between AMD and GF for the 7nm technology node, building on the success of the 14nm node;
Provides AMD with the flexibility to manufacture certain products with another wafer foundry;
Sets annual wafer purchase targets from 2016 through the end of 2020, fixed wafer prices for 2016, and a framework for yearly wafer pricing.
In partial consideration for these rights, AMD will:
Make a $100 million cash payment to GF, paid in installments beginning in Q4 2016 through Q3 2017.
Make quarterly payments to GF beginning in 2017 based on the volume of certain wafers purchased from another wafer foundry.
Grant to West Coast Hitech L.P., a wholly-owned subsidiary of the Mubadala Development Company PJSC, a warrant to purchase 75 million shares of AMD common stock at a purchase price of $5.98 per share. The warrant may be exercised in whole or in part prior to February 29, 2020. The warrant is only exercisable to the extent that Mubadala or its subsidiaries do not beneficially own, either directly or indirectly, an aggregate of more than 19.99 percent of AMD's outstanding capital stock after the exercise."

Don't get your point. First you tried to convince me that Glofo is different now and 7nm will be ready in 2018. But I expect 7nm in 2019. Now you change the argument by 180º and emphasize that AMD did pay GF for getting access to other foundries, because GF has a long record on underdelivering!
Unless GF cancel the 7nm node, AMD will not make orders in other foundries. It will be cheaper for AMD to delay products rather than pay twice: one time to GF for making orders in other foundries; other time to the other foundry.
