AMD's CEO Lisa Su's interview, 24th of Jan:
Q17: For 7 nanometers, AMD has stated that the first product for this node is Vega and the focus is on machine learning. Some might feel that it is a bit odd for the first 7nm product to be on an existing GPU architecture and for the enterprise market. Do you have any comment?
LS: I think that we always think about this very systematically, as to how we bring out new process technology. In this case it made a lot of sense to bring Vega down to 7nm. Vega, as you know, is practically a brand-new architecture and it has only been out since August, so we believe Vega has legs. We have so many new features in Vega, such as adding some of the compute centric features – but the beauty of 7nm is density and the power. When you think about just how much compute horsepower you can put in the new technology, it made sense. We usually start with the GPU; the GPU is usually for us the first product in a technology. Graphics does have the capability for a lot of redundancy on it and so we feel like it’s a great utilization of the technology.
Q18: With GlobalFoundries 14nm, it was a licensed Samsung process, and 12nm is an advancement of that. 7nm is more of a pure GF design. Is there any change in the relationship as a result?
LS: So in 7nm, we will use both TSMC and GlobalFoundries. We are working closely with both foundry partners, and will have different product lines for each. I am very confident that the process technology will be stable and capable for what we’re trying to do.

Interview with GloFo manager:
Q15: With the first generation of 7nm, do you expect to be high volume production by the end of the year?
GP: By the end of the year or most likely in early 2019, with a couple of key partners. Our ASIC customers, of which there are quite a few, are also lead users of our 7nm process.

So, not totally impossible to have working 7nm chips that AMD could share with Sony today, but rather unlikely.
