If you have noticed the 'super teaser' from NVIDIA, and line that up against what is posted in the topic title, then it's safe to say that the SUPER graphics cards indeed will be a Turing refresh. The big news, however, is that Ampere is looking to arrive in 2020, which sounds like ages away but is next year. It'll be based on 7nm fabrication.

According to sources at Digitimes Samsung's 7-nanometer process should use EUV, making the chips easier to fab. It's not a new rumor, but the fact they have it confirmed does say a thing or two. Historically TSMC always has been NVIDIA's biggest partner, so the fact that the GPUs will be fabbed by Samsung is news as well. TSMC has been fighting on many nodes to keep up with demand though. 

That's all I can report about it, next year 7nm EUV NVIDIA Ampere GPUs.
