AMD CEO Lisa Su confirmed yesterday that the company will be taping out 7nm products later this year. Su was at the 45th annual J.P. Morgan Global Technology, Media and Telecom Conference to provide additional detail into its long-term roadmap that it had disclosed earlier last week at its Financial Analyst Day.

so that means vega 2 and Navi  early
 
Like i said 7nm is early  Nvidia could use it
the issue here is HBM2 and GDDR6 which are late, lower spec'd and in low quantities
