[QUOTE="Zucker2k, post: 39855216, member: 189543" AMD's ONLY advantage at this time is TSMC's 7nm[/QUOTE]
Well, that's just not true- being the first to have a functioning chiplet design has all sorts of advantages. It's probably the biggest factor allowing AMD to have Zen2 this year, Zen3 next year, and Zen4 the year after.
It means that they can design new CPU chiplets, push them into (affordable) production earlier than a large monolithic design, and lets them shuffle around CPU, GPU and IO dies as needed for new products.
Being ahead on process is icing on the cake; they'd be competitive without that advantage, but they are indeed fortunate that it puts them comfortably in the lead (for now).
