Everything I've been reading has been that 7nm has been having excellent yields and chiplets do bring their own costs. Lisa Su (AMD CEO) indicated in an interview a while back that there is a price floor at which chiplets make sense. Another thing to consider is that most of the chiplets used in the consumer parts could be considered rejects from Epyc. (i.e. they need to make a lot of relative duds to get the small number of 'golden samples' they use in their server chips)
