    The $64,000 question is, will that be passed on to consumers?

    Thanks @sonic for pointing this. It made me investigate and I found some technical details here:

    https://www.servethehome.com/amd-epyc-infinity-fabric-update-mcm-cost-savings/
    https://www.servethehome.com/amd-epyc-7000-series-architecture-overview-non-ce-ee-majors/

    They seem to save production costs versus monolithic design because if a big monolithic die production fails, then all the die is lost vs only the small die in MCM design, thus the higher yield of production.
    Also, the MCM design is more modular, and a same small die can be used for diffferent chips (epic, threadripper, ...) which makes even more cost saving.

    For now, only the prosumer or enthusiast consumer market is seeing this passed on to high-end desktop processors with 12 cores (!) and up. As far as benefits, ThreadRipper costs $200 to $1000 less ($799 and $999 for the 12-core and 16-core models) while offering higher or equal performance than its Intel Core i9 competition, which starts at $999 (i9-7900X with 10 cores) and can cost as much as $1999 (i9-7980XE with 18 cores). However, if the competition really heats up between Intel and AMD next year, we may see these designs drop down to $500-$700 territory. As for tablets, though, this design paradigm probably will have null effect on the single die dual core and quad core processors that will continue to make up the totality of this market.

    More insight and headline news on Zen 2 and Raven Ridge, direct on the floor at PAX West:

    Per the interview, Ryzen was a "worse case scenario" meaning AMD has much better things in store in Raven Ridge and Zen 2 and they are holding their cards close to their chest.

    <<...Per the interview, Ryzen was a "worse case scenario" meaning AMD has much better things in store...>>

    ...Dumb way to put it, though. Ryzen was a conservative case, not a worst case. Words convey important perceptions...!

    I agree the word "worst" alone could perhaps come across as unfortunate and dire. However, conservative seems a bit too stuffy, especially when many consumers have lost all patience listening to Intel using overly formal marketing fluff for so long. In addition, consider the audience where this interview was held: PAX West. This was not a press conference to the best and brightest technical wizards in journalism. These are hardcore gamers at a game conference who want to hear the straight up facts free of any malarkey or political correctness. The point made in the video was for a worst case result, first generation Ryzen was a job changing product that shook up the market and this is only the beginning. It is like in basketball: an league-leading team was off their game (several benched for fouls; several star players recouping from injuries) but they still won the match. At their next game, they are bound to mop the floor since the worst is behind them.

    One of the major challenges surrounding AMD's Zen 1 design is the low voltage wall in GlobalFoundaries' 14-nanometer manufacturing process, which results in Ryzen being unable to be sold in stock configurations above 4 GHz. Thankfully, Zen 2 will be using GlobalFoundaries' next-generation 7-nanometer process, which is touted as supporting stable 5 GHz clock operation.
