Zen is a single design for the entire stack. Its the entire desktop and enterprise market is based entirely on binning practices. The absolute BEST binned dies go into all models of EPYC, then the 2nd best go into TR, third best into R7s, fourth best into R5s, fifth best into R3s. All dead dies act as balancers for the TR and EPYC socket because of the way IF works.
If AMD is already sampling 7nm EPYC to to their most trusted customers RIGHT NOW, it means that Q1 we'll see them talking about the Zen2 architecture changes and perf uplifts in IPC, cache optimizations, etc. Q2 we'll see them start talking about consumer release and latest Q2 end to early into Q3 we'd see Zen2 formally release into the consumer market.
There's no fucking way AMD is going to let Intel carve out market share with the 9900X/K series chips when they're 14nm+++++++++ nuclear reactors.
AMD is in the absolute best position to completely slaughter Intel, and they're going to capitalize on it. That's the beauty of making a CCX based single-die design that can scale up to the entire stack courtesy of the Infinity Fabric.
R9 looks fake though, even if the in the deepest of my heart I want it to be true.
