although I am basing that on believing AMD will keep the best 3800's to use as 3850's (so they're pre-binned).
That's always been my logic, essentially the 8700K/8086K but in reverse. My belief is the new Ryzen 9 SKU is a 16c/32t affair with a boost of 4.9GHz, so your standard CPU is the 3800X. However AMD kick off their 50th anniversary celebrations with an industry-crushing 16c/32t CPU with a 5.1GHz boost called the 3850X (50 for the anniversary) and released as a limited edition. That way the super golden sample 8 core, 5.1GHz capable chiplets can be batched up (AMD would "only" need 100,000 of these for a limited 50,000 unit run) and sold over a couple of months, all the while the 8 core chiplets that didn't quite get to 5.1GHz are prepped for the standard 3800X.
Then when the anniversary allocation is done, the 3800X is released and the binning only need continue for 4.9GHz boost. Of course, you could still win the silicon lottery and get a 5GHz or 5.1GHz capable boost in that, but the sheen and bragging rights of the anniversary edition is limited. It's the same with the 8086K - before and after it existed you still had common 8700Ks hitting and surpassing the 8086K's clocks.
So yes, AMD will still have those 5.1GHz golden chiplets come up, but they're not being as painstaking with their binning process since the big PR exercise that is/was the 3850X is done and dusted. But then again, who knows. I think the concept of the 3850X being an anniversary edition is entirely of my own fevered mind, simply because I can't see AMD explicitly and continually binning 8 core chiplets for the 5.1GHz boost for it to be an actual SKU. Made more sense in my mind to do a short run - it's the binning that's the limited run, not the production of the 16c/32t CPU.
