What do we know about behavior and production and changes about Zen2 steppings? I have a 0 stepping 3700X. But have never seen another one.
I’ve seen B0.
AFAIK B0 is usually AMD release silicon, I've never seen any upgraded stepping on Zen2 it should still be on release stepping. We will see if the XT:s change that, but I don't think so. From the few leaks, all have been B0.
If you have a 0 without B you may have a engineering sample.
