Zen3 on AM4! (probably, if it's still DDR4 there's no need to change the socket)
The decision to stick with SP3 for the server Zen 3 chips certainly implies it'll also be on AM4. The overall topology appears to stay pretty much the same - 8 core chiplets attached to an I/O die - so it'll be interesting to see how much it's a revised arch v. how much it's more of a refresh…
