Wait, does a single CPU chip have numa within it now, or are you only talking about multi-socket machines?

Modern AMD processors are basically a bunch of smaller processors (chiplets) glued together with an interconnect. So yes single chip nodes can have many numa zones.

That was Zen 1, the later ones don't have per chiplet memory controllers, it's all on the single IO die, and they are not NUMA for a single socket.

Single chips do.
