It's NUMA, just like usual. The difference is the exact topology, and the real difference in latency (which changes the cost function of accessing from a different node).
- floatboth 7y agoThe CCXes aren't NUMA, they all have the same access to memory, no system would show multiple NUMA domains on a desktop Ryzen. Only Threadripper and EPYC are NUMA.
- TazeTSchnitzel 7y agoZen 2 drops the NUMA because of the single I/O die with memory controller right?
- floatboth 7y agoI can't find confirmation, but that would make sense, single-socket EPYC and TR with Zen2 should be UMA
- microcolonel 7y ago> Only Threadripper and EPYC are NUMA. Yeah, I meant this. I don't use Ryzen so I think of Zen as being Threadripper and EPYC.
