32 cores is a lot of cores in a CCD. Is there a there any smaller logical unit between a CCD and a core, or are you expected to wrangle 32 cores in your lowest NUMA level?

From what I've seen there is no intermediate unit. IMO this is good because it allows larger VMs that don't have to straddle L3s.

32 cores is only on the Zen 6c CCDs. There are 12 cores on the Zen 6 CCDs. Also not all 6c parts have the full 32 cores per CCD
