Considering the form factor of dual CPU sockets, that’s 128 cores. (virtual cores / hyper threading) could increase that to 256vCores. At that density, you’d need ~2TB of memory to get the most out of that high a count, not to mention other components like the bus architecture and networking. Considering power,heat, etc… 64 cores is a good stopping point.
