The AMD EPYC 9534 processor is based on the Zen 4 Genoa microarchitecture that incorporates compute cores, memory controllers, I/O controllers, and security features into a single chip. Each processor includes 8 CPU dies known as Core Complex Dies (CCDs) with each CCD containing 8 Core Complexes (CCXs) yielding 64 cores per processor. All of the cores in a CCD feature are connected with a L3 cache. All CCDs are connected via an Infinity Fabric I/O Die.
To summarize, each processor should be thought of as having 8 smaller processors with each smaller processor having 8 cores on a shared L3 cache.
