The new "Zen 3" CPU complex die (CCD) comes with a radical redesign in the arrangement of CPU cores, putting all eight CPU cores of the CCD in a single CCX, sharing a large 32 MB L3 cache. This the total amount of L3 cache addressable by a CPU core, and significantly reduces latencies for multi-threaded workloads. The "Milan" multi-chip module has up to eight such CCDs talking to a centralized server I/O controller die (sIOD) over the Infinity Fabric interconnect.
