In addition, this generation of desktop processors still uses AM4 sockets, with up to 16 cores and 32 threads (two CCX / CCD modules). Although dual CCX/CCD modules are used, a single IOD module (I/O module) is still used for connection.

The CCX can run in single-threaded mode (1T) or dual-threaded mode (2T), so it can also have 16 cores and 16 threads.
