Zen 4 is the name for a CPU microarchitecture designed by AMD, released on September 27, 2022. It is the successor to Zen 3 and uses TSMC's N6 process for I/O dies, N5 process for CCDs, and N4 process for APUs.
Zen 4 powers Ryzen 7000 performance desktop processors (codenamed "Raphael"), Ryzen 8000G series mainstream desktop APUs (codenamed "Phoenix"), and Ryzen Threadripper 7000 series HEDT and workstation processors (codenamed "Storm Peak"). It is also used in extreme mobile processors (codenamed "Dragon Range"), thin & light mobile processors (codenamed "Phoenix" and "Hawk Point"), as well as EPYC 8004/9004 server processors (codenamed "Siena", "Genoa" and "Bergamo"). Zen 4 is the first microarchitecture whose chips (Ryzen 7000) use the AM5 motherboard socket.
