amd zen 4

AMD Zen 4 is a microarchitecture developed by AMD for its Ryzen and EPYC processors, succeeding the Zen 3 architecture. Built using a 5-nanometer process (with an associated 6 nm I/O die), Zen 4 introduces improvements in performance per watt, higher clock speeds, expanded instruction sets (including AVX-512 support), and enhanced efficiency compared to earlier designs. It powers AMD’s Ryzen 7000 series desktop CPUs and fourth-generation EPYC server processors.
