Discover AMD’s EPYC 4005 server processors — explore Zen 5 upgrades delivering higher IPC, improved cache, AVX-512 support, and faster DDR5 memory for SMB servers and workstations.
AMD’s EPYC 4005 series server processors, codenamed Grado, are entry-level server chips designed for single-socket server and workstation deployments. Like its predecessor, EPYC 4004, the 4005 series supports multithreading and utilizes AMD’s AM5 socket. But whereas EPYC 4004 featured the Zen 4 CPU, the 4005 series steps up to the Zen 5 microarchitecture, offering a 16% generational improvement in instructions per cycle as well as improved cache hierarchy, higher maximum boost frequencies, and native execution of AVX-512 instructions. EPYC 4005 chips also support faster DDR5-5600 memory.
Like previous EPYC processors, the EPYC 4005 series features a chiplet structure; each device features up to two 4nm Zen 5 core complex dies and one 6nm I/O die manufactured by TSMC. With up to 16 Zen 5 CPUs per device, the 4005 primarily targets small and medium-sized business customers.
