The EPYC 9256 is a 24-core, 48-thread model of AMD's 6th Gen EPYC 9006 series (Zen 6, code-named Venice), announced on July 23, 2026. Built for the SP8 platform, which AMD positions for balanced, power-efficient servers, it runs at 2.85 GHz base and up to 4.5 GHz boost with 96 MB of L3 cache and supports one- or two-socket systems. It combines a moderate core count with eight channels of DDR5 RDIMM or MRDIMM memory and 128 lanes of PCIe 6.0, a good fit for general-purpose and I/O-heavy servers. CPU power defaults to 190 W and is configurable from 130 W to 220 W.

- Notes
- A server processor, typically deployed with Windows Server or enterprise Linux. The EPYC 9006 series is not named on Microsoft's Windows 11 24H2 or 25H2 supported-processor lists, and it launched after Windows 10 support ended. Mainstream Linux distributions run on it; a recent kernel is recommended for full Zen 6 support.
