Power 11
IBM's 2025-generation Power processor and server family, spanning the entry S1112 through the flagship E1180, built around three pillars IBM calls Trusted, Autonomous, and Modern.
IBM Power11 is the successor generation to Power10, announced in July 2025. It introduces DDR5 DDIMM memory, on-chip Matrix Math Acceleration for AI workloads, higher Open Memory Interface (OMI) bandwidth, and a requirement for HMC v11 management. Seven models are currently shipping: S1112, S1122, S1124, L1122, L1124, E1150, and E1180.
