Arm has announced the Arm AGI CPU, its first proprietary silicon product in over 35 years, built on the Neoverse platform and designed for agentic AI workloads in data centers. The chip targets rack-scale efficiency, packing 272 cores per 1OU dual-node blade and up to 8,160 cores in a standard 36kW air-cooled rack, with a liquid-cooled 200kW Supermicro configuration supporting over 45,000 cores. Arm claims more than 2x performance per rack versus comparable x86 systems, driven by higher memory bandwidth and single-threaded efficiency of Neoverse V3 cores. Meta is the lead co-development partner, with additional launch partners including OpenAI, Cloudflare, Cerebras, SAP, and SK Telecom. Commercial systems are available from ASRockRack, Lenovo, and Supermicro. Arm also plans to contribute a reference server design to the Open Compute Project.
