Coming this Fall to IBM Z, LinuxONE and Power, IBM Spyre Accelerator Enables Enterprises to Scale Generative and Agentic AI Workloads

ARMONK, N.Y., Oct. 7, 2025 /PRNewswire/ -- IBM (NYSE:IBM) today announced the upcoming general availability of the IBM Spyre Accelerator, an AI accelerator enabling low-latency inferencing to support generative and agentic AI use cases while prioritizing the security and resilience of core workloads. Earlier this year, IBM announced the Spyre Accelerator would be available in IBM z17, LinuxONE 5, and Power11 systems. Spyre will be generally available on October 28 for IBM z17 and LinuxONE 5 systems, and in early December for Power11 servers.

Today's IT landscape is changing from traditional logic workflows to agentic AI inferencing. AI agents require low-latency inference and real-time system responsiveness. IBM recognized the need for mainframes and servers to run AI models along with the most demanding enterprise workloads without compromising on throughput. To address this demand, clients need AI inferencing hardware that supports generative and agentic AI while maintaining the security and resilience of core data, transactions, and applications. The accelerator is also built to enable clients to keep mission-critical data on-prem to mitigate risk while addressing operational and energy efficiency.

The IBM Spyre Accelerator reflects the strength of IBM's research-to-product pipeline, combining breakthrough innovation from the IBM Research AI Hardware Center with enterprise-grade development from IBM Infrastructure. Initially introduced as a prototype chip, Spyre was refined through rapid iteration, including cluster deployments at IBM's Yorktown Heights campus, and with collaborators like the University at Albany's Center for Emerging Artificial Intelligence Systems. 

The IBM Research prototype has evolved into an enterprise-grade product for use in IBM Z, LinuxONE and Power systems. Today, the Spyre Accelerator is a commercial system-on-a-chip with 32 individual accelerator cores and 25.6 billion transistors. Produced using 5nm node technology, each Spyre is mounted on a 75-watt PCIe card, which makes it possible to cluster up to 48 cards in an IBM Z or LinuxONE system or 16 cards in an IBM Power system to scale AI capabilities.
