IBM teaches mainframes to speak Arm with a dual-architecture 2nm chip
IBM unveiled a dual-architecture processor combining IBM Z and Arm instructions on a single core, aiming to bridge enterprise mainframes and the Arm software ecosystem.
IBM announced the development of a dual-architecture processor designed to run operating systems and applications on both IBM and Arm computing platforms in future IBM Z and LinuxONE systems. According to the company, this marks the first phase of a processor collaboration launched in April.
The new chip aims to let enterprise clients simultaneously run Arm-native Linux environments alongside z/OS and Linux on IBM Z. The hardware relies on a 2nm manufacturing process and features 11 high-performance cores running at frequencies above 5.7 GHz. It also includes built-in AI inference accelerators for transaction fraud detection, a dedicated data-processing unit for I/O acceleration, and a large cache architecture meant for intensive corporate workloads.
Rather than separating Arm and IBM cores, the architecture allows each processor core to execute both Arm and IBM Z or LinuxONE instructions concurrently while maintaining platform standards for availability, encryption, and hardware-level error recovery.
