IBM and Arm build 2nm chip that runs both Arm and IBM mainframe ISAs

GG Brief Editorial Desk · AI-assisted, source attributed

IBM and Arm have developed a single chip that implements both Arm and IBM instruction set architectures, enabling it to run Arm-based Linux environments and IBM z/OS software natively. The chip is fabricated on a 2 nm node, contains 11 high-performance cores running above 5.7 GHz, and includes AI inference accelerators plus an on-chip data-processing unit for I/O. Targeted at enterprise cloud and AI infrastructure, the design removes the need for instruction emulation and lets customers consolidate Arm and IBM workloads on the same hardware.

• Chip supports both Arm and IBM ISAs natively, allowing Arm Linux and IBM z/OS software to run without instruction emulation.
• Manufactured on a 2 nm process with 11 high-performance cores operating above 5.7 GHz.
• Includes AI inference accelerators and an on-chip data-processing unit (DPU) for I/O acceleration.
• Aimed at enterprise cloud and AI infrastructure and positioned to leverage Arm’s large developer and customer ecosystem (over 22 million developers, including companies such as Nvidia, Microsoft and Google).
