IBM Unveils Dual-Architecture Mainframe Processor

IBM is planning to release a revolutionary mainframe processor that can run both Arm and Z workloads on the same cores. This dual-architecture chip will allow organizations to integrate AI into their core business operations by expanding their infrastructure options.

The new processor features 11 cores, running at 5.7GHz, with AI inference accelerators for in-transaction fraud detection, a dedicated data processing unit for I/O acceleration, and a 3.5GB cache architecture for demanding enterprise workloads.

This move marks a significant architectural advancement for IBM Z and LinuxONE, combining access to the fast-growing Arm software ecosystem with the qualities that have made IBM systems the foundation for businesses. Christian Jacobi, CTO and IBM Fellow, stated, 'This processor represents a significant architectural advancement... By bringing Arm natively to our platform, we're combining access to one of the industry's fastest-growing software ecosystems with the qualities that have made IBM systems the foundation for how businesses run today.'

Mohamed Awad, EVP, Cloud AI, Arm, noted, 'As AI scales, more of the computing landscape is converging on Arm.' He added that bringing Arm compute and its ecosystem to these platforms will extend momentum into mission-critical enterprise infrastructure, giving organizations greater choice in deploying AI.
