IBM Unveils 2nm Processor Built for Dual-Architecture Computing
The 2-nanometer chip has 11 cores and on-chip AI accelerators, and IBM says it will let Arm-native Linux run alongside z/OS workloads.
- On Monday at the annual Hot Chips conference, IBM announced its first dual-architecture mainframe processor, enabling enterprises to execute IBM Z and Arm-native workloads concurrently on future systems.
- Tina Tarquinio, chief product officer for IBM Z and LinuxONE, said the move supports the Arm software ecosystem, which includes more than 22 million developers and increasingly defines modern AI infrastructure.
- Christian Jacobi, chief technology officer and IBM Fellow at IBM Systems Development, explained the chip's 11 cores dynamically switch between architectures in nanoseconds, resulting in effectively zero performance penalty.
- Organizations can now deploy large language models and agentic workflows directly alongside mission-critical data, extending the mainframe's relevance in an AI-driven era.
- IBM holds to a roughly three-year product cadence, pointing to a launch for this new processor around 2028 in the successor to the z17 mainframe.

BizTocIBM announces chip that natively executes Arm and Z instructions concurrently
IBM has revealed it is working on a chip with processor cores that can execute instructions for its own mainframe chips and for the Arm architecture – and for the LinuxONE architecture too for good measure. Big Blue says the unnamed chip will be built on a two-nanometer technology node, include 11 high-performance cores operating at more than 5.7 GHz, plus AI inference accelerators for in-transaction fraud detection, a dedicated on-chip data pro…
IBM is building a dual-architecture mainframe chip that will run Arm and Z software on the same cores
The processor was showcased at Hot Chips 2026 and is expected to use 11 IBM Z cores built on a 2-nanometer process. IBM said the cores will operate above 5.7 GHz and support native execution of both z/Architecture and AArch64 instructions.Read Entire Article
IBM unveils 2nm processor built for dual-architecture computing
IBM has unveiled a 2-nanometer processor designed to bring Arm computing directly into its mainframe systems, allowing enterprises to run Arm-native Linux alongside existing IBM workloads. Announced at the Hot Chips conference, the processor is the first dual-architecture mainframe chip from IBM and is being developed for future IBM Z and LinuxONE systems. It is the first hardware milestone from IBM’s collaboration with Arm, established in April…
