IBM mainframe chip executes Arm and Z instruction sets on shared cores, switching in nanoseconds
↗
IBM announced at Hot Chips a mainframe processor whose cores natively execute both IBM's Z instruction set and Arm's, switching between them in nanoseconds.
Only one feed carries this, so corroboration is thin. If the claim holds, mixed Arm and Z workloads could run on the same core without separate silicon, which would change how mainframe deployments are architected. The practical implications for engineers depend on details not yet available.

IBM announced the chip at the Hot Chips conference, describing it as the most consequential mainframe architecture change in decades.
The processor's cores natively execute both IBM's Z instruction set and Arm's, switching between them in nanoseconds.
The chip will power the next generation of IBM mainframes.
