IBM is building a dual-architecture mainframe chip that will run Arm and Z software on the same cores
Hot Chips 2026: Intel Xeon 7 'Diamond Rapids' comes with up to 256 P-cores, 1.28 GB of last-level cache — next-gen 18A-P CPU also brings AVX 10.2 and uses UCIe-S instead of EMIB
Hot Chips 2026: IBM's first dual-ISA core natively executes ARM and z/Architecture in the same core; all cores run at 5.7 GHz base frequency — next-gen mainframe AI processor is built on 2nm node with 11 cores
