CPW
Commercial Processing Workload, IBM's relative-performance benchmark for IBM i systems, used to compare processor options across Power generations.
CPW figures let you compare a Power8 system's actual IBM i throughput against a candidate Power9, Power10, or Power11 replacement more accurately than core count alone. CPW figures should only be compared within the same benchmark family and IBM i release.
