rPerf
Relative Performance, IBM's benchmark estimate for AIX and Linux workload throughput, analogous to CPW but for non-IBM i operating systems.
rPerf figures are IBM-published estimates derived from internal modeling and benchmarks, intended to compare processor options within the same Power generation. IBM publishes both single-threaded (rPerf ST) and multi-threaded SMT8 rPerf figures for many feature codes.
