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 intended to compare processor options within the same Power generation. IBM's Power11 launch materials cite up to 37% more rPerf per watt versus Power10, a key efficiency data point behind this site's generational comparisons.
