The CPW rating describes this complete configuration. Use the partition plan and licensed IBM i cores to turn that system rating into a quote.
S1024 EPGM 24-core CPW per core
CPW per core is the CPW rating divided by the cores that deliver it. IBM i is licensed by core, so this calculation helps compare the amount of IBM i work available from each licensed core. Use total CPW to size the full workload.
| Configuration | Cores counted | CPW | CPW per core |
|---|---|---|---|
| EPGM 24-core | All 24 cores | 585,100 | 24,379 |
S1024 EPGM 24-core AIX performance (rPerf)
rPerf is the relative performance rating for AIX workloads. ST is single-thread. SMT2, SMT4, and SMT8 show the rating with two, four, or eight hardware threads running on each core.
| Configuration | ST | SMT2 | SMT4 | SMT8 |
|---|---|---|---|---|
| EPGM 24-core | 220.1 | 438 | 629.1 | 810.6 |
