S1012 EPG3 1-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 number shows how much IBM i work you get from each licensed core. Use it to compare processors, and use total CPW to size the whole workload.
| Configuration | Cores counted | CPW | CPW per core |
|---|---|---|---|
| EPG3 1-core | One core | 27,825 | 27,825 |
S1012 EPG3 1-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.
EPG3 runs IBM i only, so it has no AIX rating.
S1012 memory and storage
| Specification | Configuration |
|---|---|
| Maximum memory | 64 GB |
| ISDIMM features | EMBN 32 GB (2 x 16 GB); EMBW 64 GB (2 x 32 GB); EMBY 128 GB (2 x 64 GB); 3200 MHz DDR4 |
| Slots | Four ISDIMM slots; industry-standard DIMMs supported |
| Bandwidth | 102 GBps peak per socket |

Compare S1012 EPG3 1-core with other S1012 configurations
EPG3 is the only S1012 limited to IBM i and 20 users. EPG7 gives four cores, 111,300 CPW, and no user limit in the same P05 tier.
| Configuration | Cores | Sockets | Clock GHz | IBM i tier | CPW | CPW per core | rPerf SMT8 |
|---|---|---|---|---|---|---|---|
| EPG3 1-core (this page) | 1 | 1 | 3.0 to 3.9 | P05 | 27,825 | 27,825 | Not listed |
| EPG7 4-core | 4 | 1 | 3.0 to 3.9 | P05 | 111,300 | 27,825 | 130.4 |
| EPGZ 8-core | 8 | 1 | 3.0 to 3.9 | P10 | 222,600 | 27,825 | 234.1 |
The Power 11 S1112 keeps the compact IBM i role. Its EJMT 4-core reaches 117,300 CPW in P05.
