Power 10 vs Power 11
A practical comparison of Power 10 and Power 11 for teams deciding whether to expand Power 10, buy used, or move directly to the newer generation.
Power 11 does not automatically make Power 10 a bad platform. It changes the decision boundary. Power 10 can still be the better economic fit when the system is stable, the workload is predictable, and the expansion path is modest. Power 11 becomes more compelling when growth, support horizon, AI acceleration, memory bandwidth, or new-system financing dominate the decision.
Use this comparison as a planning filter, not as a replacement for a configured quote and compatibility review.

Model tier comparison: max cores and memory
| Tier | Power 10 Model | P10 Max Cores | P10 Max Memory | Power 11 Model | P11 Max Cores | P11 Max Memory | Core Increase |
|---|---|---|---|---|---|---|---|
| Entry | S1012 / S1014 | 8 | 1 TB | S1112 | 10 | 0.5 TB | +25% |
| Mainstream 2U | S1022 | 40 | 4 TB | S1122 | 60 | 4 TB | +50% |
| Scale-out 4U | S1024 | 48 | 8 TB | S1124 | 60 | 8 TB | +25% |
| Midrange | E1050 | 96 | 16 TB | E1150 | 120 | 16 TB | +25% |
| Enterprise | E1080 | 240 | 64 TB | E1180 | 256 | 64 TB | +7% |
What Else Changed
- Power 11 should be priced when long support horizon, new system financing, and new-generation architecture matter.
- Power 10 remains practical when the installed system is stable and expansion solves a defined bottleneck.
- IBM i tier exposure can outweigh the chassis difference in either direction.
