IBM Power 11 Versus Power 10: The 2026 Buying Decision
Power 11 is the current Power generation, but Power 10 remains central to installed estates and the acquisition market. How to frame the buying decision honestly.
Jump to the exact AS400 software question you want answered.
The decision is not just hardware generation
Power 11 is the current Power generation, but Power 10 remains central to installed estates and the acquisition market. The decision combines workload runway, software licensing, availability design, cost, support horizon, and risk.
Choose Power 11 for a strategic platform decision
Prioritize Power 11 when buying for a long service horizon, consolidating substantial workloads, designing new resilience, or expecting material growth.
Keep Power 10 in the evaluation when economics dominate
Power 10 can remain rational for known workloads, existing infrastructure, shorter planning horizons, or favorable acquisition economics. Withdrawal from marketing is not end of support. Verify model-level dates and maintenance coverage before ruling Power 10 out.
Compare the complete system, not just the chip
Model software licensing, activated cores, memory, storage, HMC, firmware, HA/DR, migration cost, and five-year total capacity. Power 11 is the default strategic platform. Power 10 remains a defensible tactical option when economics and support are documented, not assumed.
- Model licensing and activated-core costs across both platforms, not list price alone
- Confirm HA/DR and migration tooling compatibility before committing
- Verify support and maintenance coverage at the specific machine type-model level
