Power7 → Power8 → Power9 → Power10 → Power11 Migration Comparison
A structured, tier-by-tier comparison showing what replaces your IBM Power7 system across all four generations that followed it: Power8, Power9, Power10, and Power11.
There is no direct Power7-to-Power11 in-place upgrade. Every migration off Power7 is a hardware refresh, and it is the widest generational gap covered in this portfolio. The table below maps each Power7 tier through its Power8 and Power9 predecessors to its Power10 and Power11 successors, so you can see the full four-generation chain in one place.
IBM i 7.6, the current-generation IBM i release, only runs on Power10 (firmware FW1060 or later) or Power11 hardware. Power9 tops out at IBM i 7.5, and Power8 tops out at IBM i 7.4 ... neither reaches the current release. If you want hardware that supports IBM i 7.6 without a second refresh in a few years, Power10 or Power11 is the more direct move from Power7.
Power7 model tier to current-generation replacement chain
Power8, Power9, and Power10 are shown as the intermediate steps IBM actually shipped between Power7 and the current Power11 generation. IBM i 7.6, the current release, requires Power10 (firmware FW1060+) or Power11 ... Power9 tops out at IBM i 7.5 and Power8 tops out at IBM i 7.4.

| Enterprise, flagship | Power 795 (9119-FHB) | E880 (9119-MHE) | E980 (9080-M9S) | E1080 | E1180 (9080-HEU) | Withdrawn Feb 2015; IBM support ended Dec 2020; IBM i 7.3 support ended 2023 | Largest mission-critical consolidation |

What Else Changes Along This Path
- This is the widest generational gap covered anywhere in this portfolio: Power7 predates four full IBM Power generations. A direct Power7-to-Power11 or Power7-to-Power10 jump is usually the more efficient path versus stepping through Power8 or Power9, since those intermediate generations are themselves already past or approaching their own end-of-support windows.
- IBM i 7.6 requires Power10 (minimum firmware FW1060) or Power11 hardware ... it does not run on Power9 or Power8. Neither a Power7-to-Power8 nor a Power7-to-Power9 migration reaches the current IBM i release.
- Every step in this chain moves off Power7's DDR3 memory architecture onto DDR4 (Power8/Power9) or DDR5 (Power10/Power11), changing memory pricing and density substantially.
- Per-core performance has grown dramatically across four generations. See our sizing guide before assuming you need an equivalent or larger core count on the replacement.
- IBM Power Virtual Server offers a non-hardware path off Power7 entirely, running the workload on IBM Cloud-hosted Power infrastructure instead of new owned hardware.
