Power7 to 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 upgrade path -- every migration off Power7 is a hardware refresh, not an in-place update, and it is the widest generational gap of any migration covered on this portfolio. The table below maps each Power7 tier through its Power8 and Power9 predecessors-in-sequence 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 to land on hardware that supports IBM i 7.6 without a second refresh in a few years, Power10 or Power11 is the more direct path 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, large scale-up | Power 780 (9179-MHB/MHC/MHD) | E870 (9119-MME) | E980 (9080-M9S) | E1080 | E1180 (9080-HEU) | IBM support ended 2019-2020; IBM i 7.3 support ended 2023 | Large multi-node enterprise consolidation |
| Enterprise, flagship | Power 795 (9119-FHB) | E880 (9119-MHE) | E980 (9080-M9S) | E1080 | E1180 (9080-HEU) | Withdrawn Feb 2015; IBM support ended Dec 2020; IBM i 7.3 support ended 2023 | Largest mission-critical consolidation |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.
