IBM Power 12 Roadmap Outlook
The next IBM Power generation is in development, but its product details remain unpublished. This evidence ledger separates confirmed direction from projections and unsupported specifications.
IBM is working beyond Power 11, but Power 12 is not an announced product name and no model list or specification sheet exists. The useful roadmap is therefore an evidence ladder: what IBM has said directly, what public development work supports, what timing history suggests, and what remains unsupported.
The strongest current conclusion is direction, not configuration. IBM has publicly supported continued AI acceleration and a chiplet approach beyond Power 11. It has not published Power 12 cores, clocks, CPW, rPerf, memory limits, prices, models, manuals, or a release date.
The evidence ranked by confidence
Public Power 12 roadmap evidence
| Roadmap question | Current evidence | Confidence |
|---|---|---|
| Is IBM developing another Power generation? | Post-Power 11 compiler work and IBM engineering commentary point beyond the current generation | High for continued development; no announced product detail |
| Will AI acceleration continue? | IBM Power Processor Chief Architect Bill Starke said Spyre will be part of Power 11 and beyond | High for direction; no next-generation performance claim |
| Will IBM use chiplets? | Starke has described a chiplet direction and the connectivity reason for a hub-and-spoke design | High for direction; low for counts, layout, or product form |
| When could it arrive? | Generation history and related IBM i planning support a window centered on 2028, with 2029 still plausible | Medium; projection only |
| Will it use Samsung 3nm or a 2.5D interposer? | Independent technical analysis has discussed those possibilities | Low; unsupported by an IBM product announcement |
| What are its specifications and prices? | IBM has published none | High confidence that no public specification should be quoted |
Why current Power 11 moves still matter
Power 11 shows what IBM is carrying forward today: the Power instruction set, enterprise scale-up design, Matrix Math Acceleration, Spyre support, DDR5 memory, and expansion into smaller deployment footprints such as the Power S1112. Those choices help define the direction of the platform. They do not turn current features into future specifications.
The S1112 announcement is especially useful as a decision signal because it gives Power 9-era buyers another shipping Power 11 option while the next generation remains unannounced. A current product can be quoted, supported, and compared. A roadmap projection cannot.
Keep each Power 12 question with its evidence
- For launch timing, use the IBM Power 12 release-date evidence.
- For processor architecture, use the Power 12 CPU evidence page.
- For Power 11 against the unannounced generation, use the Power 11 versus Power 12 comparison.
- For a decision based on your own support and workload state, use Power 12 transition planning.
- For the source-by-source filter, use the Power 12 evidence ledger.
Evidence that would change the roadmap
What buyers can act on today
Power 12 remains a monitored roadmap subject, not a purchasable configuration. If support, capacity, or business timing requires a system now, compare the shipping Power 11 generation and use the IBM Power reseller directory to find providers.
