IBM Power 12 Roadmap Intelligence
What Comes After
IBM Power 11
IBM has not announced Power 12. This site tracks the questions buyers are already asking ... release date, specs, manuals, Power 11 cost context, operating system support, AI technology, engineering leadership, and sourced roadmap signals ... while labeling everything unconfirmed as speculation.
Confirmed AI Technology Foundations
Real, shipping IBM AI silicon and interconnect technology that Power 12 is expected to build on -- not invented specs.
IBM Telum II Processor
IBM's mainframe-class processor with a native, on-chip AI accelerator delivering 24 trillion operations per second -- four times the AI throughput of the original Telum chip.
PCIe AI Accelerator CardIBM Spyre Accelerator
IBM's PCIe-based AI accelerator card, built for on-premises generative and traditional AI inference, with confirmed Power11 compatibility arriving December 2025.
AI Research SiliconIBM AIU Chip Family
IBM Research's family of purpose-built AI accelerator chips, the research lineage feeding IBM's production AI silicon strategy across mainframe, Power, and cloud.
Proprietary Memory InterconnectOpen Memory Interface (OMI)
IBM's proprietary memory interconnect, replacing direct DDR signaling with a high-speed serial protocol that already powers Power10 and Power11's DDR5 DDIMM memory.
Open Hardware Standards BodyOpenPOWER Foundation
The IBM-founded, now community-governed foundation that opened the Power ISA to royalty-free licensing, and the institutional structure that any Power12 architecture change has to work within.
Power 12 Roadmap Signals
Every sourced signal about IBM's next Power generation, rated by confidence -- never presented as confirmed specification.
Chiplet Hub-and-Spoke Architecture
IBM's post-Power11 generation is expected to move to a chiplet design -- but with a hub-and-spoke I/O layout instead of the centralized-I/O approach used by AMD.
Samsung Process Node & 2.5D Interposer Speculation
IBM is expected to use a mature Samsung process (5nm or 3nm class) for its post-Power11 chips rather than chasing the industry's bleeding-edge nodes -- a deliberate, stated strategy, not a limitation.
Three-Year Power Release Cadence
Power10 (2021) to Power11 (2025) is a four-year gap, but IBM's broader pattern -- and independent analysis -- points to a roughly three-year cadence going forward, putting a plausible Power12 window around 2027-2028.
IBM i 8.1 Lifecycle Alignment
IBM i 7.6 shipped April 2025; the next major release, IBM i 8.1 (internally referenced as IBM i Next), is projected for 2028 -- the same window analysts expect for Power12, and IBM has historically aligned major IBM i releases with new Power hardware generations.
AI Inference Continuity Signal
IBM has stated on the record that its Spyre-based AI acceleration strategy extends beyond Power11 -- the strongest single data point that Power12 inherits, and likely expands, on-chip and on-node AI inference.
Power S1112 Edge and AI Signal
IBM's July 2026 Power S1112 announcement does not reveal Power 12, but it shows IBM expanding Power 11 into smaller, AI-ready, branch and edge deployments while the next generation remains private.

IBM Power 12 Questions Buyers Are Already Asking
Early Power 12 searches are not abstract. Buyers want a release date, specs, a manual, Power 11 cost context, supported operating systems, and plain-English iSeries naming help.
Chiplets Are Coming to Power: The Hub-and-Spoke Bet Explained
IBM's own chief architect has confirmed the generation after Power 11 moves to chiplets ... and described a design that deliberately does not copy AMD's approach.
From Telum II to Power 12: How IBM's AI Silicon Strategy Connects
Telum II, the AIU research chips, and the Spyre Accelerator are not separate stories ... they're one AI silicon strategy expressed across three IBM product lines.
Common Questions
Has IBM announced Power 12?
No. "Power 12" is an unofficial, industry-standard placeholder name for the Power generation expected after Power 11. IBM has not confirmed the name, a release date, or any specifications. Early evidence of its existence includes GCC compiler patches targeting a post-Power 11 processor family, first reported around mid-2025.
When will IBM Power 12 be released?
No date has been announced. Extrapolating IBM's roughly three-year Power and IBM i release cadence from Power 11's 2025 launch, then cross-checking the independently projected 2028 window for IBM i 8.1, gives a plausible 2027 to 2028 watch window. That is an analyst projection, not an IBM commitment.
Where can I find IBM Power 12 specs or a manual?
You cannot, because IBM has not published a Power 12 manual, Redbook, sales manual entry, model list, core count, CPW figure, rPerf figure, or price. Power 11 documentation exists for current hardware. Power 12 documentation does not exist yet, so any page claiming fixed Power 12 specs today is guessing.
What are the key differences between IBM Power 9 and Power 11?
Power 11 is two generations newer than Power 9. The practical differences are current IBM support, newer firmware and HMC requirements, DDR5 DDIMM memory over Open Memory Interface, on-chip Matrix Math Acceleration for AI inference, current IBM i/AIX/Linux support levels, and better entry-system efficiency. IBM's July 2026 Power S1112 announcement gives one useful entry-class anchor: IBM says the S1112 delivers 2x better core performance and up to 69% better energy efficiency versus the Power S914. For a Power 9 shop, Power 11 is the real quoting target today. Power 12 is still future planning.
What OS can run on IBM Power?
IBM Power systems can run IBM i, AIX, and Linux, usually separated into logical partitions through PowerVM, with VIOS handling shared I/O in many designs. The exact supported versions depend on the server generation and firmware level. Power 11 has published support guidance for current IBM i, AIX, and Linux levels. Power 12 has no published operating system matrix because IBM has not announced the hardware.
How much does IBM Power 11 cost?
IBM does not publish a simple fixed price list for Power 11 servers. The quote depends on the model, processor feature code, memory, internal storage, adapters, HMC or vHMC requirements, IBM i/AIX/Linux software tier, support, and services. Use Power 11 pricing as the practical budget anchor for now, because Power 12 has no price and no announced model list.
Glossary
- AIU (Artificial Intelligence Unit) — IBM Research's family of experimental AI accelerator chips, the upstream research lineage feeding IBM's production AI silicon designs.
- AIX — IBM's UNIX operating system for IBM Power servers, commonly run in its own logical partitions beside IBM i or Linux.
- Chiplet Architecture — A processor design approach that splits what was once a single monolithic chip into multiple smaller, interconnected silicon dies (chiplets), often on different manufacturing processes.
- CPW (Commercial Processing Workload) — IBM's proprietary relative performance benchmark for IBM i commercial workloads, used to compare capacity across Power model tiers and generations.
- Hub-and-Spoke I/O — IBM's expected chiplet I/O topology for the post-Power 11 generation: a single central I/O hub chiplet surrounded by compute chiplets, rather than centralizing I/O separately from compute.
- IBM i — IBM's integrated operating system for IBM Power servers, descended from OS/400 and commonly still called AS/400 by long-time users.
- IBM i 8.1 (IBM i Next) — The projected next major IBM i operating system release after 7.6, independently projected for 2028 ... the same window analysts expect for Power 12.
- IBM Power — IBM's current enterprise server family for IBM i, AIX, Linux, and hybrid workloads, built around the Power processor architecture.
