IBM Power 12 FAQ

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.

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.

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.

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.

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.

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.

No. iSeries was an older IBM server brand in the AS/400 family history. IBM i is the operating system. IBM Power is the modern server family that can run IBM i, AIX, and Linux. People still use AS/400 or iSeries casually when they mean an IBM i environment, but the current hardware line is IBM Power.

There is no Power 12 cost yet. IBM has not announced Power 12 models, software tiers, processor feature codes, or price guidance. Any Power 12 price published before an IBM announcement is invented. Budget planning should use real Power 11 quotes, support timelines, and refresh windows until IBM publishes actual Power 12 data.

If you have a support, capacity, security, or modernization problem now, Power 11 is the only current-generation buying option. If your environment is stable and your refresh timing naturally lands near 2027 or 2028, it is reasonable to keep Power 12 on the planning radar. Do not delay a needed Power 9 or Power 10 refresh around unannounced Power 12 specs.

IBM Power Processor Chief Architect Bill Starke has confirmed the generation after Power 11 is expected to move to a chiplet architecture, with a hub-and-spoke I/O topology instead of AMD's centralized-I/O approach. No specific chiplet count, core layout, socket count, or product detail has been disclosed.

This is the most directly confirmed forward-looking AI signal available: IBM Power Processor Chief Architect Bill Starke has stated the Spyre AI Accelerator "will be a piece of the Power 11 portfolio and beyond," alongside continued evolution of IBM's WatsonX models. The specific form that takes for the next generation has not been disclosed.

Not confirmed. IBM has stated it evaluates process jumps by delivered customer benefit rather than chasing the industry's most advanced nodes. Some independent analysis speculates a mature 5nm or 3nm Samsung process, possibly with 2.5D interposer packaging, but this specific detail is unconfirmed.

There is no Power 12-specific IBM statement on this, but IBM's consistent, decades-long philosophy has preserved software compatibility for IBM i and AIX workloads across prior Power generations, including the Power 10-to-Power 11 transition. No sourced signal suggests that pattern breaks for Power 12.

Telum II is a mainframe processor powering IBM's z17 system, not a Power chip, and IBM has not stated Power 12 uses Telum II silicon. It matters here because it is the clearest public evidence of IBM's on-chip AI inference strategy, which has already extended into the Power line through the Spyre Accelerator's confirmed Power 11 compatibility.

Bill Starke is IBM's Power Processor Chief Architect and the most consistent public voice on Power's silicon direction. Kris Whitney became IBM i Chief Architect in 2026, succeeding Steve Will after a 41-year IBM career. Jeff Scheel leads Linux for Power architecture, and Yan Zhuo leads IBM i product management.

Because IBM has not published any. Publishing invented core counts, clock speeds, model numbers, or prices would misrepresent speculation as fact. This site tracks sourced statements, patterns, and analyst projections, each with an explicit confidence label, until IBM makes a real announcement.

This site's sibling, power11.as400system.com, is the specification authority for the current, shipping Power 11 generation, including the S1112, S1122, S1124, L1122, L1124, E1150, and E1180 models, plus pricing notes where real example configurations are available.

Any change IBM makes to the Power instruction set architecture, including a chiplet transition, happens within the governance and royalty-free licensing structure the OpenPOWER Foundation maintains. The Foundation itself does not set IBM's product roadmap, but it is the institutional backdrop for IBM's stated commitment to ISA continuity and controlled openness across generations.
