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.
Of every signal tracked on this site, this is the one closest to an actual IBM commitment rather than outside inference: IBM Power Processor Chief Architect Bill Starke told IT Jungle directly that the Spyre Accelerator "will be a piece of the Power11 portfolio and beyond," alongside continued evolution of IBM's WatsonX model lineup.
Combined with Power11's existing on-chip Matrix Math Acceleration and the broader IBM pattern visible in Telum II (z17) and the AIU research chip family, the throughline is consistent: IBM is treating AI inference acceleration as a permanent, cross-generational feature of its enterprise silicon, not a one-generation experiment. What remains unconfirmed is the specific form that takes in a next-generation Power chip -- whether that means an expanded on-chip accelerator, a next-generation Spyre card, or something not yet disclosed.

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.
Frequently Asked
Will Power 12 have on-chip AI acceleration?
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 Power11 portfolio and beyond," alongside continued evolution of IBM's WatsonX models. The specific form that takes for the next generation -- expanded on-chip acceleration, a next-generation Spyre card, or otherwise -- has not been disclosed.
