Power 12
The unofficial, widely used placeholder name for IBM's Power processor and server generation expected after Power 11. IBM has not confirmed this name, a release date, or any specifications.
"Power 12" is not an IBM-announced product name ... it is the industry's placeholder for whatever comes after Power 11, based on the established Power generation numbering pattern (Power 8, Power 9, Power 10, Power 11). Early evidence of its existence includes GCC compiler patches targeting a post-Power 11 "future" processor family, first reported around mid-2025, and public commentary from IBM's own chief architects about the generation's likely direction.
