Power 12
The unofficial, widely used placeholder name for IBM's Power processor and server generation expected after Power11. 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 Power11, based on the established Power generation numbering pattern (Power8, Power9, Power10, Power11). Early evidence of its existence includes GCC compiler patches targeting a post-Power11 "future" processor family, first reported around mid-2025, and public commentary from IBM's own chief architects about the generation's likely direction.
