AMD's Linux kernel patches suggest enablement of next-gen Instinct MI400-series AI GPU accelerators

AMD is uploading Linux kernel patches for potential next-gen Instinct MI400-series AI GPU accelerators, hinting at support for CDNA5 architecture. The GFXHUB 12.1 inclusion suggests this may be for the MI430 and MI450-series accelerators. The IP blocks being enabled include PSP 15.0.8, IH 7.1, MMHUB 4.2, GFXHUB 12.1, and GMC 12.1. This move aligns with AMD's roadmap for AI and HPC segments, possibly indicating a forthcoming refresh of Instinct accelerators. The article also discusses potential monikers for different GPU series and speculates on AMD's competitive positioning against Nvidia.
