AMD has published HIPRT 3.2, its latest ray tracing library for HIP, and the release notes explicitly name the integrated graphics of upcoming Zen 6 Medusa processors. Under new features, AMD lists three GPU architecture IDs: gfx1170, gfx1171, and gfx115E.
The gfx117x IDs belong to RDNA 4m, which first appeared in LLVM in February. AMD added GFX1171 and GFX1172 targets in March, merged GFX1171 into Mesa 26.3 in August, and pushed RDNA 4m firmware later that month. Despite the name, RDNA 4m sits in the GFX11 family alongside RDNA 3 and 3.5, with additions like FP8/BF8 conversion and new matrix instructions.
The gfx115E entry is more curious. GFX115x covers RDNA 3.5 graphics in Strix Point and Strix Halo, suggesting at least one Medusa chip may retain RDNA 3.5. AMD hasn't specified which Medusa parts get which GPU, and HIPRT 3.2 remains a pre-release on GitHub.
