New LLVM patches confirm additional RDNA 4m variants alongside GFX1170 with similar instruction capabilities.
AMD Quietly Expands Next-Gen iGPU Roadmap by Adding New RDNA 4m Graphics Targets, GFX1171 and GFX1172
Earlier compiler patches showed that RDNA 4m incorporates several RDNA 4-style instruction-set upgrades, such as support for FP8 and BF8 data formats, along with WMMA matrix instructions used in AI workloads. Now, AMD is further expanding its next-gen integrated GPU roadmap, as new Linux compiler patches unveil two additional RDNA 4m graphics targets. These are the GFX1171 and GFX1172.
These targets are now joining the recently discovered GFX1170, confirming that AMD is preparing multiple variants under the same architecture. As spotted by Phoronix, the new graphics targets appeared in the LLVM changes in AMD's open-source graphics stack. Both GFX1171 and GFX1172 appeared under the RDNA 4m label and share identical instruction-set capabilities.
The RDNA 4m labelling is interesting in itself, since it isn't associated with RDNA 4 at all. RDNA 4 has been strictly reserved for the discrete GPU lineup and won't be seen on the upcoming AMD SoCs. The RDNA 4m falls under the GFX11 family, which is associated with the RDNA 3 architecture. Linux documentation also identified the original GFX1170 target as an APU or SoC-class GPU rather than a discrete Radeon GPU.
Hence, the current expectations indicate that the GFX1170 family will be utilized in the Zen 6-based Medusa Point APUs. So, think of the RDNA 4m as a bridge between the RDNA 3.5 and RDNA 4 architecture. Keep in mind that Medusa Point will succeed the Zen 5-based Strix Point chips, which boast RDNA 3.5-based iGPUs, and a significant GPU-architectural change is only expected with the Medusa Halo chips. Medusa Halo is expected to feature AMD RDNA 5 graphics, bringing a true generational change to the mobile platform, and is also going to support next-gen LPDDR6 memory.
