AMD is quietly expanding its RDNA 4m graphics branch, and new updates in LLVM show that the company is preparing multiple GPU targets under this lineup. A pending pull request adds GFX1171 and GFX1172 alongside the earlier GFX1170, which confirms that AMD is working on more than one configuration within this architecture. All three targets sit under the same RDNA 4m section, which signals a structured rollout rather than a one-off experiment.
Phoronix reports that GFX1171 and GFX1172 currently follow the same code paths and instruction set capabilities as GFX1170, and there are no functional differences documented yet. That suggests AMD is laying the groundwork first, while keeping room for differentiation later as development continues.

GFX1170 first appeared earlier this year as part of the GFX11 family, which is usually tied to RDNA 3 GPUs. However, RDNA 4m introduces new features that move it closer to RDNA 4 behavior, including support for FP8 and BF8 conversions, along with WMMA and SWMMAC updates. These additions point toward stronger machine learning performance and compatibility with newer technologies like FSR4.
Current speculation links RDNA 4m to upcoming Medusa Point APUs, although AMD has not confirmed any product tied to these GPU targets. The presence of multiple GFX117x entries indicates that AMD is testing different variants, likely for future chips that blend efficiency with advanced graphics and AI capabilities.
