AMD's next-generation RDNA 4m graphics architecture has been detailed through new software identifiers, with GFX1171 and GFX1172 targets appearing in LLVM compiler code. These GPUs aren't true RDNA 4 parts but rather rebranded RDNA 3.5 extensions designed to support FSR 4 upscaling technology. The targets will power AMD's upcoming Ryzen 500 "Medusa Point" APUs launching in 2026.

Initially thought to be separate architectures, RDNA 3.5 has evolved into RDNA 4m as AMD extends the life of its integrated graphics IP. This rebranding makes strategic sense since AMD plans to use RDNA 3.5-based graphics through 2029 across its laptop and desktop APU lineup. The new targets include support for INT8 and FP8 data formats, enabling FSR 4 functionality on integrated graphics that would otherwise lack modern upscaling capabilities.

The rebranding strategy ensures that consumers buying laptops in the coming years won't experience a significant graphics downgrade. While "Medusa Point" APUs will feature these rebranded RDNA 4m parts, AMD's "Medusa Halo" products will utilize the company's next-generation RDNA 5 architecture. This approach allows AMD to maintain feature parity across its product stack while reserving true RDNA 4 for discrete desktop GPUs.
