RDNA 4m GPU driver support appears, but AMD is expected to use RDNA 3.5 integrated graphics until 2029

Q: Which upcoming AMD processor is expected to include RDNA 4m integrated graphics and what CPU architecture will it pair with?

RDNA 4m is expected to be included in AMD's upcoming 10-core "Medusa Point" processor, and it will pair with AMD's next-generation Zen 6 CPU architecture.

Q: Which RDNA 4m GPU identifiers have appeared in Mesa, and what does their presence in Mesa 26.3 indicate about driver support?

The RDNA 4m GPU identifier GFX1171 has been merged into Mesa 26.3, and GFX1172 is a second known RDNA 4m configuration expected to be added to Mesa in the future. Their presence in Mesa 26.3 indicates that open-source Linux driver support for at least GFX1171 is already being integrated into the Mesa graphics stack ahead of the rumored Q4 2026 launch.

Q: How does AMD's plan to keep RDNA 3.5 in APUs until 2029 affect the availability of FSR 4 on integrated Radeon RX graphics?

Keeping RDNA 3.5 in APUs until 2029 means integrated Radeon RX graphics will not get native FSR 4 support until AMD ships RDNA 4m in a future APU, since RDNA 4m is the architecture said to bring native FSR 4. The article notes there is still a chance AMD could port a version of FSR 4 to RDNA 3.5, but that is not confirmed.

Q: Are there multiple RDNA 4m configurations mentioned in the article, and how are they labeled (e.g., GFX1171, GFX1172)?

Yes. The article mentions two RDNA 4m configurations labeled GFX1171 and GFX1172, with GFX1171 already merged into Mesa 26.3 and GFX1172 noted as one of the two known RDNA 4m configurations expected to be added to Mesa in the future.

RDNA 4m is expected to be a part of AMD's upcoming 10-core 'Medusa Point' processor with Zen 6 CPU cores, and will deliver native FSR 4 support.

TL;DR: AMD will keep RDNA 3.5 for integrated graphics in APUs until 2029, while a mobile RDNA 4m GPU (GFX1171, with GFX1172 variant) is expected in the 10-core "Medusa Point" Zen 6 processor, adding native FSR 4 support and INT8 capability; RDNA 4m have been merged into Mesa 26.3 ahead of a rumored Q4 2026 launch.

Based on reports, AMD is planning to keep using its RDNA 3.5 architecture for its integrated graphics as part of its APU line-up until 2029. RDNA 3.5 powers the integrated Radeon RX graphics in its Ryzen AI 300 and 400 Series processors, while also powering gaming handhelds like the ROG Xbox Ally X from ASUS and Legion Go 2 from Lenovo.

That said, RDNA 4m is expected to be included in the company's upcoming 10-core 'Medusa Point' processor that will also leverage its next-generation Zen 6 CPU architecture. According to leaks and early information on RDNA 4m, the new mobile GPU architecture is something of an in-between, as in not the full RDNA 4 we see on the current Radeon RX 9000 Series desktop lineup.

These leaks note that it supports INT8 data types, so it will bring native FSR 4 technology support to the table, which is a big win for mobile AMD graphics and portable PC gaming. As spotted by Phoronix, RDNA 4m, under the name GFX1171 GPU, has been merged into Mesa 26.3, the Linux-based open-source graphics driver stack, ahead of its rumored Q4 2026 launch.

According to Phoronix, the GFX1172 GPU is one of two known RDNA 4m configurations, with GFX1172 also expected to be added to Mesa in the future. Of course, bringing the vastly improved AI-powered FSR 4 Upscaling to its integrated graphics lineup is something that needs to happen; with older desktop RDNA generations finally getting support, there's still a chance that we could see a version of FSR 4 arrive for RDNA 3.5.

In addition to RDNA 4m, the flagship next-gen 'Medusa Halo' processor will reportedly leverage the company's upcoming RDNA 5 or UDNA architecture, which will presumably offer far more powerful AI and graphics capabilities, including support for real-time ray-tracing on a mini PC or handheld.
