AMD Begins Driver Support For RDNA 3.5 "GFX1151" GPUs For High-End Strix Halo APUs 1

AMD has started rolling out driver support for its RDNA 3.5 "GFX1151" GPU which will be featured in the premium Strix Halo APUs for notebooks.

AMD's next-gen Strix APUs will come in two variants, a monolithic and a chiplet offering. Both chips are expected to feature the refined RDNA 3.5 integrated GPUs with the mono chip going with a GFX 1150 (16 CU) design and the chiplet variant going with a GFX1151 (40 CU) design. We have seen the company begin support for the mono (GFX 1150) variant a while back and now, the red team starts its enablement journey for the higher-end chip.

In the MESA 24.1 update for the RadeonSI/RADV drivers, AMD engineers have added the relevant code to enable the GFX1151 IP which means that the preliminary work has begun on the high-end Strix APUs.

There's not a whole lot of information within the code itself but AMD Strix APUs are expected to be a major leap over the Hawk Point APUs which were mostly a refresh of the Phoenix chips based on the Zen 4 CPU and RDNA 3 GPU architectures. Meanwhile, Strix will incorporate newer Zen 5 cores & the latest RDNA 3.5 GPU cores which are expected to deliver better performance and better APU efficiency.
