RDNA

Phoronix's end-of-2025 benchmarking on Linux 6.19 exposed severe hard hangs on AMD's newer RDNA3 and RDNA4 GPUs, halting tests across kernels 6.18 and 6.19—with no fixes from AMD or kernel logs for diagnosis. Building on prior coverage of performance boosts for legacy GCN GPUs now defaulting to AMDGPU, tests succeeded steadily on a wide range of older and mid-range hardware using Mesa 26.0-devel drivers.
