Running MiniMax-H3 on AMD Strix Halo: 5s clip in 9.5 min, but times vary
danielcar · reddit · 2026-08-14
Developer danielcar ran MiniMax-H3 (video+audio) locally on AMD Strix Halo with 128GB unified memory and no discrete GPU, using ROCm 7.14, ComfyUI, int8 pruned transformer, and 4-step turbo LoRA. A 5-second 896×512 clip took 9.5 minutes, but subsequent generations took 10 minutes and 1 hour respectively. The author notes weights are community pruned conversions, so quality isn't representative of official H3; this was a speed/setup test. Scripts and full writeup shared.
