OPTCRulez · reddit · 2026-08-06
A user running MiniMax H3 image-to-video tasks on an AMD 9070XT GPU and 5800X3D CPU using ComfyUI default settings (0.4MP, 5s duration) reported a massive render time of 154 minutes, compared to just a few minutes on high-end NVIDIA cards like the RTX 5090.
The author sought optimization solutions for AMD hardware. Community suggestions include using the --fast-disk flag when launching ComfyUI, and trying to integrate SageAttention and KJ Nodes to improve processing efficiency.
