Running MiniMax H3 on 6GB VRAM: fused turbo beats VDN by ~30% in ComfyUI tests
cgpixel23 · reddit · 2026-09-08
A ComfyUI tutorial compares the new MiniMax H3 fused turbo and VDN models with a workflow optimized for low-VRAM GPUs, tested on an RTX 3060 with only 6GB VRAM and 16GB RAM, including fast-motion and fighting scenes plus a second-sampling upscaling pipeline. Results: fused turbo takes 7 min for 0.4MP generation and 20 min for 1.2MP upscaling, versus 10 and 30 minutes for VDN. The author calls fused turbo one of the best current options, handling both video generation and editing in a single model. Model, workflow and video links included.
