Local MiniMax H3 video gen on RTX 5060 8GB: 27 tests charted, gen time scales steeply with resolution
rguerraf · reddit · 2026-11-01
The author ran 27 local video generation tests with MiniMax H3 on a consumer GPU. Charted data (RTX 5060 8GB, 4 steps, c-kitchen, 32GB RAM) shows generation time climbing steeply with resolution: 70s to 270s for 2.5s videos from 0.2MP to 2.0MP, up to 360s for 5s clips, and 10s videos already costing 250s at just 0.6MP.
GPU stayed at 100% utilization without VRAM-overflow slowdowns, prompting the author to wonder if ComfyUI's memory management has ended the "RAM-pocalypse." They ask whether 16GB RTX 5060 cards differ and whether more RAM could unlock 10s at 1MP.
