Running MiniMax H3 on RTX 5090: 12 Mins for an 8-Sec 1080P Video
jefharris · reddit · 2026-08-06
A developer shared benchmark results using the MiniMax H3 Image-to-Video (I2V) workflow. Rendering an 8-second video at 1920x1088 resolution takes approximately 12 minutes on an RTX 5090 GPU.
The author also noted a tip on resolution settings: rendering directly at the 2K setting yields significantly better prompt adherence compared to the 1K setting. The workflow was built using the official ComfyUI tutorial.
