Minimax H3 VRAM Paradox: Higher Resolution Actually Uses Less Memory?
gerentedesuruba · reddit · 2026-08-06
A developer running the Minimax H3 model via ComfyUI on an RTX 5060 Ti (16GB) encountered a counterintuitive VRAM management behavior. Tests showed that generating a 0.7MP/6-second video actually consumed less VRAM (9.6GB) compared to a 0.5MP/5-second video (12GB).
The author questions whether ComfyUI is aggressively offloading model weights from VRAM to prevent OOM errors, and asks if leaving hardware resources underutilized means they are missing out on potential generation performance.
