RTX 3090 Test: INT8 Quantization Doubles MiniMax Video Generation Speed
Nevaditew · reddit · 2026-08-06
A developer benchmarked the MiniMax H3 video generation model under different quantization modes on an RTX 3090. Tests show that using the INT8 ConvRot (W8A8) node reduces generation time from 270s to 200s compared to FP8 scaled mode, with virtually no difference in visual quality.
