A developer conducted a horizontal comparison of four acceleration configurations for the MiniMax H3 video model on an RTX 3090. The test environment involved generating a 0.4 MP resolution, 15-second video.
Generation Time Comparison:
- No acceleration: 18m 25s (Baseline)
- SageAttention: 11m 06s (1.66x speedup)
- Spectrum: 11m 17s (1.63x speedup)
- SageAttention + Spectrum: 7m 33s (2.44x speedup, 59% time reduction)
The author also released a comparison video for the community to evaluate visual quality and detail degradation across different configurations.
