Local Benchmarking of MiniMax H3
The MiniMax H3 video generation model has recently garnered significant attention in the community, with developers conducting local deployment benchmarks ranging from consumer-grade cards to multi-card clusters. Tests indicate the model achieves significantly higher generation efficiency than traditional L40 GPUs via specific workflows like Turbo LoRA, and demonstrates good hardware compatibility.
Confirmed
- Generation Efficiency vs Hardware: It runs and produces credible results on an RTX 3060 12GB; generating an 8-second video at 0.7MP on an RTX 5060 Ti takes an average of 400 seconds; Text-to-Image (1MP) on an RTX 5070Ti takes about 18 minutes; a cluster of 12 RTX 3090s ran continuously for 48 hours.
- Optimal Parameters: Real-world tests show that a 7-second duration with 8-step Light Turbo mode is the best balance for Image-to-Video, taking about 7 minutes under version 0.4; The Turbo LoRA workflow generates medieval scenes in 1.8mp resolution in just 5-8 seconds, compared to 5-10 minutes for regular workflows.
- Feature Support: The model supports Image-to-Video (R2V), multi-lens video generation, and Text-to-Image/Video (T2VA), requiring only slight color grading in post-production.
Unconfirmed
- Specific details on quality differences between different step counts (12 vs 20 steps) and Base vs LoRA modes, despite comparisons existing, no clear quantitative conclusions were drawn.
Why it matters
- MiniMax H3 demonstrates the potential of running high-quality video generation on consumer-grade hardware, lowering the barrier to entry for advanced video generation technology, while providing individual creators with viable localized production solutions through parameter optimization.
