MiniMax H3 Local Tests: Benchmark Results and Comparisons Across GPUs

MiniMax H3 video generation model has been locally tested by the developer community, showing broad compatibility and strong performance on consumer GPUs. With optimizations like EasyCache and SageAttention, generation speeds improve significantly, lowering the barrier for AI video creation.

Confirmed

Runs on multiple GPUs: From RTX 3060 12GB to RTX 5090, all run successfully. @inuptia ran it on an 8GB RTX 4060 Ti at 0.5MP, taking 10 minutes. @JLFilms considers H3 the strongest open-weight solution tried so far.
Speed and hardware load: Generation time varies by resolution and GPU. RTX 5090 takes 15-16 minutes for 11-15s videos (@BlackBeardAI, @Careless-Constant-33), RTX 5070 Ti 18 minutes (@BudgetStop9989), RTX 3060 4-17 minutes (@RobertBrown7425, @merica42069). Full load on RTX 5090 reaches 80-83°C (@Careless-Constant-33). Full bf16 without optimization on RTX PRO 6000 uses 95GB VRAM and takes 2 hours for 1080p (@Moarkush). Optimizations speed up significantly: @Radyschen used pruned int8 with SageAttention on RTX 4080 Super to generate 5s video in 3 minutes; @DeliciousGorilla fixed ComfyUI workflow to generate 10s video on RTX 3090 in 7m39s; @giantcandy2001 on RTX 4060 Ti took 3 minutes.
Quality and performance: @anyup88 notes it surpasses ByteDance Seedance 2.0 in specific scenes. @Ciko15 got impressive results with a single prompt. @AzuliarTHP finds it can produce cinematic shots. Compared to LTX 2.3, @Chemical-Bicycle3240 says H3 wins in character liveliness but lags in long videos. @ResidentSympathy60 discovered hidden multimodal capabilities like image editing and voice cloning.

Unconfirmed

Artifacts: Multiple users report slow-motion output and blurriness at low resolutions (@InterestingRoom2820, @AzuliarTHP), possibly inherent or workflow-related.

Why it matters

Lower barrier: Even on entry-level GPUs, with optimizations, developers can experiment with high-quality video generation.
Multimodal potential: With minimal reference images and audio, multimedia-driven generation is possible (@dilinjabass), showing great potential for complex video creation.
