Times are per whole clip (model load and text encoding included); the first run is slower due to kernel compilation. ⚠ = weight offloading / noticeably slower; ✕ = not recommended.

Reading the numbers

With the recommended combo, the green (no disk spill) ceiling is 1920 × 1088 · 10s at ~59 min 25 s per clip. 1 high-end combinations are not recommended (pagefile pressure or >90 min per clip) — see the ✕ marks below. To unlock 2.0MP and full durations: step up to a 32GB card (e.g. 5090), or use a smaller quant (GGUF Q3/Q4).

Recommended combo (Blackwell-specific (50-series 16GB+))

Main model: MiniMax-H3_FL2VA-NVFP4-HQ.safetensors（DmitryDB）（14.6GB）
Text encoder: qwen3vl_32b_minimax_h3_nvfp4_awq.safetensors（15.69GB）
Acceleration: LightX2V Turbo 4-step v1.1 768p · ~3.44× sampling
Launch flags: --fast-disk

768p 5s; 4-8 steps; 1-5 min per clip

NVFP4 requires sm_120; SLA / VSA sparse attention can speed things up further (1.4-1.75x on long clips, see the attention options in step 2)

FAQ

Can the RTX 4060 Ti 16GB run MiniMax H3?

Yes. Estimated with 32GB RAM + fast-disk: 1920×1088·10s at ~59 min 25 s per clip. Configs that exceed VRAM fall back to weight offloading (slower, but they still render).

How fast is H3 on the RTX 4060 Ti 16GB?

About 59 min 25 s per 1920×1088·10s clip (including model load and encoding). Longer or denser clips scale quadratically in the attention term.

How much RAM do I need?

At least 64GB of system RAM recommended (minimum 32GB plus a 16GB pagefile). With 32GB, always enable --fast-disk or weights spill into the pagefile.

How can I make it faster?

Stack step distillation (e.g. LightX2V Turbo 4-step v1.1 768p), enable SageAttention / Kitchen attention; for long clips try SLA / VSA sparse attention. All of it is switchable in step 2 of the calculator.
