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 · 8s at ~1.4 h per clip. 2 high-end combinations are not recommended (pagefile pressure or >90 min per clip) — see the ✕ marks below. For comfortable 768p: add RAM to 64GB, or move to a card with 16GB+.
Recommended combo (Starter tier (8-10GB VRAM))
- Main model: MiniMax-H3-FL2VA-Pruned-Q3_K_M.gguf（8.9GB）
- Text encoder: qwen3vl_32b_minimax_h3_nvfp4_awq.safetensors（15.69GB）
- Acceleration: LightX2V Turbo 8-step v1.0 · ~2.08× sampling
- Launch flags:
--fast-disk--disable-mmap--lowvram
480-540p 5s; 4-8 steps; 3-10 min per clip; start at 736x416
FAQ
Can the RTX 3060 Ti 8GB run MiniMax H3?
Yes. Estimated with 32GB RAM + fast-disk: 1920×1088·8s at ~1.4 h per clip. Configs that exceed VRAM fall back to weight offloading (slower, but they still render).
How fast is H3 on the RTX 3060 Ti 8GB?
About 1.4 h per 1920×1088·8s clip (including model load and encoding). Longer or denser clips scale quadratically in the attention term.
How much RAM do I need?
At least 32GB of system RAM recommended (minimum 16GB plus a 48GB 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 8-step v1.0), enable SageAttention / Kitchen attention; for long clips try SLA / VSA sparse attention. All of it is switchable in step 2 of the calculator.
