Can RTX 4070 Ti Super 16GB run NVIDIA-Nemotron-3-Super-120B-A12B-BF16?
NVIDIA · 16 GB GDDR6X · 672 GB/s bandwidth ·
NVIDIA · 120.0B (active 12.0B) · MoE · model ctx up to 256K
No — NVIDIA-Nemotron-3-Super-120B-A12B-BF16 at Q4 needs ≈ 68.2 GB even at 4K context, beyond the RTX 4070 Ti Super 16GB's 16 GB GDDR6X. It would only run with heavy CPU/disk offload. FP16 needs ≈ 243.4 GB — does not fit on this card. Estimates come from memory-bandwidth math; rows tagged measured override estimates. Relative ranking is more reliable than absolute tok/s.

Fits = weights + KV(ctx) + 1 GB overhead ≤ 95% of VRAM. Measured
anchors are context-agnostic; the fit verdict is recomputed per context. A missing tok/s
means the model is far beyond this card (offload-only territory).
