Can RTX 4070 Ti 12GB run NVIDIA-Nemotron-3-Nano-4B-BF16?
NVIDIA · 12 GB GDDR6X · 554 GB/s bandwidth ·
NVIDIA · 4.0B · model ctx up to 256K
Yes — the RTX 4070 Ti 12GB (12 GB GDDR6X) can run NVIDIA-Nemotron-3-Nano-4B-BF16. At Q4 with the default 8K context it needs ≈ 4.0 GB VRAM (weights 2.2 GB + KV cache 0.8 GB + 1 GB runtime overhead), which fits within 12 GB. Decode at Q4/8K: ≈ 88.1 tok/s (estimated, batch 1). FP16 (≈ 9.8 GB) also fits, at ≈ 24.2 tok/s (estimated). 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).
