On an RTX 4070 Ti (12 GB), Nemotron 3 Nano 4B in Q4_K_M needs about 4,2 Go of video memory: it should fit. Estimated generation speed: ≈ 156 tokens/s.

Calculation: Gemma 3n E2B measured at 163 tok/s on this card, 2,6 Go read per token → × 2,6 Go ÷ 2,7 Go ≈ 156 tok/s (generation is memory-bound: speed follows the amount of weights read).

Estimated VRAM = file + KV cache (full-attention layers, f16) + ~0,5 Go of buffers, excluding memory used by the system — hence the slightly higher “recommended VRAM”, which keeps that margin. Speed ≈ estimated speed × weights read ÷ (weights read + added KV cache).
Estimates based on real measurements of other models on this card and on the model's public data (NVIDIA Nemotron). As soon as a measurement exists, this page shows the real figures.
