Can RTX A6000 48GB run Nemotron-3-Nano-Omni-30B-A3B-Reasoning-BF16?

NVIDIA · 48 GB GDDR6 · 768 GB/s bandwidth · NVIDIA · 30.0B (active 3.0B) · MoE · model ctx up to 256K

Yes — the RTX A6000 48GB (48 GB GDDR6) can run Nemotron-3-Nano-Omni-30B-A3B-Reasoning-BF16. At Q4 with the default 8K context it needs ≈ 18.1 GB VRAM (weights 16.5 GB + KV cache 0.6 GB + 1 GB runtime overhead), which fits within 48 GB. Decode at Q4/8K: ≈ 162.9 tok/s (estimated, batch 1). FP16 needs ≈ 61.6 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. Methodology.

Fit & speed by quant and context

Quant	Context	VRAM needed	Fits?	tok/s (decode)
Q4	4K	17.8 GB	Yes	162.9 est.
Q4	8K default	18.1 GB	Yes	162.9 est.
Q4	32K	19.9 GB	Yes	162.9 est.
FP16	4K	61.3 GB	No	78.5 est.
FP16	8K default	61.6 GB	No	77.7 est.
FP16	32K	63.4 GB	No	73.4 est.

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).
