Can RTX 6000 Ada 48GB run Llama-3.2-3B-Instruct?

NVIDIA · 48 GB GDDR6 · 960 GB/s bandwidth · Meta · 3.2B · model ctx up to 128K

Yes — the RTX 6000 Ada 48GB (48 GB GDDR6) can run Llama-3.2-3B-Instruct. At Q4 with the default 8K context it needs ≈ 3.4 GB VRAM (weights 1.76 GB + KV cache 0.64 GB + 1 GB runtime overhead), which fits within 48 GB. Decode at Q4/8K: ≈ 190.9 tok/s (estimated, batch 1). FP16 (≈ 8.04 GB) also fits, at ≈ 52.5 tok/s (estimated). 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	3.08 GB	Yes	190.9 est.
Q4	8K default	3.4 GB	Yes	190.9 est.
Q4	32K	5.32 GB	Yes	190.9 est.
FP16	4K	7.72 GB	Yes	52.5 est.
FP16	8K default	8.04 GB	Yes	52.5 est.
FP16	32K	9.96 GB	Yes	52.5 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).
