Can RTX 6000 Ada 48GB run Qwen2.5-72B-Instruct?

NVIDIA · 48 GB GDDR6 · 960 GB/s bandwidth · Alibaba · 72.7B · model ctx up to 128K

No — Qwen2.5-72B-Instruct at Q4 needs ≈ 48.26 GB even at 4K context, beyond the RTX 6000 Ada 48GB's 48 GB GDDR6. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 17.9 tok/s (estimated, batch 1). FP16 needs ≈ 160.94 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	48.26 GB	No	23.8 est.
Q4	8K default	55.53 GB	No	17.9 est.
Q4	32K	99.15 GB	No	5.6 est.
FP16	4K	153.67 GB	No	0.6 est.
FP16	8K default	160.94 GB	No	0.6 est.
FP16	32K	204.56 GB	No	—

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).
