Yes — the Titan X Pascal 12GB (12 GB GDDR5X) can run Qwen2.5-7B-Instruct. At Q4 with the default 8K context it needs ≈ 6.7 GB VRAM (weights 4.18 GB + KV cache 1.52 GB + 1 GB runtime overhead), which fits within 12 GB. Decode at Q4/8K: ≈ 40.2 tok/s (estimated, batch 1). FP16 needs ≈ 17.72 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.

Fit & speed by quant and context

Quant	Context	VRAM needed	Fits?	tok/s (decode)
Q4	4K	5.94 GB	Yes	40.2 ± est.
Q4	8K default	6.7 GB	Yes	40.2 ± est.
Q4	32K	11.26 GB	Yes	40.2 ± est.
FP16	4K	16.96 GB	No	15.7 ± est.
FP16	8K default	17.72 GB	No	14.4 ± est.
FP16	32K	22.28 GB	No	9.1 ± 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).
