Yes — the Titan V 12GB (12 GB HBM2) can run Qwen3.5-9B. At Q4 with the default 8K context it needs ≈ 6.15 GB VRAM (weights 4.92 GB + KV cache 0.22 GB + 1 GB runtime overhead), which fits within 12 GB. Decode at Q4/8K: ≈ 46.4 tok/s (estimated, batch 1). FP16 needs ≈ 19.12 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	6.03 GB	Yes	46.4 ± est.
Q4	8K default	6.15 GB	Yes	46.4 ± est.
Q4	32K	6.82 GB	Yes	46.4 ± est.
FP16	4K	19.01 GB	No	14.5 ± est.
FP16	8K default	19.12 GB	No	14.3 ± est.
FP16	32K	19.79 GB	No	13.4 ± 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).
