No — Qwen3.6-35B-A3B at Q4 needs ≈ 20.84 GB even at 4K context, beyond the Titan X Pascal 12GB's 12 GB GDDR5X. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 95.7 tok/s (estimated, batch 1). FP16 needs ≈ 73.08 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	20.84 GB	No	96.1 ± est.
Q4	8K default	20.88 GB	No	95.7 ± est.
Q4	32K	21.1 GB	No	93.7 ± est.
FP16	4K	73.04 GB	No	—
FP16	8K default	73.08 GB	No	—
FP16	32K	73.3 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).
