Yes — the Titan Xp 12GB (12 GB GDDR5X) can run gemma-4-12b-it. At Q4 with the default 8K context it needs ≈ 9.96 GB VRAM (weights 6.57 GB + KV cache 2.39 GB + 1 GB runtime overhead), which fits within 12 GB. Decode at Q4/8K: ≈ 29.2 tok/s (estimated, batch 1). FP16 needs ≈ 27.29 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	8.77 GB	Yes	29.2 ± est.
Q4	8K default	9.96 GB	Yes	29.2 ± est.
Q4	32K	17.13 GB	No	40.7 ± est.
FP16	4K	26.09 GB	No	4.8 ± est.
FP16	8K default	27.29 GB	No	4.4 ± est.
FP16	32K	34.46 GB	No	2.8 ± 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).
