Can RTX 4070 Ti Super 16GB run gemma-3-12b-it?

NVIDIA · 16 GB GDDR6X · 672 GB/s bandwidth · Google · 12.2B · model ctx up to 128K

Yes — the RTX 4070 Ti Super 16GB (16 GB GDDR6X) can run gemma-3-12b-it. At Q4 with the default 8K context it needs ≈ 10.11 GB VRAM (weights 6.71 GB + KV cache 2.4 GB + 1 GB runtime overhead), which fits within 16 GB. Decode at Q4/8K: ≈ 35.6 tok/s (estimated, batch 1). FP16 needs ≈ 27.8 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	8.91 GB	Yes	35.6 est.
Q4	8K default	10.11 GB	Yes	35.6 est.
Q4	32K	17.31 GB	No	87.0 est.
FP16	4K	26.6 GB	No	10.1 est.
FP16	8K default	27.8 GB	No	9.3 est.
FP16	32K	35.0 GB	No	5.9 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).
