Can RTX 3080 10GB run gemma-3-12b-it?

NVIDIA · 10 GB GDDR6X · 760 GB/s bandwidth · Google · 12.2B · model ctx up to 128K

Partly — gemma-3-12b-it at Q4 fits the RTX 3080 10GB (10 GB GDDR6X) at 4K context (≈ 8.91 GB) but not at the default 8K (≈ 10.11 GB needed). Use a shorter context or partial offload. Decode at Q4/8K: ≈ 112.7 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	40.3 est.
Q4	8K default	10.11 GB	No	112.7 est.
Q4	32K	17.31 GB	No	38.4 est.
FP16	4K	26.6 GB	No	4.5 est.
FP16	8K default	27.8 GB	No	4.1 est.
FP16	32K	35.0 GB	No	2.6 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).
