Can RTX A6000 48GB run gemma-3-27b-it?

NVIDIA · 48 GB GDDR6 · 768 GB/s bandwidth · Google · 27.4B · model ctx up to 128K

Yes — the RTX A6000 48GB (48 GB GDDR6) can run gemma-3-27b-it. At Q4 with the default 8K context it needs ≈ 21.51 GB VRAM (weights 15.07 GB + KV cache 5.44 GB + 1 GB runtime overhead), which fits within 48 GB. Decode at Q4/8K: ≈ 18.0 tok/s (estimated, batch 1). FP16 needs ≈ 61.24 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	18.79 GB	Yes	18.0 est.
Q4	8K default	21.51 GB	Yes	18.0 est.
Q4	32K	37.83 GB	Yes	18.0 est.
FP16	4K	58.52 GB	No	9.5 est.
FP16	8K default	61.24 GB	No	8.7 est.
FP16	32K	77.56 GB	No	5.4 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).
