Can RTX 3060 12GB run Qwen3-Coder-30B-A3B-Instruct?

NVIDIA · 12 GB GDDR6 · 360 GB/s bandwidth · Alibaba · 30.5B (active 3B) · MoE · model ctx up to 128K

No — Qwen3-Coder-30B-A3B-Instruct at Q4 needs ≈ 18.08 GB even at 4K context, beyond the RTX 3060 12GB's 12 GB GDDR6. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 93.0 tok/s (estimated, batch 1). FP16 needs ≈ 62.6 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	18.08 GB	No	96.1 est.
Q4	8K default	18.38 GB	No	93.0 est.
Q4	32K	20.18 GB	No	77.2 est.
FP16	4K	62.3 GB	No	—
FP16	8K default	62.6 GB	No	—
FP16	32K	64.4 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).
