Can RTX 4070 Ti 12GB run Qwen3-32B?

NVIDIA · 12 GB GDDR6X · 554 GB/s bandwidth · Alibaba · 32.8B · model ctx up to 128K

No — Qwen3-32B at Q4 needs ≈ 22.32 GB even at 4K context, beyond the RTX 4070 Ti 12GB's 12 GB GDDR6X. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 6.7 tok/s (estimated, batch 1). FP16 needs ≈ 73.16 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	22.32 GB	No	8.9 est.
Q4	8K default	25.6 GB	No	6.7 est.
Q4	32K	45.28 GB	No	2.2 est.
FP16	4K	69.88 GB	No	—
FP16	8K default	73.16 GB	No	—
FP16	32K	92.84 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).
