Can RTX 5070 Ti 16GB run Qwen3-30B-A3B-Instruct-2507?

NVIDIA · 16 GB GDDR7 · 896 GB/s bandwidth · Alibaba · 30.5B (active 3B) · MoE · model ctx up to 256K

No — Qwen3-30B-A3B-Instruct-2507 at Q4 needs ≈ 18.08 GB even at 4K context, beyond the RTX 5070 Ti 16GB's 16 GB GDDR7. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 411.5 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	425.3 est.
Q4	8K default	18.38 GB	No	411.5 est.
Q4	32K	20.18 GB	No	341.4 est.
FP16	4K	62.3 GB	No	9.8 est.
FP16	8K default	62.6 GB	No	9.8 est.
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).
