Can RTX 5070 12GB run Qwen3.5-35B-A3B?

NVIDIA · 12 GB GDDR7 · 672 GB/s bandwidth · Alibaba · 34.7B (active 3.0B) · MoE · model ctx up to 256K

No — Qwen3.5-35B-A3B at Q4 needs ≈ 20.39 GB even at 4K context, beyond the RTX 5070 12GB's 12 GB GDDR7. It would only run with heavy CPU/disk offload. Decode at Q4/8K: ≈ 137.0 tok/s (estimated, batch 1). FP16 needs ≈ 71.0 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	20.39 GB	No	141.1 est.
Q4	8K default	20.69 GB	No	137.0 est.
Q4	32K	22.49 GB	No	115.9 est.
FP16	4K	70.7 GB	No	—
FP16	8K default	71.0 GB	No	—
FP16	32K	72.8 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).
