Can L40S 48GB run Qwen3.6-35B-A3B?

Yes — the L40S 48GB (48 GB GDDR6) can run Qwen3.6-35B-A3B. At Q4 with the default 8K context it needs ≈ 21.4 GB VRAM (weights 19.8 GB + KV cache 0.6 GB + 1 GB runtime overhead), which fits within 48 GB. Decode at Q4/8K: ≈ 183.3 tok/s (estimated, batch 1). FP16 needs ≈ 73.6 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	21.1 GB	Yes	183.3 est.
Q4	8K default	21.4 GB	Yes	183.3 est.
Q4	32K	23.2 GB	Yes	183.3 est.
FP16	4K	73.3 GB	No	61.8 est.
FP16	8K default	73.6 GB	No	61.2 est.
FP16	32K	75.4 GB	No	58.4 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).
