Can L40S 48GB run Qwen3-Coder-480B-A35B-Instruct?

NVIDIA · 48 GB GDDR6 · 864 GB/s bandwidth · Alibaba · 480.2B (active 35B) · MoE · model ctx up to 256K

No — Qwen3-Coder-480B-A35B-Instruct at Q4 needs ≈ 268.61 GB even at 4K context, beyond the L40S 48GB's 48 GB GDDR6. It would only run with heavy CPU/disk offload. FP16 needs ≈ 968.4 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	268.61 GB	No	—
Q4	8K default	272.11 GB	No	—
Q4	32K	293.11 GB	No	—
FP16	4K	964.9 GB	No	—
FP16	8K default	968.4 GB	No	—
FP16	32K	989.4 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).
