Can L40S 48GB run MiniCPM5-1B?

NVIDIA · 48 GB GDDR6 · 864 GB/s bandwidth · OpenBMB · 1.08B · model ctx up to 128K

Yes — the L40S 48GB (48 GB GDDR6) can run MiniCPM5-1B. At Q4 with the default 8K context it needs ≈ 1.81 GB VRAM (weights 0.59 GB + KV cache 0.22 GB + 1 GB runtime overhead), which fits within 48 GB. Decode at Q4/8K: ≈ 509.1 tok/s (estimated, batch 1). FP16 (≈ 3.38 GB) also fits, at ≈ 140.0 tok/s (estimated). 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	1.7 GB	Yes	509.1 est.
Q4	8K default	1.81 GB	Yes	509.1 est.
Q4	32K	2.46 GB	Yes	509.1 est.
FP16	4K	3.27 GB	Yes	140.0 est.
FP16	8K default	3.38 GB	Yes	140.0 est.
FP16	32K	4.02 GB	Yes	140.0 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).
