Can DGX Spark (GH200 480GB) run DeepSeek-R1?

NVIDIA · 480 GB LPDDR5X · 500 GB/s bandwidth · DeepSeek · 684.5B (active 37B) · MoE · model ctx up to 128K

CUDA

Yes — the DGX Spark (GH200 480GB) (480 GB LPDDR5X) can run DeepSeek-R1. At Q4 with the default 8K context it needs ≈ 378.4 GB VRAM (weights 376.48 GB + KV cache 0.93 GB + 1 GB runtime overhead), which fits within 480 GB. Decode at Q4/8K: ≈ 8.6 tok/s (estimated, batch 1). FP16 needs ≈ 1370.92 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.

Fit & speed by quant and context

Quant	Context	VRAM needed	Fits?	tok/s (decode)
Q4	4K	377.94 GB	Yes	8.6 ± est.
Q4	8K default	378.4 GB	Yes	8.6 ± est.
Q4	32K	381.18 GB	Yes	8.6 ± est.
FP16	4K	1370.46 GB	No	0.8 ± est.
FP16	8K default	1370.92 GB	No	0.8 ± est.
FP16	32K	1373.7 GB	No	0.8 ± 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).
