Yes — the DGX Spark (GH200 480GB) (480 GB LPDDR5X) can run Qwen3-Coder-480B-A35B-Instruct. At Q4 with the default 8K context it needs ≈ 272.11 GB VRAM (weights 264.11 GB + KV cache 7.0 GB + 1 GB runtime overhead), which fits within 480 GB. Decode at Q4/8K: ≈ 9.1 tok/s (estimated, batch 1). 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.

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).
