QuantFits?Max contextSpeedBeyond context
FP16 yes 1720k 199.3-237.5 t/s ~7.3-8.7 (slow)
Q8 yes 1727k 398.6-475 t/s ~14.6-17.4 (slow)
Q4 yes 1731k 711.8-848.3 t/s ~26.1-31.1 (slow)

Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.

FAQ

Can the NVIDIA DGX Spark run Spec-Drafter?โ–ถ

Yes. At Q4 it generates ~711.8-848.3 tok/s and fits up to 1731k context; beyond that it spills to SSD swap and slows to ~26.1-31.1 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1731k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
