Can the NVIDIA DGX Spark run S4?
Yes — here's how fast and up to what context, with real measured numbers.
S4 on the NVIDIA DGX Spark
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1727k | 400.2-476.9 t/s | ~14.7-17.5 (slow) |
| Q8 | yes | 1731k | 800.4-953.9 t/s | ~29.3-34.9 (slow) |
| Q4 | yes | 1733k | 1429.2-1703.3 t/s | ~52.4-62.4 (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 S4?▶
Yes. At Q4 it generates ~1429.2-1703.3 tok/s and fits up to 1733k context; beyond that it spills to SSD swap and slows to ~52.4-62.4 tok/s.
How much context fits?▶
At Q4, up to about 1733k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
