Can the NVIDIA DGX Spark run Qwen3-1.7B?
Yes — here's how fast and up to what context, with real measured numbers.
Qwen3-1.7B on the NVIDIA DGX Spark
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1683k | 58.6-69.9 t/s | ~2.1-2.6 (slow) |
| Q8 | yes | 1709k | 117.2-139.7 t/s | ~4.3-5.1 (slow) |
| Q4 | yes | 1720k | 209.3-249.5 t/s | ~7.7-9.1 (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 Qwen3-1.7B?▶
Yes. At Q4 it generates ~209.3-249.5 tok/s and fits up to 1720k context; beyond that it spills to SSD swap and slows to ~7.7-9.1 tok/s.
How much context fits?▶
At Q4, up to about 1720k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
