Can the NVIDIA DGX Spark run Phi-4 Mini?
Yes — here's how fast and up to what context, with real measured numbers.
Phi-4 Mini on the NVIDIA DGX Spark
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1619k | 26.2-31.3 t/s | ~1-1.1 (slow) |
| Q8 | yes | 1677k | 52.4-62.5 t/s | ~1.9-2.3 (slow) |
| Q4 | yes | 1702k | 93.7-111.6 t/s | ~3.4-4.1 (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 Phi-4 Mini?▶
Yes. At Q4 it generates ~93.7-111.6 tok/s and fits up to 1702k context; beyond that it spills to SSD swap and slows to ~3.4-4.1 tok/s.
How much context fits?▶
At Q4, up to about 1702k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
