Can the NVIDIA DGX Spark run HiFi - NN?
Yes — here's how fast and up to what context, with real measured numbers.
HiFi - NN on the NVIDIA DGX Spark
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1735k | 33215-39585 t/s | ~1216.7-1450 (slow) |
| Q8 | yes | 1735k | 66430-79170 t/s | ~2433.3-2900 (slow) |
| Q4 | yes | 1735k | 118625-141375 t/s | ~4345.2-5178.6 (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 HiFi - NN?▶
Yes. At Q4 it generates ~118625-141375 tok/s and fits up to 1735k context; beyond that it spills to SSD swap and slows to ~4345.2-5178.6 tok/s.
How much context fits?▶
At Q4, up to about 1735k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
