Can the NVIDIA DGX Spark run minChatGPT?
Yes — here's how fast and up to what context, with real measured numbers.
minChatGPT on the NVIDIA DGX Spark
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1685k | 60.8-72.5 t/s | ~2.2-2.7 (slow) |
| Q8 | yes | 1710k | 121.6-144.9 t/s | ~4.5-5.3 (slow) |
| Q4 | yes | 1721k | 217.1-258.8 t/s | ~8-9.5 (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 minChatGPT?▶
Yes. At Q4 it generates ~217.1-258.8 tok/s and fits up to 1721k context; beyond that it spills to SSD swap and slows to ~8-9.5 tok/s.
How much context fits?▶
At Q4, up to about 1721k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
