Can the NVIDIA DGX Spark run Granite 3.1 8B?
Yes — here's how fast and up to what context, with real measured numbers.
Granite 3.1 8B on the NVIDIA DGX Spark
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 744k | 12.3-14.7 t/s | ~0.5-0.5 (slow) |
| Q8 | yes | 806k | 24.6-29.3 t/s | ~0.9-1.1 (slow) |
| Q4 | yes | 833k | 43.9-52.4 t/s | ~1.6-1.9 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
FAQ
