Can the NVIDIA DGX Spark run K2 Think?
Yes โ here's how fast and up to what context, with real measured numbers.
K2 Think on the NVIDIA DGX Spark
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 190k | 3.1-3.7 t/s | ~0.1-0.1 (slow) |
| Q8 | yes | 312k | 6.2-7.4 t/s | ~0.2-0.3 (slow) |
| Q4 | yes | 365k | 11.1-13.3 t/s | ~0.4-0.5 (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 K2 Think?โถ
Yes. At Q4 it generates ~11.1-13.3 tok/s and fits up to 365k context; beyond that it spills to SSD swap and slows to ~0.4-0.5 tok/s.
How much context fits?โถ
At Q4, up to about 365k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
