Can the NVIDIA DGX Spark run MegaMolBART?
Yes — here's how fast and up to what context, with real measured numbers.
MegaMolBART on the NVIDIA DGX Spark
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1734k | 2214.3-2639 t/s | ~81.1-96.7 (slow) |
| Q8 | yes | 1734k | 4428.7-5278 t/s | ~162.2-193.3 (slow) |
| Q4 | yes | 1735k | 7908.3-9425 t/s | ~289.7-345.2 (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 MegaMolBART?▶
Yes. At Q4 it generates ~7908.3-9425 tok/s and fits up to 1735k context; beyond that it spills to SSD swap and slows to ~289.7-345.2 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.
