Can the NVIDIA DGX Spark run ProtBERT-BFD?
Yes — here's how fast and up to what context, with real measured numbers.
ProtBERT-BFD on the NVIDIA DGX Spark
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1722k | 237.3-282.8 t/s | ~8.7-10.4 (slow) |
| Q8 | yes | 1729k | 474.5-565.5 t/s | ~17.4-20.7 (slow) |
| Q4 | yes | 1731k | 847.3-1009.8 t/s | ~31-37 (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 ProtBERT-BFD?▶
Yes. At Q4 it generates ~847.3-1009.8 tok/s and fits up to 1731k context; beyond that it spills to SSD swap and slows to ~31-37 tok/s.
How much context fits?▶
At Q4, up to about 1731k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
