Can the NVIDIA DGX Spark run ALiBi (L=3072, Lvalid = 3072)?
Yes — here's how fast and up to what context, with real measured numbers.
ALiBi (L=3072, Lvalid = 3072) on the NVIDIA DGX Spark
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1695k | 76.7-91.4 t/s | ~2.8-3.3 (slow) |
| Q8 | yes | 1715k | 153.3-182.7 t/s | ~5.6-6.7 (slow) |
| Q4 | yes | 1724k | 273.8-326.3 t/s | ~10-12 (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 ALiBi (L=3072, Lvalid = 3072)?▶
Yes. At Q4 it generates ~273.8-326.3 tok/s and fits up to 1724k context; beyond that it spills to SSD swap and slows to ~10-12 tok/s.
How much context fits?▶
At Q4, up to about 1724k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
