Can the NVIDIA DGX Spark run XVERSE-MoE-A4.2B?
Yes — here's how fast and up to what context, with real measured numbers.
XVERSE-MoE-A4.2B on the NVIDIA DGX Spark
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1607k | 23.7-28.3 t/s | ~0.9-1 (slow) |
| Q8 | yes | 1671k | 47.5-56.6 t/s | ~1.7-2.1 (slow) |
| Q4 | yes | 1699k | 84.7-101 t/s | ~3.1-3.7 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
