Can the NVIDIA DGX Spark run Routing Transformer (WT-103)?
Yes — here's how fast and up to what context, with real measured numbers.
Routing Transformer (WT-103) on the NVIDIA DGX Spark
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1732k | 1253.4-1493.8 t/s | ~45.9-54.7 (slow) |
| Q8 | yes | 1734k | 2506.8-2987.5 t/s | ~91.8-109.4 (slow) |
| Q4 | yes | 1734k | 4476.4-5334.9 t/s | ~164-195.4 (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 Routing Transformer (WT-103)?▶
Yes. At Q4 it generates ~4476.4-5334.9 tok/s and fits up to 1734k context; beyond that it spills to SSD swap and slows to ~164-195.4 tok/s.
How much context fits?▶
At Q4, up to about 1734k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
