Can the NVIDIA DGX Spark run Qwen-72B?

Yes โ€” here's how fast and up to what context, with real measured numbers.

Q8 yes 127k 2.8-3.3 t/s ~0.1-0.1 (slow)
Q4 yes 224k 4.9-5.9 t/s ~0.2-0.2 (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 Qwen-72B?โ–ถ

Yes. At Q4 it generates ~4.9-5.9 tok/s and fits up to 224k context; beyond that it spills to SSD swap and slows to ~0.2-0.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 224k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
