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 Mixtral 8x22B?โ–ถ

Yes. At Q4 it generates ~2.5-3 tok/s and fits up to 106k context; beyond that it spills to SSD swap and slows to ~0.1-0.1 tok/s.

How much context fits?โ–ถ

At Q4, up to about 106k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
