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 xLAM-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.
