Can the NVIDIA B200 run Mixtral 8x22B?

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

Q8 yes 104k 41.4-49.4 t/s ~0.2-0.2 (slow)
Q4 yes 294k 74-88.1 t/s ~0.4-0.4 (slow)

Estimate (memory-bound). Beyond "max context" the KV cache spills to system RAM offload (depends on your system RAM) and speed drops to the "beyond" figure.

FAQ

Can the NVIDIA B200 run Mixtral 8x22B?โ–ถ

Yes. At Q4 it generates ~74-88.1 tok/s and fits up to 294k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.4-0.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 294k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
