Can the NVIDIA B200 run DBRX?

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

DBRX on the NVIDIA B200

Q8 yes 132k 44.2-52.7 t/s ~0.2-0.3 (slow)
Q4 yes 309k 79-94.2 t/s ~0.4-0.5 (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 DBRX?โ–ถ

Yes. At Q4 it generates ~79-94.2 tok/s and fits up to 309k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.4-0.5 tok/s.

How much context fits?โ–ถ

At Q4, up to about 309k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
