Can the NVIDIA B200 run GRITLM 8x7B?

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

GRITLM 8x7B on the NVIDIA B200

QuantFits?Max contextSpeedBeyond context
FP16 yes 249k 62.5-74.5 t/s ~0.3-0.4 (slow)
Q8 yes 392k 125.1-149 t/s ~0.6-0.7 (slow)
Q4 yes 455k 223.3-266.1 t/s ~1.1-1.3 (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 GRITLM 8x7B?โ–ถ

Yes. At Q4 it generates ~223.3-266.1 tok/s and fits up to 455k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~1.1-1.3 tok/s.

How much context fits?โ–ถ

At Q4, up to about 455k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
