Can the NVIDIA B200 run CausalLM 14B?

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

CausalLM 14B on the NVIDIA B200

QuantFits?Max contextSpeedBeyond context
FP16 yes 890k 198.6-236.7 t/s ~1-1.2 (slow)
Q8 yes 979k 397.3-473.5 t/s ~2-2.4 (slow)
Q4 yes 1019k 709.4-845.5 t/s ~3.5-4.2 (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 CausalLM 14B?โ–ถ

Yes. At Q4 it generates ~709.4-845.5 tok/s and fits up to 1019k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~3.5-4.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1019k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
