Can the NVIDIA B200 run LUXIA-21.4B-Alignment?
Yes — here's how fast and up to what context, with real measured numbers.
LUXIA-21.4B-Alignment on the NVIDIA B200
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 505k | 136.4-162.6 t/s | ~0.7-0.8 (slow) |
| Q8 | yes | 586k | 272.9-325.2 t/s | ~1.4-1.6 (slow) |
| Q4 | yes | 622k | 487.3-580.8 t/s | ~2.4-2.9 (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 LUXIA-21.4B-Alignment?▶
Yes. At Q4 it generates ~487.3-580.8 tok/s and fits up to 622k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~2.4-2.9 tok/s.
How much context fits?▶
At Q4, up to about 622k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
