Can the NVIDIA L40S 48GB run OpenPhenom-S/16?
Yes — here's how fast and up to what context, with real measured numbers.
OpenPhenom-S/16 on the NVIDIA L40S 48GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 646k | 1771.2-2110.9 t/s | ~82-97.7 (slow) |
| Q8 | yes | 648k | 3542.5-4221.8 t/s | ~164-195.5 (slow) |
| Q4 | yes | 649k | 6325.8-7539 t/s | ~292.9-349 (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 L40S 48GB run OpenPhenom-S/16?▶
Yes. At Q4 it generates ~6325.8-7539 tok/s and fits up to 649k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~292.9-349 tok/s.
How much context fits?▶
At Q4, up to about 649k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
