Can the NVIDIA L40S 48GB run Qwen-Audio-Chat?
Yes — here's how fast and up to what context, with real measured numbers.
Qwen-Audio-Chat on the NVIDIA L40S 48GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 196k | 37.3-44.4 t/s | ~1.7-2.1 (slow) |
| Q8 | yes | 261k | 74.6-88.9 t/s | ~3.5-4.1 (slow) |
| Q4 | yes | 289k | 133.1-158.7 t/s | ~6.2-7.3 (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.
