Yes — here's how fast and up to what context, with real measured numbers.
Refact-1.6B on the NVIDIA RTX PRO 6000 Blackwell
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1276k | 408.8-487.2 t/s | ~9.1-10.9 (slow) |
| Q8 | yes | 1300k | 817.6-974.4 t/s | ~18.3-21.8 (slow) |
| Q4 | yes | 1311k | 1460-1740 t/s | ~32.6-38.8 (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.
