Yes — here's how fast and up to what context, with real measured numbers.
HiFi - NN on the Apple M1 Max 32GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 416k | 45333.3-54666.7 t/s | ~1133.3-1366.7 (slow) |
| Q8 | yes | 417k | 90666.7-109333.3 t/s | ~2266.7-2733.3 (slow) |
| Q4 | yes | 417k | 161904.8-195238.1 t/s | ~4047.6-4881 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
