Yes — here's how fast and up to what context, with real measured numbers.
Japanese-LM-3.6B on the Apple M4 Max 64GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 746k | 51.6-62.2 t/s | ~0.9-1.1 (slow) |
| Q8 | yes | 801k | 103.1-124.4 t/s | ~1.9-2.3 (slow) |
| Q4 | yes | 825k | 184.2-222.1 t/s | ~3.4-4.1 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
