Can the Apple M3 Max 36GB run Refact-1.6B?
Yes — here's how fast and up to what context, with real measured numbers.
Refact-1.6B on the Apple M3 Max 36GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 423k | 63.8-76.9 t/s | ~2.1-2.6 (slow) |
| Q8 | yes | 447k | 127.5-153.8 t/s | ~4.3-5.1 (slow) |
| Q4 | yes | 458k | 227.7-274.6 t/s | ~7.6-9.2 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
