Can the Apple M2 Max 32GB run Refact-1.6B?
Yes โ here's how fast and up to what context, with real measured numbers.
Refact-1.6B on the Apple M2 Max 32GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 368k | 85-102.5 t/s | ~2.1-2.6 (slow) |
| Q8 | yes | 392k | 170-205 t/s | ~4.3-5.1 (slow) |
| Q4 | yes | 403k | 303.6-366.1 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.
