Can the Apple M4 Max 64GB run MiniCPM-2.4B?
Yes — here's how fast and up to what context, with real measured numbers.
MiniCPM-2.4B on the Apple M4 Max 64GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 781k | 76-91.7 t/s | ~1.4-1.7 (slow) |
| Q8 | yes | 819k | 152-183.3 t/s | ~2.8-3.4 (slow) |
| Q4 | yes | 835k | 271.5-327.4 t/s | ~5-6 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
