Can the Apple M3 Max 128GB run Earth-2 (cBottle-SR)?
Yes — here's how fast and up to what context, with real measured numbers.
Earth-2 (cBottle-SR) on the Apple M3 Max 128GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1725k | 412.1-497 t/s | ~10.3-12.4 (slow) |
| Q8 | yes | 1730k | 824.2-993.9 t/s | ~20.6-24.8 (slow) |
| Q4 | yes | 1732k | 1471.9-1774.9 t/s | ~36.8-44.4 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
