Can the Apple M3 Max 64GB run OpenELM-3B?
Yes — here's how fast and up to what context, with real measured numbers.
OpenELM-3B on the Apple M3 Max 64GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 763k | 44.7-53.9 t/s | ~1.1-1.3 (slow) |
| Q8 | yes | 810k | 89.5-107.9 t/s | ~2.2-2.7 (slow) |
| Q4 | yes | 830k | 159.8-192.7 t/s | ~4-4.8 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
