Can the Apple M2 Ultra 64GB run Minitron 8B?
Yes — here's how fast and up to what context, with real measured numbers.
Minitron 8B on the Apple M2 Ultra 64GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 301k | 32.8-39.5 t/s | ~0.4-0.5 (slow) |
| Q8 | yes | 365k | 65.5-79 t/s | ~0.8-1 (slow) |
| Q4 | yes | 393k | 117-141.1 t/s | ~1.5-1.8 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
