Aria on the Apple M1 Ultra 128GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 244k | 10.9-13.2 t/s | ~0.1-0.2 (slow) |
| Q8 | yes | 339k | 21.8-26.3 t/s | ~0.3-0.3 (slow) |
| Q4 | yes | 381k | 39-47 t/s | ~0.5-0.6 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
