Domyn Small on the Apple M1 Ultra 128GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 572k | 27.2-32.8 t/s | ~0.3-0.4 (slow) |
| Q8 | yes | 633k | 54.4-65.6 t/s | ~0.7-0.8 (slow) |
| Q4 | yes | 660k | 97.1-117.1 t/s | ~1.2-1.5 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
