Yi 6B on the Apple M1 Max 64GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 336k | 22.7-27.3 t/s | ~0.6-0.7 (slow) |
| Q8 | yes | 382k | 45.3-54.7 t/s | ~1.1-1.4 (slow) |
| Q4 | yes | 402k | 81-97.6 t/s | ~2-2.4 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
