MULAN on the Apple M2 Ultra 64GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 855k | 7771.4-9371.4 t/s | ~97.1-117.1 (slow) |
| Q8 | yes | 855k | 15542.9-18742.9 t/s | ~194.3-234.3 (slow) |
| Q4 | yes | 856k | 27755.1-33469.4 t/s | ~346.9-418.4 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
