Engine-Medium(NE) on the Apple M2 Ultra 192GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2603k | 766.2-923.9 t/s | ~9.6-11.5 (slow) |
| Q8 | yes | 2608k | 1532.4-1847.9 t/s | ~19.2-23.1 (slow) |
| Q4 | yes | 2611k | 2736.4-3299.8 t/s | ~34.2-41.2 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
