Yes — here's how fast and up to what context, with real measured numbers.
ERNIE-4.5-0.3B on the Apple M4 Max 48GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 625k | 515.7-621.8 t/s | ~9.4-11.4 (slow) |
| Q8 | yes | 631k | 1031.3-1243.7 t/s | ~18.9-22.8 (slow) |
| Q4 | yes | 633k | 1841.7-2220.8 t/s | ~33.7-40.7 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
