Yes — here's how fast and up to what context, with real measured numbers.
MADLAD-400 10B on the Apple M2 Max 64GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 212k | 12.7-15.3 t/s | ~0.3-0.4 (slow) |
| Q8 | yes | 277k | 25.4-30.7 t/s | ~0.6-0.8 (slow) |
| Q4 | yes | 306k | 45.4-54.7 t/s | ~1.1-1.4 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
