Yes — here's how fast and up to what context, with real measured numbers.
Qwen2.5-Coder (7B) on the Apple M1 Ultra 64GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 312k | 35.7-43.1 t/s | ~0.4-0.5 (slow) |
| Q8 | yes | 370k | 71.5-86.2 t/s | ~0.9-1.1 (slow) |
| Q4 | yes | 395k | 127.7-153.9 t/s | ~1.6-1.9 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
