Yes — here's how fast and up to what context, with real measured numbers.
BART-IT on the Apple M2 Max 64GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 852k | 971.4-1171.4 t/s | ~24.3-29.3 (slow) |
| Q8 | yes | 854k | 1942.9-2342.9 t/s | ~48.6-58.6 (slow) |
| Q4 | yes | 855k | 3469.4-4183.7 t/s | ~86.7-104.6 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
