Yes — here's how fast and up to what context, with real measured numbers.
BART-IT on the Apple M4 Max 48GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 632k | 1326-1599 t/s | ~24.3-29.3 (slow) |
| Q8 | yes | 634k | 2652-3198 t/s | ~48.6-58.6 (slow) |
| Q4 | yes | 635k | 4735.7-5710.7 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.
