TinyBert on the Apple M1 Ultra 128GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1733k | 4059.7-4895.5 t/s | ~50.7-61.2 (slow) |
| Q8 | yes | 1734k | 8119.4-9791 t/s | ~101.5-122.4 (slow) |
| Q4 | yes | 1734k | 14498.9-17484 t/s | ~181.2-218.6 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
