ESM1-43M on the Apple M2 Ultra 192GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2613k | 6385-7699.5 t/s | ~79.8-96.2 (slow) |
| Q8 | yes | 2613k | 12770-15399.1 t/s | ~159.6-192.5 (slow) |
| Q4 | yes | 2613k | 22803.5-27498.3 t/s | ~285-343.7 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
