RMBG v2.0 on the Apple M2 Ultra 192GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2607k | 1230.8-1484.2 t/s | ~15.4-18.6 (slow) |
| Q8 | yes | 2610k | 2461.5-2968.3 t/s | ~30.8-37.1 (slow) |
| Q4 | yes | 2612k | 4395.6-5300.6 t/s | ~54.9-66.3 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
