TRIMELMext (7M) on the Apple M1 Ultra 128GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1735k | 38857.1-46857.1 t/s | ~485.7-585.7 (slow) |
| Q8 | yes | 1735k | 77714.3-93714.3 t/s | ~971.4-1171.4 (slow) |
| Q4 | yes | 1735k | 138775.5-167346.9 t/s | ~1734.7-2091.8 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
