AntiFormer on the Apple M1 Max 64GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 855k | 5512.6-6647.6 t/s | ~137.8-166.2 (slow) |
| Q8 | yes | 856k | 11025.3-13295.2 t/s | ~275.6-332.4 (slow) |
| Q4 | yes | 856k | 19688-23741.4 t/s | ~492.2-593.5 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
