XLNet on the Apple M2 Ultra 64GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 846k | 800-964.7 t/s | ~10-12.1 (slow) |
| Q8 | yes | 851k | 1600-1929.4 t/s | ~20-24.1 (slow) |
| Q4 | yes | 853k | 2857.1-3445.4 t/s | ~35.7-43.1 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
