StyleGAN3-T on the Apple M2 Ultra 192GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2614k | 121973.1-147085.2 t/s | ~1524.7-1838.6 (slow) |
| Q8 | yes | 2614k | 243946.2-294170.4 t/s | ~3049.3-3677.1 (slow) |
| Q4 | yes | 2614k | 435618.2-525304.3 t/s | ~5445.2-6566.3 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
