Can the Apple M3 Max 36GB run iGPT-L?
Yes — here's how fast and up to what context, with real measured numbers.
iGPT-L on the Apple M3 Max 36GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 430k | 74.9-90.3 t/s | ~2.5-3 (slow) |
| Q8 | yes | 451k | 149.8-180.6 t/s | ~5-6 (slow) |
| Q4 | yes | 460k | 267.5-322.5 t/s | ~8.9-10.8 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
