Can the Apple M2 Max 64GB run InternVL2_5-38B?
Yes — here's how fast and up to what context, with real measured numbers.
InternVL2_5-38B on the Apple M2 Max 64GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | no | — | — | — |
| Q8 | yes | 68k | 7.1-8.5 t/s | ~0.2-0.2 (slow) |
| Q4 | yes | 132k | 12.6-15.3 t/s | ~0.3-0.4 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
