Can the Apple M3 Max 128GB run Pythia-160m?
Yes — here's how fast and up to what context, with real measured numbers.
Pythia-160m on the Apple M3 Max 128GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1730k | 850-1025 t/s | ~21.3-25.6 (slow) |
| Q8 | yes | 1732k | 1700-2050 t/s | ~42.5-51.3 (slow) |
| Q4 | yes | 1734k | 3035.7-3660.7 t/s | ~75.9-91.5 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
FAQ
Can the Apple M3 Max 128GB run Pythia-160m?▶
Yes. At Q4 it generates ~3035.7-3660.7 tok/s and fits up to 1734k context; beyond that it spills to SSD swap and slows to ~75.9-91.5 tok/s.
How much context fits?▶
At Q4, up to about 1734k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
