Can the Apple M4 Max 48GB run Playground v2.5?
Yes — here's how fast and up to what context, with real measured numbers.
Playground v2.5 on the Apple M4 Max 48GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 529k | 53-64 t/s | ~1-1.2 (slow) |
| Q8 | yes | 583k | 106.1-127.9 t/s | ~1.9-2.3 (slow) |
| Q4 | yes | 606k | 189.4-228.4 t/s | ~3.5-4.2 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
