Can the Apple M3 Max 36GB run BLOOM-7.1B?
Yes โ here's how fast and up to what context, with real measured numbers.
BLOOM-7.1B on the Apple M3 Max 36GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 128k | 14.4-17.4 t/s | ~0.5-0.6 (slow) |
| Q8 | yes | 182k | 28.9-34.8 t/s | ~1-1.2 (slow) |
| Q4 | yes | 206k | 51.5-62.1 t/s | ~1.7-2.1 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
FAQ
