// RUN — FITS
Can the Apple M1 Max 64GB run Mamba2-Hybrid?
Yes — here's how fast and up to what context, with real measured numbers.
Mamba2-Hybrid on the Apple M1 Max 64GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 296k | 15.7-18.9 t/s | ~0.4-0.5 (slow) |
| Q8 | yes | 362k | 31.4-37.9 t/s | ~0.8-0.9 (slow) |
| Q4 | yes | 391k | 56.1-67.6 t/s | ~1.4-1.7 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
