Can the Apple M4 Max 48GB run RWKV-5 (Eagle) 7B?
Yes — here's how fast and up to what context, with real measured numbers.
RWKV-5 (Eagle) 7B on the Apple M4 Max 48GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 203k | 24.7-29.8 t/s | ~0.5-0.5 (slow) |
| Q8 | yes | 261k | 49.4-59.5 t/s | ~0.9-1.1 (slow) |
| Q4 | yes | 286k | 88.2-106.3 t/s | ~1.6-1.9 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
