Can the AMD Ryzen AI Max+ 395 run Qwen2.5-Coder (1.5B)?
Yes — here's how fast and up to what context, with real measured numbers.
Qwen2.5-Coder (1.5B) on the AMD Ryzen AI Max+ 395
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1688k | 52.4-64 t/s | ~2-2.5 (slow) |
| Q8 | yes | 1711k | 104.7-128 t/s | ~4.1-5 (slow) |
| Q4 | yes | 1722k | 187-228.6 t/s | ~7.3-8.9 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
