Can the AMD Ryzen AI Max+ 395 run OPT-1.3B?
Yes — here's how fast and up to what context, with real measured numbers.
OPT-1.3B on the AMD Ryzen AI Max+ 395
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1695k | 62-75.8 t/s | ~2.4-3 (slow) |
| Q8 | yes | 1715k | 124.1-151.6 t/s | ~4.8-5.9 (slow) |
| Q4 | yes | 1724k | 221.5-270.8 t/s | ~8.7-10.6 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
