Can the AMD Ryzen AI Max+ 395 run GPT-Neo-125M?
Yes — here's how fast and up to what context, with real measured numbers.
GPT-Neo-125M on the AMD Ryzen AI Max+ 395
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1731k | 645.1-788.5 t/s | ~25.2-30.8 (slow) |
| Q8 | yes | 1733k | 1290.2-1577 t/s | ~50.4-61.6 (slow) |
| Q4 | yes | 1734k | 2304-2816 t/s | ~90-110 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
FAQ
