Can the AMD Ryzen AI Max+ 395 run GPT-2 (774M)?
Yes — here's how fast and up to what context, with real measured numbers.
GPT-2 (774M) on the AMD Ryzen AI Max+ 395
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1711k | 104.2-127.3 t/s | ~4.1-5 (slow) |
| Q8 | yes | 1723k | 208.4-254.7 t/s | ~8.1-9.9 (slow) |
| Q4 | yes | 1728k | 372.1-454.8 t/s | ~14.5-17.8 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to SSD swap and speed drops to the "beyond" figure.
FAQ
Can the AMD Ryzen AI Max+ 395 run GPT-2 (774M)?▶
Yes. At Q4 it generates ~372.1-454.8 tok/s and fits up to 1728k context; beyond that it spills to SSD swap and slows to ~14.5-17.8 tok/s.
How much context fits?▶
At Q4, up to about 1728k tokens stay in fast memory; longer context spills to SSD swap and throughput collapses.
