Can the AMD Radeon Pro W7900 48GB run Pythia-410m?
Yes — here's how fast and up to what context, with real measured numbers.
Pythia-410m on the AMD Radeon Pro W7900 48GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 638k | 663.8-811.3 t/s | ~30.7-37.6 (slow) |
| Q8 | yes | 645k | 1327.6-1622.6 t/s | ~61.5-75.1 (slow) |
| Q4 | yes | 647k | 2370.7-2897.6 t/s | ~109.8-134.1 (slow) |
Estimate (memory-bound). Beyond "max context" the KV cache spills to system RAM offload (depends on your system RAM) and speed drops to the "beyond" figure.
FAQ
Can the AMD Radeon Pro W7900 48GB run Pythia-410m?▶
Yes. At Q4 it generates ~2370.7-2897.6 tok/s and fits up to 647k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~109.8-134.1 tok/s.
How much context fits?▶
At Q4, up to about 647k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
