Can the AMD Radeon RX 7800 XT run OPT-125M (finetuned on PTB)?
Yes — here's how fast and up to what context, with real measured numbers.
OPT-125M (finetuned on PTB) on the AMD Radeon RX 7800 XT
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 198k | 1572.5-1921.9 t/s | ~100.8-123.2 (slow) |
| Q8 | yes | 200k | 3145-3843.8 t/s | ~201.6-246.4 (slow) |
| Q4 | yes | 201k | 5616-6864 t/s | ~360-440 (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 RX 7800 XT run OPT-125M (finetuned on PTB)?▶
Yes. At Q4 it generates ~5616-6864 tok/s and fits up to 201k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~360-440 tok/s.
How much context fits?▶
At Q4, up to about 201k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
