Can the AMD Radeon Pro W7900 48GB run Spec-Drafter?
Yes — here's how fast and up to what context, with real measured numbers.
Spec-Drafter on the AMD Radeon Pro W7900 48GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 636k | 544.3-665.3 t/s | ~25.2-30.8 (slow) |
| Q8 | yes | 643k | 1088.6-1330.6 t/s | ~50.4-61.6 (slow) |
| Q4 | yes | 647k | 1944-2376 t/s | ~90-110 (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.
