Can the AMD Radeon RX 6900 XT run Zagreus 0.4B?
Yes — here's how fast and up to what context, with real measured numbers.
Zagreus 0.4B on the AMD Radeon RX 6900 XT
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 190k | 403.2-492.8 t/s | ~31.5-38.5 (slow) |
| Q8 | yes | 196k | 806.4-985.6 t/s | ~63-77 (slow) |
| Q4 | yes | 198k | 1440-1760 t/s | ~112.5-137.5 (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 6900 XT run Zagreus 0.4B?▶
Yes. At Q4 it generates ~1440-1760 tok/s and fits up to 198k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~112.5-137.5 tok/s.
How much context fits?▶
At Q4, up to about 198k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
