Can the AMD Radeon RX 7900 XTX run 6-Act Tether?
Yes — here's how fast and up to what context, with real measured numbers.
6-Act Tether on the AMD Radeon RX 7900 XTX
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 314k | 60480-73920 t/s | ~2520-3080 (slow) |
| Q8 | yes | 314k | 120960-147840 t/s | ~5040-6160 (slow) |
| Q4 | yes | 314k | 216000-264000 t/s | ~9000-11000 (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 7900 XTX run 6-Act Tether?▶
Yes. At Q4 it generates ~216000-264000 tok/s and fits up to 314k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~9000-11000 tok/s.
How much context fits?▶
At Q4, up to about 314k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
