Can the AMD Radeon RX 7900 XT run Ankh_base?
Yes — here's how fast and up to what context, with real measured numbers.
Ankh_base on the AMD Radeon RX 7900 XT
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 235k | 340.5-416.2 t/s | ~17-20.8 (slow) |
| Q8 | yes | 247k | 681.1-832.4 t/s | ~34.1-41.6 (slow) |
| Q4 | yes | 252k | 1216.2-1486.5 t/s | ~60.8-74.3 (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 XT run Ankh_base?▶
Yes. At Q4 it generates ~1216.2-1486.5 tok/s and fits up to 252k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~60.8-74.3 tok/s.
How much context fits?▶
At Q4, up to about 252k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
