Can the AMD Radeon RX 7800 XT run AntiFormer?
Yes — here's how fast and up to what context, with real measured numbers.
AntiFormer on the AMD Radeon RX 7800 XT
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 201k | 7967.4-9737.9 t/s | ~510.7-624.2 (slow) |
| Q8 | yes | 201k | 15934.8-19475.8 t/s | ~1021.5-1248.4 (slow) |
| Q4 | yes | 202k | 28454.9-34778.2 t/s | ~1824-2229.4 (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 AntiFormer?▶
Yes. At Q4 it generates ~28454.9-34778.2 tok/s and fits up to 202k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~1824-2229.4 tok/s.
How much context fits?▶
At Q4, up to about 202k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
