FP16 yes 201k 8222.7-10050 t/s ~510.7-624.2 (slow)
Q8 yes 201k 16445.5-20100 t/s ~1021.5-1248.4 (slow)
Q4 yes 202k 29366.9-35892.9 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 9070 XT run AntiFormer?โ–ถ

Yes. At Q4 it generates ~29366.9-35892.9 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?โ–ถ

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.
