Q8 yes 16k 30.4-37.2 t/s ~2.4-2.9 (slow)
Q4 yes 44k 54.3-66.4 t/s ~4.2-5.2 (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 Llama 3.2 11B?โ–ถ

Yes. At Q4 it generates ~54.3-66.4 tok/s and fits up to 44k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~4.2-5.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 44k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
