Q4 yes 67k 72-88 t/s ~5.6-6.9 (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 LFM2.5-8B-A1B?โ–ถ

Yes. At Q4 it generates ~72-88 tok/s and fits up to 67k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~5.6-6.9 tok/s.

How much context fits?โ–ถ

At Q4, up to about 67k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
