Can the AMD Radeon RX 6800 XT run Mamba2-Hybrid?

Yes โ€” here's how fast and up to what context, with real measured numbers.

Q8 yes 35k 37.2-45.5 t/s ~2.9-3.6 (slow)
Q4 yes 64k 66.5-81.3 t/s ~5.2-6.4 (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 6800 XT run Mamba2-Hybrid?โ–ถ

Yes. At Q4 it generates ~66.5-81.3 tok/s and fits up to 64k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~5.2-6.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 64k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
