Can the AMD Radeon RX 7800 XT run XLMR-XXL?โ–ถ

Yes. At Q4 it generates ~65.6-80.2 tok/s and fits up to 44k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~4.2-5.1 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.
