Can the AMD Radeon RX 7900 XTX run Nanbeige2-16B-Chat?โ–ถ

Yes. At Q4 it generates ~68.4-83.5 tok/s and fits up to 45k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~2.8-3.5 tok/s.

How much context fits?โ–ถ

At Q4, up to about 45k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
