Can the AMD Radeon RX 9070 XT run Qwen1.5-14B?โ–ถ

Yes. At Q4 it generates ~51.8-63.3 tok/s and fits up to 33k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~3.2-3.9 tok/s.

How much context fits?โ–ถ

At Q4, up to about 33k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
