Can the AMD Radeon RX 6800 XT run CausalLM 14B?โ–ถ

Yes. At Q4 it generates ~39.2-47.9 tok/s and fits up to 30k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~3.1-3.7 tok/s.

How much context fits?โ–ถ

At Q4, up to about 30k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
