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.

Can the AMD Radeon RX 7900 XTX run XLMR-XXL?โ–ถ

Yes. At Q4 it generates ~100.9-123.4 tok/s and fits up to 89k 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 89k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
