Can the AMD Radeon RX 7900 XT run Unified-IO (XL)?

Yes โ€” here's how fast and up to what context, with real measured numbers.

Unified-IO (XL) on the AMD Radeon RX 7900 XT

QuantFits?Max contextSpeedBeyond context
FP16 yes 169k 86.2-105.3 t/s ~4.3-5.3 (slow)
Q8 yes 213k 172.3-210.6 t/s ~8.6-10.5 (slow)
Q4 yes 233k 307.7-376.1 t/s ~15.4-18.8 (slow)

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.

FAQ

Can the AMD Radeon RX 7900 XT run Unified-IO (XL)?โ–ถ

Yes. At Q4 it generates ~307.7-376.1 tok/s and fits up to 233k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~15.4-18.8 tok/s.

How much context fits?โ–ถ

At Q4, up to about 233k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
