Can the AMD Instinct MI300X 192GB 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 Instinct MI300X 192GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 2583k 570.8-697.6 t/s ~4.3-5.3 (slow)
Q8 yes 2628k 1141.5-1395.2 t/s ~8.6-10.5 (slow)
Q4 yes 2647k 2038.5-2491.5 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.

Can the AMD Instinct MI300X 192GB run Unified-IO (XL)?โ–ถ

Yes. At Q4 it generates ~2038.5-2491.5 tok/s and fits up to 2647k 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 2647k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
