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

LUXIA-21.4B-Alignment on the AMD Instinct MI300X 192GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 505k 78-95.4 t/s ~0.6-0.7 (slow)
Q8 yes 586k 156-190.7 t/s ~1.2-1.4 (slow)
Q4 yes 622k 278.6-340.5 t/s ~2.1-2.6 (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.

Yes. At Q4 it generates ~278.6-340.5 tok/s and fits up to 622k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~2.1-2.6 tok/s.

How much context fits?โ–ถ

At Q4, up to about 622k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
