SmolLM-1.7B on the AMD Radeon RX 7900 XT

QuantFits?Max contextSpeedBeyond context
FP16 yes 206k 147.4-180.1 t/s ~7.4-9 (slow)
Q8 yes 232k 294.7-360.2 t/s ~14.7-18 (slow)
Q4 yes 243k 526.3-643.3 t/s ~26.3-32.2 (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 ~526.3-643.3 tok/s and fits up to 243k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~26.3-32.2 tok/s.

How much context fits?โ–ถ

At Q4, up to about 243k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
