Can the AMD Instinct MI455X run GLM-4.5-Air?

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

GLM-4.5-Air on the AMD Instinct MI455X

QuantFits?Max contextSpeedBeyond context
FP16 yes 561k 58.2-71.2 t/s ~0.1-0.1 (slow)
Q8 yes 885k 116.5-142.4 t/s ~0.2-0.3 (slow)
Q4 yes 1027k 208-254.2 t/s ~0.4-0.5 (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 Instinct MI455X run GLM-4.5-Air?โ–ถ

Yes. At Q4 it generates ~208-254.2 tok/s and fits up to 1027k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.4-0.5 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1027k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
