Can the AMD Instinct MI455X run Qwen1.5-110B?

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

Qwen1.5-110B on the AMD Instinct MI455X

QuantFits?Max contextSpeedBeyond context
FP16 yes 537k 56.1-68.6 t/s ~0.1-0.1 (slow)
Q8 yes 873k 112.3-137.2 t/s ~0.2-0.3 (slow)
Q4 yes 1020k 200.5-245 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 Qwen1.5-110B?โ–ถ

Yes. At Q4 it generates ~200.5-245 tok/s and fits up to 1020k 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 1020k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
