Can the AMD Instinct MI455X run Falcon-180B?

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

Falcon-180B on the AMD Instinct MI455X

QuantFits?Max contextSpeedBeyond context
FP16 yes 69k 34.3-41.9 t/s ~0.1-0.1 (slow)
Q8 yes 412k 68.6-83.8 t/s ~0.1-0.2 (slow)
Q4 yes 563k 122.5-149.7 t/s ~0.3-0.3 (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 Falcon-180B?โ–ถ

Yes. At Q4 it generates ~122.5-149.7 tok/s and fits up to 563k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.3-0.3 tok/s.

How much context fits?โ–ถ

At Q4, up to about 563k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
