Can the AMD Instinct MI455X run Stable Beluga 1?

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

Stable Beluga 1 on the AMD Instinct MI455X

QuantFits?Max contextSpeedBeyond context
FP16 yes 810k 94.7-115.7 t/s ~0.2-0.2 (slow)
Q8 yes 1009k 189.4-231.5 t/s ~0.4-0.5 (slow)
Q4 yes 1097k 338.2-413.3 t/s ~0.7-0.8 (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 Stable Beluga 1?โ–ถ

Yes. At Q4 it generates ~338.2-413.3 tok/s and fits up to 1097k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.7-0.8 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1097k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
