// RUN โ€” FITS

Can the AMD Instinct MI455X run BLOOM-176B?

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

BLOOM-176B on the AMD Instinct MI455X

QuantFits?Max contextSpeedBeyond context
FP16 yes 83k 35-42.8 t/s ~0.1-0.1 (slow)
Q8 yes 419k 70.1-85.6 t/s ~0.1-0.2 (slow)
Q4 yes 567k 125.1-152.9 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 BLOOM-176B?โ–ถ

Yes. At Q4 it generates ~125.1-152.9 tok/s and fits up to 567k 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 567k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
