Can the AMD Instinct MI455X run BLOOM-3B?

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

BLOOM-3B on the AMD Instinct MI455X

QuantFits?Max contextSpeedBeyond context
FP16 yes 5950k 2058-2515.3 t/s ~4.2-5.1 (slow)
Q8 yes 5996k 4116-5030.7 t/s ~8.4-10.3 (slow)
Q4 yes 6016k 7350-8983.3 t/s ~15-18.3 (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-3B?โ–ถ

Yes. At Q4 it generates ~7350-8983.3 tok/s and fits up to 6016k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~15-18.3 tok/s.

How much context fits?โ–ถ

At Q4, up to about 6016k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
