Can the AMD Instinct MI455X run CodeT5-large?

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

CodeT5-large on the AMD Instinct MI455X

FP16 yes 6018k 8018.2-9800 t/s ~16.4-20 (slow)
Q8 yes 6030k 16036.4-19600 t/s ~32.7-40 (slow)
Q4 yes 6035k 28636.4-35000 t/s ~58.4-71.4 (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 CodeT5-large?โ–ถ

Yes. At Q4 it generates ~28636.4-35000 tok/s and fits up to 6035k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~58.4-71.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 6035k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
