Can the AMD Instinct MI455X run BART-IT?

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

BART-IT on the AMD Instinct MI455X

QuantFits?Max contextSpeedBeyond context
FP16 yes 6037k 44100-53900 t/s ~90-110 (slow)
Q8 yes 6039k 88200-107800 t/s ~180-220 (slow)
Q4 yes 6040k 157500-192500 t/s ~321.4-392.9 (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 BART-IT?โ–ถ

Yes. At Q4 it generates ~157500-192500 tok/s and fits up to 6040k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~321.4-392.9 tok/s.

How much context fits?โ–ถ

At Q4, up to about 6040k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
