Can the AMD Instinct MI455X run PlasmidGPT?

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

FP16 yes 6038k 56127.3-68600 t/s ~114.5-140 (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 PlasmidGPT?โ–ถ

Yes. At Q4 it generates ~200454.5-245000 tok/s and fits up to 6041k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~409.1-500 tok/s.

How much context fits?โ–ถ

At Q4, up to about 6041k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
