Can the AMD Instinct MI325X run GPT-Neo-1.3B?

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

GPT-Neo-1.3B on the AMD Instinct MI325X

QuantFits?Max contextSpeedBeyond context
FP16 yes 3531k 1453.8-1776.9 t/s ~9.7-11.8 (slow)
Q8 yes 3551k 2907.7-3553.8 t/s ~19.4-23.7 (slow)
Q4 yes 3560k 5192.3-6346.2 t/s ~34.6-42.3 (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 MI325X run GPT-Neo-1.3B?โ–ถ

Yes. At Q4 it generates ~5192.3-6346.2 tok/s and fits up to 3560k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~34.6-42.3 tok/s.

How much context fits?โ–ถ

At Q4, up to about 3560k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
