// RUN โ€” FITS

Can the AMD Instinct MI300X 192GB run Pythia-1.4b?

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

Pythia-1.4b on the AMD Instinct MI300X 192GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 2630k 1192.5-1457.5 t/s ~9-11 (slow)
Q8 yes 2651k 2385-2915 t/s ~18-22 (slow)
Q4 yes 2660k 4258.9-5205.4 t/s ~32.1-39.3 (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 MI300X 192GB run Pythia-1.4b?โ–ถ

Yes. At Q4 it generates ~4258.9-5205.4 tok/s and fits up to 2660k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~32.1-39.3 tok/s.

How much context fits?โ–ถ

At Q4, up to about 2660k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
