// RUN โ€” FITS

Can the AMD Radeon Pro W7900 48GB run Pythia-160m?

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

Pythia-160m on the AMD Radeon Pro W7900 48GB

QuantFits?Max contextSpeedBeyond context
FP16 yes 646k 1701-2079 t/s ~78.8-96.3 (slow)
Q8 yes 648k 3402-4158 t/s ~157.5-192.5 (slow)
Q4 yes 650k 6075-7425 t/s ~281.3-343.8 (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 Radeon Pro W7900 48GB run Pythia-160m?โ–ถ

Yes. At Q4 it generates ~6075-7425 tok/s and fits up to 650k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~281.3-343.8 tok/s.

How much context fits?โ–ถ

At Q4, up to about 650k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
