Can the AMD Radeon RX 7900 XT run OLMo-1B?

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

OLMo-1B on the AMD Radeon RX 7900 XT

QuantFits?Max contextSpeedBeyond context
FP16 yes 227k 252-308 t/s ~12.6-15.4 (slow)
Q8 yes 243k 504-616 t/s ~25.2-30.8 (slow)
Q4 yes 249k 900-1100 t/s ~45-55 (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 RX 7900 XT run OLMo-1B?โ–ถ

Yes. At Q4 it generates ~900-1100 tok/s and fits up to 249k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~45-55 tok/s.

How much context fits?โ–ถ

At Q4, up to about 249k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
