Can the AMD Radeon RX 7900 XT run ProtGPT2?

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

ProtGPT2 on the AMD Radeon RX 7900 XT

QuantFits?Max contextSpeedBeyond context
FP16 yes 235k 341.5-417.3 t/s ~17.1-20.9 (slow)
Q8 yes 247k 682.9-834.7 t/s ~34.1-41.7 (slow)
Q4 yes 252k 1219.5-1490.5 t/s ~61-74.5 (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 ProtGPT2?โ–ถ

Yes. At Q4 it generates ~1219.5-1490.5 tok/s and fits up to 252k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~61-74.5 tok/s.

How much context fits?โ–ถ

At Q4, up to about 252k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
