Can the AMD Radeon RX 6800 XT run ProtGPT2?

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

ProtGPT2 on the AMD Radeon RX 6800 XT

QuantFits?Max contextSpeedBeyond context
FP16 yes 179k 218.5-267.1 t/s ~17.1-20.9 (slow)
Q8 yes 190k 437.1-534.2 t/s ~34.1-41.7 (slow)
Q4 yes 195k 780.5-953.9 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 6800 XT run ProtGPT2?โ–ถ

Yes. At Q4 it generates ~780.5-953.9 tok/s and fits up to 195k 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 195k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
