Can the AMD Radeon RX 7900 XT run GPT-Neo-125M?

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

GPT-Neo-125M on the AMD Radeon RX 7900 XT

QuantFits?Max contextSpeedBeyond context
FP16 yes 254k 2016-2464 t/s ~100.8-123.2 (slow)
Q8 yes 256k 4032-4928 t/s ~201.6-246.4 (slow)
Q4 yes 257k 7200-8800 t/s ~360-440 (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 GPT-Neo-125M?โ–ถ

Yes. At Q4 it generates ~7200-8800 tok/s and fits up to 257k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~360-440 tok/s.

How much context fits?โ–ถ

At Q4, up to about 257k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
