Can the AMD Radeon RX 7900 XT run Spec-Drafter?

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

Spec-Drafter on the AMD Radeon RX 7900 XT

QuantFits?Max contextSpeedBeyond context
FP16 yes 243k 504-616 t/s ~25.2-30.8 (slow)
Q8 yes 250k 1008-1232 t/s ~50.4-61.6 (slow)
Q4 yes 254k 1800-2200 t/s ~90-110 (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 Spec-Drafter?โ–ถ

Yes. At Q4 it generates ~1800-2200 tok/s and fits up to 254k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~90-110 tok/s.

How much context fits?โ–ถ

At Q4, up to about 254k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
