Can the AMD Radeon RX 6900 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 6900 XT

QuantFits?Max contextSpeedBeyond context
FP16 yes 186k 322.6-394.2 t/s ~25.2-30.8 (slow)
Q8 yes 194k 645.1-788.5 t/s ~50.4-61.6 (slow)
Q4 yes 197k 1152-1408 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 6900 XT run Spec-Drafter?โ–ถ

Yes. At Q4 it generates ~1152-1408 tok/s and fits up to 197k 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 197k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
