Can the AMD Radeon RX 7900 XTX run Qwen-VLA?

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

Qwen-VLA on the AMD Radeon RX 7900 XTX

QuantFits?Max contextSpeedBeyond context
FP16 yes 78k 58.7-71.8 t/s ~2.4-3 (slow)
Q8 yes 118k 117.4-143.5 t/s ~4.9-6 (slow)
Q4 yes 135k 209.7-256.3 t/s ~8.7-10.7 (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 XTX run Qwen-VLA?โ–ถ

Yes. At Q4 it generates ~209.7-256.3 tok/s and fits up to 135k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~8.7-10.7 tok/s.

How much context fits?โ–ถ

At Q4, up to about 135k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
