Can the AMD Radeon RX 7800 XT 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 7800 XT

QuantFits?Max contextSpeedBeyond context
FP16 yes 22k 38.2-46.6 t/s ~2.4-3 (slow)
Q8 yes 62k 76.3-93.3 t/s ~4.9-6 (slow)
Q4 yes 79k 136.3-166.6 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 7800 XT run Qwen-VLA?โ–ถ

Yes. At Q4 it generates ~136.3-166.6 tok/s and fits up to 79k 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 79k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
