Can the AMD Radeon RX 9070 XT run SANA 1.5 4.8B?

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

SANA 1.5 4.8B on the AMD Radeon RX 9070 XT

QuantFits?Max contextSpeedBeyond context
FP16 yes 55k 42.3-51.7 t/s ~2.6-3.2 (slow)
Q8 yes 128k 84.5-103.3 t/s ~5.3-6.4 (slow)
Q4 yes 161k 150.9-184.5 t/s ~9.4-11.5 (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.

Can the AMD Radeon RX 9070 XT run SANA 1.5 4.8B?โ–ถ

Yes. At Q4 it generates ~150.9-184.5 tok/s and fits up to 161k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~9.4-11.5 tok/s.

How much context fits?โ–ถ

At Q4, up to about 161k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
