Can the AMD Radeon RX 7900 XT run Gemma 3n?

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

Gemma 3n on the AMD Radeon RX 7900 XT

QuantFits?Max contextSpeedBeyond context
FP16 yes 9k 32.1-39.2 t/s ~1.6-2 (slow)
Q8 yes 69k 64.2-78.5 t/s ~3.2-3.9 (slow)
Q4 yes 95k 114.6-140.1 t/s ~5.7-7 (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 XT run Gemma 3n?โ–ถ

Yes. At Q4 it generates ~114.6-140.1 tok/s and fits up to 95k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~5.7-7 tok/s.

How much context fits?โ–ถ

At Q4, up to about 95k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
