Can the AMD Radeon RX 7900 XTX 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 XTX

QuantFits?Max contextSpeedBeyond context
FP16 yes 37k 38.5-47.1 t/s ~1.6-2 (slow)
Q8 yes 97k 77-94.2 t/s ~3.2-3.9 (slow)
Q4 yes 123k 137.6-168.2 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 XTX run Gemma 3n?โ–ถ

Yes. At Q4 it generates ~137.6-168.2 tok/s and fits up to 123k 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 123k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
