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

Gemma 4 E4B on the AMD Radeon RX 7900 XTX

QuantFits?Max contextSpeedBeyond context
FP16 yes 192k 75.6-92.4 t/s ~3.2-3.9 (slow)
Q8 yes 253k 151.2-184.8 t/s ~6.3-7.7 (slow)
Q4 yes 280k 270-330 t/s ~11.3-13.8 (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 7900 XTX run Gemma 4 E4B?โ–ถ

Yes. At Q4 it generates ~270-330 tok/s and fits up to 280k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~11.3-13.8 tok/s.

How much context fits?โ–ถ

At Q4, up to about 280k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
