Can the AMD Radeon RX 6900 XT run Gemma 2B?

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

Gemma 2B on the AMD Radeon RX 6900 XT

QuantFits?Max contextSpeedBeyond context
FP16 yes 125k 64.3-78.6 t/s ~5-6.1 (slow)
Q8 yes 163k 128.7-157.3 t/s ~10.1-12.3 (slow)
Q4 yes 180k 229.8-280.9 t/s ~18-21.9 (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 6900 XT run Gemma 2B?โ–ถ

Yes. At Q4 it generates ~229.8-280.9 tok/s and fits up to 180k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~18-21.9 tok/s.

How much context fits?โ–ถ

At Q4, up to about 180k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
