FP16 yes 2891k 723.1-883.8 t/s ~1.5-1.8 (slow)
Q8 yes 2956k 1446.2-1767.6 t/s ~3-3.6 (slow)
Q4 yes 2984k 2582.5-3156.4 t/s ~5.3-6.4 (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 Instinct MI455X run Gemma 7B?โ–ถ

Yes. At Q4 it generates ~2582.5-3156.4 tok/s and fits up to 2984k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~5.3-6.4 tok/s.

How much context fits?โ–ถ

At Q4, up to about 2984k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
