Can the AMD Instinct MI455X run Playground v2.5?

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

Playground v2.5 on the AMD Instinct MI455X

QuantFits?Max contextSpeedBeyond context
FP16 yes 5935k 1764-2156 t/s ~3.6-4.4 (slow)
Q8 yes 5988k 3528-4312 t/s ~7.2-8.8 (slow)
Q4 yes 6012k 6300-7700 t/s ~12.9-15.7 (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 Instinct MI455X run Playground v2.5?โ–ถ

Yes. At Q4 it generates ~6300-7700 tok/s and fits up to 6012k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~12.9-15.7 tok/s.

How much context fits?โ–ถ

At Q4, up to about 6012k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
