Can the AMD Instinct MI455X run DeepSeek Coder 33B?

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

DeepSeek Coder 33B on the AMD Instinct MI455X

QuantFits?Max contextSpeedBeyond context
FP16 yes 1259k 187.1-228.7 t/s ~0.4-0.5 (slow)
Q8 yes 1385k 374.2-457.3 t/s ~0.8-0.9 (slow)
Q4 yes 1440k 668.2-816.7 t/s ~1.4-1.7 (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 DeepSeek Coder 33B?โ–ถ

Yes. At Q4 it generates ~668.2-816.7 tok/s and fits up to 1440k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~1.4-1.7 tok/s.

How much context fits?โ–ถ

At Q4, up to about 1440k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
