Can the AMD Instinct MI455X run Mamba2-Hybrid?
Yes — here's how fast and up to what context, with real measured numbers.
Mamba2-Hybrid on the AMD Instinct MI455X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2889k | 712.9-871.4 t/s | ~1.5-1.8 (slow) |
| Q8 | yes | 2955k | 1425.9-1742.7 t/s | ~2.9-3.6 (slow) |
| Q4 | yes | 2984k | 2546.2-3112 t/s | ~5.2-6.4 (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.
FAQ
Can the AMD Instinct MI455X run Mamba2-Hybrid?▶
Yes. At Q4 it generates ~2546.2-3112 tok/s and fits up to 2984k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~5.2-6.4 tok/s.
How much context fits?▶
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.
