// RUN — FITS
Can the AMD Instinct MI325X run xLAM-8x22B?
Yes — here's how fast and up to what context, with real measured numbers.
xLAM-8x22B on the AMD Instinct MI325X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | no | — | — | — |
| Q8 | yes | 284k | 26.8-32.8 t/s | ~0.2-0.2 (slow) |
| Q4 | yes | 473k | 47.9-58.5 t/s | ~0.3-0.4 (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 MI325X run xLAM-8x22B?▶
Yes. At Q4 it generates ~47.9-58.5 tok/s and fits up to 473k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.3-0.4 tok/s.
How much context fits?▶
At Q4, up to about 473k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
