// RUN — FITS
Can the AMD Instinct MI325X run IBM Granite 4.1?
Yes — here's how fast and up to what context, with real measured numbers.
IBM Granite 4.1 on the AMD Instinct MI325X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 664k | 63-77 t/s | ~0.4-0.5 (slow) |
| Q8 | yes | 778k | 126-154 t/s | ~0.8-1 (slow) |
| Q4 | yes | 829k | 225-275 t/s | ~1.5-1.8 (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 IBM Granite 4.1?▶
Yes. At Q4 it generates ~225-275 tok/s and fits up to 829k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~1.5-1.8 tok/s.
How much context fits?▶
At Q4, up to about 829k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
