Can the AMD Instinct MI325X run P-Mistral?
Yes โ here's how fast and up to what context, with real measured numbers.
P-Mistral on the AMD Instinct MI325X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1679k | 270-330 t/s | ~1.8-2.2 (slow) |
| Q8 | yes | 1732k | 540-660 t/s | ~3.6-4.4 (slow) |
| Q4 | yes | 1756k | 964.3-1178.6 t/s | ~6.4-7.9 (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 P-Mistral?โถ
Yes. At Q4 it generates ~964.3-1178.6 tok/s and fits up to 1756k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~6.4-7.9 tok/s.
How much context fits?โถ
At Q4, up to about 1756k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
