Can the AMD Instinct MI325X run Segatron XL base, M=384?
Yes — here's how fast and up to what context, with real measured numbers.
Segatron XL base, M=384 on the AMD Instinct MI325X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 3563k | 7354.1-8988.3 t/s | ~49-59.9 (slow) |
| Q8 | yes | 3567k | 14708.2-17976.7 t/s | ~98.1-119.8 (slow) |
| Q4 | yes | 3569k | 26264.6-32101.2 t/s | ~175.1-214 (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 Segatron XL base, M=384?▶
Yes. At Q4 it generates ~26264.6-32101.2 tok/s and fits up to 3569k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~175.1-214 tok/s.
How much context fits?▶
At Q4, up to about 3569k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
