Can the AMD Instinct MI300X 192GB 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 MI300X 192GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2665k | 6496.1-7939.7 t/s | ~49-59.9 (slow) |
| Q8 | yes | 2669k | 12992.2-15879.4 t/s | ~98.1-119.8 (slow) |
| Q4 | yes | 2670k | 23200.4-28356 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 MI300X 192GB run Segatron XL base, M=384?▶
Yes. At Q4 it generates ~23200.4-28356 tok/s and fits up to 2670k 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 2670k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
