Can the AMD Instinct MI300X 192GB run NASA SMD?
Yes — here's how fast and up to what context, with real measured numbers.
NASA SMD on the AMD Instinct MI300X 192GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2669k | 13356-16324 t/s | ~100.8-123.2 (slow) |
| Q8 | yes | 2671k | 26712-32648 t/s | ~201.6-246.4 (slow) |
| Q4 | yes | 2671k | 47700-58300 t/s | ~360-440 (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 NASA SMD?▶
Yes. At Q4 it generates ~47700-58300 tok/s and fits up to 2671k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~360-440 tok/s.
How much context fits?▶
At Q4, up to about 2671k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
