Can the AMD Instinct MI455X run OpenThaiGPT 1.6 / OTG-1.6 (72B)?
Yes — here's how fast and up to what context, with real measured numbers.
OpenThaiGPT 1.6 / OTG-1.6 (72B) on the AMD Instinct MI455X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 769k | 85.8-104.8 t/s | ~0.2-0.2 (slow) |
| Q8 | yes | 989k | 171.5-209.6 t/s | ~0.4-0.4 (slow) |
| Q4 | yes | 1085k | 306.3-374.3 t/s | ~0.6-0.8 (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 MI455X run OpenThaiGPT 1.6 / OTG-1.6 (72B)?▶
Yes. At Q4 it generates ~306.3-374.3 tok/s and fits up to 1085k context; beyond that it spills to system RAM offload (depends on your system RAM) and slows to ~0.6-0.8 tok/s.
How much context fits?▶
At Q4, up to about 1085k tokens stay in fast memory; longer context spills to system RAM offload (depends on your system RAM) and throughput collapses.
