Can the AMD Instinct MI300X 192GB run Qwen2.5-1.5B?
Yes — here's how fast and up to what context, with real measured numbers.
Qwen2.5-1.5B on the AMD Instinct MI300X 192GB
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 2625k | 1084.1-1325 t/s | ~8.2-10 (slow) |
| Q8 | yes | 2649k | 2168.2-2650 t/s | ~16.4-20 (slow) |
| Q4 | yes | 2659k | 3871.8-4732.1 t/s | ~29.2-35.7 (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.
