Can the AMD Instinct MI325X run WizardLM 13B v1.2?
Yes — here's how fast and up to what context, with real measured numbers.
WizardLM 13B v1.2 on the AMD Instinct MI325X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 1270k | 145.4-177.7 t/s | ~1-1.2 (slow) |
| Q8 | yes | 1349k | 290.8-355.4 t/s | ~1.9-2.4 (slow) |
| Q4 | yes | 1384k | 519.2-634.6 t/s | ~3.5-4.2 (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.
