Can the Instinct MI430X run Phi-1.5?
Yes — here's how fast and up to what context, with real measured numbers.
Phi-1.5 on the Instinct MI430X
| Quant | Fits? | Max context | Speed | Beyond context |
|---|---|---|---|---|
| FP16 | yes | 6002k | 5645.8-6900.4 t/s | ~9.7-11.8 (slow) |
| Q8 | yes | 6022k | 11291.5-13800.8 t/s | ~19.4-23.7 (slow) |
| Q4 | yes | 6030k | 20163.5-24644.2 t/s | ~34.6-42.3 (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
