What I learned from stress testing LLM on NPU vs CPU on an Android phone
We ran a 10-minute LLM stress test on Samsung S25 Ultra CPU vs Qualcomm Hexagon NPU to see how the same model (LFM2-1.2B, 4 Bit quantization) performed. And I wanted to share some test results here for anyone interested in real on-device performance data.
https://youtu.be/Qvdtqq-0mqA
In 3 minutes, the CPU hit 42 °C and throttled: throughput fell from \~37 t/s → \~19 t/s.
The NPU stayed cooler (36–38 °C) and held a steady \~90 t/s—2–4× faster than CPU under load...
