Heat and performance analysis of CPU vs QC NPU: https://x.com/nexa_ai/status/1987927448860995792 We ran a 10-minute LLM test on Samsung S25 Ultra CPU vs @Qualcomm Hexagon NPU. 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. Same 10-min, both used 6% battery, but productivity wasn’t equal: NPU: ~54k tokens ? ~9,000 tokens per 1% battery CPU: ~14.7k tokens ? ~2,443 tokens per 1% battery That’s ~3.7× more work per battery on the NPU—without throttling.
