- Visual Look Up (VLU) on Apple silicon Macs involves significant CPU and neural engine (ANE) activity.
- Power measurements were taken using powermetrics on a Mac mini M4 Pro running macOS 15.6.1.
- The ANE was active from 1.4-2.2 seconds, with initial object detection followed by nature world identification.
- Total power use during VLU was 93% CPU, 4.6% GPU, and 2.2% ANE.
- Energy used over 6.5 seconds: CPU 6.4 J, GPU 0.3 J, ANE 0.2 J, totaling 6.9 J.
- Peak power usage occurred between 1.0-2.5 seconds, correlating with log events.
- VLU is not highly demanding on hardware, with most work done by the CPU.
