Verified WebNN is compatible with following devices:

• Intel Core Ultra Desktop Processors

  • Meteor Lake (MTL)

• Intel Core Ultra Desktop Processors (Series 2)

  • Lunar Lake (LNL)
  • Arrow Lake (ARL)

How can I monitor hardware resources available to WebNN in the browser?

You can monitor system resources using several browser and system tools:

• For GPU information:

  • Access about://gpu to view detailed GPU diagnostics and error logs
  • Check about://histograms/webnn for WebNN-specific performance metrics

• For general system resources:

  • Browser resources: Open Google Chrome or Microsoft Edge Task Manager (Menu → More Tools → Task Manager) to monitor memory usage and CPU consumption
  • System resources: Use Windows Task Manager to monitor CPU, GPU, and NPU utilization
