Tired of one-tab browser tests? Traditional benchmarks are outdated. SpeedPower.run is the first zero-install tool that stress-tests your device's Maximum Concurrent Compute by saturating all CPU and GPU cores simultaneously. It runs seven parallel, weighted benchmarks: JavaScript, Web Worker Exchange, and five distinct AI inference models (2 from TensorFlow.js and 3 from Transformers). See if your rig is ready for the AI-driven web.
