CPU Stress Testing & Thermal Throttling Analysis
Modern multi-core processors boost clock speeds aggressively until hitting thermal or power limits. Our CPU Stress Test spawns dedicated Web Workers across all available hardware concurrency threads, running compute-heavy mathematical workloads to saturate CPU cores at 100% utilization. By monitoring operations-per-second graphs over 1, 5, or 15 minute cycles, you can spot thermal throttling caused by dried thermal paste or clogged laptop cooling fans.
3D Graphics Acceleration & WebGL Benchmarking
Evaluate your graphics card with our GPU Stress Test and GPU Info Checker. Built on lightweight Three.js scenes, the test renders complex 3D geometry, high-resolution textures, and dynamic lighting to measure sustained frames per second, frame time stability, and WebGL2 hardware feature limits. Discover whether your laptop is currently utilizing its high-performance dedicated Nvidia/AMD GPU or integrated graphics.
Musical Instrument Tuning & Timing Calibration
Harnessing advanced YIN autocorrelation pitch algorithms, LaptopXray includes professional Guitar and Ukulele Tuners that analyze microphone input to detect fundamental frequencies with sub-cent accuracy. The browser Metronome employs a Web Audio lookahead scheduler to deliver rock-solid, sample-accurate beats from 20 to 300 BPM with custom time signatures and tap-tempo functionality.
