System & Hardware — Tests & Tools

Stress test your CPU in the browser. One Web Worker per core loads the processor to 100% — watch live operations per second and per-thread activity, and get a score you can compare between devices.

Stress test your graphics card with WebGL. Render up to 10,000 rotating 3D cubes with heavy shaders, watch the live frame rate, and get a benchmark score with average, minimum, and 1% low FPS.

Test your RAM speed in the browser. Four passes — sequential write, sequential read, random access, and memory copy — measure how fast your machine moves data, with a GB/s score you can compare between devices.

Convert RAM speed and CAS latency into true latency in nanoseconds — compare DDR4 and DDR5 kits fairly, see bandwidth and cycle time, and check whether a memory upgrade is actually faster.
