System Benchmark
A web-based benchmark for PCs and mobile devices โ no download needed. Test your device's CPU, memory, GPU, and disk performance right in the browser. Scores are normalized to a 60-second window.
๐งฉ CPU and Memory benchmarks run as compiled WebAssembly for closer-to-hardware results, though scores may still vary slightly between browsers due to differences in WASM compiler quality. Keep this tab in focus during benchmarks โ background tabs may be throttled by your browser.
