SilverBench · CPU Benchmark & Stress Test Online

No Chromium browser!? Firefox & Edge is slow · Learn how to be fast…

SilverBench · fast and easy multicore CPU benchmark that runs directly in your browser using JavaScript. Powered by a photon-mapping rendering engine, it measures raw CPU performance on PC or mobile. Choose from three modes—Performance, Extreme, or Stress. All tests run on the CPU only (no GPU required). The stress test is ideal for burn-in, heat, and stability checks.

Check out the recent changes we've made—and those still on the way—to keep SilverBench future-proof for online CPU, GPU, and WEB benchmarking.
