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.

SilverBench · I felt like my laptop is gonna explode, i was genuinly afraid but its alright, but is it genuinly safe for my laptop to be 100% even if its just for the test? Cause the test took around 7 minutes, 7 straight minutes of my CPU at 100%, i got no complains tho.
