9bench

What 9bench measures

9bench is a free, open browser-based hardware benchmark that tests your CPU, GPU, and RAM speed in about 15 seconds — no download, no installation, no account required. The entire benchmark runs locally in your browser using WebGPU compute shaders, WebAssembly, Web Workers, and the Web Crypto API.

How it differs from UserBenchmark and Geekbench

r/pcmasterrace and r/hardware have banned UserBenchmark.com due to documented anti-AMD bias. Geekbench, Cinebench, 3DMark, and PassMark all require 500MB–8GB downloads and admin rights — unusable in corporate networks, schools, and on shared computers. 9bench fills the gap: instant, transparent, no install, fair scoring.

What gets tested

• GPU compute — 1024×1024 floating-point matrix multiplication via WebGPU compute shader. Output: GFLOPS.
• CPU single-core — 200,000 SHA-256 hashes computed serially. Output: hashes/sec + score.
• CPU multi-core — Same workload across all cores via Web Workers. Output: hashes/sec + speedup efficiency.
• RAM bandwidth — 256 MB working set tested for sequential read, write, copy, plus random-access latency.
