Geekbench Has a Free API — Benchmark Any CPU Without Running Tests Yourself

The Story I was comparing ARM vs x86 cloud instances for a data pipeline. Running benchmarks myself would take hours across 12 different instance types. Then I discovered: Geekbench has a free, undocumented API that gives you benchmark scores for virtually any CPU ever tested. The API Geekbench's browser at browser.geekbench.com is powered by a JSON API: # Search for a specific CPU curl -s "https://browser.geekbench.com/search?q=Apple+M4" \ -H "Accept: application/json" # Get top single-core scores curl -s "https://browser.geekbench.com/v6/cpu/singlecore" \ -H "Accept: application/json" # Get top multi-core scores curl -s "https://browser.geekbench.com/v6/cpu/multicore" \ -H "Accept: application/json" What You Get For every benchmark result: Single-core score — raw per-thread performance Multi-core score — parallel workload performance System info — CPU model, cores, frequency, RAM Platform — macOS, Linux, Windows, Android, iOS Upload date — filter for recent results Practical Example:
