ApexMark › Web CPU benchmark
Web CPU benchmark
How fast is your processor when the work comes from a web page? ApexMark runs JavaScript ray tracing in workers, checks the finished image and measures cache behavior. Try the same device in different browsers to see the difference.
Run the benchmarkWhy a web CPU benchmark is different
Between a web page and your processor sit the JavaScript engine, JIT compiler, worker scheduling and operating system. This test measures that whole path, which matters to web apps and games. Its score is specific to ApexMark’s verified ray-tracing and cache workloads.
Compare Chrome, Edge, Firefox and Safari
The fastest browser is not fixed. Try two current browsers on the same device under similar conditions. For repeat runs, use the same browser and version, and compare scores only within the same ApexMark protocol.
Built for repeatable results
- Ray tracing runs in dedicated JavaScript workers, away from the main thread.
- Each protocol is versioned; a changed protocol gets its own scoreboard.
- Device, operating system, browser and protocol details are stored with every result.
Frequently asked questions
What is a web CPU benchmark?
A processor test run in a browser tab. ApexMark uses JavaScript workers to render a fixed image and run a separate cache lookup test; there is no native program to install.
Which browser gives the highest CPU score?
It varies by device, browser version and system conditions. Test two browsers on the same machine and keep the conditions as similar as possible.
Are results saved?
Runs can be kept in local browser history and exported as JSON. Account sync and Hall of Fame publishing are optional.
