About the Score

This tool measures aggregate performance for floating-point arithmetic, integer arithmetic, and memory access using parallel processing (Web Workers) in the browser.

• Single Core: Performance using only one Worker. This indicator is close to the processing power of the JavaScript main thread.
• Multi Core: Parallel performance using all logical cores of the device. Shows the ability to handle heavy processing and multitasking.

Evaluation Ranks

Evaluates from Rank S to F based on the measured score.

• Rank S: Unrivaled speed. Latest high-end devices.
• Rank A: Very comfortable. Most apps run extremely smoothly.
• Rank B: Comfortable. Headroom to spare even when multitasking.
• Rank C: Standard. Sufficient performance for general web browsing.
• Rank D-F: Basic performance. Complex sites may experience slowdowns.

Browser Feature Support

Determines how well your browser supports the latest Web technologies (WebGPU, Passkeys, AV1 decoding, etc.). These are essential elements for enjoying a more advanced and faster Web experience.
