Only the device family, the browser and OS type, the range number of each value and the date are sent. Results are stored only as anonymous counts and are not linked to IP addresses or user agents. Your last 12 results stay on this device only.
Reading the three values
CPU single-core is the speed of one task, and CPU all-core is the speed of several tasks running at the same time, both shown as points for how much of a fixed calculation was done. Drawing is how many frames of shapes per second can be drawn on a Canvas. Higher is faster for all three.
The drawing value does not depend on the screen refresh rate (60 Hz or 120 Hz), so it is separate from how smooth the screen looks.
Frequently asked questions
Why does the value change every time I test?
The speed a CPU can reach changes with the device temperature, power-saving settings, and apps or tabs running in the background. Test a few times and look at the trend in your last 12 results.
What is a "device family"?
A family groups devices with the same performance. Android devices are grouped by model number, iPhones and iPads by screen resolution, and PCs by GPU name. Browsers cannot read the iPhone model, so iPhones with the same resolution share a family.
Where are my results sent?
The device family, the browser and OS type, the range number of each value and the date are sent once. Results are stored only as anonymous counts and are not linked to IP addresses or user agents. The list shows only families that have reached a minimum number of results, as the median and P25–P75.
