What this measures
Moves 24 DOM bars with transforms for a short window and counts frames. That is main-thread animation, not the WebGL cube rate.
How to read it
These figures describe the browser that loaded the page. A feature marked no means the matching tool cannot run. It does not mean the computer lacks the part.
What it cannot do
The user agent and the renderer string are hints, sometimes reduced. They are not a parts list. Timing for this page load is not a lab trace of every site you open.
Questions
Is the user agent a full inventory?
No. It is a string the browser chooses to send. Treat every row as browser-reported.
Why is the processor count low?
hardwareConcurrency can be capped. It is not a core diagram.
Can I export this?
Yes. The snapshot export downloads JSON to your machine. It is not uploaded.
