Opera One vs Chrome CPU usage

We ran a CPU usage test between Opera One and Google Chrome. The test was simple, we opened one website, i.e., Facebook.com, and after completely loading the webpage, opened the Windows Task Manager to check which browser ate up more CPU and RAM.

In the Task Manager, it was clearly evident that Google Chrome’s CPU usage was way higher compared to the browser’s usage. Google Chrome’s CPU usage was 19%, whereas the Opera One browser only used 0.2% of the CPU.

The memory used by Chrome was around 548.8 MB, compared to 270.3 MB by the Opera One browser. So, by a huge margin, Opera One is the better browser than Chrome, when we talk about CPU usage.
