In two different tests performed with certain applications and multiple tabs open, the Chrome browser is almost consumed with everything. Safari, on the other hand, remains at very low levels.
While energy efficiency is increasingly becoming prominent in computer systems, we see that some services still have difficulty in providing this. Although Google Chrome has made great progress so far, it is still not at the desired level.
There is a problem with the macOS Chrome platform
The Google Chrome browser is constantly being developed, but there is an excessive use of resources on the macOS platform side that cannot compete with Safari. From time to time, this difference is up to 20 times.
Tests conducted by Flotato developer Morten Just with Safari and Chrome browsers have clearly revealed this difference. Flotato is known for emulating mobile applications on macOS.
The developer opened the Gmail and Twitter applications and tested the browsers. Memory and processor usage were also recorded 250 times a second with the Psrecord application. As a result, while Safari browser uses 73MB of RAM, Chrome has reached up to 730MB. A minute later, Chrome passed the 1GB limit, but Safari remained at 80MB.
Later, the developer did a multi-tab test on his own version of macOS. While 54 tabs were open in each browser, Chrome used 290MB of RAM per tab. Safari is around 12MB per tab.
As you can see, the differences are vast and the RAM consumption of the Chrome browser has been a complaint for a long time. Chrome is trying to offer many innovations to macOS users, including Apple M1 compatibility, but RAM consumption is still not resolved.
