In a recent test, Chrome uses 10 times more Safari memory than Safari on macOS Big Sur



According to Flotato creator Morten Just (via iMore).

Google Chrome macOS

Just outlined in a blog post that he tested two browsers in both cases in the latest version of macOS. The first test was conducted on a virtual machine, and the second test was conducted on a 2019 16-inch MacBook Pro with 32GB RAM. In the first round of testing, Just simulated a typical browsing mode, that is, open Twitter, scroll through, and then use Gmail to open new tabs and write emails.

In this test, Just found that Chrome reached 1GB of RAM usage, while Safari only used 80MB of RAM. However, the two-tab test is only the beginning.

Among the 54 tabs just opened, Just found that the RAM used by each tab in Google Chrome is 24 times that of Safari. According to Just, neither browser has any extensions, and this particular test was performed on his actual MacBook Pro, not a virtual machine. According to his findings, Chrome uses 290MB of memory for each open tab, while Safari uses only 12MB of memory for each open tab.

Although the results are obvious, Just did say that Google Chrome may “do its best to manage memory usage between tabs” to maintain the “fast responsiveness” of the current tab. In the test, Just found that his application Flotato is a lightweight alternative to Chrome. It can create applications based on web pages, while using significantly less RAM than Safari and Chrome.

As we all know, Chrome is a memory occupant on Mac and Windows computers, and this is a problem that Google is trying to solve recently.

With the help of “macOS Big Sur”, Safari received an important update, making it far surpassing Chrome. Apple stated that the Safari browser on “macOS Big Sur” “loads frequently visited websites on average 50% faster than Chrome browser”, and the streaming video playback time provided by Safari can be extended by up to one and a half hours. And the normal web browsing time on Safari can be extended by up to an hour compared with Chrome and Firefox, only a single charge.
