at Blog post, Just clarified that it put both browsers to the test in two scenarios on the latest version of macOS. The first test was conducted on a virtual machine, the second on the 16-inch 2019 MacBook Pro with 32 GB of RAM. In the first round of testing, you just simulate a typical browsing pattern to open Twitter, scroll, then open a new tab with Gmail and create an email.
As part of this test, I just found out that Chrome reached 1GB of RAM usage, while Safari only used 80MB of RAM. However, the two-table test was only the beginning.
With 54 tabs open, I just found that Google Chrome uses 24 times more RAM per tab compared to Safari. Both browsers, according to Just, were devoid of any accessories, and this particular test was done on the actual MacBook Pro, not a virtual machine. According to his findings, Chrome used 290 MB of RAM per open tab, while Safari only used 12 MB of RAM per open tab.
Although the results are stark, Google Chrome has likely “gone out of its way to manage memory usage across tabs” in an effort to keep the current tab “fast and responsive.” In his tests, Just found that his app, Flotato, which is a lightweight alternative to Chrome that builds apps based on web pages, uses much less RAM than both Safari and Chrome.
Chrome has been known to be a memory-consuming thing on Mac and Windows computers, which is a problem that Google faced recently I tried to solve it.
With macOS Big Sur, Safari received important updates that made it superior to Chrome. Apple says Safari on macOS Big Sur is “50% faster on average at loading frequently visited websites than Chrome,” and that Safari delivers up to an hour and a half of video streaming and up to an hour of web browsing. Regular on one charge compared to Chrome and Firefox browsers.
