In the first round of testing, Just simulated a typical browsing pattern of opening Twitter, scrolling around, and then opening a new tab with Gmail and composing an email.
The first test was conducted on a virtual machine, and the second on a 2019 16-inch MacBook Pro with 32GB of RAM. In a blog post, Just outlines that he put both browsers to the test in two scenarios on the latest version of macOS.
Under normal and lightweight web browsing, Google Chrome uses 10x more RAM than Safari on macOS Big Sur, according to a test conducted by Flotato creator Morten Just (via iMore).
