I don't use chrome, but I've heard it uses around 250MB per tab.The comments here are probably a good indication of who bought 8GB vs. 16GB RAM on their M1. ?
I've always had a lot of tabs open and since Safari added tab groups I've gone even further - I have hundreds of tabs now and Safari is only using 3.4GB. About what Chrome would allegedly use with just 14 tabs.
I'd probably need a Mac Pro with 512GB of RAM to switch to Chrome - or I'd need to change how I browse (switch to using bookmarks instead of tabs maybe? That sounds like a pain in the ass).
