Why does the Chrome browser use so much more memory than other browsers?
Is there a good reason why Chrome seems to use more resources than other browsers on my PC? Actually, this is true running Chrome on Macs as well, so it isn’t just limited to Windows machines. What’s the payoff for using all of those system resources?
The main reason is that Chrome runs essentially everything as a separate process. So, each extension, each tab, etc. is another process. The benefit of this is that if something goes wrong in one tab, the entire browser doesn’t crash. The downside is, as you noticed, it can use more system resources.
