Intel Atom processors are less powerful, but they can handle web browsing especially if you’re using a lightweight browser optimized for Intel Atom.

The standard browsers like Chrome, Mozilla, and Edge, are excellent and have a lot of features, but they aren’t the best choice for Intel Atom computers.

Which browser uses the least RAM and CPU?

As we all know, not all browsers are made the same. Differences range from the number of customization options to the browsing speed, site optimization, stability, privacy, and many others.

The most crucial difference between the browsers available on the market is the number of resources they require to run optimally. So naturally, a browser with low resource requirements is the best option, but a balance between stability is the best choice.

For the test to be correct, each of these browsers was tested on the same system, with the same OS, and with the same general circumstances:

  • no other apps running in the background
  • the same video playing at 720p quality was used

Here are the results we got:
