When it comes to how much RAM a browser should use, you should know that there is no specific amount of RAM that a browser should use, as the answer depends on how you use the PC.

This splits situations like this into three separate groups:

Type of user	Usage	RAM requirement
Casual user	simple internet browsing, email exchange, watching videos, listening to music, etc.	you can perform these browser tasks without any problems if your system has at least 1-2 GB of RAM
Intermediate user	browsing, word processing, spreadsheets, multitasking, running simple graphic programs, etc.	you will be able to seamlessly complete your actions if your system has between 2 and 4 GB of RAM.
Professional user	high-performance online gaming, graphic design/3D modeling, intensive multitasking, ultra-high-definition videos, multimedia editing, etc.	anything less than 8GB will severely impact the way you can achieve your online goals, and the processes will also lag considerably. In order to be fully ready for this type of task, 16GB or 32GB RAM is recommended

First, analyzing the above information will ensure that you estimate the amount of RAM you should aim for depending on your device usage.

Let’s move on and find out what browser offers the perfect balance between system requirements and speed, agility, stability, and security.
