RAM is one of the major components that one needs to consider when getting a laptop for 3D rendering. It might seem as if you need a lot, but 8GB RAM can do the job just right. You can run various software and multitask without having to worry about system failure.
But if you are planning on running high-end software and wish for a fully optimized experience then we suggest that you opt for 32 GB RAM. As we say, the higher the better!
