However, if you're editing large 4K videos or doing other extremely intensive tasks, you might benefit from additional unified memory in your system. Reviews of the first M1 systems (the MacBook Pro and Mac Mini) show that Apple has finally been able to create a system with a base of 8GB of RAM that not only performs well but outperforms previous systems with twice as much RAM (also, it's called 'unified memory' now). Everything just works together and borrows processing from each other as needed. The CPU and GPU aren't both trying to access data pathways on the logic board. There's no memory swapping or rewriting of data between your RAM and SSD. The M1 chip can dynamically use whatever it needs, from whichever component it needs, instantaneously. Having everything on a single chip changes that fundamentally. RAM is a system's short term memory and having lots of it means you can do more and larger tasks simultaneously without slowing things down. Traditional thinking has always said, add as much RAM as you can afford.

But the more I researched the new M1 chip and how it's performed in the new MacBook Pro and Mac Mini, the less concerned I was. As someone who falls into that category, I expected to be more upset at the change.
