With DDR5 RAM prices skyrocketing, some mid-range laptops could soon ship with budget-level specs. TrendForce expects companies like Dell and Lenovo to stock more notebooks with 8GB of memory. These reasonably priced options may no longer handle intense office and gaming tasks.
Depends on the the type office work.
If you use excel heavily with large datasets or say data vizualization software like PowerBI and Tableau, 8GB is definitely not going to be enough.
That being said, my grandma has an a 6GB RAM Windows 10 machine and it works fine for her relatively resource-lite use cases.
