Description
A laptop with 4 GB DDR3 RAM is an older-generation system suitable mainly for basic tasks like web browsing, office work and light media use. DDR3 memory runs at higher voltage (1.5 V or 1.35 V for DDR3L), offers lower bandwidth than newer DDR4/DDR5, and is not compatible with newer RAM types. While stable and adequate for simple usage, 4 GB is quite limited for multitasking, modern apps, or heavy workloads, and such laptops often have reduced power efficiency and slower overall performance due to the older memory technology.
