If I buy an 8GB RAM laptop and I expanded it to 16GB, does it work the same as an inbuilt 16GB laptop?

Expanding an 8GB RAM laptop to 16GB will improve its performance, but it won’t work exactly the same as an inbuilt 16GB laptop. In general, a laptop with more RAM will perform better when running multiple applications or using memory-intensive programs. However, laptops with inbuilt 16GB RAM often come with other improvements, such as better processors or graphics cards, which may offer better overall performance. For example, the HP Pavilion Aero 13-be2056AU is a great laptop that comes with inbuilt 16GB DDR5 6400 MHz RAM and comes with a Ryzen 5 7535U CPU for comparatively better performance.
