There is a huge difference between my laptop and my desktop in using VS Code with a few basic plugins. The difference of the hardware between the 2 machines is mostly CPU and SSD performance, the SSD makes a big impact opening projects with many small files, but the CPU is used for IntelliSense or even when you copy/paste a few thousands of LOC from one file to another (laptop fan gets to max for tens of seconds).

This is the biggest difference I see today. In the previous generation it was a huge boost in everything just becauase the old CPU was really old. I also keep CPUs 5 years or more.
