My experience is just the opposite, when I run even to projects on intelliJ on a mac m1 8gb, the whole system just starts lagging to the point that I cant even scroll the code.

This has not been a good experience for me.

That's probably because 8GB is not enough to run Intellij comfortably and the system starts swapping things in and out of memory constantly. Another thing that happens when intellij uses up its heap is garbage collects including frequent stop the world varieties of that. The solution is to configure it to have more heap. Either way, that's a memory problem and not a CPU problem.

8GB for a development laptop is not a great idea in 2021. I've been using 16GB since 2013. I'll get more with my next laptop, which may or may not end up being the 16" M2?

There was a bug with Android Studio (and I think IntelliJ as well) on M1, not sure if there still is.
