What hardware should I get to improve unity Frame rate?

Hi there!
I am thinking about buying some sort of hardware to upgrade my computer. However, I don’t know the first thing about computer hardware. I am using a laptop so I am not sure whether or not I can even add stuff to it.
I found these details about my computer in the Control Panel. I think it is a fairly average laptop:

I would like to increase the Frame rate of unity when I am using a lot of physics objects or making a procedural generation script. My current fps is fine now, I just want to be able to do more. Thanks in advance. : )

If your issue is with physics and procedural generation It means your issue is with the processor and you cant update that

OK. Thank you for letting me know
