What are the minimum laptop settings for an average Photoshop?

Question

laptops

I plan to use photoshop without fanaticism - only a small retouch using filters but WITHOUT using 3D and animations and the like. And most likely I will put not the fattest and fancy version.
According to the RAM, I understand that you need from 4GB or more. There are two questions:
1. The minimum characteristics of the processor
2. Is it necessary to have a discrete video card

Answer 1

You need something like this laptop.
