Do you need a discrete graphics card in an old macbook?

Question

macbook

Good afternoon!
I'm going to buy a macbook pro 15 2015.
Should I consider options with a discrete graphics card?
What is the use of it in 2020?
The laptop will be used for learning ios development.

Answer 1

if you do not mount the video, in general, you do not need it. There are still extremes on the connected monitors, but in general it's all the same.
ps My main laptop now is macbook 15 "2013 late with gt750. I wanted to change it to 16" six months ago, but it didn't grow together. Now I see how the market is changing.

Answer 2

Enough, even I would say it’s good that it won’t be (the laptop is old, so that there are no problems with the video card, the discrete may fall off). All you need for programming.
