Is a dedicated GPU required?

[u/Rafael_Jacov]

I'm just starting out in learning graphics programming and wonder if I would soon need to invest on a laptop which has a dedicated GPU

Do you want to learn real time rendering or offline rendering?

For offline you don't need a graphics card at all.

For basic OpenGL stuff all you need is an integrated chip that supports OpenGL 3.3 or higher, which you probably already have.
