Should I turn off my graphics card on my laptop, what is the benefit?

[Bruno Vincent]

I just bought a laptop with this graphics card:

Nvidia 920MX 2GB

I looked at the benchmarks for video card, and the stock integrated that comes with my i5-8250u chip is an Intel HD620 and it's just as powerful as the Nvidia....

Should I disable the Nvidia to save battery?

Is there a benefit from the Nvidia graphics card versus native intel HD or is it just a marketing gimmick from laptop manufacturers?

Seems like all graphic cards they have are the same as Intel HD620...!

The discrete nvidia adapter is much stronger than the intel integrated adapter. This is particularly important for fast action games.
But it also uses more power.
Your laptop balanced power profile will normally select the integrated adapter to save power when running on battery, and will use the nvidia adapter when plugged and gaming.

You can override this if you wish.

I won't game at all, ever, just office work, should I turn on graphic card for graphic design? Adobe illustrator and Photoshop?

Plugged in, use the nvidia adapter.
On battery, you will get longer run times with the integrated adapter.
