Greetings,

so there are two kinds of graphics cards:

- Integrated

- Dedicated

The Intel UHD 620 is an integrated version which is not meant for gaming and such. For more graphic intensive tasks such as high level designing in CAD or Catia you'd probably require a dedicated graphics card.

Now, you cannot fix the graphics problem by upgrading to a laptop with core i5 in it, graphics cards (dedicated ones) are specifically mentioned and marketed while selling laptops. some basic ones include Nvidia GeForce MX150/MX250 and some gaming ones include GTX960, GTX1050, etc.

- as an ECE student, if you plan on delving into design or some AI related model testing then buy a laptop with a strong  GPU (graphics card), otherwise for normal tasks like making projects, watching videos, etc. your laptop is just fine.

good day!
