Processor upgrade chipset and cores

In the next few months, I will be buying this computer to go to college for biomedical engineering. I am trying to decide on the specs I should go for and which don't matter. I looked at the teardown which showed the standard dual core i5. My question is do y'all know what the chipset of the i7 upgrade from the Apple Store is and how many cores it has. I'm certain I want the extra RAM and I'm happy with 512GB storage, but I'm not sold on the jump from 2.9TB3.3 to 3.1TB3.4. Please help or give advice! The program at my #1 choice school lists applications such as parallels, autocad, matlab and other upper end functions in junior and senior classes but says the lowest tier MBP will do for the first two years, so as to provide context.
