Can my 27" imac (late 2013) run an eGPU?

I would like to run a program called leapfrog geo off my computer. Needs to run off windows 10, which I have a partion for via bootcamp. All other computer components are fine to run this program off besides the GPU.

I belive that you can run an external GPU to run these processing heavy programs. I am just unsure of the compatibility with the intel chip (i3) and the eGPUs.

Another drama I think I migh have is the thunderbolt port. Have been looking online to try and work out which thunderbolt port the computer has (1 or 2?) no clear answers I can find.

Basically need some guidence to what I need to do to be able to run this program. Any help will be greatly apreciated.
