Which Graphics Card is Better?

This is more a question out of curiosity, as on my PC I am using a graphics card that's in the PCI express slot instead of the graphics card that is built into the motherboard. So I wanted to know if the graphics card in the PCI slot is much better than the one on the motherboard.
So the one in the PCI slot in a Nvidia GeForce GT 710. And the motherboard details are:
Manufacturer: ASUSTeK COMPUTER INC.
Model: PRIME H310M-A (LGA1151)
Version: Rev X.0x
Chipset Vendor: Intel
Chipset Model: Coffee Lake
Chipset Revision: 07
Southbridge Vendor: Intel
Southbridge Model: H310
Southbridge Revision: 10
Hopefully graphics card info can be got from that data, this is where my computer knowledge isn't so good, any information is much appreciated.

The UHD 610 integrated graphics are around equal to the GT 710 which is an older entry level Graphics Card.

You could put in a CPU with UHD 630 graphics which would actually be slightly better than a GT 710.

OK great thats good to know. Thanks for the info.

a $200 gtx 1060 would be a better upgrade than a cpu with a minor upgrade on the integrated video
