Speed and memory
In our performance index the Intel HD Graphics 520 (integrated) scores 0.9 and the GeForce GT 710 scores 0.8, which makes the Intel HD Graphics 520 (integrated) about 13% faster. That is a visible but modest gap, usually 5 to 10 fps in a game that runs at 60.
The Intel HD Graphics 520 (integrated) has shared GB of video memory and the GeForce GT 710 has 1 GB. That is a small difference and unlikely to decide anything.
In our estimates for popular games at 1080p on High, the biggest gap is in Red Dead Redemption 2 (4 against 2 fps), and the smallest is in Fortnite (13 against 12 fps). Games that are light enough to run above 200 fps on both cards show little difference at all.
