Speed and memory
The GeForce GTX 1050 Ti and the Radeon 890M (integrated) are within a few percent of each other for gaming in our model, so you will not see a difference in play.
The GeForce GTX 1050 Ti has 4 GB of video memory and the Radeon 890M (integrated) has shared 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 Call of Duty (11 against 16 fps), and the smallest is in Red Dead Redemption 2 (21 against 22 fps). Games that are light enough to run above 200 fps on both cards show little difference at all.
