While apparently Samsung has done everything it can to ensure enduring user experience, the latest standards do not look very good.
According to the AnandTech team, they have put both smartphones in their standard tests and, unfortunately, the Snapdragon 855 version of the Galaxy S10 has managed to outperform the Exynos 9820 with a considerable margin.
In terms of editing videos using the standard PCMark Work 2.0, Snapdragon varied 6.545 points versus Exynos, marking 5.596.
As far as photo editing is concerned, the gap is even broader, with the Snapdragon model recording 17,496 against 11,412 of Exynos.
Now, these are just test results and do not necessarily create the full reality.
