According to the folks at AnandTech, they have put both phones through their paces on benchmarks and unfortunately, the Snapdragon 855 version of the Galaxy S10 has managed to outperform its Exynos 9820 variant by a considerable margin. In terms of video editing using the PCMark Work 2.0 benchmark, the Snapdragon variant scored 6,545 points versus the Exynos which scored 5,596.
In terms of photo editing, the gap is even wider where the Snapdragon model scored 17,496 against the Exynos’ 11,412. Now these are just benchmark scores and don’t necessarily paint the whole picture. After all there’s a good chance that all the phones in your region will be using the same chipset, so it’s not as if your friend’s Galaxy S10 will outperform yours (unless they were bought from different places).
Also to be fair, we’re not sure how big a difference there will be in real-life performance and handling, so while the benchmarks do suggest that the Snapdragon variant is a much powerful handset, perhaps in real-life the differences might not be as obvious.
