Samsung Galaxy S9 Plus with Snapdragon 845 SoC appeared on AnTuTu, scoring a total of 265,267 points. Its predecessor Galaxy S8 Plus Snapdragon 835 variant had scored about 170,000 points. The tested variant has 6GB of RAM and 64GB of internal storage; other significant technical details did not emerge.
The Exynos 9810 variant of the Samsung Galaxy S9 has appeared on Geekbench, the Galaxy S9+ model had already appeared on the same platform several months ago; the scores are very different. Note that the device was not yet complete and that the low-performance mode was tested.
The scores are considerably different even compared to the Snapdragon 845 variant appeared on the same platform at the end of 2017. Although even in that case it is reasonable to assume a non-definitive hardware and software version, it is interesting to note that Exynos is more powerful in single-core than in multi-core, but the relative gap decreases significantly in the second case: SD845 scored 2422 and 8351, while E9810 3648 and 8894. In proportion are differences of 40 and 6.3 percent.
It is impossible to draw conclusions now because we do not know how the various platforms were final, but so far the discovered clues indicate that Samsung has really worked on the single-core performance of its processors.
