The benchmarks come courtesy of Geekbench, and show that the Galaxy S9 with a Snapdragon 845 processor putting up single- and multi-core scores of 2455 and 8312 respectively. Those numbers compare favorably to our own numbers from a reference Snapdragon 845 smartphone, which came in at 2476 and 8411 respectively.
While those numbers are no doubt excellent for an Android smartphone, the Samsung Exynos 9810 put up single- and multi-core scores of 3717 and 8839 respectively. That is a huge performance difference in single-core performance, and that's even considering the fact that the Exynos 9810 was "hindered" with just 4GB of RAM compared to 6GB for the Snapdragon 845 example.
We must take into account, however, that even with the Exynos 9810's knockout performance compared to the Snapdragon 845 in the cross-platform Geekbench benchmark, they both fall far short of the iPhone X, which is powered by Apple's A11 SoC. That smartphone was able to put up single- and multi-core numbers of 4206 and 10315 respectively.
We must caution that Geekbench is just one performance metric for the Galaxy S9's performance, and doesn’t take into account graphics performance. The Adreno 630 GPU in the Snapdragon 845 is averaging a 20 to 30+ percent percentage gain over the Snapdragon 835's Adreno 530 in graphics benchmarks. We have yet to see any comprehensive GPU figures for the Exynos 9810 to compare.
Samsung will unveil the Galaxy S9 and Galaxy S9 Plus on February 25th at an "Unpacked" event at the Mobile World Congress. Galaxy S9 series smartphones for the U.S. and Chinese market will feature the Snapdragon 845, while all other world markets will get the Exynos 9810.
