First Galaxy S10+ benchmarks suggest record-breaking performance

Well, technically, we have the S10+ to test, but with identical hardware under the hood, we'd imagine these results would be representative of both models.
The version we have on hand is an international one, and so it's powered by the Exynos 9 9820 chipset. That means the S10+ benchmark results below may differ slightly from what the Snapdragon 855-powered S10 may offer in the US, but for the most part, we'd expect both models to offer almost identical performance.
We've run a few popular benchmarks, including AnTuTu (system), Geekbench 4 (CPU), GFXBench (graphics) and JetStream (web), to test different aspects of the system. What we found is that this new Galaxy flagship is a notable improvement over its predecessor (S9 and Note 9). Also, the new S10 phones are probably the fastest Android phones right now!
The new processor, along with the faster storage probably play the biggest role in the superb system performance that AnTuTu detects in the S10+. Compared to the Note 9, the S10+ is vastly ahead with a score that is the staggering 35% bigger! The OnePlus 6T, being a mid-season upgrade, comes a bit closer, but is still behind. Only the iPhone XS manages to keep its cool and retain a leading position, but not by a lot.
CPU benchmark
In terms of multi-core performance, the difference isn't that big, but the S10+ is still ahead of the Android competition. Apple's A12 Bionic CPU in the iPhone XS remains unreachable for now.
Graphics benchmark
Now, let's take a look at graphics performance, which is by far the most important metric for gamers. For that, we're looking at the GFXBench scores. The Manhattan 3.1 test used to be very demanding, but these days we're starting to see the best Android flagships almost max it out. This is indeed the case with the S10+ and the Mali-G76 MP12 GPU that's part of the Exynos 9 package. It manages to achieve 57 fps on average, which is quite good and can rarely be reached by other Android phones.
