Benchmark performance comparison: Galaxy S8+ vs Galaxy S9+

Benchmark comparisons aren’t something we usually do. In fact, we never bother with benchmarks, because most benchmarks simulate extreme use cases that don’t reflect how the everyday experience of using a device would be. And, well, if a phone’s software isn’t properly optimized, lag and stutter in regular operation make even the highest benchmark scores seem useless. Samsung’s phones are certainly guilty of dipping in performance even a month down the line, and the company’s flagship Galaxy S devices are affected as well. It’s not like the company can’t optimize things well enough, though. The post-Galaxy S6 Note series phones usually perform admirably months after you start using them, but the same level of optimization is yet to permeate the rest of Samsung’s smartphone lineup.

Where benchmarks matter is showing us just what kind of performance a new device is technically capable of compared to the one that came before, and it holds especially true for flagship phones, which come with a newer, more powerful/efficient processor every year. The Galaxy S9, for example, is powered by the Exynos 9810, while the Galaxy S8 (and Note 8) was powered by the Exynos 8895. The Exynos 9810 might be built on a 10 nm process like the Exynos 8895, but it does get new microprocessor cores and a more powerful GPU. Even the 10 nm process used for the 9810 is more refined and makes for better theoretical power efficiency and performance over chips built on the first-generation 10 nm process.

On the Galaxy S9+, you also get 6GB of RAM, while the Galaxy S8 and S8+ had to make do with 4GB of RAM, so the real-world user experience on the S9+ is noticeably better than the S8+. But where do these devices stand when it comes to benchmark performance? We decided to run a few popular benchmarks on the Galaxy S8+ and Galaxy S9+ to find out, and, unsurprisingly, the Galaxy S9+ came out on top in nearly all tests. We have even thrown in an internet speed test comparison over Wi-Fi for good measure (although these can vary wildly depending on the router the devices connect to and shouldn’t be taken too seriously).

We’ll just let the scores do the talking, however, so check those out by looking at the images below and let us know your thoughts in the comments. The Galaxy S8+ scores are on the left, and the S9+ scores are on the right in each picture. Unfortunately, we were unable to test the regular Galaxy S9 against a Galaxy S8, but since the S9 only gets less RAM, its benchmark scores should be similar to the S9+ on most accounts.

  • Wow! On paper, the S9+ obliterates the S8+! Still, I don't find it necessary to upgrade my S8+. Great article, AbhiIjeet, always a pleasure to read them.

        • Apple isn't going to give a Samsung site a review unit. In fact, Apple's most selective with review units, comes with being the top dog in the industry, a power even Samsung hasn't reached.

  • In real world usage they are same. Benchmarks are topics for forums and nothing else.

    • Agreed. Phones have been powerful enough for years . That's why manufacturers are screwing around with notches and curved displays, they have nowhere useful to add anymore to justify new phones.

    • Exactly, it's a worthless exercise given the speed of processors today. A phones performance is limited anyway by the speed of our finger! Lol. These tests are more about capability. For example the new SoCs can handle AR and AI a lot better than previous chips. This obsession with benchmark numbers that mean absolutely nothing when using the phone on a daily basis is just childish and there are a lot of children commenting here.

      • Yes I've used S9 (not plus) (for 3 days) and this phone have same speed as my S8, nothing special. As I said just a topics for forums.

      • mind elaborate what version Snapdragon or exynoss u own ?
        and how "much faster" betweem your S9+ vs S8 ?
        like opening chrome S9+ faster 3secs+ over S8+ ?
        i am curious because those speedtest vids on youtube showing similar speed between S9 vs S8

  • Hey Sammobile, I think you guys should mention anandtech's detailed comparison of the SoCs on your website. Their Exynos 9810-equipped Galaxy S9 produced extremely disappointing results in their tests.

  • Though benchmark tests don't mean a thing these days, looks you used a faulty s8 or an older version, because my s8plus running Oreo gives a 200k+ antutu result. I wonder why yours is so poor.

    • Agree. My S8 (Exynos 8895) has a high Antutu benchmark score of 201,117, w/ Android 8.0.

      This guys results are so last year (2017) lol.

  • Honestly, these scores aren't THAT much better than the S8+, especially now that it has Oreo. In fact, the GPU scores are very minimal improvements. Real world usage performance will most likely remain the same.

  • A lot of people are fantasising here about their last years phone. The difference between both processors AND between sd835 and 845 is huge. I have the Exynos Note8 and my wife has the Exynos S9 plus. I ran these tests on both and S9 really beats out my Note8 with ease. People are just justifying because they can't afford to upgrade. Benchmarks mean very little in real world use anyway. The difference in speed between a 2017 phone and a 2018 phone is tiny, but the scores are more to with capability than speed. Based on the S9 plus real world performance and the great camera, speakers and brighter screen in sunlight I will be upgrading my Note8 to Note9.

    • the computing power is huge, its like 40% increase (like editing 4K videos in phone which give much faster result)

      but like you already said in your post, "the difference in speed between 2017 vs 2018 is tiny" -> this what for most people matters and make most people think its not worth spend upgrade, as there will be new release each year with better/faster chipset anyway.

      Now i ask you what for high-performance/score if you not getting the improvement in daily usage ?
