One of AnandTech's more in-depth coverage pieces last year was our analysis of the two different version of the Galaxy S9 and Galaxy Note9. Specifically we covered the quite large differences between units offered with Qualcomm’s Snapdragon 845 and Samsung’s own Exynos 9810.

This year again we’re seeing Samsung continue their dual-sourcing strategy in the new Galaxy S10. This time we’re pitting the new Qualcomm Snapdragon 855 against Samsung’s own new Exynos 9820. We were able to extensively benchmark the new Snapdragon 855 back at CES – however we don’t know much about the new Exynos 9820.

At last year’s Galaxy S9 reveal at MWC2018 we were able to benchmark the phone immediately after the press event. Unfortunately this year with Samsung dedicating the launch to a completely different event in San Francisco, we weren’t able to get our hands on the units immediately. It took a while, but with the help of some fellow colleagues over at TechRadar, I was able to briefly have access to both units of the Galaxy S10 and run some quick benchmarks.

I kept things to a minimum and opted to just run PCMark and Speedometer 2.0 – both benchmarks are some of my favourite in terms of representing the true perceived performance and experience of a smartphone. Both phones were set in performance mode and were running firmware as sampled by Samsung.

PCMark Work 2.0 - Web Browsing 2.0PCMark Work 2.0 - Web Browsing 2.0

In PCMark’s Web Browsing test, the new Galaxy S10s both perform well. What is interesting to see here is that compared to the scores we initially ran on Qualcomm’s reference device back in January, the Snapdragon 855 Galaxy S10 represents a notable uplift, and seems to be a better representation of the capability of the chip compared to the QRD.

It’s to be noted that the comparisons I’m making today are all on the new Android 9 firmwares – I don’t have updated figures for the Exynos S9 or the Snapdragon Note9, but have the latest numbers on the Snapdragon S9 and Exynos Note9, which should be identical to their sister series' counter-parts.

The new Exynos 9820 Galaxy S10 now showcases a large performance upgrade compared to last year’s Exynos 9810 units. The new chip’s figures are good and better than the Snapdragon 845, however aren’t able to match either the Snapdragon 855 nor the HiSilicon Kirin 980 – the latter two both based on Arm’s newest Cortex A76 CPU cores.

PCMark Work 2.0 - Video Editing PCMark Work 2.0 - Video Editing

The video editing test is less relevant nowadays as performance differences between different platforms are quite minor. Still the new Exynos still shows a distinct performance difference to the Snapdragon counter-part, similar to what we saw last year.

PCMark Work 2.0 - Writing 2.0PCMark Work 2.0 - Writing 2.0

The writing test is probably the single most important component of PCMark when it comes to representing the experienced performance of a device. The Snapdragon 855 Galaxy S10 falls in line with the QRD’s performance, which is excellent.

The new Exynos 9820 Galaxy S10 represents a major jump for Samsung, scoring double what we’ve seen on the Exynos 9810 units last year. Likely what this means is that Samsung has solved some of the most important performance issues plaguing the Exynos S9/Note9. The phone still lags behind the new Snapdragon 855 as well as the Kirin 980. We’re not sure if this continued difference is due to hardware or scheduler, and we won’t be able to find out until a more in-depth investigation at a later date.

PCMark Work 2.0 - Photo Editing 2.0PCMark Work 2.0 - Photo Editing 2.0

In the Photo Editing test we see the new Exynos 9820 similarly performing almost twice as well as last year’s Samsung silicon. Here it’s clearer that the difference is due to new improved scheduler reactivity as the workload isn’t necessarily throughput limited. The continued performance detriment to the Snapdragon and Kirin chipsets however still points our that Samsung’s APIs still aren’t as well optimised.

PCMark Work 2.0 - Data Manipulation PCMark Work 2.0 - Data Manipulation

Finally, the Data Manipulation score is more single-thread limited workload. Here, the new Snapdragon 855 Galaxy S10 takes the top spot among devices. The new Exynos 9820 doesn’t fall too far behind, and does represent a big boost over the Galaxy S9 in either versions.

Speedometer 2.0 - OS WebViewSpeedometer 2.0 - OS WebView

Switching over to a browser benchmark, the new Galaxy S10s both perform almost identically. The performance of the Snapdragon 855 is a bit better than the QRD we tested in January, however it’s still lagging behind the Kirin 980.

The Exynos 9820’s performance here represents a huge boost compared to the Exynos 9810. The score presented here not only represents the possibly much better scheduler, but also hardware improvements on the part of the new cluster and microarchitecture designs.

Performance looks “OK” for the Exynos – Though Snapdragon looks to be leading

Overall the new Galaxy S10s are both in line with expectations. The Snapdragon 855 Galaxy S10’s performance isn’t much of a surprise, as we had covered the chipset in detail at Qualcomm’s performance preview event. The Galaxy S10 actually performs better than the QRD – putting to rest some of the worries we had on the early platform. It’s to be noted that Qualcomm here still lags a tad behind HiSilicon’s Kirin 980 in some aspects, probably a result of the latter’s better memory latency.

The new Exynos 9820 performs significantly better than last year’s 9810. Here Samsung seems to have taken note of the scheduler slowness that has plagued the last 3 generations of Samsung SoCs. Besides some obvious software improvements, the new M4 microarchitecture also seems to have upped the performance. Samsung claims 20% better performance than the 9810, which looks to be reasonable.

Battery Life To Be Determined

Today’s results only represent a bare minimum in terms of benchmarking Samsung’s new devices. While the new Exynos 9820 can’t keep up to the Snapdragon 855 in terms of performance, it’s no longer such a stark difference as we saw last year.

Most importantly, there’s still one big open question: power efficiency. As we’ve covered in our preview of the Snapdragon 855, the new Cortex A76 derived cores on a new 7nm process node showcase some outstanding efficiency figures. HiSilicon’s Kirin 980 is able to power some of highest endurance flagship devices today, and I expect the Snapdragon 855 to be able to achieve the same. If the new Exynos is able to achieve the same is something we’ll have to find out at a later date. We have to remember that Samsung’s chipset not only has to fix its microarchitectural efficiency issues, but also comes with a process manufacturing disadvantage as the chip is produced on a (theoretically) inferior 8nm process.

Unfortunately we won’t have the Galaxy S10 in-house for review until after public availability on March 8th – so we’ll have to be a little more patient before we can post a more detailed analysis of Samsung’s new flagship devices.

    Let's keep it real, I highly doubt that the highly payed engineers at samsung didn't figure out those relatively simple solutions for the 9810, I am pretty sure they got a good reasoning why they setup the SOC control the way they did.

    In these kind of situations you need to be aware of the cultural differences.
    I've got the distinct impression samsung is being run in a very strict hierachy.
    If some high level manager says something, that's whats going to happen. And nobody is going to get into a discussion.
    Example: We have this new ssd controller that destroys all the competition. No matter the chip tyoe. Lets put it in all devices and keep the pricelevel in line with the competition. Nobody at Intels would accept that situation.

    And in this case, I can imagen some manager saying. Those anandtech guys. Boycot them... Done boss.

    It was the worst Soc and software implementation i've ever seen in any high-end phone, ever. Completely unacceptable, especially from such a massive company. Not fit for sale. The whole team who worked on it should have been fired. I had to get a Snapdragon 845 S9+ import. That appalling S9 Exynos SoC should have been a way bigger story on other tech news sites, but you can't trust "journalist" filth.

    The Exynos 9820 is still looking bad too, but at least it's looking a lot better than last years SoC, although that really isn't saying much.

    You make good points though you seem a little antagonistic. In my opinion in light of current events anyone who characterizes all journalists as "filth" casts themselves in a questionable light.
  • Lord of the Bored - Wednesday, February 27, 2019 - link

    The quotes were around journalist, not filth. He was calling people who claim to be journalists, but are actually just mouthpieces for some big company's marketing department, filth.
  • peevee - Monday, March 4, 2019 - link

    Speaking the undeniable fact that a lot of journalists these days are no better than paid trolls, or filth, puts the person in GOOD light with SMART people.
  • Spunjji - Friday, March 22, 2019 - link

    That "fact" is extremely deniable because you didn't define your claim. Is "a lot" a specific number or a proportion? Which area of journalism are you referring to? As it is you have said nothing whilst managing to *sound* as though you made a point, which is not the same as making one.

    I'd agree that a majority of tech "journalism" consists of creatively rewriting press releases and spewing platitudes about the latest product. You're saying "a lot of journalists" are no better than filth, though, and that's a much wider claim. It sounds akin to the "liberal media" propaganda foghorn being blown wherever ignorance reigns. If that's not the claim you're making then it would help to be more specific to avoid sounding like it is.

    It's really sad that these phones are still made with different SoCs depending on where you buy it, and without a choice by the buyer, really.

    Just make them all equal and figure out that nonsense with US Cellular networks. Just make all of them Snapdragon or make your own SoC actually work and use that everywhere. It's really a bad sign that they can't even make a phone that works globally.
  • Braincruser - Tuesday, February 26, 2019 - link

    I just ran this same benchmark on an s9+ with Exynos processor and the numbers I get match the snapdragon S9 version posted here.
    This is the score I get:
    Total score: 6902
    Web browsing 2.0: 7316
    Video editing: 5856
    Writing 2.0: 6313
    Photo editing 2.0: 11557
    Data Man: 5012

    Wow. So, you are saying that Sammy managed to fix that mess of a scheduler and the chip itself to a degree that it can compete with it's SD counterpart, only with software updates?? Nice... Don't take me wrong, but i'll have to test that out today on my friends S9+ and report back... I guess there is still hope Sammy can do the same with the Exynos 9820...
