Samsung's Galaxy S20 series phones have been available since last Friday in markets such as the US. And earlier this week we also finally received a unit, in the form of a North American, Snapdragon 865-based Galaxy S20 Ultra. While our review is already underway, we’re also still waiting for public availability in Europe in order to get our hands on our Rest of World, Exynos 990 variant, so that we can take a comprehensive look at both variants of the S20 series. As we've seen in previous years, there have been some pretty significant differences between the Snapdragon and Exynos models at times, thanks to the SoC selection impacting everything from performance to image processing.

But first things first: since we have a bit of a lead time with the Snapdragon unit, we wanted to at least publish the performance figures for this model ahead of the full review, to temporarily satisfy everyone’s curiosity on at least this aspect of the phone.

System Performance

System performance of the new Galaxy S20 Ultra is an interesting topic, as there are several new aspects to this year’s flagship phone. The one big difference that trumps every other addition is the fact that Samsung has been able to integrate a new 120Hz refresh rate display. This change alone puts the new S20 series far ahead of other mainstream phones in the market, and the new experience is fantastic.

Besides the new higher refresh rate screen, we’re also naturally seeing the upgrade to newer generation SoCs. In this first instance, we’re testing the Snapdragon 865 variant of the Galaxy S20 Ultra. For their latest flagship SoC, Qualcomm adopted the new Cortex-A77 CPU cores, promising to bring 20-25% higher performance over its predecessor.

Finally, we do have to remember that Samsung has a “performance” feature in its battery settings, which increases the aggressiveness of the scheduler to fully unlock the performance of the phone. Usually we test Samsung phones with this option enabled, both in our performance as well as battery life testing.

Starting off with our usual system performance tests, these evaluations are highly sensitive to the responsiveness of the phone, which is tied to the aggressiveness of the DVFS and scheduler of the CPUs. For the Galaxy S20 Ultra, we have four score combinations, showcasing the 60 and 120Hz modes, as well as the “High Performance” mode on or off.

PCMark Work 2.0 - Web Browsing 2.0

The web browsing test in PCMark is quite sensitive to performance responsiveness, and in this regard, the new Snapdragon 865 doesn’t disappoint. Switching between the 60 and 120Hz modes, we see a notable increase in fluidity, and this is picked up by the benchmark.

At the highest performing settings, the new Galaxy S20 Ultra even outperforms the QRD865 platform that we tested back in December. This was quite surprising, as I wasn't expecting commercial devices to ship with as aggressive settings as that phone’s “Performance Mode”, which did seem tad aggressive.

PCMark Work 2.0 - Video Editing

The video editing test has largely lost its performance scaling usefulness, but still is able to pick up the new 120Hz mode of the S20U, representing a jump ahead of any other phone in the market.

PCMark Work 2.0 - Writing 2.0

The writing sub-test is very important in terms of being a representation of every-day snappiness of a phone, and the Galaxy S20 Ultra here tops the charts, falling in line with the best scores from the QRD865 as well as now slightly leaping ahead of Huawei’s Mate 30 Pro.

PCMark Work 2.0 - Photo Editing 2.0

The photo editing test similarly is scaling up in performance across the different setting configurations, showcasing fantastic performance.

PCMark Work 2.0 - Data Manipulation

The data manipulation score also seemingly is tied to the framerate achieved during the test, and the 120Hz mode of the S20U leads all other devices.

PCMark Work 2.0 - Performance

In the overall results, no matter what setting you’re using, the Galaxy S20 Ultra with the Snapdragon 865 tops all other commercially available Android phones out there, and at its peak settings, it even outperforms the QRD865 in its aggressive performance mode.

I did some quick testing of the DVFS aggressiveness between the optimized and performance modes, and was surprised to see no difference in the resulting scaling behavior. This means that the performance differences must arrive from the overall more aggressive scheduling, rather than scaling up to higher frequencies sooner. We’ll go over this aspect in more detail in the full review.

Speedometer 2.0 - OS WebView WebXPRT 3 - OS WebView JetStream 2 - OS Webview

In all our three web tests, we see the S20 Ultra in line with what the QRD865 was able to achieve, with some slight leads in WebXPRT 3. The Cortex-A77 seemingly doesn’t improve its instruction throughput very much in high instruction pressure heavy workloads such as the web-based JS benchmarks, so that’s possibly why we aren’t seeing that large increases here.

CPU Performance & Power

Our power testing back in December on the QRD865 platform wasn't quite as accurate as I would have hoped for, as the phone's power management funcitonality as well PMIC calibration weren’t quite polished. I had opted to publish numbers on the more pessimistic side of the scale, and I’m glad I did as it does turn out that the new chipset performs quite a bit better in actual commercial devices, including of course the S20 Ultra.

These new figures mean that the Snapdragon 865 actually does not behave as expected – we had been anticipating it requiring more power to achieve its higher performance points – and instead Qualcomm has managed to reduce absolute power all while increasing the performance. As a result, we’re seeing a much larger generational improvement in the energy efficiency of the chip. The new “middle” cores of the Snapdragon 865 also outperform the performance cores of the Snapdragon 855, and that does signify for quite a large multi-threaded performance boost.

We’ll be going over the detailed results as well as include an analysis of the Exynos 990 chip in our full review, but for now, it seems that the Snapdragon 865 is an excellent chipset, and will serve as a great base for 2020 devices.

    Please, use updated results (PCMark work 2.0) of S10+(exynos) when you compare it to newer devices. I think your data is even android 9(not 10) for S10/S10+ devices. Here's what I get right now on my S10+ (exynos 9820, 12 GB version) updated to the latest official firmware, performance mode:

    web browsing 2.0 my S10+/P: 9174 AT S10+(E9820): 7746
    video editing my S10+/P: 6113 AT S10+(E9820): 5476
    writing 2.0 my S10+/P: 9683 AT S10+(E9820): 9114
    photo editing 2.0 my S10+/P: 20455 AT S10+(E9820): 11019
    data manipulation my S10+/P: 6334 AT S10+(E9820): 5817
    performance my S10+/P: 9321 AT S10+(E9820): 7531

    See how much performance your result is missing? Photo editing 2.0 is almost 50% of its actual value... No point in comparing it with S20 ultra.

    I have an iPhone 11 Pro Max and I can tell you without question that the phone has serious thermal throttling issues. As an example, I can play Dota Underlords at a fluid 60 fps until the phone warms up, and then things gradually drop to less than 15 fps. It is a very unpleasant experience.

    Furthermore I am wondering if Apple is doing something to make the A13 appear better then it actually is. Don’t get me wrong, the iPhone 11 Pro Max and the A13 are both fantastic, but there are many odd quirks about both. In non gaming scenarios, the phone performs quite well, and I have no complaints thus far. However, in gaming scenarios the phone gets quite warm and throttles.

    In essence you'd appreciate lower peak performance if it meant fewer throttling issues? I get the feeling lots of hardware is tends towards the running-too-hot spectrum, perhaps because it benchmarks better.

    The thing is that for really intermittent stuff - UI animation, basically - it might be OK to have an absurdly high power ceiling since it's so short-term. Then again, you'd hope UI animation isn't a heavy load in the first place...

    Yes, it seems like the ramp up and throttling are both too aggressive. If the phone were clocked a bit lower, I imagine there wouldn’t be throttling issues at all except in extreme environments. I wish Apple offered a bit more control over this. Reply

    We should worry about nonsense like "UI animations" AFTER the devices are already fast, which they're not. Reply

    I play a lot of heavy games on my 11 pro max, including fortnite and never experienced what you describe. From 60 to less than 15? :)
    You are playing only dota underlords? Because there are some games that misbehave like for example magic duels - it drains x3 fortnite high@60fps and heats the phone like no tomorrow. This is literally the only game I ever had issue with and I got around atleast 30 games and 15-20 from them are one of the most demanding on the app store.

    3DMark Physics is essentially a test of (number of cores)*(frequency). It's not really a test of the GPU, and the way it tests a CPU is mostly not representative of most code.

    Apple has looked worse on it than any other benchmark since smartphones started for precisely this reason -- Apple ships with fewer cores and frequently clocked lower than Android.

    All benchmarks are ideal scenarios. Real life code never matched the theoretical advantages of DX12 vs DX11 for example. Apple looks worse in this test because it's also about thermals. Apple's high performance SoC's Achilles' heel is throttling under sustained workloads.

    User eek2121 describes above how the mighty pro max drops to unplayable 15fps becacuse it runs too hot.

    orrr he have a defective device that is misbehaving, or he have a totally f up software that cries for clear reinstall without any backup restores. One user is one user + you can't even prove what he says is true. You can read Andrei's review and see how the pro max behaves when stressed. Reply
