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.

    There is also the issue of testing mobile phone platforms in general, and I try to make sure everyone is aware of this: Apple phones use different languages and frameworks. They also run a different operating system. This may cause some of the performance differences we see.

    Note that I’m not sandbagging on anyone, I am just encouraging an objective view of things.

    "Apple's CPUs are just far superior, see the SPEC scores for an even comparison of workload."

    Yes, but not to this degree, right? Speaking specifically about this browsing benchmark that shows iPhone 7 being superior to Galaxy S20, it absolutely does NOT translate into real-life experience. Galaxy S20 offers a vastly superior browsing experience to iPhone 7.

    Yeah far superior in SPEC2006. Big deal.
    In real life iPhones 7 doesn't feel any faster than a mid-range Android phone with something like an SD 710.

    You're comparing a phone released in september of 2016 with a SoC released in may of 2018. What exactly is your point?
  • Nicon0s - Wednesday, March 18, 2020 - link

    My point is that these benchmarks would show the SD 710 and much much weaker than an iphone 7 but in real world phone usage it isn't.
    And SD 710 was from the beginning a mid-range chip and it's found even now in phones that are much cheaper then an iphone 7.

    Is the phone so plain that Anandtech only shows 1 picture of it?
  • yetanotherhuman - Friday, March 13, 2020 - link

    It'll be an enormous rectangle with almost all screen at the front and delicate rounded edges that prevent you from using a screen protector. Everything is just copy and paste these days, with very anti-consumer designs

    Places like the the Verge cover more the look of the phone. This website covers more the performance characteristics of the phone. Why is this bad? Also, the title said this: "Quick Performance Preview". It did not say general review.
  • BushLin - Friday, March 13, 2020 - link

    It's ok, you will see a heavy focus on the size of the bezels when arstechnica review the handset.
  • SafraneIt - Friday, March 13, 2020 - link

    OT: Will you review the Surface Pro X? Or at least benchmark its "Microsoft SQ1" CPU?
    It is probably the highest power CPU available from Snapdragon.
