Conclusion & End Remarks

We’re coming to an end of what’s a very long review for what probably the most awaited and important Android devices of 2020. Samsung has made several promises as to what the S20 series brings, with the majority of the hype being surrounded around the new cameras, with the other key point being the 120Hz display of the phone.

Starting off with the general design updates of the S20 series, I’m actually extremely happy as to what Samsung was able to achieve with the smaller S20 and S20+ phones, and in part with the S20 Ultra. Samsung’s flattening of the display along with the larger curvatures of the back glass means that, ergonomically, the new phones are a very big improvement over the last few Galaxy flagship generations, allowing the phones to feel smaller than they are – even the humongous Ultra.

The S20 Ultra is in a class of its own when it comes to its size. It’s bigger, thicker, and just feels heftier than anything else Samsung has brought to market in the flagship category. I’m sure there’s plenty people will very much welcome these devices as they’re willing to use bigger and bigger phones, though I’m more prone to stick with the S10+, as I feel the Ultra is just a tad too large.

The other drawback of the Ultra is the camera bump. It’s not that I have anything against camera bumps, it’s just that I feel Samsung could have implemented it with better design elements – particularly the “gasket” – and the gaps around the camera protrusion feels cheap and is very prone to collecting dust. I didn’t have the same reservations about the S20+’s camera design, as that one's perfectly fine and reasonable in my opinion.

The screens of the S20s are all excellent in terms of their quality. The highlight feature of the phones here is simply the 120Hz ultra-high refresh rate. It’s an amazing feature that by itself is able to differentiate the experience of the S20 series, bringing you a much smoother device experience than ever before.

The performance of the S20 series is also excellent. Both the Snapdragon 865 and the Exynos 990 are able to deliver top-notch system performance on the new phones, although the Snapdragon does have a slight edge. Together with the 120Hz refresh rate, these are the snappiest, most responsive devices on the market right now – no contest.

However, the 120Hz refresh does come with quite the battery life cost. Expect a 20-25% reduction in battery life when you use the feature. Here even though the new phones come with extra big batteries, going up to 5000mAh on the S20 Ultra, it’s not sufficient to counteract the high refresh rate power draw. And if you’re coming from a previous generation flagship phone, the net result will be a battery life downgrade. It’s possible that Samsung could improve things with firmware updates and actually introduce a switching refresh rate mechanism to improve the current inefficient system – but we don’t know if and when they’re going to do that.

The power efficiency differences between the Snapdragon and Exynos are acceptable in everyday usage, however if you’re a power user, particularly in gaming, the Exynos 990 won’t fare very well. The M5 CPU is a disappointment and isn’t competitive with the Cortex-A77 cores of the Snapdragon. But at least it’s the last generation of Exynos SoC having to live with such a disadvantage. The GPU performance of the SoC is also very disappointing, as the long-term performance will only be around half of the Snapdragon models.

Then there’s the cameras. Samsung put such an emphasis on the camera capabilities of these phones that frankly we expected the most amazing results ever. In my mind in particular I had expected for Samsung to compete with Huawei in terms of picture quality, both in daylight and in low-light.

In daylight, the one strength of the phones that does materialize is the S20 Ultra’s telephoto module. The sheer hardware prowess of this camera is leaps ahead of other devices in the market right now. Sure, Samsung went a bit too far with proclaiming it’s able to achieve up to 100x zoom – those pictures are just a blurry mess. But it does fare very well at 10-20x magnification, and provides some shots that you normally wouldn’t think possible out of a phone.

The main camera sensors on the other hand I feel fall short of the high expectations. Yes, they are better than what we see on the S10 series, however Samsung here is still falling short of proving the same quality that Apple achieves on the iPhone 11 – and it’s also optically inferior to Huawei’s newest devices. I just don’t quite see why the 108MP sensor on the S20 Ultra had to be an 108MP sensor, as I don’t feel that number of pixels translates in anything meaningful in any of the camera usages of the S20 Ultra. In fact, more often than not, the S20+’s 64MP camera unit is able to take more detailed pictures.

The S20+’s 12+64MP combination is I think more versatile than that of the S20 Ultra, and the area where this shows the most is in the 1.2-3.5x zoom range, where the Ultra just falls apart, but the S20+ still is able to take perfectly detailed pictures. The ultra-wide-angle’s reduced resolution from 16MP to 12MP is a straight downgrade for daylight pictures, it does however make this up with better low-light pictures.

Then there’s low-light, which is just a massive mixed bag of results. Here it’s clearly a matter of the software not being optimized, as sometimes all the S20 perform worse than the S10 phones. Yes, in the perfect conditions the phones are able to shine – particularly the Exynos models, which currently have much better low-light camera calibrations and processing – but even in that best-case scenario Samsung is far behind the results that Huawei is able to achieve.

Megalomania Devices - But Still Good Phones

I've taken to calling the S20 series megalomania devices because, $1400 price tags and all, they’re overpromising and underdelivering – however that doesn’t mean they’re bad phones. Other than the display size and the excellent zoom module, I don’t really see the value in the S20 Ultra over the S20+. The 108MP camera in particular feels underutilized. Given the steep price premium over the S20+, I’m having a hard time rationalizing this phone over its smaller siblings.

The S20+ I feel is a proper successor to the S10+, and I’m even willing to switch over to it as a daily device. The 120Hz screen remains incredible no matter the battery life impact, and the cameras are still plenty good, even if not class-leading. The users in Snapdragon markets in particular end up with a device that makes very few compromises and is seemingly worthy of being a top class 2020 flagship. I just hope that Samsung will be able to resolve the camera discrepancies between the different models, as well as generally improve the camera picture quality over the coming months. If they achieve this, then I feel that the new phones would warrant their release price tags.

    I'm really amazed in the fact that the iPhone XR is still beating snapdragon 865 in GFXBench in both peak and sustained performance. I am hoping the OnePlus 8 has better sustained performance.

    Amazing review! Always wait for this one before getting a new samsung. And I won't be getting any of the s20 phones. For me the kind of feel like "beta" phones. The 120hz which is not quite ready for 1440p yet, the underutilized 108mp camera, the space zoom which is blurry, the camera hole still being there the big camera bump and so on. I think all these features and more could be way more refined with the next galaxy s which I'll be waiting for. Also the poor exynos 990 performance especially the GPU part is just unacceptable to me. Especially with it probably being a lot better next year, so I'll skip this year

    Thanks Andrei, really good review!

    I have read many users complain about extra crazy post-processing on the S10/S20 series when there is a face detected in the frame. i.e. the phone will apply an aggressive 'smooth skin' filter that you can't disable unless you shoot RAW. I was hoping that your review might touch on this however there were no people in your example shots so perhaps you didn't get a chance to experience the problem. I wonder if you have heard of this issue and can replicate it yourself with the S20 range?

    Hi Andrei, did you also run the bandwidth and MLP sweeps from previous reviews? Last year you noted the Snapdragon 855/A76 had peculiar behavior in the L1, and it would be also interesting to see if there are any MLP changes in both the SD865 and the Exynos.

    Also, any idea why the new scores for these in 403.gcc seems to be worse than their previous generation products? In particular the score for the SD865 in these S20s is substantially worse than the SD865 score from the QRD preview article.
  • Andrei Frumusanu - Saturday, April 4, 2020 - link

    Yes I know. I don't know why that happens. I also got a V60 now and the scores there are higher, I'm wondering if there's something with Samsungs shared libraries.

    What type of compile flags are used for these binaries? Are they the same for all of the tested binaries (or even same binary on each given platform)? Are LTO or PGO used (and if not why not)?

    I'm also not convinced of this statement from the article:

    "I had mentioned that the 7LPP process is quite a wildcard in the comparisons here. Luckily, I’ve been able to get my hands on a Snapdragon 765G, another SoC that’s manufactured on Samsung’s EUV process. It’s also quite a nice comparison as we’re able to compare that chip’s performance A76 cores at 2.4GHz to the middle A76 cores of the Exynos 990 which run at 2.5GHz. Performance and power between the two chips here pretty much match each other, and a clearly worse than other TSMC A76-based SoCs, especially the Kirin 990’s. The only conclusion here is that Samsung’s 7LPP node is quite behind TSMC’s N7/N7P/N7+ nodes when it comes to power efficiency – anywhere from 20 to 30%."

    Both the energy consumed and the performance scores for both of these A76's seem to also very closely track the "mid" 2.43Ghz A76's on the TSMC-fabbed SD855 - all of which have similar L2's and similar frequencies, but possibly differ significantly (to the point of being suboptimal on latency) on the memory hierarchy and SoC beyond that - which greatly affects many of the SPEC workloads. All of these may also have implementation targets. Given this, is it really conclusive that the Samsung process is truly 20-30% worse in energy efficiency? Granted, things will probably not look pretty next year when TSMC is on a true 5nm and Samsung is not.

    The test is just -Ofast without any other addition. LTO wasn't/isn't in a good state on the Android NDK - it's something to look into in maybe a new binary revision.

    As for the 855 figures, well, that's also on an earlier 7nm. HiSilicon did a lot better in terms of they physical implementation. If not against N7, 7LPP clearly has a disadvantage against N7P/N7+.
  • Andrei Frumusanu - Saturday, April 4, 2020 - link

    I'll add them in, that test takes a whole day and I needed the phones doing battery tests and other stuff.

    Again, your S10+ Exynos results in pc mark are false as of 2020. In performance mode I easily get 9500 work 2.0 overall, about 9600 in browser bench, 21K in photo editing. PC mark in general is inconsistent, irrelevant benchmark, not representative of actual performance in daily usage. The same about these ancient SPEC synthetics. No one uses these for performance evaluation now.
