GPU Performance & Power

On the GPU side of things, Qualcomm has long been leading the benchmark charts with the help of their in-house Adreno GPU architecture. With the Galaxy S10, we again see a new round of Adreno vs Mali in the Snapdragon and Exynos variants of the phone.

The Adreno 640 in the Snapdragon 855 has relatively conservative performance targets this generation. Here Qualcomm promises 20% better performance even though the GPU itself has a reported 50% more execution units. What has happened is that Qualcomm has dropped the clock frequency from 710MHz down to 585MHz, account for where most of that theoretical GPU performance is missing. The rationale here is to be able to run wider and slower, and thus more efficiently.

On the Exynos side of things, the new chip adopts a new Mali G76MP12 GPU clocked in at up to 702MHz. We’re already seen the GPU inside of the Kirin 980, however for whatever reason Samsung S.LSI has always been able to achieve better results than HiSilicon for several generations in a row, so it’ll be interesting to see how these two chipsets differ.

Starting off with the 3Dmark Sling Shot Extreme Unlimited test suite, the Physics workload is mostly a CPU bound test within a GPU thermally constrained scenario.

The Exynos 9820 surprisingly takes the performance lead between both Galaxy S10 units. The result here is a very big change compared to previous generation Exynos SoCs. I hadn’t had the time to investigate if this is actually caused by improvements of the new M4 core or if the workload is being scheduled on the A75 cores. Both peak performance and sustained performance here are very good and are only beaten by Kirin 980 devices.

The Snapdragon 855 Galaxy S10 also posts excellent peak perf results, however the CPU seem to throttle quite a bit more, falling in line with what last year’s Snapdragon 845 devices were scoring.

In the Graphics score of the workload, we come back to the familiar dominance of Qualcomm GPUs. What is interesting to see here is that both Galaxy S10 units sport worse sustained performance than the Note9 with last year’s chipsets. Most likely this is due to different thermal limits on these two Samsung devices.

In the new GFXBench Aztec Ruins tests, the Exynos unit takes the lead in terms of sustained performance in the High variant test, only beaten by Apple’s newest iPhones. The phone doesn’t seem to reproduce the same lead in the Normal variant and subsequently slightly trails the Snapdragon 855 version. In sustained performance, the Exynos S10 beats last year’s predecessors, however the Qualcomm chip merely matches some of the better Snapdragon 845 devices from last year.

GFXBench Manhattan 3.1 Off-screen

In Manhattan 3.1 Off-screen, we see both S10’s neck-in-neck in peak performance, and sustained performance also doesn’t seem all that different. The Exynos variant again shows big leaps over last year’s G72MP18 GPU, and the Qualcomm variant again is only able to match or actually lose out to some of the more thermally aggressive Snapdragon 845 units from last year.

Looking at the power consumption and efficiency tables in Manhattan 3.1, we see both devices showcase quite similar characteristics. Performance is very close in both chipsets, with also very similar power consumption within 220mW of each other. The efficiency also is quite close to each other. Interestingly both Qualcomm and Samsung weren’t able to close the gap to Apple’s latest iPhones and the A12 which still has a considerable performance and power efficiency lead.

For the Exynos chipset, it’s also unfortunate to see that absolute power has gone up by 1W, meaning the device will heat up faster, even though performance and efficiency is better.

GFXBench T-Rex 2.7 Off-screen

In T-Rex we again see both chipsets perform very similarly with similar sustained performance figures.

In the power end efficiency tables we however see a big difference between the two devices. Here Qualcomm is able to clearly achieve lower power and higher efficiency than the Exynos.

One thing that I note on both Galaxy S10 units is that I again saw some very odd thermal behaviour on the part of the Qualcomm unit. Just like we measured on the Note9 a few months ago, the Qualcomm Galaxy S10+ reached much higher initial temperatures than the Exynos S10+. I measured peak skin temperatures on the front screen near the SoC nearing 49°C on the S855 unit while the E9820 peaked around 43°C. Again, much like last year, this seems to be a time-bound boost mechanism as after a certain period of around 20 minutes the Snapdragon unit throttles down to a sustained 42-43°C. What this means is that the Snapdragon unit has higher (longer) peak performance figures at a cost of a hotter device, before both devices equalise at a sustained ~42°C.

Overall, the Snapdragon unit this year does still have a performance and efficiency lead, however the gap has been narrowed compared to what we’ve seen in the past years. The new Mali G76 looks to have made solid improvements, and ALU heavy workloads in particular have seen very large leaps compared to the Exynos 9810.

The Adreno 640 this generation just seems quite conservative – Apple has taken Qualcomm’s performance crown in mobile and most importantly also the efficiency crown. Both the Snapdragon 855 and A12 are both manufactured on the same process node so it’s a valid Dragon-to-Apples comparison, and here Qualcomm is beaten by such a significant margin of which in the past we’ve only been used to seeing Qualcomm beat Arm with. For the next generation, we thus hope both Qualcomm and Arm will be able to show more significant jumps in both performance and efficiency. Samsung’s own GPU is also a wildcard, however I’m not expecting to see this productised in next year’s Exynos.

    As the bloatware typically doesn't impact my daily usage of the device nor consume a significant portion of the RAM/storage, I don't mind it. I actually find myself using much of the "extra" bloat they provide with the option to disable the ones I don't.

    When I use a stock AOSP build, I'm always searching for a feature or function that comes standard on Samsung....

    Go in and disable it.

    If you're really serious, root it, kill it and be done with it.

    The Galaxy line have good hardware. Software can be dealt with.

    I didn't buy my laptop for Windows 10, nor can I control what Dell puts on it, but I can certainly take it off.

    Yeah, good luck formatting and installing a stock OS from an iso like you can with your dell laptop.

    What an asinine comment.

    Dude have you ever rooted a phone? That's literally what you can do. Not an ISO but flash a Zip file and completely change your OS. The S10 is new and is pretty locked down, but some devs have already managed to root the thing and in the next couple months custom ROMs will emerge. It was like that for many Samsung phones on the past. The devs over at XDA have always manage to get root and custom ROMs on Samsung phones despite their attempts and totally locking down the phone.
    What an ignorant comment.

    I used to think the same thing, still kinda do, but I just hide or disable their icons, doesn't really make a difference, Galaxy S9 still runs smooth and quick. Reply

    I upgraded from my S5 to the S10e at launch (T-Mobile, S855, 6GB/128GB). To be really honest, I was disappointed out of the box. The higher power button, locked bixby button, bloatware, default camera/video settings.

    The first real improvement I noticed was that all my apps opened instantly as opposed to waiting several seconds on my S5 (it was old and slower than when new, despite resetting the OS and trying difference ROMs).

    The second improvement was the ridiculous battery life. I'm not a "power user" when it comes to cell phones. Text/email, pictures, videos, podcasts/music, and some web browsing. But still, 60% battery life at the end of every day (15hrs without charging) amazes me.

    Now after a month of tweaking everything to my liking, I'm really happy with the phone overall. The speaker quality is really impressive - it's super loud without distorting much. The screen auto-brightness has adapted to my settings per app and depending on ambient light. The camera is only slightly disappointing. I must not hold the camera still enough, because a lot of my shots end up blurry/smeary when zooming in. I still need to work on dialing in those settings and trying some other camera mods.

    I forgot to add that it felt a lot smaller in my hand (that's what she said) than my S5 due to the smaller overall bezel width. Now it's a lot more comfortable to use. Reply

    I also made the jump from the S5 to the S10, though I went with the regular S10, not the e. Not a single issue for me in any way(Snapdragon version, AT&T version). While there is still a fair amount of pre-installed apps, it doesn't feel as bloated as the S5 did with true garbage that I would never use but could not be uninstalled. Reply

    Part of your battery life issue could be due to an old battery in the S5. But manufacturers and Google certainly seem to plan obsolescence - ever higher specs are needed to keep up with the OS and bloatware. Reply

    I was on my 3rd new battery, so it wasn't that. Reply
