System Performance

Another Snapdragon 845 device, another system performance section to dwell into. By now following the Galaxy S9 review and Mi MIX 2S review we should have some clear expectations of how the OnePlus 6 should perform. In my MIS 2S review in particular I was very vocal about how superbly the phone performed in terms of performance, and attributed this to a great software implementation on the side of SoC. The OnePlus 6 very much deserves the same praise as it not only has the same extraordinary snappiness, but actually ever so slightly manages to beat the MIX 2S in some cases.

PCMark Work 2.0 - Web Browsing 2.0

Starting off with PCMark’s Web Browsing test, the OnePlus 6 is very much within the top scorers in terms of performance.

PCMark Work 2.0 - Video Editing

The video editing test again is mostly performing as expected.

PCMark Work 2.0 - Writing 2.0

In the Writing 2.0 test which uses Android APIs and does operations such as text editing and PDF rendering the OnePlus 6 actually manages to take the top spot in terms of performance. This test alone correlates extremely well with overall system performance of a phone and the OP6 taking first place is indeed very well representative of the phone’s feel.

PCMark Work 2.0 - Photo Editing 2.0

Photo editing test, alongside the Mi MIX 2S also takes top spots among current devices.

PCMark Work 2.0 - Data Manipulation

The data manipulation score averages out among top Snapdragon 845 devices.

Finally the total score matches the Mi MIX 2S. There’s not much more to say here other than Qualcomm’s scheduler improvements in the S845 BSP have really paid off this generation and this directly results in excellent real-life performance.

WebXPRT 3 - OS WebView

The web tests showcase pretty much identical performance to the Mi MIX 2S which in turn both slightly outperform other S845 devices such as the Galaxy S9 and LG G7.

UI Fluidity

Over the past few months there’s been more outspoken discussions about Android speed tests versus actual device fluidity. In general the latter is extremely hard to quantize into a figure and there will always be corner cases or outliers that will probably perform better or worse when comparing between devices.

In the context of the OnePlus 6 as well as Snapdragon 845 devices I’ve looked more into what actually is different between them and what is seemingly causing the OP6 and MIX 2S to perform better than, say the Snapdragon Galaxy S9.  Looking deeper into the kernel it looks like OnePlus and Xiaomi are both using a newer kernel build with more scheduler modifications than the kernels running on the S9 and G7. The details here go quite low level and is out of the scope of any public article, but the effects can be easily seen.

OnePlus 6 vs Galaxy S9+ (S845) Jitter Test

In the UIBench Jitter test we see the difference between the OnePlus 6 and the Galaxy S9 – the latter has a lore more inconsistent rendering frame-times. While in this test both have very clearly great frame-times well under 16.6ms – having more consistent frame times in turn can avoid random workload events that might push frame times over the deadline and result in dropped frames. The OnePlus 6 so far has been the best device in this particular test – only the Pixel phones come near to it but they don’t seem to have the same consistency over time.

Overall system performance of the OnePlus 6 deserves the same praise as the MIX 2S – both devices are currently the very best and fastest on the market and you will be absolutely not disappointed in their performances.

    Just wanna know... Did you even read the article or did you skip right to the comments?
    I'm pretty sure the author has addressed your concerns already. And I've yet to see you providing a convincing counterargument. Reading the article isn't that hard is it?

    I'm entitled to have a different opinion, and the the writer addressed the notch "problem" wasn't satisfying for me, I'm of the opinion that most phone manufacturers are just copying Apple nothing else, and copying the worst design choices from Apple and not the good/great ones. Reply

    Well, other than your subjective aesthetical opinion, reasonably, notch just makes sense. If status icons are moved there, that means you can get an extra line of text on the screen.
    Like, one extra email, or a message, or whatever.

    I too also hate how it looks normally, but honestly, with OLED screen, it's barely noticeable, and I do appreciate extra space. I've come around :)

    The fact that apple was first is could just be dependent on only 2 things:
    - Samsung did not want to do it
    - nobody else has scale and numbers to custom order OLED manufacturers to make special equipment to cut up their screens.

    S9/S9+ might be better phones no doubt, but they're not "nearly the same price". Reply

    Where I live, in Europe, they certainly are. It's 20€ more for S9. Reply

    I don't see how a notch could possibly make a phone useless. They aren't appealing to me, but it seems like the rejection of the notch is based more in a dislike of Apple than a concern about functionality in a lot of cases. Reply

    The notch rejection comes purely from the hipsters. Reply

    I'm not even sure exactly what traits make someone a hipster or not, but I think people that object to notches represent a fairly broad set of demographics. Reply

    I don't think there are really that many people who care about notches. But if there are, all they need to do is refuse to buy phones that have them and suddenly alternatives will appear. Reply

    I'm definitely as far from a hipster as you can get and I'm also definitely anti-notch. Unless being so anti hipster is the new hipster? Never mind, I don't want to know.

    I'm also vehemently anti on-screen buttons and want my dedicated buttons back. I don't get this new screen form factor, it doesn't help anything and removes things I value.

    I have a OP5 (not T). I like it. It's the last of the honest phones. I do miss IR blasters being in phones as well.

    The Note4 was honestly the last great perfect phone. I went back and tried to use my old one and unfortunately it is just too slow. The new versions are over priced, and over Samsung'd. (That is to say, they're too locked down now.)
