GPU Performance

GPU performance of the new OnePlus 8 devices should be interesting as we finally have more Snapdragon 865 platforms at hand to test, beyond the initial Galaxy S20 scores that we were able to showcase a few months ago.

Basemark GPU 1.2 - Medium 1440p - Off-Screen / Blit

Starting off with BaseMark GPU 1.2, we’re seeing some very good results from both OnePlus 8 phones. Although peak performance is just a tad little bit lower than the Galaxy S20 Ultra, both OnePlus phones are able to showcase much better sustained performance figures with essentially no throttling after prolonged usage.

GFXBench Aztec Ruins - High - Vulkan/Metal - Off-screen GFXBench Aztec Ruins - Normal - Vulkan/Metal - Off-screen GFXBench Manhattan 3.1 Off-screen GFXBench T-Rex 2.7 Off-screen

The same characteristic of both OnePlus phones having essentially matched peak and sustained performance figures is essentially mimicked in all other GFXBench tests. Again, this comes at a contrast of our first impression of the Snapdragon 865 that we tested in the S20.

I’ve since then also been able to test the LG V60 and the Xiaomi Mi 10 Pro to have a wider repertoire of Snapdragon 865 phones and all of them seem to perform similarly to the OnePlus 8 and OnePlus 8 Pro, showcasing excellent sustained performance characteristics.

The OnePlus 8 phones had excellent thermal behaviour during the stress tests, with the phone never exceeding ~37-38°C peak skin temperatures which points out to fantastic heat dissipation from the SoC to the whole phone body.

These new test results finally give meaning to Qualcomm’s initial claims of excellent thermal behaviour of the new chipset and that it is able to indefinitely maintain its peak performance. Both OnePlus 8 phones are able to materialise this claim and will have no issues with providing excellent performance in games.

    Yup. People with expensive high-fidelity headphones want to be able to listen to their extensive, high-fidelity music catalogs on their expensive, high-fidelity flagship smartphone. I don't see what's so hard for designers/vendors to comprehend about this...

    Just because Apple decided to go full retard with deliberate omission of a headphone jack, doesn't mean the rest of the world has to voluntarily lobotomize itself in response. Even though it did, and continues to do so - it doesn't HAVE TO keep on doing it. Idiots....

    OnePlus8 pretty much makes the case that flagship killer is henceforth pointless. There is hardly any "need" that can only be possible on $1000+ phones for 99% of the usage cases. Since OnePlus7 Pro, the extra $300-500 tacked onto the flagship class phones are mostly for checklist and not utility. Rational consumer, i.e, the flagship killer demo, pay for need and not marketing. Reply

    Not a flagship at all when it lacks 3.5mm jack and no Micro SD slot. Esp with their proprietary bullshit charging and uber high speed, high current, high voltage battery destroying tech all for Samsung level of price with their bloated garbage Oxygen OS.

    And it's CCP powered. Only good thing about this phone is its Bootloader unlockability.

    "Not a flagship at all when it lacks 3.5mm jack and no Micro SD slot. Esp with their proprietary bullshit charging and uber high speed, high current, high voltage battery destroying tech all for Samsung level of price with their bloated garbage Oxygen OS."

    My question to you is whether you have used a OnePlus phone before to come to the conclusion that the Oxygen OS is garbage? I have not tested the OneOS from Samsung, but the Oxygen OS is leaps and bounds cleaner and smoother than the old TouchWiz OS from Samsung. Having used a OnePlus 7 Pro for some time, I feel the software support/updates from OnePlus is also better than Samsung. I am confident to say that Samsung probably included more bloatware than OnePlus, since OxygenOS is pretty much the closest to the stock Android experience.

    The lack of micro SD slot is a bummer, but 3.5mm jack is pretty much missing in most of the new flagship phones.

    Coming from a pixel 3 to the OnePlus 8 this phone is incredible but the camera is straight trash. Reply

    What's Samsung's secret sauce for the high CPU numbers on the SD865? Reply

    Too bad both the headphone jack and MicroSD slot are missing, making it totally irrelevant to me. "Never settle", right?

    Also bizarre that the reviewer says good riddance to a pop-up camera. Having a piece of the screen missing is a negative.

    Absolutely don't want these phones, I wouldn't use them even if they were free.

    It's funny OnePlus's mainstream model beats their high end "Pro" mode practicality wise. I almost never considered the "Pro" model. Reply

    After so many iterations, what does "flagship phone" even mean ?

    Does anyone even care anymore ?
    When you need a toothpick, do you go for base model or check the sites for a "flagship" one ?

    Thanks for the detailed review, from a new op8pro user.
    In your opinion, in terms of battery drain what the difference will be between 90hz and 120hz?
