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.

    Think the Sony Xperia 1 II is a much more rounded device. Flat 4k screen, 1/1.7" camera sensor, stereo front-facing speakers, SD expansion, 3.5mm headphone jack, no notches or holes, nice build with niceone-handed use, clean software. Reply

    For the OnePlus 8 which starts at $/€699, there’s actually very little competition out there at this price range"
    Don't know why you compare it with the S20. The competition are other non pro flagships.
    Mi10, P40, ...

    Watching the trends in the mobile industry has convinced me to preorder the Purism Librem 5, because it fights all the things that the mobile industry does wrong. Why hasn't Anandtech covered Linux phones? Look at the features of the Librem 5: an SoC manufactured for 10 years, a removable battery, replaceable cellular modem, replaceable WiFi/BT, lifetime software updates, smartcard reader for OpenPGP card, free/open schematics, headphone jack, convergence as a PC.

    "no 3.5mm jack"

    Someone needs to tell them Xiaomi is making SD865 phones at the $500 mark, and they have both a headphone jack and an SD card. I am still using a Galaxy S9 (Exynos, EU), but was dismayed to see my wife's new Xiaomi Note 8 Pro (Mediatek 90T) is much, much faster than my S9, which cost almost 1K€ back when I got it at release.

    Can the 5G modem be turned off / disabled through Settings for those who wish to stick to 4G? Reply

    Did I miss it somewhere or was the OS covered? More specifically, does the 1+ come with the minimalist OS it used to? I dislike all the bloat from other makers. Appreciated the lack of with 1+ products. Reply

    Nice review. But you guys should add audio review also. Especially review of loud speaker of the phone Reply

    Which model of the 8pro was used for these tests? I did look for it but it doesn't say if it was the 8 or 12 gb version. Not sure if/how much that would alter results... but it would be nice to record that. Reply

    I also noticed that in some other comparisons you used the 3dMark extreme slingshot test but not for this one. I have found my 8pro performs that test ~15% better than iPhones. It would be good to include a test where it performs better than iphones for the sake of fairness/completeness. Reply
