GPU Performance

GPU and gaming performance of the G8 is something that is dictated by both the SoC as well as the phone's overall hardware design, specifically its thermal dissipation design.

We saw the Snapdragon 855 perform very well in the Galaxy S10, although the absolute improvements compared to the previous generation were quite conservative. Here the new LG G8 could distinguish itself by showcasing different thermal characteristics and possibly better sustained performance figures.

In the 3DMark Physics test which is mostly a CPU-bound workload within a GPU power constrained scenario, we indeed see the G8 performing better than the Galaxy S10+, which is a promising start. Huawei’s Kirin 980 phones here still lead the pack in terms of both peak as well as sustained performance.

The graphics test puts the G8 in line with the S10+ - both showcasing excellent performance. The Note9 still leads here due to Samsung having extremely lax thermal constraints on that device, resulting in quite high skin temperatures in long sustained scenarios.

In both Vulkan Aztec tests the G8 also leads the S10+ in the sustained performance department, even though the absolute improvements over last year’s G7 aren’t very big.

Finally, in Manhattan and T-Rex the G8 posts the most muted performance improvements over the G7, ending up almost identical sustained performance scores as last year’s phone. Here we also see the G8 tie with the Galaxy S10+.

Overall the GPU performance of the G8 and the Snapdragon 855 is very similar to that of the Galaxy S10+. The G8 is ahead of Samsung’s phone in some tests, which seems to be tied to more lax CPU thermal constraints. On other tests, the phone is pretty much in line with what we saw on the S10: conservative improvements over last year’s Snapdragon 845 phones such as the G7.

    How would I be out of my damn mind? The results are there, the display just isn't calibrated and isn't much of a step up from the G7. I suppose changing the display mode can remedy this, but of course for someone that isn't tech savvy, you would want the best out of your display, no?

    I guess what I meant to say its pitiful for not being accurate towards the color gamut. But dating back to my first G device, the G2, the IPS display was great.

    LG lost its imagination, we had very interesting phones from LG v10/20 G3/4/5/6, they had some problems but they had a "personality" and some good innovations, second screen, first with android 7.1, curved phone... Etc today they are just cheap ugly copies of Chinese phones, why copy the stupid useless notch while you had a more elegant and useful second screen?

    Their implementation of "second screen" basically means they invented the notch. That's reason enough to damn them, even if they did far it better than Apple and the current crop of imitations.

    So what has Samsung done to improve their design? It's the same curved display we have seen for the last few years.

    Thanks for the review! Do you think the schedutil governor could be responsible for the performance in Work 2.0? (Assuming the G8 still uses schedutil)

    One good thing about the recent LG V-series phones fro the US is that they support all T-Mobile bands. AFAIK only the Samsung S8 & S9 models do the same.

    So - the text says this takes micro-SD, but it's not in the specs list under 'storage'.

    "This is actually quite the competitive disadvantage for the G8, especially in the face of Samsung and Huawei’s newest triple-camera flagships."

    Why stop there? Compare everyone to Nokia's 5-camera spider-phone.

    To be fair the Nokia implementation of multiple cameras is just plain retarded.
  • BedfordTim - Wednesday, May 1, 2019 - link

    Nokia's implementation is designed to reduce the overall thickness which, while being pointless, it achieves. The trade off is that multiple small sensors don't collect any more light than one big one.

    I think where they have failed is in the software as camera to camera variations need to be overcome to properly combine the images and gain the benefit of the monochrome cameras.

    Well, I think the multi-camera trend is silly in general. Nokia's is just the silliest.
