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.

GFXBench Manhattan 3.1 Off-screen GFXBench T-Rex 2.7 Off-screen

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.

    More evidence to be used against LG when upgrading from my V30 when it breaks... Reply

    I currently use a V20 and feel exactly the same. Reply

    I have a V20 and the reason I never upgraded was no swappable batteries.

    for those whove never tried it, you should. you go from 5% to 100% in 1 minute. I carry no extra charging cable or charger, I slip an extra battery in my wallet and always have my screen brightness at 100%. never worried about battery draining.

    at home the phone is never connected to any cable. I simply charge the other battery in the cradle

    LG has massive issues with their phones imo. the g4 bootloop I went through. issues with the camera glass breaking on my v20 and aftermarket batteries dont work well as well.

    unfortunately im getting a 2nd v20 to have because of the swapping batteries. huge plus for me.

    For the life of me, I can't figure out why at least one phone manufacturer doesn't offer a decent phone with a removable battery. All the phone makers have decided that we want to throw away our phones after using them for 2 years, because the batteries no longer hold a decent charge.

    For the love of God, give us a phone that is designed to survive a drop or two. Making phones with glass backs, no bezels for protection and curved edges where the screen is higher than the bezel is insane. It really bothers me that this review had no evaluation of how well the LG G8 will survive a drop, but it spends so much time talking about its 0.6 mm increase in the thickness, as if anyone cares. The LG V20 was the last decent phone that LG made because it had a removable battery and was designed to survive normal drops.

    HTC, Motorola/Lenovo, LG and Sony are losing millions of dollars every quarter trying to sell phones, but none of them have figured out that maybe they should off something different, like a durable phone that is not based on planned obsolescence. The reviewers like Frumusanu would tell us how horrible it feels to hold a phone with a polycarbonate case, compared to a glass case, and how thick the bezels are, and how we simply can't live without IP68 rating, but those of us who care about the longevity and lasting value of our phones would buy it in droves.

    I have gotten so disgusted with the planned obsolescence in the phone industry and the monetization of my data and the collection of my data to train AIs, that I have decided to crowdfund the Purism Librem 5. I am willing to accept a lousy processor (NXP i.MX 8M), low screen resolution (720p), and a low camera quality, just to get a phone that is designed to last 5 years, protects my personal data, respects my digital rights and allows me to unlock the bootloader and install any operating system that I want (PureOS, Linux+KDE Plasma Mobile, UBports, LineageOS or PostmarketOS).

    Here is what a phone should have, but is is impossible to buy such a phone:
    1. Removable battery
    2. Plastic or metal case with thick enough bezels to protect the screen
    3. MicroSD slot
    4. 3.5 mm audio jack
    5. Dual front facing speakers
    6. Unlockable bootloader
    7. Designed to be opened using a Phillips screwdriver, so it can be repaired, not pried apart using a heat gun, suction cups and plastic spudgers, and I shouldn't have to reglue the f*ing thing.

    Maybe add an IR blaster ;). I love my v20. Reply

    LG and its crazy colors...I would feel disappointed the day their displays are not a disappointement. It always deliveries the lulz. Reply

    Non-flagship phone...
    Starting at $620...

    It should be a real pleasure to take that one up the financial backside. I hope LG includes some sort of lubricant with the higher end V50 since the price is likely in the $1K range given how they price out the supposedly more affordable G8. I did just buy an LG, but it was a refurb Rebel 3 from Tracfone for $10 - 5 inch screen, 2GB RAM, 16GB storage, removable battery (oddly absent from anything high end), and if it lives the next couple of years, I'll have sunk a total of $345 into two years of mobile service plus the cost of the handset (300 for airtime, 10 for the phone, 35 for a case, screen protector, and possibly a fresh battery after a year). It's balls out stupid to pay anything more than that for a phone when you could be tossing that money into some sort of interest bearing investment or workplace-funded retirement account so it can compound for you over the coming years. Every little bit makes a considerable difference over a long time horizon.

    poor americans. here in russia i have 100 Mbit landline, 400 min voice + unlim 4G on smartphone - all that for $5/month Reply

    Here in france, you can have unlimited voice/sms/rcs/mms & 60gigs of data (in 4g+/LTE) for just 9.99 bucks (or unlimited data for 15.99€ it depends). So when I look for google fi or other I just fell in apple so much that is expensive xD Reply

    Eh, there's nothing I can do to change the costs associated with living in the US. Reply
