Exynos990 GPU is not even half as powerful as SD865 after 20 mins of sustained load - Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News

Exynos990 GPU throttles so hard that it's not even half as powerful as SD865 after 20 mins of sustained load

Another reason for not to buy Exynos soc version.

It performs worse on everything, including the camera!

Quick system info

Anyone notice in the quick system info the processor says armv7 processor 662mhz. I assume that's just an error and its really 1ghz right?
I believe the phone has something similar to Intel's Speedstep. At idle the processor speed drops way down and it only increases as far as necessary so as to save power.
The CPU is automatically scaled as demand/load increases. 1ghz is the max when under heavier load, so it's to be expected that it would be running at 662mhz when you bring up system info. Don't worry... that's normal.
well i refreshed it like 20 times, I even see it hit 162mhz
how about free memory? I had a ton of apps open it said 20mb free is that normal?
BogoMIPS is NOT the same as MHz on the Nexus!
Multiply that 662 by 1.507!
ohh ok lol

solution for being to hot when playing games

So we've all known that this overheating is caused by CPU. I tried this overclocking widget, setup maximum cpu frequency as 800MHZ and minimum 500MHZ and tried playing games again. battleheart 30 mins and didn't get heat up any more. besides the power draining problem seemed to be less noticeable.
I read the CPU is an overclocked 1ghz which would explain the high heat when playing games. I personally have mine clocked at 800mhz using SetCPU at all times and it no longer gets very hot.
will give this a go...fed up of burnt fingers lol
come back to report. just now played around 1 hour game, battleheart, with max cpu set 800MHZ, power went down from 65% to 41%, not too bad. guess I can play games at least 4 hours. most important thing is never feel the heat again.

It might have to do with having 8 cores in the system. The problem is that we do not have cooling on our phones BUT: per say you run a game that requires full power of the smaller 4-core processors, and we have 8 cores in total, the game will run evenly on all 8 (hence why you don't notice any lag even though it gets throttled) or maybe a little more towards the bigger 4-cores, they generate too much heat. It's better to spread the load with lower speeds than to keep it running on bigger cores (less cores also) at higher speeds. I believe you can modify your kernel settings to change the throttling temperature if the kernel supports it. I've went back to stock kernel because practically there was no difference when it comes to being a regular user. The cooler the processor is the better hardware life you'll have in the long run, after all, phones don't have sufficient cooling to support such processors at high frequency all the time.
If it throttles later on, let's say 70-ish, you'll complain that the phone heats up like the galaxy phones

[Q] What do you do against overheating/lag during gaming?

As we all know, the Snapdragon 810 processor in our OnePlus 2 phones is prone to overheat, especially during heavy tasks such as gaming. With the stock kernel (which probably most of you are using) this leads to the A57 cores being partially or fully shut down and the display - which generates additional heat - being dimmed in order for the phone to keep a healthy temperature (healthy for both its components and the hands that are holding it.) This, in turn, leads to lag when playing especially demanding games. Which in turn leads to a frustrated user.
With root access, it's possible to use custom kernels and/or custom thermal throttling profiles in order to (at least partially) circumvent these issues, by throttling the CPU frequency and/or limiting the number of active cores, using different schedulers and governors, and by applying thermal profiles that allow the phone to get hotter (in order to keep higher CPU frequencies for a longer duration).
Since I bought the OPT, I was playing a very power hungry game - Republique - which, at its highest graphics quality setting, pushes the phone to its limits. I quickly switched from the stock kernel to the Boeffla kernel and started experimenting with schedulers, governors, hotplugging settings, CPU/GPU frequencies and thermal profiles, but nothing I have done so far makes it possible to play the game for more than 15-20 minutes before some kind of throttling / heat control sets in and the game starts lagging.
I tried limiting both CPU clusters to only 2 cores while maintaining higher frequencies, I tried throttling the frequencies and keeping all 8 cores active, and I tried all kinds of solutions in-between with anything from 4-8 cores active and frequencies anywhere between 60% and 100%. I also tried the various thermal profiles that the kernel offers. But whatever I did, the game was either lagging right from the start, or running smoothly for about 15 minutes before the screen was dimmed and the CPU was throttled, leading to a laggy experience.
So my question is, what do you guys do to keep the OnePlus 2 from overheating during gaming, while at the same time maintaining a lag-free experience? I don't seem to get anywhere with anything I try, so I'd be extremely grateful for some useful input.

All the phones throttle while gaming. I use thermal extreme with boeffla kernel. And use 2 a53 at 1,3ghz and 2-4 a57 at 1,4ghz and I modified the throttle file and it underclock to 1,2ghz when it gets hot but it doesn't happen if you don't play longer than 30minutes and it doesn't lag either. You can leave stock settings but if course it will get hot quicker. Also with thermal hotplugged or something like that, I used it all cores online all the time at full speed and it doesn't throttle for a long time, so I don't know what overheating are you talking about. My nexus 5 throttle faster and disable 2 of 4 cores and leave the other 2 at half speed, and our processor overheats?. Oneplus throttle the device a lot because of the rumors, fortunately we can change that. Try what I said, cheers.

Thanks for the tip with thermal extreme! The implementation in the latest Boeffla kernel v1.1 beta1 seem to do a very good job of not letting the phone get too hot while at the same time not throttling the CPU too much. Today, the performance was stable for almost 30 minutes of gaming, and when I checked the CPU stats I saw that all cores were still active (2x A53 + 4x A57), and only throttled to 960 MHz. This still delivered enough performance. (I started the game with both CPU clusters at 1.2 GHz, so this also seemed to help with keeping the phone at an acceptable temperature. I'm sure it would've gotten much hotter much quicker at higher CPU frequencies.)
I have to admit though, I was playing inside in an unlit room and thus the screen wasn't at max. brightness. We'll see how it will perform during my next work break when I have to make the screen much brighter.

Does it throttle to 960mhz? for me never reach 1,2ghz. Playing real Racing for 30min it stays at 1,2ghz. And with thermal hotplugged (all cores enabled, all at stock freq gpu too) it doesnt throttle for 30 min, gpu only sometimes to 510mhz, i played 30 minutes and it didnt throttle, i dont know when it was going to throttle because i stop playing. But also, gaming with all cores and no throttling eats the battery.

I guess it throttled to 960 MHz because the game I'm currently playing (République) is pretty resource hungry.

Thermal Throttling on POCO F2 Pro

Looks like some POCO F2 Pro got thermal throttling.
It need to look like this: https://www.chinamobilemag.de/test/poco-f2-pro.html#hardware-performance (last picture - 15 min. test)
On some reviews I saw throttling after 7-8 min. so maybe you check your device and in case of throttling you replace your F2 Pro.
Summer but not too hot starting of with not cold but slightly warm phone.
Under all core synthetic load lower tier cores started throttling at 14min and the highest clock core still at full capacity.
Honestly anything over 5min mark on synthetic load is impressive without active cooling.
I don't see many things that would utilize so many threads with continuous load. I wonder if adding GPU load to the mix wouldn't have changed things. Then again it's not a gearvr kind of a thing with 60hz fullhd + screen do I wouldn't expect it to throttle under real world load.
And I must say both during use and fast charging poco f2 pro feels less hot than 9t pro did. Charges longer at high current before temp rises enough to slow down charging.
