I thought that nearly every android device that’s rooted can be overclocked using a custom kernel and app that allow it , but I found out that the poco f3 gpu can’t be overclocked and if so there is minimal improvement because of Qualcomm trust zone , I know that the sd870 is already an overclocked 865+ which in itself is an overclocked 865 and that overclocking produces more heat but I’m planning on doing a custom cooling solution for it , and I don’t even know about the cpu , I know that someone managed to overclock sd865 and beat 888 , so why isn’t it possible , is the problem with Qualcomm or Xiaomi , if it’s with Qualcomm what other mobile SOCs can be overclocked ? if it’s with Xiaomi what other devices even tablets that have sd 870 that can be overclocked ? Thank you !

when people talk about overclock, its mostly about the gpu.

The sd870's prime core of cpu is overclocked than that of the sd 865.

the gpu of the sd870 was locked by trust zone, so, it can be overclocked to a limit. (Max 683 MHz)

Some lucky guys have an unlocked sd870, where they can overclock their gpu and even reach 1000 MHz if they want.

sd865 was not locked by trust zone and thus can be overlocked up to 985 MHz

its not related to xiaomi

Keep in mind, if you do manage to overclock, it is best to have a cooler when reaching these overclock levels

So it is impossible to overclock the cpu of any mobile processor ?
is the sd865 the last processor that can be overclocked and wasn’t locked by trust zone ?
can you provide the link of the 1000 MHz gpu overclock ? Thank you !

The sd888 stock max gpu 840

According to this list it can be overclocked to 855, so, i suppose that means it is locked

You can undervolt at the same time. My 870 is unlocked. I overclocked it and undervolted. So I manage more power but with less heat and consumption.

Thanks a lot , do you think that 8 gen 1 water cooled will eliminate the heat problems and beat sd870 in prolonged gaming sessions

ofcourse but water cooling is overkill

there are mobile fan coolers that have a thermoelectric peltier that should do the trick but make sure that it has that peltier, a normal fan wouldnt cool well

sd888 locked is better than sd870 locked

sd888 unlocked is better than sd870 unlocked

sd870 unlocked is better than sd888 locked

same with 8gen1

The only reason a locked sd870 is better than 8gen1 in prolonged gaming is because the default clocks of the 8gen1 is higher than that of the sd870, so, more heat is generated.

Most phones will start throttling at 45°C battery temperature, so, the 8gen1 will reach that temperature faster than the sd870

Thank you so much for your help ! I think I’m going to opt for the 865 but I preferably want a tablet for gaming , and so far the only 2 tablets I found were : Huawei (it doesn’t have play store ) and Samsung tab s7 , can samsung devices even be overclocked?

i hate samsung, they keep complicating things with root and bootloader. The last samsung i had was android 7.0, so, i dont know much about samsung.

i recommend an 8gb or more ram, i have a 6gb and it is starting to be more than 80% used most of the time

if they both have the same specs then it is a personal preference whether you like a bigger screen or not
You can't root Huawei which is a killer for me.
What do you think the best smartphone brand is , in terms of overclocking and 120 fps support for games even if the phone doesn’t natively support 120 fps in all games , in which brand you can unlock the fps after rooting and overclock the 865 to 950 MHz ?

best brand in general is samsung but if you want to root and overclock, definitely dont choose samsung.

The only brands i have ever tried was samsung and xiaomi (Galaxy note 5 and xiaomi poco f3)

I know that Mi10T can be overclocked to 950, idk any other phones, im not well versed in this area.

When it comes to supporting 120 fps on all apps, as long as you are rooted, any phone will do, you can just change model name or use gltools
