Guys does anyone know if there is a way to control the Cpu / Gpu throttling on the Xperia SP on stock rooted roms?
XSP still needs development since its a new phone
Try doomlord's kernel if your looking to overclock your cpu. cant tell about gpu as i havent been able to get its setting through overclocking apps..hopefully upcoming months are gonna bring better kernels n mods

I don't want to overclock the CPU or GPU.
what i wanted was to set the temperature at which the CPU throttles the GPU and CPU,
as I noticed it throttles them way to early and causes performance to drop,
i've found a bunch of files in system/etc ...
thermald.conf
thermald-8960.conf
thermald-8960ab.conf
which most likely have the temperatures set in them, just dunno if they are degrees C or farenheit and it isn't clear which refers to which cpu speed either,
was hoping someone can help me out here ...
regards
Hello there, Ive decided to “overclock” my Snapdragon 888 iGPU. Im using the GPU pretty heavily with emulators like the new AetherSX2 and wanted to give this a try. My problem was the lack of performance with Lineage OS, Kernel seems to clock lower on default. So, this was the best solution for me.
If your Mi11 or other device with SD888 (other chips are supported too) is rooted, you could test this too and could share your results . I will be more focused on my results, here is a good guide with good values to start (table: OC#1 XDA), at the bottom of this thread: https://forum.xda-developers.com/t/...s-gpu-now-with-root-and-konabess-app.4275089/
What you need: https://github.com/libxzr/KonaBess, this apk allows to give your voltage value (fixed) a frequency. Set the frequency higher with const. voltage = overclocking, set voltage lower with const. frequency = undervolting. You should (please!) make a backup of your vendor_boot.img and save it on your PC, to reset to the default values if your phone isnt stable.
If my theory is true with lower voltage/lower frequency in this kernel, I basically have an undervolted iGPU with nearly the same performance of an SD888. After 20min stress testing in 3D mark or combined with Antutu there is still no thermal throttling. Somehow there should be a reason for the better battery life. So, a higher clockspeeds (nearly stock) with the lower discrete voltages should give a performance boost without sacrificing battery life.
Please be aware that my values could only work for AOSP or LineageOS 18.1 20211105, you should try it with little steps:

}
My results Antutu and 3d Mark:
It seems that the temperature and the stability is much better, than the stock MIUI Version, as you can see in this video
. Its a comparison between Mi11, S21 Ultra and Mate40Pro with 3D Mark Wild Life Stress Test. Peak performance on the Mi11 is about 5 percent higher, but at the end more than 25% lower due to the thermal throttling. Geekbench shows nearly no difference, it seems that it is more CPU-biased . Would love to hear the reason of all of this, please feel free to share your thoughts. Sorry for grammar or spelling mistakes, English is not my native language.
Hi
I have Xiaomi Mi 10T with Snapdragon 865 with Adreno 650 GPU and 8 GB LPDDR5 RAM and I used Konabess app to Overclock GPU to beat ROG Phone 5 in Vulkan performance.
I used This two tables to overclock to 905-940Mhz.
Adreno 660 is just overclock on Adreno 650 from Snapdragon 865.
If you want more performance look for CAF ROMs like I did.
I'm using Xdroid ROM with is CAF ROM.( CAF stands for the CodeAurora Forum. It is like the name says, an online forum (just like XDA, except, the forum is more for OS developers than flashmaniacs) where Qualcomm releases source codes and patches for their CPUs. Code Aurora is a kind of an initiative in which brands can release the open-source codes for SoCs(CPUs) for future software development. )
First few technical staff.
1000 Gigaflops = 1 Teraflops/TFLOPS
Adreno 650 on 587 MHz has 1202 Gigaflops
Adreno 660 on 840 MHz has 1702 Gigaflops
Adreno 650 on 905 MHz has 1853 Gigaflops
Adreno 650 on 940 MHz has 1925 Gigaflops
You overclock Adreno 660 to 855 MHz so you have 1751 Gigaflops.
You can calculate this very easily
Shading units 512 * freq 0.905 * 4 = 1853 Gigaflops = 1.8 TFLOPS
Compere to home consoles last gen
PS4 has 1.84 TFLOPS
Xbox One S 1.4 TFLOPS
Nintendo switch 1TFLOPS docked and undock around 500 Teraflops.
I overclock my Adreno 650 to 940Mhz giving me performance of SD888 with new drivers OpenGL 604 ( I link below if you want try on SD888 )
Ybf
Performance is incredible just from driver it self. Stock freq 587 MHz gives 4230-4150 score in Wild life just like SD870.
I used 940MHz and 905MHz on TURBO_L0 Voltage.
You can click on any images to get closer view.
Here is AnTuTu before overclock on stock freq 587MHz and 3Dmark Wild life
Now here we go to 940Mhz overclock with GPU.
AnTuTu Score beats Mi 11 and few SD 888 smartphones.
Here is Wild life and Wild life stress test.
Here are bonus 3DMark Sling **** Extreme Unlimited and Geekbench 5 Vulkan Compute test
And here are temp of Red Magic 6 series phones.
And here is temperature of all big SD888 phones to compere.
Here is test which show how many Watts GPU uses.
Overclock to 905-940Mhz with new drivers v604 use 7W on of power without idle screen 0.8W compere to SD888 which is much higher around 1.5W
Gfx Benchmark Manhattan 3.1 off screen 112-115fps with 7W
SD888 GfxBench Manhattan 3.1 off screen 117 fps with 8W-8.5W of power.
Running Genshin Impact on 60fps highest gets 7.2W of power with 58fps almost lock and SD888 uses 8.5-11W to run this game.

Thank you very much, gives much insight. Also it shows the efficiency of the 888, which is actually really bad for a newer gen cpu . Hopefully the competition with Mediateks Dimensity will push the development. 8 gen 1 seems like a disappointment, it probably will throttle like hell.

No Root support Custom MIUI / AOSP actually for Mediatek CPU... So for a lot of people Mediatek = No Way (like Mi 11T...)

Root is supported on any device of Xiaomi just unlock bootloader via Mi Unclock tool and get boot.img of your Rom you can do that even of MIUI without PC or find MIUI version for phone in internet.
When you update phone or you can select to install update again in right corner option you will get zip or your Rom just use rar and extract boot.img and repack it via Magisk app with unlock bootloader you can boot to fastboot and with adb debugging via adb flash boot.img from Magisk and you are rooted.

Maybe he meant the Konabess support, I think there isn't any way to overclock/undervolt a Mediatek CPU.

Yes I think there isn't but Mediatek chips have agresive thermal management so temperature is never high as exynos or Qualcomm

...hum i know that, i'm an active / old Xda users, and root my device from my first Android device in 2010.
When i talk about root it's for rom dev.
I mean Mediatek is not supported by dev... not more, not less. Mediatek is a pity for customers search waiting Custom MIUI or AOSP rom because any dev purpose build on this models.
And i think it's more important for users to have a CPU with a good compatibility with apps/dev/emulation instead choose a Mediatek for a "maybe" better overclock.

I don't know what emulator do you use but there isn't anything on the market with works better with ****s Mali GPU.
Emutation will be always Better for Adreno GPU than Mali GPU because it is incomplete it therms of GPU components and extensions of drivers.

Emulation do not depend only GPU but also CPU... Look like Exynos Samsung problem with emulator like dolphin

Im sorry, but I didn't make a backup of the custom values. It is easier to copy paste the values and probably better to tweak in little steps.
Can you undervolt though leave CPU frequency the same? With less volts though same speeds you should see better performance sure to less thermal throttling. Assuming it can run stable

Yes, you give your core other values. I basically give higher clocks at the same voltage values. But I've tested also lower voltage values at the same clocks and it works. But I don't know how much a increment is in volt. With LineageOS my phone runs already cooler, so I didn't feel the need to undervolt it.
I have successfully modified the default highest clock 840MHz down to 825 with one step down in voltage level (TURBO_L1 to TURBO_L0) and added extra lower clock 251MHz at the same voltage of the default lowest clock LOW_SVS
been using it for few days on pixel experience 12.1 with no issues, just a subtle decrease in gpu score in benchmark..but battery wise I didn't notice any difference
Now if anyone can share a way to edit the CPU voltage without applying custom kernels

What Turbo_L0 ! What the bloody hell ? What you doing?
855MHz NOM_L2
840MHz NOM - NOM_L1 -NOM_L2
830MHz NOM and lower.
...
257MHz Retention fyi ,
Red more about undervolt it must on SD888.

As far as I know 840MHz @Turbo_L1 is the default max clock of adreno 660 which also was the default value in konabess
I only undervolted it once by going one step down in voltage because frankly I don't want the hassle of trial and error..but if you are saying you could boot with even lower voltage with nearly same performance I might give it a try

Not could it works perfectly tested on few hundred devices.
Of course your silicone lottery can be different but -10MHz is worth it to use with NOM aka 830MHz and lower.
