[Q] Octa-core Samsung Galaxy S4 caught cheating on GPU benchmarks

Octa-core Samsung Galaxy S4 caught cheating on GPU benchmarks. The real GPU Clock is 480MHz. When using benchmark, the Galaxy S4 GPU start ticking at 532MHz and continues to do so until you exit the app.
So, my question is,
How can we overclock our GPU to 532Mhz?
Maybe the devs can make the GPU always 532Mhz on Custom Rom like Cyanogenmod Rom to get the best performance?

The real GPU clock is 544MHz.

I read the article somewhere (can't give you the link because I'm new user), the real GPU is 480MHz. It only clock to 544MHz when you're running Benchmark tool such as 'Antutu Benchmark'. But after you exit the benchmark app, The GPU will clock to 480Mhz for battery saving. It will never use 544Mhz unless you're running benchmark app.

WOW !! Really ? What Rom that u're using ? Can I use Perseus kernel and wanam lite rom ? or with cyanogenmod ? and how can I check if my GPU is clock at 640Mhz ?

I've flashed perseus kernel. I see that the GPU can be overclock to 700MHz.
Is there any problem/risk for my phone to damage if I overclock the GPU too much ? 700MHz ?

from my prespective, id'nt touch that ,since overclocking GPU eats up battery like crazy ,id only overclock it if need it for some big apps or games that lags on default gpu settings but i never had kinda issues so i just leave it on default..
Anyways, check http://forum.xda-developers.com/showthread.php?t=2356445

Mine @ 700MHz. Smooth as butter... :laugh:

[Q] disable Dvfs?

Tl;Dr is it possible to turn off Samsung's built in frequency adjusting/locking?
I was messing around with clock speeds just to see what affect it might have (it used to be helpful on my Note 2 to raise the min clock speed a step or 2 when I turned my screen on) and noticed some strange behavior.
It seems Samsung has built in some of this. Every time I turn on my screen most cpu apps will tell me the min clock is set to something like 1.9 ghz. The built in stuff overrides any settings I apply. Now, the main reason I'd like to change this is the Samsung stuff seems buggy (surprised? Psh...) and the min cpu frequency seems stuck at 1.9 ghz. If true, that can't be good for battery.
So, anyway to turn that stuff off? I imagine it would require a custom kernel and I should just give up.
Thanks
Apps tried:
ROM toolbox pro
No frills cpu control
Antutu cpu master
Other free apps

Gameloft games are only optimised for Adreno and Mali, not PowerVR.
GTA SA lags with almost all android devices

Man, but this game no lag in stock tw 4.3 and cm11 even i used only 2 core clocked in 1.200ghz.. maybe this bug only in i9500 tw 4.4.2 ?

Probably Samsung's aggressive thermal throttling which was introduced with 4.4.2.
BTW, how on earth did you get games to only run on 2 of the 4 low power A7 cores?

No, the A15s run at 1.6Ghz... which is what I am rather concerned about.
Because a normally functioning phone should utilise all cores and speeds should be fluctuating above 1.2Ghz in for graphically intensive games in your case.
The i9100 has a optimised Mali 400 GPU which should run GTA better than most Adreno or PowerVR of that gen.
It is also worth noting that the SGS2 is running at a awfully lot lower resolution at 800*480 compared to 1920*1080 which will require a lot more processing power than the S2 to run those games at similar settings.
Both GPU and CPU are important.

Ita possible disable cluster commands?

I just bought a s4 i9500 and I really hate the "s lag". I think disabling the cluster Qual Core A15, will lag free, something like trick the kernel to run always in light tasks and the power cores 1.6GHz wont activates ever. Dumb Question? yeah, maybe.
Edit: Using only Quadcore 1.2GHz will be efficient too.

yes,you can..with root and right kernel...but it'll kill the purpose for having quadcore chipset right?
i've been using for play games,it can last about 3 hours if i play directly.
there's no point to disable A15 because it wont activate if you run light task.

[TWEAK][DISCUSS][Z5/Z5c/Z5P] Improve/Turn max performance for S810 on Xperia

I intended to delete thermal engine to unlock the maximum performance of S810, but I didn't after a half day for thinking. Then I took a look at thermal-engine and do some optimize for it.
When I looked at the thermal-engine, I saw it use emmc_therm (temperature of emmc) sensor to do throttle, and the throttle start too soon, from 43°C, detail is two cores 6 and 7 will be hotplug (plug out, turn off), and big cluster will be limited to 1.2GHz at just 47.7°C (the battery temperature is just ~40-41°C). You can see more detail in below:

EXPLAIN (from my knowledge, maybe it's not right at all)
cluster0: LITTLE (A53 cores) cluster clock limitation, value: hertz
cluster1: big (A57 cores) cluster clock limitation, value: hertz
hotplug_4-7: 1 to hotplug (disable) the core, 0 to do nothing.
gpu: GPU frequency, value: hertz (?)
s_backlight: the maximum brightness of screen, range: 255-0
modem: 1 to disable mobile data, 0 to do nothing.
the rest: IDK
I did a quick research and found that emmc can work from -25°C to +85C, so the limitation that Sony has set is too low (for me), just do a Geekbench and then the performance will come down clearly. Then I edit thermal-engine to increase the maximum performance of S810 but still keep my phone (IDK about yours just because we're not the same) in peace.
So why do I post here? Firstly, for those who wanna take the risk like me to unlock/get the true performance of our devices; secondly, maybe my knowledge is not right so I want you who have certain knowledge about this (EMMC, battery limitation; thermal, blah blah blah) correct me and help me and other users improve it.
I've done attached two files, one is original and the other is mine, hope you guys (who are sensei) will take a look on it to contribute for the community. For those who wanna use them, backup thermal-engine.conf first in /system/etc then copy the modify to the direction, correct name and permission and reboot.
UPDATE:
Thanks to @Envious_Data, his guide helped me to manage big cluster, now I can turn 4 big cores always on by make them becomes "non big cores", so now our phones are true octa cores. I was afraid that there're some issues that will appear such as heating, throttle (thermal manage won't work correct if it recognizes big cluster to be little cluster) so I made a test with Antutu Stress test and monitor CPU cores via Trepn Profiler, and amazing, thermel engine still works fine and my phone's temperature isn't different from old/original settings (just 1 big core on time and will be plugged in if need) so far (of course it should be hotter but not much). And I updated new thermal values too to improve some performance in camera. About battery life, I guess it would not go so far from stock settings because I saw the current discharge (mA) isn't higher (a lot).
Update 17/06: re-setting back to big cores for the best compatibility after enable all 4 big cores, so true octa cores is still there with big core setting is 1 (true).
Update 23/06: new thermal-engine to adapt with OC from SunKernel, it still works fine with stock or even any different maximum clock speed in kernel, why? Because I simply just remove "clusterX" action instead of edit it to match with the maximum clock.
INSTALL: download MODIFY files and rename to init.qcom.post_boot.sh and thermal-engine.conf (due to XDA's restriction so I have to change their type), put in /system/etc/, correct permission (644 rw-r--r--) and reboot.
UPDATING... (depend on you)

Now i try your file, my phone give 89k in antutu constantly

You tweaked it to 63°c max? Sounds not bad at all..

Actually you can see the emmc_0 and emmc_1 so the maximum is 68 Celcius and start throttle from 52.4 Celcius, at that temperature of emmc I still don't notice hot in my hand.

What kernel are you using? I've just got reboot when do Antutu bench, two times.

Androplus v30 with stock setting governor and clock speed

I have almost 84k on stock kernel. Nice

I've used this for some days now.
Was in Turkey last week (30°c) and all was fine.
In fact, performance seems much better.
I don't use benchmarks at all but I can feel multitasking is faster for a longer time and so for camera applications.
I'm now using it on 224 fw and Andro-kernel v31 and all seems good so far.
Thank you!

U can set it via sysfs path in init.d or su.d script, depending on what kernel u use (different paths)
Note that especially for heavy tasks u will notice performance drop when disabling these cores.
I disables two big cores and for light use it was okay but the camera app started to lag.

Thanks TS. Works pretty well so far for me (.224), and indeed the phone feels faster and more reactive under heavy load (noticed it after I finished recording a 10m 1080p60fps video). Good job
