CPU Overclocking Efficiency

Recently I've decided to overclock CPU and evaluate efficiency in term of speed by using one of the famous and best FRANCO KERNEL.
So I've captured 1 minute 1080p raw video with stock settings (no mods or hacks to mediaprofile.xml file) and rendered file in Google Movie Studio in 1920x1080 aka 1080p format and High quality.
Consequently, the results were as follows:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
As you can see the most efficient OC frequency is 1305Mhz. All above are way slower, cause CPU gets hotter and efficiency decreases.
Yes, do admit overall smoothness is by far better in comparison to stock kernel, but as you can see overall efficiency is not a deal breaker.

Maybe try the version with the overclocked gpu. I think this can have a big impact, I mean on the PC most of the work is done by the gpu so I could be that it's similar on our phones

First look and then write... Franco has a 512mhz version because 384 ist his stock

it's said that the difference is so minuscule, the 512mhzoverclock isn't worth battery loss. I'm not talking about relative to Franco, the device's stock gpu frequency is 304. But if you see it that way, to each his own.

Unless the GPU has built-in hardware encoding or decoding for the particular codecs involved, and it's actually being used by the software, it won't play any part in video rendering.

Interesting.You could try the same with Trinity .

[Q] overheating or not?

Hi guys,
I have tested my HTC One X and I came up with these results:
CPU on max load:

"lightbox_close": "Close",
"lightbox_next": "Next",

}
CPU on standby:
Battery on max load:
Battery on standby:
Ones I lost my network and I had to restart my phone.
Are those temps on max load too hot and what is the max safe temp?

Is it possible that no one can tell me if those temps on max load are too hot and what is the max safe temp
Anyone to share their temps at least?

82C in your first screen capture is too high (if the reading is correct). What app are you using?

System Tuner from 3c with Stock Kernel. Default values not overclocked CPU neither GPU.

82 is ok for cpu It's the battery you wont to wotch that shouldn't Ho above 50

I'm not really good in terms of software/coding but I know a thing or two for hardware, basically an 82ºC reading for a mobile processor is way past over its limit(around 54~65ºC). It's just way too high add the variable of poor ventilation and crammed hardware, what OP should worry about is the actual health of the phone as a whole.

Ok I may be wrong but I am shure I have read a few times around this forum 90 is ok Just wotch the battery temps and iv been reading a lot in the past two month some sort of addiction lol

Thanks for answers!
I have found something interesting:
Tegra3 is a quad core 1.5ghz 40nm SOC and so learn to accept its operational temperatures i.e: 45c Battery and 75c CPU during heavy use

and here is the link:

Here si my two videos of gameplay on HTC One X JellyBean Sense 4+ (maXimus v4.2) and temperatures of CPU and Battery:
Shadowgun The Leftover
After 12 minutes of play with pluged charger
CPU temp: 61 C
Batt temp: 46.3 C
Dead Trigger
After 12 minutes of play
CPU temp: 65 C
Batt temp: 47.0 C
If the reading are right, those temps are far more better on JB and Sense 4+.

Overclocking?

Considering how the S4 Pro in the Nexus 7 is actually just a downclocked version of the Snapdragon 600 I presume there is a decent amount of wiggle room for overclocking. Yes, these are probably the worse chips out of the binning process to have been condemned to live the rest of their lives as S4 Pros, but would hope all of these should easily be able to achieve the 1.7Ghz Snapdragon 600 specs. Maybe even some lucky owners could push theirs to and beyond what we see in the Galaxy S4 at 1.9Ghz.
Now I'm just speculating as my Nexus 7 isn't even here yet (still in shipping). I made this post to make some discussion on the matter. Like people who've already tried messing with clock speeds and voltages on theirs could share their findings here. Talk about what kernels permit what levels of tweaking. Or even GPU overclocking/governor tweaking etc...
So, discuss!

I've tried running it over 2.1 Ghz with no problems at all. I really just wanted to see what a benchmark could get up to. I didn't check the voltages were. I tried running it fairly hard and of seemed to do alright.

What's the score of the benchmark you got? Is it almost the same as S600 devices?

I was able to atget up to 8849 on quadrant. It is consistently above 8000 for me using CyanogenMod and an overclocked kernel at 2052 Mhz CPU and 487 MHz GPU. At 2052mhz it is at 1175mV.
Edit: I got a slightly better score again

It seems the the score of the benchmark are the same with Xperia Z stock with S4 Pro.

Running at 1728mhz for days now, GPU at 487, handles perfectly fine.

CPU speed for Snapdragon 808 1.44GHz?

So today got my replacement new G4. Dowloaded the CPU Z app and it shows my cpu at 1.44. But my benchmarks in antutu are fine.

Or are you serious?

Can someone check theirs and see hat it says? I think i know whats going on. The two cores 4 and 5 are the 1.8GHz and 0-3 are the slower cores.

It's hard to catch 4 & 5 doing much of anything, so I launched a huge game that takes some time to load, switched back to CPU-Z, and snapped a quick screenshot. The apps just report the max CPU frequency incorrectly. They probably just need to be updated for the 808.

That's because you aren't doing anything....
Take your thumb and scroll up and down fast and you'll see it go up.

My thumb wasn't fast enough to get 4 & 5 above 1.4 GHz while taking a screenshot. Launching a big app was a lot easier. Obviously 4 & 5 do move some, but the concern was that they were capped at 1.4 GHz since all of the apps show that as the max CPU frequency.

It's the governor and cpu control that does this - it regulates speed for temperature and battery control by changing the value in sys file system, so cpu monitors that read that once and treat it static will always get a false value.

Here are couple of screenshots showing the 2 high power cores 4&5 at their maximum speed of 1.82GHz. As well as their speed history.
I used System Tuner app from the Play Store. You don't need root to use the app to monitor system usage.

Processor speed

Hi Guys
Has anyone checked the frequency the cores run at yet? Mine doesn't seem to go above 1.59 Ghz (checked using Better Battery Stats and CPU X). Antutu score was also low. Something doesn't seem right here.
OK, scratch that. I used the Quallcom Trepn app and that showed the cores firing up to 2.2. Still don't know why Antutu is low (113000)

Hi.
Try enable max CPU in developer options. ( or something like that ).
I did , mine jumped from 113000 to 136000.

I'm having the same issue with my Antitu score. The funny thing is, I get a higher score with performance mode turned off!

Heat Problem.
The phone throttles down.
Put it Into the fridge if you want a higher number.

It would most definitely eat up more battery. It's good for running (relatively useless) benchmarks, but certainly not meant for everyday use.
