CPU Overclocking Efficiency - Samsung Galaxy Nexus

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_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 .

Quadrant scores

So guys whats the max quadrant score you can get on your galaxy S?
Nexus S with almost same specs as SGS , overclocked to 1.4ghz can get 6k!

Doesnt really matter for me... but i stilll get 1400+ with jvt without any lagfixes or overclocks...
Wow
I only arond 1600 with MIUI

4000+ with tornado kernel
With tornado i got 39xx and thats without OC, just lagfix

All this Quadrant mumbo jumbo kinda makes me remember back in the days, when people where buying videocards based on 3d Marks scores... So the makers descided to optimise their drivers for 3DMarks instead of optimising them for gaming... So you'd get huuuuge scores on 3DMarks but crap on gaming (which is the primary reason for the cards)
nightly 7,1 kernel standard, oc 1300 and results 2100
Forget quadrant people, with just a simple ram script every device can easily get 5000+..

i just looked at the results on AnTuTu Benchmark... and some peeps are getting 7808 over-clocked to 1600MHz >.< how the hell can that happen!
Im getting 3756 on stock KI3 rom.
With F1 V11 ROM my score is 2750-2900 ...
3221 for me on Quadrant
I think it is not too bad...
3100 without Overclock with rom in signature. the phone is in the same conditions like every day, no stupid ram tweak just for quadrant
4360 with Tornado Neutrino @1440
SGS 9000B (ISDB Tuner) with the mod at my signature OC 1,4ghz and ext4 conversion.
Voodoo based kernel.

I believe nexus s can get that much score as it has a better gpu, whereas I get 4000+on semaphore kernel at 1300mhz on doctorz rom.
Nexus s is a better device. Its more open.
Quad. Doesnt matter a lot, u install some tweaks and they jump 500 in quad.

SetCPU profiles?

Hello all... I'm new to Setcpu and have been able figure out how to OC and UV while still keeping everything relatively stable. As of now I'm experimenting with making profiles, I was wondering if someone could post a screen shoot of their profiles and pass on any advice. I am running TNZ Blend 2.6.2 with the Hitman kernel. Here's a screen shot of what I have so far.

The only thing I would comment on is your "screen off" there is no reason for it to be scaling/jumping from 800-1200 "ondemand" while the phone is not being used or the screen is off in general, just have 800 low and high or have 800 as your high and set it to "performance" so that there is no polling being done and it will set itself to the high value which would still be 800 anyway.
You might have a reason for that setting, just trying to save you a little bit more of battery juice.
Definitely bring down that screen off! I have mine set to 200-500 ondemand. I'm sure it'll save you a lot of battery. Also the battery 100% is kinda pointless because that's what the main profile is for. And expect your phone to get extremely hot if you use it while charging since you have it overclocked. I did that same mistake now I keep it at 200-800 to avoid the over heating.

Just a recommendation...you should give tegrak a go. I find it to be much more beneficial than setcpu...
Why scale cpu depending on the battery level? I prefer scaling CPU on my phone by the temperature. 1.6Ghz normal usage and then gradually scale it down if it gets too hot. I bought this phone for its performance, not battery life, which actually is pretty amazing for such powerful device.

be careful with Tegrak, as it doesn't work with some of the non stock kernels, and will freeze your phone for sure..
Pretty good. You don't need the battery>100% profile. Adjust that from the main page.

Yikes! I wasn't aware of that. Guess I'll do a bit more research on that before I fire out recommendations. Note to self...not all devices have the same setup as yours

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.

[Q] Quadrant Standard Edition rating scores

Hi everyone,
Apologies if this is a rehashed question (My thread is two fold... Also to put up my post count!) But I was wondering what kind of 'weight' we can put on a Quadrant score? Is it really a reflection of how good and how fast our smartphone is?
I've used it in the past in trying to determine the best combination between ROM + kernel + OC app, but today by far, I've hit the most I've ever seen on my N7105.
Basically, DN3 v4 (BETA) + AGNi v4.2.1 R3 + 1.9Ghz OC (via AGNi tweaks) = 9211 on quadrant.
I was so happy!
I'm just interested to see what people think about the quadrant rating anyways, and what scores you've achieved.
They dont by any mean reflect the smoothness of the device, this test tests the power of CPU, GPU and ram of the phone. U might have a smooth device and low score and maybe the opposite.
Btw 20K stock

Nice score! I have a friend who said that the Note 3 is a touch over 21st stock as well.
All I know is that the DN3 ROM is butter smooth and my score definitely reflects how good the ROM is. (Quadrant on a stock Note 2 is 6400!) So I'll take those results any day!
Was just wondering how everyone else fared with their scores!

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.
