Overclocking? - Nexus 7 (2013) Q&A

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.

Which rom did you use?
Hi ABC Universal,
can you tell us how did you reach this score ???
The difference is so big...!!??
Looks like you're based on a chinese version as I see some chinese in the status bar.
Thx.
Really impressive!!!
How is it possible?

It is genuine output from quadrant running on defy. But yes there is no miracle performance boost.
Actually it demonstrated a limitation of defy's (and many others') CPU and a problem of quadrant benchmark. There is a detailed Chinese article explaning it but I understand only a little. Essentially, with some settings in android 2.2 system, defy (and many others) will fail the H264 decoding test, but quadrant takes it as completed in mini second, and thus the exceptional high cpu mark.
It was originated by some low end Chinese android phones which surprised people with exceptional quadrant benchmark. It turned out they had these settings enabled by default (/system/build.prop):
media.stagefright.enable-player=true
media.stagefright.enable-meta=true
media.stagefright.enable-scan=true
media.stagefright.enable-http=true
So this simply means the guys over at Aurora need to update their software to read the fail and drop the score to where it should be in reference to high end phones.
Does it mean that the Nexus and Evo 2.2+ scores are also wrong for the same reason?

According to the discussions, these two models enabled the settings by default. But I don't have them to examine myself.
That's explains why you install the sense rom, you obtain amazing Quadrant scores...
But really? no better performance? i thing this processor can do more than now...
not fake, i can do that too http://forum.xda-developers.com/showthread.php?t=976015
I think people getting 2700+ from defy now with this hack
hohoho, i go to try this....
EDIT.: For me, 1750 1Ghz 57vel
I've got 1231 @ 1000 mhz/53 vsel and 1303 @ 1100 mhz/55 vsel.
What benchmark app is this?
Whooooaaa!!! I don't believe it....!! Look awesome!
Down the line if the Defy can stay at average/consistant score around 1300 to 1500 should be more than enough running the daily apps/games available in the market.
Hit it more will eventually fried the poor Defy... huhuhu..!
mine got [email protected] on cm7 beta6, so you don't need to "cheat" to get a score that high out of the defy
this is my best score:
2617 on my defy with cm7 beta 6, cpu set to 1200 mhz and 80 vsel
but I think that there is something wrong: I usually get about 2200 (1950 with 1000 mhz, 1700 with 800 mhz), but every 5-6 tests i get similar score

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)

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.

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:

}
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

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 .

Wth 6000-8000 quadrant

Ok so I know quadrant isn't everything but please tell me why I have a stock att ogp with the lag of an optimus t? Did a factory reset and still the same thing. I let go of my HTC one for this device...I love it but what gives? Any help would be greatly appreciated! Thanks

When I first got my OGP I was getting 7-8000 on quadrant, but I certainly wasn't experiencing any OS lag. So if you happen to be from stock, there may be something especially wrong with your phone or there is something causing it issues. I originally had a corrupted SD Card on mine that caused some terrible lag issues for the day I did not know it was corrupted. Currently I nail 12,000s on my quadrant scores. I run the April factory OS without value pack, as the value pack seemed to cause some framerate slowdown in games and a lower quadrant score for me. My OS is de-bloated, and thermal mitigation is off (you can find this setting in your hidden menu). It helps to run Quadrant with a 60% brightness or lower starting the benchmark with a cold phone.
I have both the htc one and the OGP and my One scores a 2450 on geek bench 2 while my OGP hits 3000~. Granted my OGP is rooted and I use the performance governors but still they have identical SoC.
Do you have quad core optimizer on by chance? Also do you run this on a clean boot?
Yeah it's on but what I did was flash the telcel firmware and everything was just fine. It was like night and day! No stuttering or lag of any kind!

It's crazy though. Whenever I open quadrant, and look at system info it says my cpu speed max is 1728 but it runs at 1132 until I enable the thermal mitigation and it will read 1728. I'm on the telcel firmware and I can't find the High temperature property in the dial pad menu.

When I was stock, I ran an 11,5XX on quadrant. When I rooted and ran the stock ROM that's debloated and optimized I broke 12,000.
On my last two AOSP ROMs the phone feels so much lighter(os) but I only score down around d 8,000

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.
