hi guys i just want to know what is the max overclock of the cpu and the gpu for the nexus 7 ( please has to be has safe as possible, i dont want to damage the tablet too much, and yes i know that overcloking will reduce the life of the tablet) I want to get the best performance out of this tablet!!!!!
Note: battery drain is not a problem!!! I will use the nexus 7 for gaming most of the time and also browsing!!!
Please I really want to know i created an account on this site for this!!!
Most people can go to 1600 on the CPU. Any real world performance increase from the stock 1300 is negligible.
I wouldn't overclock the GPU past 446 (+30) because anything higher creates a lot of heat and people have reported benchmarks actually being lower once you go much higher than that.

Hi, tbh you'll probably not notice much if you overclock the cpu to 1.6ghz as percentage wise it isn't a large jump. Things may feel a little zippy at times though, in my house I have acces to two n7's, one stock and one overclockable to 1.6ghz. Ran tests between them and the 1.6ghz was fractionally faster, the difference was very small. Overclocking the gpu to 600mhz vs 416mhz at stock made a huge difference, as it it made some games actually playable. Despite the crap Nivida spit out about the tega 3 soc, it's GPU is comparatively weak. Over-clocking the GPU will give immediate performance increase in a lot of games. After doing heat and clock speed tests myself, I've found anything in-between 416-600mhz to give near enough liner performance increase and heat to be long term sustainable depending on the voltages your device can handle. Overall, I doubt CPU overclocking will give you much benifit, but if you play games the gpu overclock will. If your worried about heat from overclocking the gpu a lot, you can always use this kernel http://forum.xda-developers.com/showthread.php?t=1937146, which gives you full GPU clock and voltage control so you can undervolt your gpu to reduce heat. I wouldn't run at 600mhz unless I could undervolt the gpu as much as I have and I use that kernel because of it. I have my gpu overclocked to 600mhz running at 1225mV, which is only +25mV above stock voltage for 416mhz. Although most heat is generated from the transition period of the transistor charging/ discharging, undervoting does give a large positive effect on heat output if it's large enough. But 600mhz is a high GPU clock and the highest I'd recommend, tbh I would say 520mhz is a really good compromise between heat, performance and battery, especially if you under-volt the GPU at that frequency for most people if your not as annal with FPS as I am :silly:

AW: Nexus 7 Overcloking
You all probably have seen those 2GHz oc screenshots.Are those real?I'm not wanting to try this I'm just curious.
Sent from my Nexus 7 using xda premium
They are probably real
yes i have almost sure they are real, but puting the nexus 7 in 2Ghz will, i think will damage a lot the tablet!!!
The 2 GHz kernel was a test to see how far the Nexus 7 could be pushed. This kernel wasn't released for obvious reasons so yes, those pics/ benchmarks were true.
Post on Gsmarena:
"The motherboard has a Qualcomm Snapdragon S4 APQ8064-1AA chipset, which as it turns out is a downclocked Snapdragon 600 chipset – four Krait 300 cores (rather than Krait 200) at 1.5Ghz and Adreno 320. There are also four Elpida 512MB RAM chips, SK Hynix 16GB eMMC storage, a Wi-Fi a/b/g/b and BT4.0 capable Qualcomm chip and an Analogix SlimPort transmitter."
PS: Sorry if this piece of info was clarified somewhere else in the forums, I did not found it.
Yes it is a downclocked s600 which comes with krait 300 and lpddr3 ram.

It's not exactly a 1.9GHz SD600 (APQ8064T, APQ8064AB) downclocked, but a Krait 300 variant (APQ8064-1AA) that is intended to run at 1.5GHz, so overclocking I'd imagine would come with plenty of throttling and battery consumption.
It really is the perfect HW for current generational need, it's not like we can do pro-grade stuff that needs Core i5 power, so it's best using the stock clock which is well balanced between performance and battery life.

I can't imagine overclocking to 1.7 would drain anymore than a percent or 2 of total battery consumption. With the current setup it looks like it can even be done with the same voltage settings to me.

I mean, I'm not the type to OC obsessively. I mean, underclock = better battery... But if we could bump up to "stock" it prob wouldn't be that bug of a difference. BUT apparently this model of the S600 is supposed to run at 1.5. I'll probably keep it there.
Sent from my Nexus 4 using Tapatalk 4 Beta
On Wikipedia it says that the APQ8064-1AA has a way faster memory speed than the S600 in the HTC One (1600MHz DDR3L 12.8 GB/sec vs. 533MHz LPDDR3 8.5 GB/sec).
I don't know if I can trust it, but...

Underclocking doesn't necessarily lead to a better battery life. It depends on the efficiency at the actual frequency. If you underclock, the chip needs less current but needs more time to finish the work load because it is slower. So what matters is total energy consumption: W = U * I * t (Voltage * Current * time). So to save energy, the current has to decrease more than the time increases for a given workload. Also we can see that decreasing the voltage (undervolting) also saves energy (in this case we don't loos calculation speed because the frequencies are untouched)
Hi there could I get some advice please.
Which device would you use for gaming?
I have a rooted Nexus 7 and have opted to use that for gaming due to battery life (thanks to mkernel I think) 32gb storage and screen size. But I have found that performance can be an issue with some games. Particularly need for speed that lags like hell but one of the best games in my opinion.
Whereas need for speed runs smooth on my nexus 4 I believe due to the snapdragon and 2gb ram maybe.
Can anyone restore faith in my Nexus 7 for gaming or should I consider moving onto Nexus 4. The only issue I have is the limited memory and battery life.
Does the Nexus 7 1st gen. Have the hardware to be a great gaming tablet?
Would gladly hear some other views and opinions or ways to improve the performance of the Nexus 7.

Idk man, I've played "heavier" games on my N7 without any issue. Maybe you can try overclocking the cpu and the gpu, clear the memory.
Btw, which version of NFS lags for you?
Need for Speed most wanted. I over clocked cpu to 1700 with m kernel but not messed with gpu settings as I'm still new to the modding! What gpu setting do you recommend as I use trickster mod and sure I can change the settings there. Quickest and easiest way to clear memory too. You mean ram right?
Need for Speed mainly lags when approaching police road blocks. But I have read somewhere it's the tegra 3 and can't cope with graphics or summin like that.
Thanks for your reply by the way.
Would appreciate your thoughts.
Sent from my Nexus 4 using xda app-developers app
I've tested the NFS:MW and hadn't experienced a single lag.
Lately I don't have much time to play, so max CPU clock is 1200 and max GPU is 446. But as I sad, it runs without any lag.
What rom are you using? How much free ram you have when you don't play?
I'm using stock. My gpu is 446 also. Free RAM is around 400 to 430mb. Is this what you would expect? Do you recommend ram booster apps as I have heard they don't really do much.
Sent from my Nexus 7 using xda app-developers app
Nah, your ram is just fine as it is and 400mb free ram is fine. I don't really have any idea what could be the problem. As I said, it runs fine on my N7 even on 1200MHz.
Maybe there is an app running in the background with high I/O and/or CPU burst. Or maybe some files of the game got corrupted and takes longer to load.
Hi there,
Nexus 7 equipped with 12+1 Tegra cores is not much effective...These cores are CPU+GPU cores so no discrete GPU chip for Nexus 7. .. This can make processing slower..I feel... while on the other hand. Nexus 4 has discrete Adreno 320 GPU specially designed to render graphics;;..
I played GTA 3 on it and i am shocked that i find it better on nexus 4 than on my PC!!
Ofcourse Adreno 320 is a powerhouse of graphical computation for N4...
So my vote.---->> N4 > N7...

They do not have the same processor. They do not have the same cores either.
Simply put the nexus 4 has krait 200 cores. The moto x has krait 300 cores.
The krait 300 cores are faster clock for clock than the 200. They also of course have a clockspeed advantage too.
All of Qualcomms crazy naming scheme aside. The moto x has basically a dual core S600 at 1.7ghz. Think HTC one m7 with two cores. And those two cores run at the their max frequency quite a bit often to boot....
User psx on nexus 4 and compare them

Quick summary:
N4: APQ8064 Krait 200 quad core @1.5ghz
MX: MSM8960DT Krait 300 dual core @1.7ghz
2013 N7: APQ8064AA Krait 300 quad core @1.5ghz
S4: APQ8064AC Krait 300 quad core @1.9ghz
S5: MSM8974ACv3 Krait 400 quad core @2.45ghz
(the fact some are S4Pros and some are S600's means very little, it's mostly K200 vs K300)
The moto x / 2013 N7 / S4 are pretty closely matched perf wise, which makes sense as they're all the same platform.
If you jump two steps between S4Pro -> S600 -> S800 -> S801 then there's a fair sized perf change, much less so with a single step jump.
At stock clocks I dont feel my S4 or 2013 N7 are dramatically faster then my N4.
It's merely that the N4 has the shortest battery life of the 3 (both relative and obviously absolute)
If you OC your N4, you could easily catch up in raw cpu power (if you ignore the fact that you could OC the other device too).
I wouldnt be too surprised if a K200 @~2.0-2.2+ ghz would equal a K300 @1.7-1.9ghz, though you'd shorten battery life even more on a already short life device.
If you could magically OC a N4 to ~3ghz, I wouldnt be surprised if it could keep up with the S5, I also wouldnt be surprised if it dies in 5 mins.
The N4 is very disadvantaged when it comes to thermal throttling, since once it hits the heat ceiling it drops like 20% in performance so it doesnt overheat.
You could also do the heatsink hardmod if it was really important, it's a rather easy mod (if you dont mind the fact you need to take it apart to do)
All devices have a thermal ceiling, but the N4 is usually disadvantaged when it comes to that. It's far easier to hit it on a N4 then any other device.
You could also do the qcom dalvik+bionic mod, it improved benchmark scores on my N7 by 15% (but much less on my N4, also I said benchmark and not "performance", it's very hard to quantify general performance/smoothness)
I think there was a F2FS mod for the n4, if there is and it works you could dramatically improve storage speed if you use that.
Finally you could always throw random build.prop mods, placebo effects are always the best as far as cost/performance goes.

Moto has generally simply been spinning for marketing.
The fact of the matter is that the MSM8960DT is basically varient of the APQ8064AB/Ax that has 2 cores instead of 4.
Devices newer then the MX also have similar coprocessors now to offload idle sensor work, it's a general part of the S800/801 platform.
There's nothing stopping a manu from including them with any equivilent quad core soc,
which is essentially what qcom did with their own coprocessors in the S800/801 platforms.
Battery life on it is about equal to it's APQ8064Ax cousins since they're obviously the same cpu.
Depending on the rom/kernel, you can turn 2 cores off on the N7/S4/whatver,
but you cant turn 2 more cores on the MX.
The moto x has a slightly faster cores and clock speed but as there are too less cores it is slower. The reason it seems faster is the software optimizations Motorola have included on the moto x. Things such as optimized dalvik and bionic and using F2FS. If you install these on the nexus 4 i think it will be quicker.

The nexus 4 is just not quicker no matter what you do.
Quad vs dual is irrelevant. There aren't hardly any workloads on mobile that even require four cores let alone max them out. And if you do its going to throttle very quick anyways.
Krait 300 cores are faster period. The moto x is faster period. The hardware is just faster.
http://www.anandtech.com/show/6747/htc-one-review/11
No software optimization or trickery. Krait 300 is just faster. It doesn't seem faster. It's faster.
Krait 200 was already a old core relatively speaking when the s4 pro came out. It is the same core as the last gen SoC in the s3 class devices. Just with a newer gpu basically.
Can't believe people are still having this silly discussion.

Yes krait 300 is faster than 200, around 20-30%. The fact the nexus 4 does have 2 more cores does make it faster and just because "There aren't hardly any workloads on mobile that even require four cores let alone max them out" doesn't mean the moto x is faster ( at least by my definition of the word). The nexus 4 already beats in benchmarks but if the moto x does beat the nexus in things such as UI its because of all Motorola's software optimizations like i mentioned before.

In the majority of benchmarks that moto X wins. It even beats the quad core s600 devices in many of them as well. Even giving up 50mhz on the gpu to them.
Throttling is a big deal. Those chips throttle quicker and their clockspeeds go way down. The moto X spends more time at the highest clocks.
http://www.anandtech.com/show/7235/moto-x-review/7
Overall no matter how you try and slice it. In the majority of use cases, real world and benchmarks. The moto X is faster
And it doesn't beat it in stuff like ui because of some optimization. It beats it because it is a significantly faster clock for clock and has a clockspeed advantage. And browsing around the ui doesn't use for cores on top of it all. You can easily show that on your nexus 4 with a custom kernel and setting it to dual core only.
It's faster because the platform is faster.

What benchmarks are these? I know the motox has great GPU performance (mostly as it's one of the few snap 600 with a 720p screen) but in CPU performance it usually is lower than quad core s600 devices. For example in geekbench. But yes the moto x is faster than many in real world performance but this is largely due to all Moto's software optimizations.

The article tells you what is used in it. Also for the gpu test many of them have offscreen testing as well which negates the resolution difference.
Again it's faster in many cases because the hardware is just faster period. Just as taking a HTC one m7 and a custom kernel with 2 cores disabled would be faster in real world performance as well compared to nexus 4.
Real world performance is not some micro level threaded benchmark test.

What makes you think that only 4 cores are working?
I don't know in the Android world, but in PCs the applications must be written expressly to use more than one core. And the SD 615 has 4 cores that runs at 1.7 MHz max and the other 4 at 1.0 MHz max, but the frequencies could be lowered by phone makers to increase battery duration.

Yeah but I had my phone on performance mode and it's using half of the cores, if the other 4 max at 1.0mhz then why are all games that I play (3D Wise) are slow? Is there any way I could fix it? Could overclocking via CPU managing apps (using root,) work in my situation?

Four cores are high-performance, and four cores are low-power. The performance cores suck up a lot of battery, so not for use with background tasks. The low-power cores are useless for pretty much anything but background tasks, so they're not for use with gaming, etc. The fact that your apps are only using four cores is normal.
Also, as for your gaming performance, I've actually done some testing on this and it turns out that on the ZE551KL, the GPU is way underpowered. No amount of overclocking can fix the abysmal GPU performance on the ZE551KL. This doesn't seem to happen on other models, either, so... yeah.
@gyropepsi: yes, that's correct, the eight cores are not "equal". You have four cores for general CPU use and another four for higher CPU use. They cannot be used in the same time, they get switched to save power. It's actually called "dual quad-core".
https://www.qualcomm.com/documents/snapdragon-615-processor-product-brief
Other manufacturers have one core for low processing and four for high processing. Those phones are doing great in tests but they really suck in daily usage.
@sensi277: I would't say abysmal performance, but yes, it seems to be lower than the Selfie in some tests. However it moves VERY good for a phone, 3D tests on phones are just for kids, to brag about their phones. Nobody does real gaming on a phone.
