so, i am using the Fear Rom and with the OC karnel. i played around the max sittings to 1.4 and tried quadarant. amazing score of 4150. nice... but what will happen if i keep it at 1.4 ?
will it over heat the phone / burn the GPU/CPU when playing games for example ?
i understand the battery life will be shorter. but what other disdvantages ?

You could dmg ur cpu. But Tegra is known to run 1.8Ghz stable. So with 1.4 you should be good.

Oh!! Great 1.8Ghz but only 1.4Ghz is very drain my battery to much.
In the long run, your cpu might get affected but its shouldn't happen so soon.
That said, in my honest opinion, don't need to OC the chip.
The same OCing rules apply from the PC World. The same batch of chips have varying maximum OCing capabilities and thus different stabilities. Although you can stably run a chip at a higher clock, it will definitely shorten its life (Sometimes it could kill it in a year, sometimes beyond what we can measure.). Chip makers purposefully OC chips during tests to simulate the stress effects of using the chip over a long period of time (OCing that makes it seem like the chip is being used for months or years.). Nvidia sticks the Tegra at 1 GHz half because it's cheaper to do so (don't need to ensure higher clock rates which would mean a larger percentage of their chips won't last doing it.) and half because of marketing (At the time, no one has 1.2 GHz like we do now. From what I've seen, Tegra 2 can do 1.2 GHz easy.).
So what it comes down to is how long you plan on keeping the phone and how lucky you are. =)
Imo, in the interest of power savings (P = (V^2)/R), the gains of OCing having an exponentially worse effect on battery life.
imho theres currently no point in oc'ing the Tegra2 in Optimus at all.
Theres no real life benefit, only theoretical benefit when running benchmark apps for show off.
Theres not a single application or game out there today that require more processing power than what the Tegra delivers at 1ghz - and not a single one out there that will run any better or faster by oc'ing because the demand for processing power to run the application or game at its maximum capacity are allready met at 1ghz
Basically there are only negatives in terms of decreased battery and cpu life for nothing but a screenshot of a higher quadrant (or whatever) score
If at some time in the future you should run into a game that would not run smoothly unless the cpu are oc'ed then it would make sence to do so - but for now not.
The games available today either do run perfectly smooth at 1ghz or if they dont, then they dont because of poor programming or other factors and they would still run poorly even if the cpu are oc'ed
Actually there are real life benefits until you find a game which really lags when you run it. Meaning, you should leave it as it is until next year.
It may damage the CPU like what others say but since lower clocks are undervolt it might last as long as a non OC (Stock).
But it will kill the battery faster as you will have to charge more often due to the higher power draws.
Hi,
I saw BravoMotolora's article about CPU binning, and I thought that it would be great if we compare CPU bin and voltages.
It will be great to know the relationship between voltage and PVS number.
Please follow this procedure
1. Install a custom kernel that lets you do undervolt, e.g. franco.Kernel
2. Do what BravoMotolora said
3. Undervolt your N5 by 25MV
4. Run Antutu
Then, you might see your N5 rebooting or giving you a Antutu score.
If you get the score, go and try the procedure again
I got to -50MV with PVS1 N5.
Please post your results(undervolt that you did and your N5's PVS) here!
Can you not do this?
Do not do what? I mean most of guys here will do undervolt to save battery anyway so won't it be good to share some intel?
Sent from my Nexus 5 using XDA Premium HD app
I'm the same as OP... I have PVS 1 and the max I can UV is -50mV.
you do realize that many custom kernels set their voltages different than default/stock, and differ among themselves? for example, if you go -50mV less on using franco kernel, and go -50mV less using trinity kernel, it means nothing because their voltages differ to begin with. i mean you cant really compare each others voltages that way. you would need to write your voltages in real numbers, and cpu speed steps.
I honestly never saw a huge benefit in undervolting. It can also cause errors which lead to worse battery life.

it's a lot easier to underclock 20% than to undervolt 10%, which approx. gives you the same active power savings. It's a lot safer too, if you don't have a spec sheet for the CPU handy.
underclocking does nothing to idle power (or leakage power) though
This phone does pretty well arlt idle I think. Can't imagine you would see much gain from UV.

I have a PVS 2 and can undervotl -75mV accross the board and -87.5mV at 300Mhz.
So 2,26Ghz I can run at 0.975 Volt.
CM11 with Bricked Kernel.
Together with Sync off, Google hotword off and optimized automatic brightness I get constantly 5 - 5,5 hours screen on time with websurfing, mail and music stream.

Underclocking drops the performance of the phone, as the peak performance is not available when needed. Undervolting on the other hand gives you battery savings without affecting peak performance at all. If done too aggressively, it can make the phone unstable, but there is never any danger of hardware damage. The instability will at most cause errors, random reboot, or a freeze up. If this happens, you know you've pushed too far under, and you can bump voltage closer to stock after booting the phone back up. If running stably, undervolting is actually marginally better for your phone hardware than stock voltage because you are wasting less of the energy in heating up the chips and damaging them.

i underclock, sometimes to 1036mhz max, with all 4 cores always on by default(no hotplugging). sure, in a benchmark itll score less, just like i expect to score more when im overclocked. but to the normal user, they would never be able to tell that my phone is only clocked to 1036mhz. meaning the user experience isnt lowered in any way. even intense gpu oriented games dont show that im running underclocked. so when you say it drops the performance, it isnt entirely accurate.

Sorry, but CPU underclocking means always a drop in CPU performance.
When you compensate this drop in your case by always having all four cores active you produce more heat with the active cores.
(and I estimate it will produce more heat/battery depletion than the original phone settings. (max 2,26Ghz and variable core usage)
When you argue that in general a normal user is not realizing a drop in performance due to underclocking...fine.
But it will always be a drop in performance.
Undervolting in opposite to underclocking produces no drop in performance but actually a rise in efficiency. (and thats what CPU/GPU development is all about).
Less heat, less battery depletion, same performance.
Why not taking advantage of that by undervolting?
Its free lunch.

I agree with you here. 1036 mhz is a great CPU speed for running the device and most apps. Most games UC the CPU for better battery temp like in PPSSPP. Less temperature throttle and more stable frames per second.
Benchmarks are a difference story though but who cares about those. UC is lag free, and buttery smooth so why not?

again, sure, if youre benchmarking the performance will drop, yes. but if its something that the user doesnt see or feel, then its irrelevant.
no extra heat is produced. also, i get 5.5-7h screen on time with very heavy use. granted, i use the browser much more than i game, but thats what i use my device for mostly.
when needing the extra performance, or wanting to, i overclock. everybody uses their device differently, has differing needs. i would never say one way is better or worse than the other way.

You can do everything you are already doing, but also undervolt, and your battery life will increase, without affecting your performance. Your performance will be different than my performance (because I don't underclock), however imperceptible as it may be. So undervolting is still better than not undervolting, even for you.
Using EX kernel 3.27, underclocked to 1.5Ghz, undervolted to "700 min" and using "stock" thermal throttling setting. Rock solid and it barely even gets warm now. Responsiveness and performance is only a touch worse than stock; the only places I really notice any performance reduction is in intensive games and app install times. Battery life is massively improved.
I feel my Z3 Compact performance is no where near the performance at Snapdragon 801 is supposed to give. This phone to date is supposed to be one of the fastest Graphic performers and should be able to play games like Ashphalt 8, NOVA 3, Modern Combat and those mainstream graphical games at 60FPS no problem as i've seen in other phones with Snapdragon 801 like the S5, One PlusOne, HTC One M8 etc but my phone seems to play these games like bout 30-40FPS and when a menu transition happens it's really choppy.
Even though this phone is also 720P and with benchmarks on websites like PhoneArena, GSMArena they have scores on geekbench 3 bout 3K while my one is 2.2K constantly, GFX 2.7 (T-Rex Onscreen) bout 40FPS while my one is like 25FPS. Performance is definitely noticeably slow.
I notice that on CPU-Z app that my GPU frequency never exceeds 330MHz, i wonder if you guys are like this too and also my Governer thing is on Interative if that's normal?
I have conducted these results without Stamina mode or performance restriction on. Nor is it rooted or anything.

I have same problem, but not in the benchmarks, my gpu stocks at 330 Mhz while playing games. Actually maximum frequency shown in cpuz is 330! This is weird.

Should be similar to the other Mali GPU devices
The Qualcomm adreno is unmatched (it's an anagram of Radeon as Qualcomm bought the initial ip from and)
If you buy your phone to play games... There's no reason to buy anything other than a snapdragon with an adreno you
Otherwise it makes little difference in real life use
As far as I remember... Qualcomm was always behind on CPU benches but generations ahead on GPU performance and efficiency
Well nowadays they're ahead in cpu department too....cuz you compare 970 with 845,and 980 w 855(or whatever his name is).
Regarding buying phone for gaming I agree. In the segment up to 500-600$. Anything more than that it should be a complete package...phone that is capable of everything equally capable...and competitive with rivals. Ofc that's in my ideal world
Well, I was thinking of buying 7 or the pro, but the performance in games has me in doubt, someone has played heavy games, such as Génsei impact, how is the performance in this game
It plays every game fine as long as you don't max out the settings.

What I mean is that the games tend to be tuned for their best performance out of the box. If you jack up the settings beyond that, you'll start losing frames, especially in Genshin since just about every Android struggles to get 60FPS maxed out.
Tensor is basically a tweaked Exynos 2100 and as you can see from the guide here, it's a high end performer (look at the table, I don't think they have updated the blurb about Exynos being beaten by a 3 year old chip because that's the 980, the 2100 is much better and the GPU in the Tensor G2 is better than the 2100's anyway).

saccording to that table the s21 With the 2100 it performs well, but what about warming up with pixel 7, how will it be, does it lower performance or does it maintain it?

All of these devices heat up and throttle, the Pixel is no exception, but its relative average performance is still better than the Exynos 2100.
You can also cut down the heat and increase performance by tweaking down graphics settings obviously. It's not really that noticeable on these displays anyway.
Here you can see it running around 45~60 FPS on high on a Pro. I didn't check if he is running it at 1080p or 1440p though so performance on the 7 may be better or the same. Dude comments that even the 8 Gen 1 has the same frame drops.
Thanks , bro
