[Q] Performance difference from different kernels on different roms - Nexus 4 Q&A, Help & Troubleshooting

Hi,
I've noticed a huge performance difference between kernels and the roms they're used with.
For example:
I was using AOKP and Franco kernel and got around 20000 antutu points, I've switched to Carbon Rom (because of the build in pie control) and Franco kernel and only get around 13000 points, that's a huge difference.
As a test I've installed Matr1x-kenel on Carbon and get around 21000 points.
I really like Franco-kernel and all the tweaks it offers but don't like the huge drop in benchmarks, I know benchmarks are not a real representation of actual performance but it's still a big difference.
This also occurs in Quadrant and Geekbench.
So my question is why does this happen?
Aren't most roms supposed to be compatible with most kernels?
Thank you in advance.
Best regards.

I can't answer your question as to why that happens (no doubt someone else will) but you seriously should just stop bothering with benchmarks and use your own eyes and experiences as a measure of how good a kernel/ROM is. I doubt you could find a kernel which made the phone visibly slow or that affected usability so I don't see what your concern is tbh.

Thanks for your answer.
Yeah, I read that a lot on XDA, don't trust benchmarks...I understand that but they must have some meaning.
I mean, if not why do they exist or do people bother using them?
To be honest I don't really notice any real performance difference between most kernels I've tested.
Best regards

some roms include many optimizations(like skia/dalvik, krait optimizations, and others), while some dont. its not thekernel thats crapping out on you, its the rom.

your eyes can be decieved.. they can see whats happening in the ui for example, but you can not see the complex calculations that are being performed or how your cpu is really performing. you can have a slow device whos ui is quick.

OK, I can understand that not all roms are equal but why does changing the kernel have such a seamingly big impact?
If a rom is bad to begin with it should stay that way no matter what kernel you use with it.
Offcourse what do I know, I'm not a developer so my knowledge on the subject is limited.
I'm just trying to understand what's going on...

kernels vary too, and they impact greatly because they control just about everything in the phone, kinda like a brain. since the kernels themselves vary, one kernel might be better set up than another to deal with certain code from a certain rom. and then also, every phone reacts differently to each kernel(and roms to a point). thats why its recommended to try out different kernels, combos. only then you can find the perfect combo for you/your device. what works great for somebody, can be lousy for another.

OK, so if i understand correctly it boils down to this:
1. You can do benchmarks but don't base your opinion on just the benchmark scores.
2. Roms can vary greatly in optimizations and efficiency of coding.
3. Kernels can also vary greatly in optimizations and efficiency of coding.
4. There's no such thing as a "best for everyone rom/kernel combo".
5. Not all roms/kernels play equally nice with each other.
6. Play around with as many roms / kernels as possible and decide what works best for ME based on MY experience.
Thanks for the advice.
Best regards.

Its been well over a year since I ran any benchmark of any sort but I tested Franco and carbon because that's what I'm on and you mentioned low scores. I'm on Franco m3 with some tweaked settings and carbon nightly from 7-5. Antutu gave me 20636. I'm using stock CPU and GPU frequencies.

Maybe the nightly Carbon rom is more optimized?
I'm on Carbon 1.7 Stable and used Franco nightly 162 to test with.
When I benchmark I try to be as consistent as possible ie same temperature, performance governor, airplane mode etc.
I even cooled my Nexus in the freezer for some minutes to eliminate thermal throttling (yeah I know, watchout for condensation) but still got the same low scores.

It might be, I didn't do anything special. I left all my background apps running, didnt close anything in the recents, didn't cool the phone first. I just downloaded it and hit start. I use the interactive governor tweaked a bit, and I also tweaked the hotplug settings so it more readily onlines all 4 cores instead of waiting for some of the higher loads to trigger it.

Well, I had to try it myself so I did a factory reset, cleared system,data and dalvik, installed latest carbon nightly.
With stock kernel I almost reached 21000 points, with franco I barely get 17000 points.
Very strange...
edit:
I stand corrected, did a second benchmark and am now getting 20880 points...

are you benchmarking with your cpu speed benchmarked set as highest and lowest cpu speed? you should. if you dont put the same cpu speed as highest and lowest then itll scale up and down. if it scales, you dont actually know what speed its testing and it gives you inconsistamt scores. you want the cpu speed to be the same throughout the test.

When I benchmark I set the governor to performance, this should keep the cpu running at maximum speed without scaling unless I'm mistaking...

meh, performance is the worst for benchmarking. its such a deceiving name. try either ondemand or interactive. set your cpu speed to be the same high and low.

Woow, that's a great tip, I now get 22003 points with Matr1x-kernel.

In theory, sure.
In practice, I don't think it's sustainable. You could modify a kernel and try for yourself! But overclocking your cpu is going to degrade it, and the gain wouldn't be that noticable. Also it would be pretty unstable I suppose!

I would encourage you to do a little more research into overclocking. Some kernels allow up to 1190mhz through setCPU and i have played games at this speed - so for real life use that speed has been stable. A thorough benchmark will better test the stability, but only if you raise the voltage will the CPU's life be effected, but if by only a small amount then you will probably upgrade before the CPU is anywhere near giving up. I do agree with the post above that there will be little noticable change in experience, but this will show in benchmarks.

Best Kernel out there?

which kernel out there is the best right now? in battery life and speed
theres only one that fits best battery and fastest.. trinity kernel.
I like Trinity but Motley also did very well for me.

This^ look at it this way. The nexus allready has great performance, it will handle any game you throw at it. (Unless not optimized for tegra 3) so wht else do you need? A kernel that gives amazing battery life. And what kernel is that..... \l/ TRINITY \l/

battery right now..
speed..
Ill say motley. I tried trinity kernel. Its good. But I getbetter performance,stability, and battery life with motley. All these battery screen shots really mean nothing. Why? Because none show real heavy use. I can easily get the same stats or better with light to moderate use. Show me some stats showing 8-10+ hrs of screen on time. With some heavy app or game usge. Anyone can use device for a few hours. Then leave it in deep sleep and show the same or better stats.
I've tried all the kernels out so far. They are all good. Its a matter of personal preference of features you want. Some pack things others don't. MOTLEY 'S ATM is the only linaro based kernel. So its using new additions/components. Better optimized. Benchmarks are cool but its real world performance that matters most.
I'm running stock rom with motley latest linaro based kernel with Zram, then CPU overclock @ 1.624ghz and gpu overclock @ 520mhz. I'm also undervolted -75mV across the board. So my temps stay low. Which equates to my device running at a higher performance speed longer.
The best thing about stock rom is I can measly flash different kernels and not have to worry about flashing a rom and setting my apps n all THST all over again. I can flash a kernel with no wipes and be good. Plus stock rom is the most stable ATM. Can't lie though, I am anxious to flash some roms. THST paranoid Android one looks really good. Along with the pure linaro based rom. That's the great thing about choices.
Its not a matter of who has the best kernel. Its more about what you looking for in features and personalizing your device to cater to our needs.
Asking who has the best kernel is like asking who is the best developer on xda. I don't think that's fair to the developers as they ALL work hard on roms or kernels. Forget the popularity contests.
THEY ALL THE BEST lol. Some are just more seasoned than others. Which is OK. I love the fact we have variety of things to choose from. I've been impressed with trinity kernel, based on scores I've been seeing. But I'm also impressed with faux kernel and its a more straight forward one with lots of new Linux commits and additions. All the kernels have a personality of their own. I love the fact that twrp makes it very easy n simple to try out any kernel I want for nexus7. No matter who makes it. Every developer has its followers. You also have people who like to try out different setups.
Choice is a good thing! That's what I love about Android.
I've got to say for me trinity is the best kernel for the Nexus 7, updated daily and great communication with the dev makes this an awesome kernel. The trinity toolbox app is the icing on the cake.

1. trinity kernel has been using linaro since april of 2011, on the nexus s, the gnex, and now the nexus 7.
2. zram is a placibo. theres nothing there
3. stock rom is good, but i prefer a pure aosp build. no, they are not the same.
4. and the last two paragraphs are the absolute truth.
5. really, you should try them all, let your device tell you which kernel it likes the best

Thing with zram is, its not for getting higher benchmark scores or immediate performance. Its more so for heavy multitasking. Is been proven to help. The placebo is on people who think its supposed to provide some immediate result. If someone is a heavy multitasker on their device, then zram would benefit them. If you not much of a multitasker, then zram will show no Bendix for you.
You are right though, about trying out different kernels and such. Pure aosp rom sounds good. I just hate having to reset up my apps n stuff. I know titanium good for that but me personally, I'm waiting for roms to mature more and have most things, of not everything working. All roms so far seem to have something not working yet. Which is fine. Nature of the beast.
I think I might give trinity kernel another try. I did buy the tkt app. But never used it in conjunction with the kernel. I bought it just for the automatic script it runs..lol plus to show support. I heard tkt app works best with trinity kernel plus allows you to tweak features only in trinity kernel.
Ill download the latest build Trinity has and see what's up. Performance and better battery life is always a good thing. Its gpu is overclocked to 520mhz also?
Trinity HANDS DOWN its been 3 hours on sleep and ITS still at 100%! + the ridiculous speed along with the power saving features. I may be new to the Nexus 7 scene but this is hands down to godly .

im not sure if gpus oc...but when u underclock..theres absolutely no performance difference..and saves battery too! 102mhz-1100mhz on demand/deadline..god like battery life. 4 hours screen time...still 45% left...shouldve been more if i didnt flash roms in between battery life. also under clocked, gta 3 and cs portable runs great and smooth still.
thanks to simms, I tried out trinity again. I flashed the latest builds. ran some benchmarks. for some reason, my device doesn't like the highest speed on benchmarks. it kept rebooting during them. so I stayed at 1.5ghz. governor I used was performance and on demand. for scheduler I ran with deadline. i forced cpu online and put fysnc on faster, thanks to TKT app. on quadrant, I was more concerned with seeing if I could achieve those crazy high I/O scores. which I did. my overall score was good but I've gotten higher on motley. it could be higher on this kernel if I get the 1.6ghz+ speed to stick. I was more impressed with my rl sqlite benchmark test. scored 18 seconds overall. which blows away the competition.
so I'm impressed with latest version of kernel. definitely better than the older build I ran of it from before. some things I've noticed though. where is the ability to undervolt at? no option in tkt app and the voltages tab disappeared from system tuner. also, this build gpu isn't overclocked. or might be better for me to say its definitely not running at 520mhz. I could tell this by the fps from quadrant. its running 59-60fps. on motley with 520mhz gpu I get 70-80+fps. just some things I noticed. not necessarily drawbacks. kernel runs very good. just got to figure how to make higher speed stick. since I can't seem to adjust voltages on this build, I can't increase voltage or undervolt it. if this can be done on trinity kernel, let me know how. its not showing voltages in tkt app or system tuner.
overall very good kernel. will run it for a while to see how battery life is. I will likely underclock it like above poster mentioned for best battery life. I noticed nexus 7 still runs great underclocked. no lag.,no matter what kernel I'm using.
I've attached screenshots of my benches on latest trinity overclocked @ 1.5ghz. I know my device can take 1.6ghz cuz on motley I can run the speed fine, even through benches. so have to see why its not taking on trinity kernel. maybe voltage needs to be increased.
so it doesnt matter if trinity is still in experimental? its that good? i guess ill try that one out

there are more features that are going to be added, theyre being added all the time. ask gnex owners how the options grew(same app btw, different devices running trinity see different features in the app. so you purchase it once, and use it on multi devices. btw, voltage adjustment will be added, remember how new development is on the n7. also, if other developers added the options into their kernels, theyed be able to use those features with their kernels

thats just trinitys method of rotating the kernels.. starts off in experimental(every kernel is tested to boot and run before it every appears here), then it graduates to prerelease if it makes the cut, and then if you guys like it it makes its way to release. its just that trinity development is so new here that there isnt a prerelease yet

I've underclocked mines to 1.1ghz also. battery doesn't want to budge from 100% so far..lol. it's barley sipping battery. the UI and browser is fluid n smooth at this underclock. which is a good thing. the real test will come once I play nova3 shortly. if it plays lag free on this lower speed then underclocking is a winner. I set my governor to interactive though. you get better battery life than ondemand. using deadline also. with fsync set to faster.

I understand nexus 7 is still infancy, developement wise. its cool. just wondering if those features were included since the option disappeared. I could undervolt or increase voltage on motley kernel. the tkt app would let me do it on THST kernel as the section shows for it. but I like using system tuner for undervolting when I was on motleys kernel. can't wait to see what new features get added. plus once I get my new phone, hopefully there'll be a trinity kernel out for it so I can use tkt app with it. the build is very good.

Interesting, 70-80fps, more than the panel.
You were interested in battery in an earlier post, this is me feeling meh and couching most of Sunday.
EDIT: Yes, emailing, tapatalk, browsing for laptop and not finding any, reading news in Pulse and flipboard, tweetcaster and testing slice(s?), gtalk, not heavy usage obviously. Screen wasn't on unless The Seven was used though.

Nexus 4 Benchmarks that are all over the place?

Ok so I've been tweaking my phone, doing everything in my knowledge to make it faster. I am using the stock rom with faux123 mako jb enhanced stock 422-r2. So my first benchmark on Antutu i got 18003. re-ran the same benchmark again with the same tweaks and got 14206 and thought it was anomaly so i ran it one more time and got 16142. I went back and re tweaked everything and my scores were every were, even in quadrant. the ranges were between 14200-16800. I haven't been able to get it back to 18003, maybe because i did it on a cold boob. but, the scores shouldn't be all over the place compared to benchmarking I've done on other phones. Any ideas on this and or fix it?
Your phone is throttling. Your first benchmark will normally be your fastest. I that's how it was for me anyways.
I've also had the same experience. It is certainly due to throttling.

Welcome to thermal throttling. I recommend a ROM with the Bionic patches (there is an otherwise 'stock' AOSP ROM with these in the dev section, I'm not a stock ROM user so I haven't any experience with it) and you should notice AnTuTu scores going up to 20k+ and a noticeable boost to actual usage. If your device will under volt well (most will do at least -100mV AFAIK) you may mitigate the throttling to some extent without compromising stability however I don't recommend disabling the thermal protection as is possible in some kernels due to the red light death issue. Throttling is only really noticeable when you benchmark back-to-back. It's not a massive issue in most real-world use. I suspect it will become more and more noticeable on newer devices as device manufacturers and SoC designers are forever scrambling to provide the best performance within the thermal constraints of a smartphone. As idle and low load consumption goes down with new processes, full load GPU and CPU thermals are forever increasing!
PA tweak improves benchmarks
I have to agree with you on this. The stock gave me an score of 17K (antutu). stability curve was all over the place in stock. switching to PA did not help much either, the scored went down to around 14K. yesterday i got an update from PA and flashing that gave me a boost of 18991. some good tweaks from PA i guess.

Ok so I've been tweaking my phone, doing everything in my knowledge to make it faster. I am using the stock rom with faux123 mako jb enhanced stock 422-r2. So my first benchmark on Antutu i got 18003. re-ran the same benchmark again with the same tweaks and got 14206 and thought it was anomaly so i ran it one more time and got 16142. I went back and re tweaked everything and my scores were every were, even in quadrant. the ranges were between 14200-16800. I haven't been able to get it back to 18003, maybe because i did it on a cold boob. but, the scores shouldn't be all over the place compared to benchmarking I've done on other phones. Any ideas on this and or fix it?

You are making faster a device which already is one of the FASTEST devices on this planet?

See if it's a governor problem, set it to performance and see if it levels out. GPU scores on antutu vary by @ 1000 marks, so take that into account too.

Underclocking CPU Gives Better Benchmark Scores?

Hi,
I don't know if these benchmark applications are valid, but I downloaded AnTuTu Benchmark and messed around with my CPU frequency. At first, I maxed out the core clock speed to 1.3 GHz. Next, I set the maximum clock speed to 475 MHz. When I set it to 475 MHz, I get a better CPU score.
Something does not seem right. Any thoughts?
...and now you know why folks don't trust benchmarks.
There is a thermal CPU control. By overclocking, you are overheating, and it's underclocking to prevent itself overheating...

That was funny to read.
By overclocking, your in fact under clocking or so it seems.
Yes that can happen. If it gets too hot it will probably start throttling each core back which gives worse and worse scores.
Right now I have mine up at 1600Mhz and I get better scores than 1300Mhz but as well I'm running nearly the same voltages that 1300Mhz is.
Nice!
Interesting guys,
I guess I'll just leave it at default settings
Too bad I can't root my device .......

I made a bunch of (repeated) measurements with a CM10.1 nightly kernel (at various Fmax settings) and the results were quite squirrelly. When I get a little time, I'll make some more tests and post up the data.
BTW - if you were using TricksterMod are you sure you actually applied the changes? You didn't provide any numbers (your results) and it is not uncommon for Antutu to produce 10% different results in that benchmark from run to run (and much much worse at different Fmax values!!) - so is it possible you just mistook a random variation for a "change for the worse"?

Yeah would have to agree here. Between voltage and clocks you can really affect any benchmark score. I knits I've been playing with it. Though a swing of 10% in AuTutu is pretty big. I've had maybe a few hundred points at most.

Antutu UX I/O performance score indicator for phone "snappiness"?

Hey guys,
would you be so kind and tell me your specific antutu score from the section named above. I had now 3 nexus 6p in my hands who feel more or less snappy (same setup ofc) and it matches with their ux i/o performance score.
With that being said, mine always comes out at around 3k with my girlfriend's phone having nearly 1k more. And like I said, theirs feels much smoother when using it.
Thanks.
Benchmarks are useless for testing performance. They're supposed to be taken with a grain of salt. Run a benchmark, now run another one. And 1 more after that. Each one will lower in score every time since the CPU temp is increasing which kicks thermal throttling into gear. Besides, what's your control group? Stock, unmodified? Because you'll likely have a number of different results from people running any combination of ROMs/kernels. Some may overclock, some may disable hotplugging, using different governor or schedulers, etc. The results would be widely different and wouldn't tell you much. Aside from that, I believe there is a dedicated benchmark thread buried in this section somewhere if you want to see others results or post yours.

i am not talking of cpu bench results. im well aware of the thermal throttling kicking in.
i/o performance should not decrease and does not decrease over several runs.
also i stated that both mine and my girls phone were running a clean pure nexus nougat build (latest) with ex kernel and same setup.
the scores differed in points to a degree where are i can rule out benchmark tolerance.
some more ux i/o performance scores from users here, perhaps?
