[Q] Linpack curiosity - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

More of a curiosity than anything, stock firmware was scoring ~300 single threaded, ~700 multithreaded. I flashed CM10.1 last night with the KT AOSP kernel and now its getting approximately half that.

Don't trust benchmarks. They are of limited value.

Anyone get low quadrent scores?

I am running 4.010.13 with Richards kernel oc to 1500 and my quad score was 2300. My brothers Droid x3 scored 2500. Also I see scores all the time well into the 3500 for the a500.

i get 3000+ running minimalist only oc'ed to 1.2
When I of to 1.2 I only get a score of 1600!
How is is that rom by the way? Any bugs?
Sent from my A500 using XDA Premium App
Runs amazing much better then stock although I am noticing a significant battery drop :-\
I might try out that rom. All of a sudden my tab feels like its slowing down and lagging a lot! I do not know what is causing it to slow down but I am going to try another rom that will hopefully fix it. :-[

Under clocking on stock ROM?

I've noticed that the default clock speed for the Nexus 4 CPU is 1GHz - 1.2 GHz (for my phone, anyway), but any attempts to underclock either of these values with many of the available CPU control apps have been useless, for after about a minute of usage, the clock speeds return to default, despite the CPU governor remaining as my choice.
I'm wondering if it's actually possible to effectively underclock/overclock on a stock ROM. If not, are there any battery-life optimized roms/kernels out there?
Sent from my Nexus 4 using xda app-developers app
Are you rooted? If you are, I don't think you should have trouble underclocking on stock. What app are you using to change your CPU frequencies? Try using a different one.
Trinity Four kernel has given me the best battery life so far.

You need to be rooted, use setCPU (app) or flash a custom rom
Can I flash the Trinity Four kernel over the stock ROM without having to wipe everything?

4.3 reduced antutu score or its just me..

K guys.. I am not sure if its 4.3 or something else.. Can someone confirm.. I used to get 18000+ on my 4.2 n4 and over 24000 with faux overclocking kernels for 4.2
Now i am getting 14000 - 16000.. With 4.3..
Sent from my Nexus 4 using xda app-developers app
it's 4.3 and new update of antutu....
you can use custom rom/kernel or some tweaks so you'll get over 23k
Just you...

@Testraindrop what kernel / rom are you using? I compared and my cpu and ram scores are much low..

try cm based roms and a good kernel like Matr1x or trinity

Will try the cm 10.2 but its still nighty.. And regarding kernels I was always under the impression that faux and franco gives the best performance..

different kernel works and reacts differently on different devices and different roms. test it out to find YOUR perfect fit.

Try the S4 dalvik patch that's floating around here. Boosted my score to 20k+ on PA 3.99 with stock PA kernel at 1512/1512.
Using this combo as my daily driver since a week and no problems so far.

What kind of numbers did you get before the mod?
Sent from my Nexus 4 using xda app-developers app
Around 16-17k if I remember correctly. Also don't forget that heat throttling is pretty aggressive on the N4. So make sure your device has cooled down before the next run.
Pro tip: put your N4 onto a cold ceran stove when benchmarking. They're made to conduct heat efficiently and will keep your device cool
Well I wouldn't give those numbers too much credit...
they represent more the settings that you enter, than device performance.
I for instance use the latest franco Kernel. With the settings I use every day (interactive governor, default clocks), I get arount 15-18k in antutu. But the device feels as snappy as hell in normal usage and gaming.
If I switch to performance governor, ramping the minimal and maximal cpu clock up to 1512MHZ while raising the cpu throttling from 65 to 90° I reach antutu scores in the range of 20-22k.
But I obviously would never ever use these settings every day.
That beeing said, these numbers do not really represent how the devices behaves in every day usage, which is much more important to me than any number, a benchmark puts out.

I am not trying to reach higher antatu numbers.. what I was looking for is to test out which kernel and what kernel settings gives me max power...

I have a couple of questions:
It's your phone still working like it should?
Do you really care about the scores you get to be able to enjoy your N4?
Do you think the scores of benchmark really say everything about your phone?
If you compare a S4 or M7 with a N4, and in one test (by chance) you get the same scores, do you think your N4 has the same power as a S4 or M7?
Stop worrying about benchmark scores, I used to be like that bench-marking all the time, at the end I just got tired of it!!!
Now I just enjoy my phone the way it is.
Good luck!!!
CM-10.2 and CM kernel got 20728

btw. Antutu 4 score: 21336
Benchmarks are useless, its how the device feels when using it what matters.

What can all increase a an tutu benchmark score

What?
Turning off every feature the phone has including data and wifi. Different rom and kernel combos. A cold phone. I'm sure theres more.

Low Bench scores?

First off I know benchmark scores are not that important, real life smoothness is. However when running Antutu Benchmark I consistantly get scores between 25k and 27k, while the chart puts the Note 3 at >35k.
LI am runnig a custom ROM, X Note 5.1 with Faux kernel. Is this kind of score to be expected? I have no real problem with performance but I'm a bit OCD so I would like to know what is causing this.

Maby it's the kernel you use, I am also on X Note 5.1 and get 35/36k.

I think I'll quickly flash the stock kernel and try again. Will post back if that makes a difference.

little improvement
Unconvincing improvement... What other things can cause low benchmark scores? I use the International SM-N9005 Snapdragon 800 version.
