Just got my note 3 - SM-N900. And I've turned panicky.
Reasons:-
1) please refer to the attached picture - it shows octacore processor in the list. But there are only 4 cores shown below!!! What is this supposed to mean? Does my phone have 8 cores or just 4 cores?
2) my phone has extreme overheating issues. Is hardly 5 hours out of the box. I'm sure it's abnormal. Is there a fix?
Please help! Many thanks!

Try another application
this is Antutu - the best application for benchmarking and phone info. But is this normal? I don't know if it is! The N-900 is the Indian version of the phone. How come it's not showing 8 cores!? Or have I been cheated? I mean... has the seller done something to my phone's CPU before selling it? Phew!! I'm tired-,-

Hi
Yes This is normal
Don't worry about it
That's perfectly normal. It's because the Exynos Octa consists of two Quad-Cores.
A Quad-Core 1.9 GHz Cortex-A15, and a Quad-Core 1.3 GHz Cortex-A7
This throws off all phone info apps, because they can only detect one CPU at a time.
n900 have 8 cores but only 4 of them are active any given time. For more info refer to this. http://en.wikipedia.org/wiki/ARM_big.LITTLE

Hi,
An important question. The attached image shows android terminal from Galaxy Note and Fedora Core Linux terminal.
Since I have a i3 CPU with 4 cores on laptop, Fedora terminal correctly detects 4 CPU cores. Whereas for Galaxy Note, even though it has dual core ARM processor, I can see only one core. Is this correct? Please help.
Many Thanks,
Nikhil Bhalwankar

I'm not sure, but I think the Note turns off the second core when not in use. Perhaps some apps don't know ow to tell it to turn on?
I could be way off of the truth here.

After looking at the output, I thought it has only one core. Is there any way to confirm whether my phone really has 2 cores?
SystemPanel app can show you the 2 cores with real time usage and clock.
Every Note is dual core. Whether N7000 or I717. The processor has the ability to "turn off a core" when not in use in order to conserve battery. I wouldnt go by what the terminal is telling you.

Yeah many apps will show only a single core when the second core is shut down.
Desktop machines usually don't hotplug out extra cores.

Maybe its actually a quad-core and all it takes is the proper firmware to unlock the others! My old graphics card does that!
Just an fyi, your i3 is a dual core cpu with 4 threads available. So in a sense, your terminal is 100% wrong about everything ~

Thanks a lot. This app showed me 2 cores. One in grey color most of the time and another one active.
well, your i3" with four cores" actually only has two , and your note with one core actually has two.
If you want an 8 core Note i can make an app that will tell you you have them.. you wont of course, but if it makes you feel better...lol

Actually there are AMD Athlons that can Core Unlock, but perhaps you were talking about exynos processors
Imagine if someone released a app in the Play Store that will turn your "Dual Core Smart Phone" into a "Quad Core Smartphone"? Charge $19.99 and that developer would be rich in no time.
You dont even need to be rooted!! Works on all smartphones! HAHA

No. There are also single core variants. Korea has one, and I think South Africa.

Your Core i3 is dual core in the first place. It doesnt have 4 cores. What you see is 2 physical cores and the other two are just Intel's HyperThreading technology built into each core. Hence, theoritically you only have two physical cores supported by HyperThreading on each core. But most Operating System shows 4 cores, even Windows shows 4 CPUS.
Check out an old Pentium 4 CPU with HT technology where it all began. Under Windows or most desktop OSes, it will report 2 cores.
The Core i3 was initially and even to some extend today is considered to be a rebrand of the Core 2 Duo Processors and they are hence strictly dual core.
Core i5 is more of a mainstream processor available in both dual core and quad core variants.
A quadcore Intel processor would show 8CPUS under most desktop OSes, 4 being actual cores and 4 HyperThreading.
About the Note showing only one core, most multicore processors are built to use the cores on demand and to keep switching cores on or off as per needs. This is what you see.
Finally which platform are you running on the Note? Gingerbread isn't designed to efficiently utilize multicore processors. This has been fixed in ICS.
Just bought a Samsung Galaxy S4 internatiional version with Exynos 5 a few days back.
According to the SYSTEM TUNER App my SGS 4 is using ARM Cortex-A7 core whether i run cpu demanding apps like large games or i do low cpu demanding tasks like web browsing.
Help..!!!
if it has lcd instead amoled, its possible that a7 is only used
deleted
ok is there any aap by which I can see which core is being used

Lol do you really think that a quad arm a7 would score the high numbers you see in benchmarks? System tuner is not optimized to check for other cores as well I'm just guessing here

Hi I currently have an S3 i9300 and my company requires me to install MobileIron app and encrypt the whole phone; I find this slows down my phone considerably and often times I need to wait almost a minute for my app drawer to display my apps or some 20 seconds for camera to start.
Don't know if my experience with the S3 i9300 is only because of encryption app or also my processor-ram specs combination is not powerful enough to get a smooth experience.
So I'm looking to upgrade to an S4 but I don't know which version should I get based on which should be the faster one?
Should I get the 1.9GHz Qualcomm Snapdragon 600 quad-core processor or a 1.6GHz Exynos Octa-core processor?

Octa core variant is marginally faster but does not support 4g
Snapdragon Is little slow compare to Octa core but support 4g
u can choose as per ur need
Both are good device
the i9500 is faster even though it is really a quad core phone and only 4 cores can be activated at the same time. but I've seen somewhere that Samsung said with android 5 update the phone will be a real octa core and all eight cores can be used simultaneously.
The change to a i9500/9505 for you will be very good because the s3 I9300 only has 1gig of ram compared to the i9500/i9505 that have new processors and 2gigs of ram. That extra ram will definitely make a difference.

What are you saying, Android 5 doesn't even exist. Also the Exynos 5410 won't allow all 8 cores only the exynos 5420 can which is only in the Note 3
So based on what you said, I could even consider the Note3 which has 3gigs of ram and expect even better smoother performance? Saying I wouldn't mind the extra real state needs if I could realistically expect a noticeable improvement over currently described S3 conditions...

If u can go for the note 3 and u don't mind it's size ... go for the note 3 and never look back ... but i suggest u wait if you can ofc for about a month to see how the s800 against the 5420 exynos compares ... it not so much about the ram except if you are a really heavy multitasker but the cpu and gpu which we know for sure that in the snapdragon case it's a considerable improvement especially in the gpu department and we ve yet to see how the new exynos chipset will compare to it's older sibling ...

This is what I'm talking about. And for now note 3 is not octa core either.
am wondering if there is a difference between both version i watched some reviews of both devices and dun know if there is a noticeable difference
so dear users what do you think
and i have a question about bench mark tests
results are exactly the same but there is something important i wanna know
does the n9000 use 8 cores or 4 cores in test ?
because of it uses 8 cores in test and normal use of course uses 4 then samsung is cheating us . i know many ppl know but its first time for me to use octa core handset and wanted to know the difference
N9000 is 4 core and n9005 has 4 cores as well
But n9005 is fastest in benchmark and graphics...n9000 is very less dev support..go for n9005

n9000 is eight core one but mainly use quad cores only
i already have the n9000 so am asking
if anyone tried or could help
It can't use all 8 cores at the same time.

I have N9005. Is it possible to underclock its CPU and reduce its battery consumption?
I don't play games with it, therefore don't need the full potential.

it's possible by root
but.. the current setting of ondemand is quite good, and the most freq used is 1.3ghz.. so.. sysfs of ondemand governor are good
for others
exynos is ALWAYS the best since it always have 4 working logical cores witch kernel could use everytime.. so.. no hotplug lag as n9005 has with mpdecision script (qualcomm's script witch chose when turn on other cores.. and it's too slow)
Anyone knows why all apps i downloaded (cpu-z, monitor cpu, setcpu) only show max mhz at 1300?
i have a sm-g900h with arm15 cortex r2p3 , i understand that is an octa core with 4 cores at 2.1 ghz and 4 at 1.5
It is a phone problem or all these app don´t support the system?

It's likely most app do no "fully" support this new octa-core. I would suspect they only show the little CPU 4 cores @ 1.5GHz, however seeing 1.3GHz as the max is weird. In S4 octa-core, the max frequencies was used by both CPUs and frequencies below 600Mhz where meant to be used by little core (600Mhz being 1.2GHz on the little CPU, 700Mhz being exactly that on the big CPU), so there might be some similar tricks on the new S5. This would mean the kernel would only show 4 cores at any point in time.
Have you tried Android Tuner, it can adapt to any number of cores automatically (a little down arrow allows to switch to multi-core control) ? If you try it, can you post a screenshot here? I intend to buy the Galaxy S5 with 8 cores for testing purposes, so I'd be interested by first-hand screenshots, if any. You can check and post screenshots of the main CPU tab and also the Times tab which will show available cores timings for each frequencies.
