Hi everyone,
Theoretically, I was just wondering the Galaxy Note II would be more better in both battery efficient and boost in CPU performance if it was using the Quad core snapdragon (krait) than to the Quad core (A9) exynos.
I was wondering why Samsung Company chose their own chips (A9) instead of a more advance chips (Krait).
Is it because Quad core Snapdragon chips are low in supply due to high demands from other rival smartphone manufacturers?
its sad to know they are not releasing a Snapdragon Quad core variant for their new flagship phablet.
Initially, i was disappointed that the US variant of Galaxy S III has a dual core Snapdragon chips (Krait) compare to the international version of a Quadcore Exynos (A9) chips, but now I'm disappointed that they are not releasing a Quad core Snapdragon chips (Krait) variant of Galaxy Note II.
what are your thoughts, guys.
Never ever liked the snapdragon processors... why? Cause after a long term use they slowly die down like a kid running for 15 minutes straight slowly slows down during the process then eventually cant take it anymore and just quit
I'm a consultant... ask me anything... I'll run away.

pls share your website source that supports your answer that snapdragon slows downs
Gnex has 1.2ghz dual core cortex a9 ti omap 1gb ram Powervrsgx540, 720p hd display
is the specs of the Gnex better than 1.2ghz quad core cortex a7 mediatek 1gb ram powervrsgx544,720p display
From the benchmark perspective, no it's not. Dual A9's usually equal to quad A7's in CPU power, while SGX544MP1 is obviously superior to SGX540. However, the bloatware those small manufacturers tend to put in those MTK devices will obviously slow the phone down. Words around the internet also say that although MT6589 is a quad A7 CPU, only 2 cores are used per normal task.
I suppose you're gonna buy a device - don't buy MTKs, there's usually no development for them, they may never get future Android upgrades even via flashing (because there's no custom ROM at all), meaning that your phone could be dead on arrival. Personal opinion so feel free to oppose.

Ive gotten apps that can over clock the cores, but it's only the 4 SMALL cores which clock at 1.3 GHZ and can over clock into 1.9 GHZ but I don't need that since the Exynos 5 Octa has 4 OTHER cores that clock at 1.9GHZ. The Dolphin emulator doesn't use the 1.9GHZ cores. When I over clock there 1.3GHZ to 1.9GHZ while playing Super Smash Bros Melee, it runs just as good as the Note 3 does, which is 2.3GHZ SnapDragon. If I were to use AND over clock the 1.9GHZ cores, I may be able to run that and also other graphic intense games almost perfectly. Help please.

Overclocking was attempted with the Bindroid Kernel but it would not stick. As for it running better on the Note 3, you are pushing a lot fewer pixels on the Note 3 (1200x1980) versus Note 2014 (2560x1600)

what's a bindroid kernel lol and well then shouldn't that mean that it should be harder to run on the tablet??? and also if I were to over clock the bigger cores and over clock the gpu, which so far the apps that over clock gpu's are only for Snapdargon, then it would run better than any device on the market.
Also, I found this: "The core switching is controlled by a firmware layer that sits in between the software and the chip itself. Operating systems can be tweaked to better support big.LITTLE's particular arrangement of cores, but any OS that supports power state switching for CPUs (any mainstream operating system from the last decade or so) can take advantage of big.LITTLE without any additional changes."

Though this is for the galaxy s4, it should be the architecture as the note 10.1 2014. But is it possible to tweak that firmware or even MANUALLY activate the 4 stronger cores at will???

You may want to do some more research before you do anything. Most aspects of the CPU or GPU are handled by the kernel. The only way you can overclock any device is with a custom kernel that has the higher frequencies in the tables. DutchDanny tried to get overclocking working but it did not work. You can however underclock most any device since it has all the lower frequencies listed. If we wanted to enable Big Little on the Note 2014 we would need Samsung to release source code enabling it. Which I am sure they will not do. Again the Big Little is kernel dependent. The Android OS is not the problem Samsung is the problem. Do a search there is a very good thread about the 8 core thing.

The Exynos 5 is fully capable but Samsung has never said they would update the Note 2014 to enable it.

I got the Note 2014 the day it came out and I check all kinds of news/forums everyday. I have seen nothing where they stated they would update any current devices with big.LITTLE. They have stated by the end of the year they would release new devices with big.LITTLE implemented. I would guess the first ones would be the 6 core midrange processor due to heat and power usage. You can get a lot more information from this thread in the main section.

The galaxy tab s products that are available to me have an octa-core processor, with the high speed cores being 1.9ghz. I can't really understand why Samsung chose to use that instead of a 2.3ghz quad-core like in the tab pro.
See Wikipedia for an explanation of the concept: http://en.m.wikipedia.org/wiki/ARM_...multi-processing_.28global_task_scheduling.29
Because the Exynos 5 Octa-core is the one processor that Samsung has to be able to compete with Snapdragon 800, and is cheaper to implement since it's their own processor. I don't buy the Octa-core hype, I'd be happier with the Snapdragon 800 honestly like on the Tab PRO 8.4.
The question is:
Does TAB S use the 8 cores at the same time?
It seams it does NOT, little cores are only used when low power is required..
So performance wise, this CPU is slower than SD 800

And yet I am getting 35,300 on Antutu using Shaheers t800 rom which is higher than any other current tablet or phone. (Shaheer's rom should go out of beta today - don't flash until final has been posted).
The Tab Pro 8.4 Antutu is 32,806.
I CANT PLAY NOVA 3 with exynos !
AND GAMING IS NOT SO SMOOTH ! STILL A BIT LAGGY
I can see the argument that you don't always need full power, thus the four slow cores, but since all cores can't run at once, it seems a cheat to have 1.9ghz as the top speed for the faster four cores. Since, or at least I assume, cores step up and down as needed, it seems to me a snapdragon 800 or higher at 2.3ghz or higher would have been just fine. I mean, if you are going to put in 3gb of RAM, then you should put in a great cpu also and not pretend less (1.9ghz) is a better contribution to what is supposed to be a premium tablet.
And yet I don't think samsung is doing enough to utilizing this hardware capability. In theory it should run at least 4x faster and 6x more effecient then the snap dragon and apple current A8 chip. It has failed to outshine the competitors because samsung software department sucks. Samsung hardware is still great though.

Blame the developer for not making it compatible. Tegra powered Htc one x is incompatible too so not sure that is exynos issue..
i wish my t805 had Full HD screen resolution :cyclops:
Funny. Was just browsing the web a bit on my i5 ultrabook and it occurred to me that the browser on my Tab S is actually faster. If gaming is your primary thing, I'd buy the Nvidia Shield, not the Tab S. This tablet is designed for eye candy media consumption (internet and video) not for gaming enthusiasts. Try running your PC video card at 2560 x 1600 on ultra and see what you get.
i had heard from a Samsung rep i actually enjoy talking to that Sammy had just figured the all cores at once and we should see updates that turn that feature on. when this will happen who knows. i also did not ask him for a link and now cant find that info on the web so when i see him again soon i will get more info.
i would assume (insert you know what that means) that when/if this happens the full power of this setup would greatly improve?
anyway i have had my Tab S running snappy for me and no complaints at this time
You cannot compare the clock speeds from two different processors. For instance, you can't compare the 1.9GHz quad-core of the Exynos to the 2.3GHz quad-core of the Snapdragon 800. This doesn't mean anything. If you compare the clock speed of two Snapdragon chips, that's ok, or if you compare the clock speed of two Exynos chips, then that's ok too. Comparing the clock speed of an Intel chip against the clock speed of an AMD chip, is the same as comparing the clock speed of an Exynos chip to the clock speed of a Snapdragon chip.
The Exynos chip in this tablet has been shown to compete very well/close with the Snapdragon on every level except GPU. The Mali GPU in this chip just doesn't match the Adreno GPU from the Snapdragon. However, the RAM is faster in the Exynos than the Snapdragon.
That said, I am a fan of the Snapdragon chip, of course. I was holding off to see if the LTE variant of this tablet would have the Snapdragon 800, but instead they shipped with an Intel LTE modem. Besides apps/games not being optimized for Exynos, I am fairly satisfied with my purchase. I'm just anxious to get CyanogenMod(or any other AOSP ROM installed on it).

Could also mean increased battery consumption,don't know. Overall I am satisfied with this Tab including battery life.
There are 3 different performace results:
a) what Exynos 520 does achieve in practice now, measured bei some benchmarks and real world performance (<= Snapdragon 800)
b) what it could do theoretically - but will never happen due to driver and scheduler etc issues (>> Snapdragon)
c) what it will do some day in near future on an optimized ROM (somewhere in between?)
Fortunately the Exynos 5420 does support all 8 cores in parallel, see here:

Wish I knew how. Probably a linux thing. ...
If it is possible to implement in today's existing source, I'm sure @AndreiLux would know about it ?

I've found a few articles saying it should support it, then a couple Deva saying they had to goto the 5422 for a working implementation of HMP.
Here is a post from odroid
http://forum.odroid.com/viewtopic.php?f=97&t=5651
That's weird. The (newer) 5422 supports HMP but not 3gb RAM.
Can Exynos 5 OCTA 5420 use all 8 cores at same time?
How is Samsung Galaxy Tab S SM-T700 performance compared to Samsung Galaxy Tab S SM-T705( with Qualcomm Snapdragon 800)?
The Exynos cpu performs admirably against my htc one m8 snapdragon cpu and ranks highly with other top performing cpu's.
Even better with Skyhigh kernel.
Worth mentioning these Exynos units suck the battery dry much faster than the Qualcomm S800 without delivering more performance.

According to the wikipedia article, the Linux kernel does have a scheduler mode that allows to use all cores or switch between them as needed. I don't know if the Samsung stock kernel or others actually use that mode.
One important issue is that you should not be carried away with the idea that having more cores is always better for performance. It takes a lot of work to write software that can actually load four or eight cores. Moreover, a lot of algorithms are still bottle-necked by one core and there is no way to change that. As a result, a typical PC with a quad core Intel i5 CPU is usually faster than a PC with a six or eight core AMD CPU, thanks to intel's much better individual core performance. This truth is even more relevant on tablets, which are effectively single-user machines, usually running only one big application at a time. I wouldn't lose a minute of my sleep over having only two working cores instead of four or eight.
