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.

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.

Hi. I have purchased 8.4" tab pro. Love it. It has good natural screen and is fast. But then I saw online the tab s. Is the screen worth the extra money and is the battery life much better? I am also concerned of the small bezels. Where should I hold it without touching the screen
In my opinion (which I'm quite fond of) the Tab S is worth the extra money.
If I already had a Tab Pro 8.4 that would be hard to say.
The bezels are slightly (mm's) slimmer on the Tab S from Tab Pro. If you were fine with the Tab Pro you shouldn't be a lot worse off with the Tab S.
I just returned my Tab Pro and picked up the Tab S. I recommend the 10.5 model just because you can read websites in portrait easier.
I was worried the amoled screen would be too much but it's great and I love the blacker text.

So did I. Went from 8.4 pro to the 10.5 S. So far I am very happy that I did.
The Tab Pro 8.4" is a quadcore, whereas the Tab S 8.4 is a octacore. So Tab S in this case would be far superior, plus the ultra power saving mode, finger print lock, and Super AMOLED screen is way better too on the "S" series for the 8.4" Tab comparisons.

Debatable which processor is faster. Really depends on what you're doing with it. I had a chance to see them both side by side and the SAMOLED screen on the Tab S looked better to my eye, but again that's subjective. IMHO, it comes down to price. They were running the Tab Pro 8.4 for $249 last week. At that price, the Tab S just isn't worth it. That said, I walked out today with a Tab S that was a return from a customer who got the wrong color. Box was unopened, but the guy gave me a decent discount because there was a big sticker that had been ripped off the side of it. Box looked pretty rough, but the contents were untouched.

It's not superior I wish they'd put the snap 801 instead of the exynos chip as only four cores can work at a time. Unless they can find a way to unlock. Plus it may take longer to root or get custom roms. I had the tab pro and a root was out in a couple of days.

The WiFi only variants of the Galaxy Tab S all feature Samsung’s own Exynos 5 Octa (5420). Internally we’re dealing with four ARM Cortex A15s and four ARM Cortex A7s in a big.LITTLE configuration, with a maximum of four cores of the same type being active at any given moment. The Cortex A7 cluster can run at up to 1.3GHz while the Cortex A15 cluster maxes out at 1.9GHz.

I was under the assumption that the Exynos 5420 didn't have HMP enabled. Samsung released a vague statement in the past saying that they could update the kernel on devices running the 5420 so that HMP works, but I'm not sure if anything came from it. Of course, I could be totally wrong and Samsung got HMP working on these devices.
According to an Anandtech article (I know, sorry) on the newer 5422 processor back in February:
"The 5422 supports HMP (Heterogeneous Multi-Processing), and Samsung LSI tells us that unlike the 5420 we may actually see this one used with HMP enabled. HMP refers to the ability for the OS to use and schedule threads on all 8 cores at the same time, putting those threads with low performance requirements on the little cores and high performance threads on the big cores."

Any links to back that up? Everything I read says no 5420 has HMP turned on and that the Tab S only uses one set or the other depending on performance needs, never both together.

Hmm, you're right. I really should've checked more sources. One minute Google research doesn't get you really far. In that same article Anandtech's chart lists the max number of active cores for the 5420 as: 4 (?) .
Do what I did. Speak to technical support at Samsung.
I'll go one step further. What we do know is that the 5420 in the Tab S is scoring 35,000+ in Antutu...
It seems that our Note 2014 versions usually score about 32,000+, So that lead me to suspect that the newer Galaxy Tab S 5420 was HMP enabled due to the higher Antutu scores.*
And again, had confirmed when I spoke with Samsung directly.

My note pro 8.4 with snapdragon 800 scores 35000 as well, I wouldn't call that proof on HMP. When you read the specs for the 5422 they state first chipset with HMP. Color me dubious that it's been turned on for the 5420. I hope I'm wrong
You're comparing apples to oranges. We have an AMOLED screen using the Exynos Octa 5. The Snapdragon on an inferiorly smaller screen (without AMOLED) will naturally get better CPU/GPU scores on Antutu

The Pro 8.4 has the same resolution8.4 1600 x 2560 display) minus the amoled, and 1gb less RAM, same Android version.
I do agree any Antutu score is meaningless to prove HMP or not.

You left out the smaller screen. Apples and Oranges.
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:

Here is a post from odroid

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.
Over the years I have switched rom's many times.
Now I am back on stock 5.1.1
I use app2sd pro to help improve performance and it was in the app I noticed that it shows the device only has four cores.
So I downloaded cpu id and antutu and they all show four cores.
I am wondering why. Did I install the wrong stock rom even though it was labelled as Australia XSA?
Something else?
Strange.....
Edit: the p600 should have an octa-core
So how can one verify that it is octa-core?

You can't , it is first gen big.little SoC, meaning that you can only use 4 at a time. It is the SoC immediately after this that allowed for all 8 to be used synchronously.
There was a guy some time back that tried to enable all 8 cores working in synergy. Eventually he gave up IIRC , I just can't recall the reason.
IMO the reason that Samsung did not allow for it was that the SoC would throttle due to high temps if you were to enable all 8 at once leading to actually lower performance. So they simply disabled it. After a node shrink they finally managed to do it without thermal throttling, so the first phone that had it in a useful manner was the Note 4 (we use Note 3 tech). IIRC S5 had the feature as well however it throttle to hell and back, so it was not very useful there (hence why Note 4 was the first to use 8 cores syncronously in a useful manner)

So when you throttle the cpu, does it work on the slower or faster quad core?
