Valid point. The longevity of the s4 looks very promising.
[Galaxy S 4 General] Kremata:
Ok but then if the ROM becomes demanding enough to run on the A15 all the time your battery life will drastically go down. Specialy when we know how 2 years old batteries behave.
[Galaxy S 4 General] PLUG313:
you can always get one of those super extended batteries.

thank you samsung for still including a removable back cover!
[Galaxy S 4 General] Kremata:
That would solve the 2 years old battery problem but not the A15 running all the time. I hope I'm wrong on this one. Maybe AndreiLux can shed a light on this.
[Galaxy S 4 General] DynamicN:
I don't think the A15 would run all the time because that would be a sheer powerhouse with zero economical focus. Maybe a combination of 50/50 would be a good balance but then again it all depends on how the phone is used from one person to the next.

Re: [Info] Exynos Octa and why you need to stop the drama about the 8 cores

That would be a wrong direction for android, even if it happens I read somewhere about core sharing where the rom can utilize all a7 cores and can utilize one or two a15 cores depending on th of need.

Average Joe here, just read the thread, thanks guys good read, ok here's my user profile, in the UK 3 will give us lte for no cost increase also they give 42mb hspa+, my n4 gets up to 20 Mbps down but averages 8/12 Mbps which is what iirc ee give as their lte, is this correct, I play games just got mc4 for 69p but I'm not that bothered by battery as I'm literally never more than as yard from a power source, SO WHICH MODEL DO I WANT.

Sorry for shouting it was aimed at Sammy for this confusing launch of a phone I've been looking forward to for months, all the talk of the clever exynos and applesque GPU then wham if you want lte its the s600 and adreno for you, so i read up and think cool no worries that's still good kit.

I'm now left wondering and waiting to see which phone best meets my needs and whether the exynos will actually get lte in September or so.

Well I've successfully lowered the tone of the thread but I bet I represent a huge amount of the potential buyers of the S4.

Re: [Info] Exynos Octa and why you need to stop the drama about the 8 cores

[Galaxy S 4 General] gTen:
This video should answer most of your questions:

http://www.viddler.com/v/af9c9dba

As you can see, it is mix and matching cores depending on needs. The A7 cores are about same processing power as A8 cores but use up to 5x less power. So when your navigating the GUI it will most likely use A7 cores and the GPU (hardware acceleration). Also the A7 cores will be used when watching a video (due to most processing being done by ARM Neon hardware decoding). But when you start launching apps and web browser. it will use both the A7 cores with spikes of A15. And heavy and intensive applications will use just the A15.

Exynos 5 Octa confirmed to have LTE, lack of availability reportedly due to supply shortages:

[Galaxy S 4 General] pack21:
lol, now we will have subject matter for next few weeks.

After all we will have Exynos LTE or not?
[Galaxy S 4 General] SmilerOnline:
TBH I have said from the beginning that I'd choose the exynos over the snapdragon any day, simply because I want that big.LITTLE technology that the exynos 5 octa uses

And with that the exynos will give me better performance and battery life than my current S2 offers :)

4G LTE isn't too important to me (but it is a bonus), since most of the time I use my device for things that don't require network access, although when I do need network access I'm usually connected to Wi-Fi anyway.

So if I need to wait a few more weeks for the exynos variant I will... if I can't get the exynos variant then I just wont upgrade until there are big.LITTLE devices available on the market.
[Galaxy S 4 General] PLUG313:
the only reason I'm getting the S4 is because it's the best phone available at the moment, and I don't have one. if I did, I would gladly wait for the Note III because I'm sure it will be so much better and will have everything worked out

Re: [Info] Exynos Octa and why you need to stop the drama about the 8 cores

Okay, can someone please explain to me how over clocking will work on this chip?

On normal chips, if I set the clock speed to 1024/1612 MHz, the cores will change clock between these two values.

However, on the exynos octa chip, there are two different clusters with different clock speeds. So how would it work? I don't see a way to overclock and undervolt efficiently without a GUI
[Galaxy S 4 General] AndreiLux:
You have two sets of min/max frequencies and two sets of voltages for each core, and a fifth controllable which dictates the frequency at which the IKS switches from the A7 to the A15s.

Re: [Info] Exynos Octa and why you need to stop the drama about the 8 cores

Exynos always had more power and efficient battery hence superior to snapdragon. Recent reviews revealed that octa exynos will have 10% more powerful and 2 and half more hours of video watching.

In Youtube vids on the S4 (non final software of course) touchwiz seems to lag even navigating around the UI. It's actually quite bothersome to me because my SGS and SGS II did the same thing.

When you say 800 MHz, is that the base clock, so 1600 MHz DDR?

---------- Post added at 03:09 PM ---------- Previous post was at 02:54 PM ----------

And what was the power draw of T4 when pulling those figures???, if T4 was so awesome at the constrained power figures required for a tablet,let alone a smartphone we'd be in Tegra 4 design win heaven. ARM have developed big.LITTLE to mitigate against the worst aspects of the A15, whilst trying to leave as much of the peak performance on the table as possible.

A15 definitely has higher IPC than Snapdragon 600, but higher peak power usage. Snapdragon 800 is the A15 rival, lets see the result of methodical testing at equivalent power profiles before passing judgement...

[Galaxy S 4 General] sorg:
I don't suggest to buy Korean version. They have many "bookmarks" in their firmware to tie with Korean providers, like limited SMS length. Roaming also may work incorrectly. And it's hard to fix by custom firmware because hardware is different. You cannot flash firmware from international version. Even hard to use libraries from international version - you have to patch them usually (if you know how).

I had SGSII HD, and i'm using SGSIII SHV-E210K, so i know what i'm talking about. While i could successfully fix SMS issue on SHV-E210K (And i couldn't fully fix it on SGSII HD), i won't go to Korean version unless spec is greatly outperform international version.

Since Korean SGSIII has different thickness and completely different back cover retention, i have problem with accessories. Battery is different too.

So, think very carefully before go with Korean version!

I'm sure that I9500 will be easy to overclock to 1.8Ghz (if stock will be 1.6).
[Galaxy S 4 General] AndreiLux:
There is confusion out there between how the maximum frequency is reported. That 1800MHz in AnTuTu represents the highest entry in the frequency table, however this does not represent the highest running policy of the CPU. You can check this if you have an overclocked kernel, it will show the maximum available frequency, but not the actual running maximum. Quadrant should be one who actually reads out the maximum policy correctly most of the time in its "Current" display.

People should wait for some reviewers with the least bit of technical knowledge on the matter, or even until users actually have it in their hands, before they consider it a definite confirmation. This includes the Korean version too.
[Galaxy S 4 General] mw86:
Thank you all! I'll keep watching this thread and looking for more real evidence but based on these posts I will set my sights on the gt-i9500 based on ease of use from carrier to carrier and proper function of roam and all other mentioned downfalls of buying a Korean version for US or well non Korean local for planned usage of the phone.

[Galaxy S 4 General] i9100g user:
Looks like A15s are clocked at 1800 mhz and this glbenchmark was conducted on a unit which was not running the final software.

triangle throughoutput(offscreen) and triangle throughoutput fragment lit (offscreen) are lower than iphone 5 (which is clocked lower and has same unit setup as sgx544 and same no of cores)

,so i think some software optimisation is lacking here.
[Galaxy S 4 General] yahyoh:
for real dude it been discussed like 10000 times

the A15 cores are clocked @ 1.6 , the damn apps reading the max CPU clock from the frequency table not the current max policy :rolleyes:

same on my N2 i'm setting my max CPU @1.6 :silly::silly:

maybe Samsung will remove the 1.8 clock from the frequency table with the final software :confused:

edit : if the final software will stay like this so we can OC with stock kernel :p ( all u need root with some CPU control app :D )
[Galaxy S 4 General] i9100g user:
I tried 2 kernels on s3.

When on boeffla kernel (which supports upto 1.6ghz)

It shows max as 1.6ghz

And when on perseus kernel which supports upto 1.8ghz

It shows max as 1.8ghz

So I think that max frequency depends on kernel.

Try stock kernel, rom (Without root) and we might get our answer.(assuming s4 is not rooted in that glbenchmark)

Note that the current frequency is listed as 1300 MHz, which means that the Benchmark is running on the A15 cluster, if the max clock of 1.2 GHz for the A7 is correct. I would have thought that the A7 would have been enough for such a GPU focused benchmark.

A lingering question is how the 5410 responds to touch inputs, as Jelly Bean uses a CPU boost, whenever a touch event is triggered to increase smoothness, but does it trigger the A15s???
[Galaxy S 4 General] AndreiLux:
It doesn't mean anything at all. That current frequency is the CPU frequency at the time you open up the information page of any application, it's relatively useless.

Also the IKS doesn't map things directly. At frequencies like 1000MHz you won't know which core is online simply through frequency. The frequencies reported are virtual ones, and hopefully normalized to the A15 performances. ARM did it the other way round on their test chips and reported frequencies normalized on the A7 cores which is stupid as things went up to 2.4GHz reported even though max was 1.2GHz on the A15.

It's senseless to discuss it until we actually will see the source code, you will not be able to come to conclusions from any application not designed with the new frequency planes in mind.

[Galaxy S 4 General] AayushDhuria:
That is kernel source code. For Exynos 4 based devices, Kernel source code != Chipset driver source code. Like qualcomm has codeaurora and omap has (Or had?) omapzoom. Kernel source code is needed for custom kernels, for eg the one Andrei develops, while the chipset source code is needed for working of AOSP ROMs. Samsung doesn't even provide working blobs, they're mostly broken (Entropy's words, not mine). *I might be wrong, Andrei's the expert here* :)
