Database Info

let me see if i understand this correctly

so the g2x has a duel core processer that gingerbread does not support? so i'm only useing one. and ics does support duel cores. the only way i'll get ics is to root my phone and wait for on of the devs to get an ics rom working on the the g2x. thanks in advance

In a nutshell

It controls the two CPUs as one, it doesn't just use one. The rest I believe is correct.

I think even rooting the phone and waiting for ICS from here will still not use the dual core properly as it will not have the Nvidia drivers till after it is released by LG.

WOW, thats pretty weak.

It's not that you're only using one core, it's that the two cores cannot function independently. They both focus on the same task and clock at the same speed, all the time. So you do notice an increase in performance above, say, a Nexus S, but it's not as good as it could be.
This is not a limitation of Gingerbread per say, but more a limitation of the drivers. Since nVidia does not release their driver source, we have to wait for them to provide better ones, which in all likelihood will never happen.

Two processors, one task
Due to resource sharing (cache, memory, mass storage, I/O), it is VERY hard to get two processors to work on one task. Some manager/executive would have to partition or parallelize the work between the two processors. And most tasks have many serial operations - what mechanism is going to serialize the tasks amongst two processors? I have yet to see a linux kernel expert on these forums declare Froyo or GB his a linux kernel that supports this.
The procs have dedicated L1 cache, and a shared L2 cache - stale cache blocks (aka cache miss) would be a nightmare if two procs were working on the same task - it would actually be slower.
Symmetric multi-core is made for multiple tasks or threads, not trying to parallelize a single task. I thought this was discussed in another thread...

thanks for the forward
edit:so i was reading the forwarded link and i ran in another like
http://api.viglink.com/api/click?fo...alcore-1015/&jsonp=vglnk_jsonp_13219228920753
and in this link it says the tegra 2 didn't use the asynchronous duel cores because nividia says it loses 10-15% performance. so i'm led to believe there not working independently. unless i'm misunderstanding.

Both cores are running just not as efficiently as they could with multi-threading. ICS will multi-thread and properly use the dual cores.

Thread scheduler
So does anyone know what mechanism handles thread scheduling? I guess it'd have to be at the Android layer... And I thought that was introduced in 3.0?

Don't bother with battery comparisons on the i9500, the phone is unfinished.

So I got my i9500 and already did some foolery with it.
Fine device, but I hate the raised lip around the screen edge. Something I definitely did not miss on the S3 and something very annoying.
Other than that small design critique:
THE ****ING PHONE ISN'T RUNNING FINAL FIRMWARE!
Basically the CPU is running on the cluster migration driver, meaning it switches all four cores from the LITTLE to the big cluster, as opposed to the core migration driver who does this in an individual core-pair manner.
You can pretty much throw all battery comparisons out of the window: it's completely unfinished and unoptimal.
I already compiled the kernel and flashed it without the cluster migration tidbit, but the phone won't boot. So yea. Current sources also useless.
Cleverly enough: you can't really distinguish between the two drivers apart from one manner: if /sys/devices/system/cpu/cpufreq/iks-cpufreq/max_eagle_count is present, you're running an IKS driver. If it's not, then you're running the sub-optimal IKCS driver.
So yea. We'll see what Samsung does about this, currently the advantages of big.LITTLE are pretty much unused.
Another nail in the coffin on how rushed and unprepared this phone has been.

Wow, this is seriously turning out to be a fiasco.

This is EXACTLY why at the end I don't care for technical details about socs but was rather waiting for real world usage first. As much I wanted to agree with Andrei Lux on how intelligent BigLittle is, I sort of felt that it wont be same at the end.
Question is now: Is this possible to fix in the near future?? So that maybe buying the Exynos will be beneficial if the devs take over. I wont bet on Samsung introducing mind-blowing improvements in that department in upcoming firmwares

The code other driver is there in the kernel, it's just not used. No idea. It's not like we need Samsung for it: I already talked to a developer at Linaro about some incomplete switcher code that's being currently getting the green-light to be made public. But who knows how long that will take.
Whatever the case, I gather that they can't just let it be in the current state.

Any way to just disable cortex a15 altogether yet just to see how well cortex a7 will perform in simple texting, browsing, calling and to see what the battery life will be like on that?? (cause cortex a7 only uses like 200 something mw as opposed to 1000mw for snapdragon). I know u wont be able to game. How often does Cortex A15 hits in? cause I would suspect a much worse battery life with incomplete drivers doing the switching if its very often on. But PocketNow reports very similar battery results to snapdragon variant which I find odd

Use any app to limit the CPU frequency to 600MHz. That'll limit it to the A7 cores running to 1200MHz. Basically you can just use CPU-Spy. Everything <= 600 are A7's mapped at half frequency, everything above it are A15's at 1:1 frequency.
As for PocketNow: irrelevant. The difference is what could be instead of what is, the Snapdragon doesn't play a role in the discussion here.

WOW , thats sucks
Samsung was too rushed and ruined it :/

Hey thanks, but I don't have the S4 to test it with since i'm still debating on which to get. I live in Canada and so the only version here which I can get a lot cheaper on a contract is LTE snapdragon, but I wont mind getting the Exynos since it got potential. Besides 16GB internal isn't enough for me. So that's why asking if u seen any improvements in battery when only cortex a7 ran? If a7 doesn't do much in power consumption, then no point spending 800 bucks and loosing LTE altogether...

that's not what samsung exynos advertised..
http://www.youtube.com/watch?v=U6UNODPHAHo

Is it possible that we're having a simpler Exynos 5 system technically closer to Exynis 5 Quad (plus 4 A7 cores) than a real seamless Octa-core system? It was strange reading that "Octa-core manufacturing starts in Q2" (April-June) then see Octa-core versions hitting reviewers early April, that's way too low time frame. Maybe this is a 1st-gen 5410. In any case, performance and current-state battery life beats the Snapdragon version, even if only just.

Is it a specific hardware limitation? Something that Samsung specificly did in GS4 (I9500) ?
Because this can't be a generic exynos octa limitation. It makes no sense... Unless everything we've read from Samsung and ARM about exynos octa, are completely misleading...

A hardware limitation..? They advertised the functionality and to then release a device without it, is just plain stupid. Hopefully it is a just a kernel issue and can be resolved quickly.

Now what is this all about? Is this a very serious issue?

So its either all A15s or all A7s?
so would the 'octa' really be a better choice than the S600? That should be powerful enough.. and the S600 is pretty power efficient too

What I understood is its either the full cluster of a7 or a15 is used/ functional based on the load, dynamically turning on one or two cores of a15 to work along with a7 may not be possible it seems.

I was always under the impression this was the intention of Samsung's particular implementation of it. I thought it was common knowledge that Samsung's version worked on a 4 or 4 (A15) or (A7) basis.
Maybe he was talking about the ability to change that.

[Discussion] GalaxyNoteIII -Exynos vs. Qualcomm

Hi
Discuss and Compare Note III Exynos vs. Qualcomm
General Performance
- Performance of Gaming
- Performance of (using another apps)
Battery Life
& etc.
Note III N9000 will brings real Octa-Core /Exynos 5 Octa 5420 (N9000)
It means u have 4+4 cores to work with true 3GB of RAM; it seems best thing for multi-taskers...
and it might get best cpu performance (highest benchmark) even with bad hardware calibration!
Adreno 330 N9005 (Snapdragon) & Mali-T628 MP6 N9000 (Exynos) are almost similar
both have OpenCL, OpenGL ES 3.0, Renderscript Compute and etc.
infact thr s no technical reasons to get which one is better
so in my opinion in depend on ROM how to use GPU
S-Lag
the famous lag in launcher of galaxy device (touch wiz) > not found anything about it yet
But it s depend on time when do heavy using. so nothing to compare
Battery and charge
both Snapdragon 800 & Exynos 5420 (little.BIG) have energy efficient feature but there s better energy usage in N9005 (Snapdragon800) related to this video, Watch and some another report.
(will update with more choice and result)
- - - - -

Qualcomm version wins hands down...maybe not in benchmarks but it will get cm for shure

These threads are pretty useless,we don't even have any information about real life performance of Exynos Note 3 and since it is certainly first soc of its own type ,we will have to see.
No offence to OP or any one

So if u didn't check them search it NOW and then discuss here
:good:

which version do you think it will have the most dev support?

Even though i live in India where we are going to get the exynos version, I'd prefer the snapdragon version. Im new here, but doesnt 1.3 and 1.9GHz seem less for a high end premium smartphone? Also Snapdragon will get cm for sure,

as u can check benchmarks of Octa version of Galaxy S4 u can realize that Octa-core of course has better performance than quad
the final quad-core antutu of note3 will be ~34,000 and octa will be 35,000 (at least)
:good:

Some of the things I value are stability and low heat. I'm experiencing possible stability issues with Nexus 7 (2013) based on Snapdragon S4 Pro/600 where on level 10 in Modern Combat 3 it's not only heating up the device making it very warm but the game is also exiting consistently when this happens. I don't have that issue with the Exynos based Note II so I'm leaning towards preferring the Exynos 5420 in the Note III. Btw, Exynos is fabbed by Samsung while Snapdragon is fabbed by TSMC. IMHO, Samsung fab is better.

Sammy will include HMP in their octacore processors through a software upgrade .so all samsung octacore devices will become true octacore devices
So guess which will have high performance? Real octacore exynos 5420 or sd800??

While a cool feature, I'm not sure how many CPU bottlenecks are going to be multithreaded to the point that adding the four slower cores will provide a substantial benefit. I also have concerns that with all eight cores running, heat throttling would kick in pretty quickly. My guess would be that, both in benchmarks and in real-world situations, the 800 is usually going to come out on top.

In HMP this is what really gonna happen:
Small processes like texting,calling , etc... low powered A7 cpu's will be switched
Big processes like gaming , Benchmarking , 1080p video capturing etc... both A7 and A15 cores will be combined together and throttle the device upto the max perfomance
So the device will be power efficient and we can clearly see the dominated benchmark scores and RLP over sd 800 (this would be pretty like the perfomance b/w a dual cored device and a quad cored device)

Going to buy S7. Is it worth it?

Hi. After a year of having my S5 mini I am done. It is old and using 2012 processor in 2016 is not a good idea. So I looked at the phones and I decided to buy S7(Exynos model) for a quite some time.
BY YOUR OWN EXPERIENCE, can you say:
Will it run 3D (like C-OPS) games on max graphics on 60FPS?(Or 60FPS at all?(with low graphics etc.))
What are the most common bugs/glitches/problems on it?
Are they that bad that you would recommend to avoid S7?
If the device is not good by your opinion, can you suggest a different one?
Is it worth the price?
Why do I ask these specific questions? Because I don't have enough money to change the phone every year or even earlier so I want to have high end device that would handle minimum 2 years.
P.S.(if it will help) I can pick it up at electronics shop in my country for 400 euro(discount!).
Sent from my SM-G800F using XDA-Developers mobile app

I think the phone is worth the price, but you also have the one plus 3.. s7 runs all games on max graphics easily.
Im in love with the phone and im sure that it will last few years
And.. I bought it one month ago and until now i had 0 bugs and errors.. non rooted btw

I found my s7 overheating at first but then I under clocked it a bit(STILL VERY FAST AND SMOOTH) and my issue was solved. You can also try coolify.

If you ask me, yes, it is worth buying if you have a 3 year old, slow smartphone, due for an upgrade and features like 'Better Low Light Photography' and 'Water Resistance'. The phone definitely looks promising enough and looks absolutely beautiful. Consider your pros and cons budget wise, but I think it's definitely worth the buy.

Those apps are all bull****, stay away from such stuff. The only way to lower heat is to lower performance, some apps might be able to underclock the CPU or change governor but those that claim to lower heat without root are just shady apps.
on topic: I bought the flat s7, exynos variant too and well, I'm not disappointed at all so far. Screen is amazing as expected, wifi/data speeds are top notch, battery is surprisingly good and most bloatware can easily be disabled now even without root thanks to this app: https://play.google.com/store/apps/details?id=com.ospolice.packagedisablerpro (careful with what you disable, some apps are obviously necessary for the phone to function and disabling them can result in features not working or even bootlops, make sure you know what it is you're disabling)
as for cons, well the price will always sting so there's that, it also seems like the GPU on the exynos variant is slightly weaker than the one in the snapdragon variant but I'm not a big gamer so I can't comment much on that and it can occasionally stutter a bit if you're performing certain tasks, like having multiple apps updating while gaming or right after you apply a new theme but those are special occasions where the CPU is obviously being stressed. Day to day usage, there's not much if any lag at all.

My Windows 8 PC x64 uses only 2GB when no apps are running. And my old Vista x32 used 900MB only! Even my S5 mini with Touchwiz when no apps are running uses 800MB or even lower. I even got 563MB RAM using only some time in its life. I don't know what the problem is but I think this is all Samsung's fault. Like why the hell they need to modify Android so much?! Just create a slightly modified Stock ROM with some additional apps like Smart Manager and Galaxy Apps and change to Samsung wallpapers and that's it.

You can't compare ram manager of Windows and Android systems, very different! In Android free ram is a wasted ram! So..... more stuff in ram....more quickly it opens app or background process, if the user needs more ram to open a hungry app the system will close other stuff to satisfy the user needs. Is this really important in the rom....ram manager! Samsung have to do a good job to give us a very tune and balance ram manager for the system running smoothly.

You are talking about Snapdragon(US) or Exynos(EU) variant? Because that's what I am going to buy because I don't live in US which is kinda sad.

Doesn't matter. Both run the same TW.

(Exynos)Games have less FPS

So I was playing a game Critical Ops and I invited my friend to play it (he plays on iPhone SE). Most of the time, phone gets 50-60fps with lag spikes every minute or so. But my friend doesn't experience anything like this; he gets 55-60 without any lag spikes. So I've began to wonder if my phone is bad. So we made AnTuTu Benchmark and GeekBench and results were similar (about 130K in AnTuTu and about 5500 multi-core score in GeekBench). After this, I went to supermarket because there was a shop with phones that you can try. So I tried playing with shop's S7 (G930X), and I saw that it was running as same as my friend's iPhone did (55-60 without lag spikes) in the same graphics settings. I installed cpu monitoring app on my phone to see what's happening and I saw that CPU wasn't maxed out. 2 or 3 (I think stronger cores) weren't working. So I thought that they are corrupted or sth. so I did a benchmark with monitoring on and I saw that only then all cores were working(didn't test the S7 that was on shop though). So what it can be? Do I need to root my phone or is the phone itself bad? Please help.

Actually I have exynos S7 G930F variant I use to get lock ups playing Bloons TD 5 but after clearing recents and leaving that game still running it fixed the issue and got full speed no lock ups try clear recents before running games (I'm on superman rom and super kernel with default settings)

Well I play BTD Battles(a little more intensive game than BTD5) and getting no problem, even in 30th round. I clear the recents and use Smart Manager widget to get some free ram before running a game.
I see you are rooted right? Do I really need to root my phone? It's only about 2 weeks old and I worried a little for the warranty but if there's no solution for without root then I will manage to make it at some point.
P.S. I think you are secured from this happening because you have a root and a custom rom and kernel so you can manage everything

Exynos G930F comes to a crawl at level 100+ on BTD5 with so much on screen

Don't forget that you have 4 times more pixel than the iPhone SE.

yea this might be the case but its got better battery life so you give and you get some

If possible, I will try to make a video on the shop's S7 and my s7's performance.
P.S. I wonder if G930X has Snapdragon because I can't find any info about this model in internet. If yes then everything's solved I guess

4th google result

Thanks man!
Then everything's solved in this situation, but another question comes up: why CPU in Exynos version isn't maxed in game Critical Ops? Because if SD version has 4 cores and it works better than in my phone it means that something has to do with cores.
Can it be the game's problem and i need to report this problem?
Sent from my SM-G930F using XDA-Developers mobile app

Possible the game need optimising for 8 cores, but I think the SD S7 has slightly better graphics scores than the Exynos too

Ok so I reported the problem to developers now I need yo wait for their response.

New update rolled out yesterday so I updated and C-ops works pretty smoothly(better!) but still lag spikes.
But now I downloaded Minecraft: Pocket Edition and IT'S NOT 60FPS! It's SOMEWHAT smooth BUT sometimes I see 20-30fps in scenes that aren't showing much of a landscape. And I tried playing HearthStone, NFS:No Limits, GTA:SA and Alto's Adventure (because it was lagging for some people but it works good for me) and I don't see 60FPS from them either. What the hell Samsung. FYI, I tried turning off App power saving in Settings>Battery>App power saving.
P.S. I have read some articles and people said S6 (8 core phone) has worse performance BUT in Marshmallow, not Lollipop so let's hope it will change in Nougat.

Exynos variant has a weaker GPU than Qualcomm so most games will have lower FPS. Exynos does have a stronger CPU and better battery life but that doesn't help out so much with gaming.

But what about iPhone SE then? It has garbage GPU (let's be honest) but CPU is very strong but still performs a little better than my phone. Maybe resolution helps.

I am thinking, should I sell my S7 for another phone? What do you guys think? Do you have any recommendations for another phone?
Sent from my SM-G930F using XDA-Developers mobile app

I wouldn't sell my S7 just because a single game won't reach 60 Fps, sure, the Adreno 530 on the SD Variant is a bit stronger but that doesn't mean the Mali T880 is weak by any means. I'm guessing it must be the software optimization probably because the developers were using an Adreno GPU or a Qualcomm developed gpu. Either way, try tinkering with the settings ( disabling Vsync and anti aliasing ) and see if that would work. You could also try overclocking the GPU if you want.
Goodluck
