I need your suggestions. Can any one please make me understand the which is the best processor from Exynos 4212 Quad, NVDIA tegra 3, Snapdragon 4 dual and why?
Please tell me. That will be very helpful to me
From benchmarks, the Exynos CPU was quite a bit better than the other two, and the Mali GPU in the S3 also out-performed the others as far as I can remember. Search for some benchmarks comparing them to find out for yourself.
It should go this way:
Processing power: Exynos 4412 Quad > Qualcom S4 Krait > Nvidia Tegra 3 Quad
GPU power: Mali400 GPU > Adreno 225 >= ULP GeForce
But i read somewhere that S4 Krait CPU which is based on ARM Cortex A15 chips could offer more power without consuming as much energy than the two Quad core beasts.
My first thought when I heard about Nvidias 4+1 CPU was, how can it decide when to switch from single to quad core?? This sounds to me like a prototype for a constantly lagging device.
But I'm not as deep in this matter as to make a qualified statement.
It is just a feeling, since neither Intel ,AMD, Qualcomm or Samsung build their CPUs like this.

Coming off a Tegra 2 device and patiently waiting this Verizon version of this phone all I can say is Tegra is terrible. At least on my phone it was, heating up on simple tasks like browsing homescreen.

It actually works very well, the standby time on this phone is the best I've ever seen. It's needed though, because this chip is thirsty. Whether that's down to poor drivers or the design I don't know. Maybe a bit of both. Anyway I like Tegra 3, it IS very fast and you have those Tegra 3 games. Just look at Dark Meadow, the graphics are amazing and it runs smooth as hell.

I can't imagine how this ever will work without occasional lags.
How does the task scheduler on a tegra 3 predict when to activate the 4 cores ?
Starting an app and wait whether it will need more power will lead to a lag, when it maxes out the single core.
It's not 4+1 but rather 1+4.

I have no idea how it works, as the fifth core is handled directly by the soc and not the system. Maybe someone more knowledgeable than me can shed some light on this. I haven't encountered any noticeable lags compared to my SII though.

Hey guys, bit of a noob question here but nevertheless i shall ask it anyway
So as we know the samsung galaxy s3 has a quad core processor which churns out 1.4ghz which is rather fast!
But ive only seen the overclocking abilities for it to run at 1.7ghz max? Why is this? the galaxy note can run at 1.9ghz via dual core.
my question is this, why cant is run at over 2ghz? i mean 1.4 is enough but id like to say "my phone can run the same speed as my laptop"
Sorry for the noob-ish question but if anyone would reply, it would be great
Jack.
I've yet see a phone that can open the http://www.theverge.com/ at a decent speed.
I overcloceked to 1.6Mhz and still didn't make any difference.
Why would you want to run at 2.0Mhz?
Running at that speed would juts increase battery usage and overheat the CPU.
Ah right, yeah it even took my computer like 10seconds to load that site!
why wouldnt you want a phone to run at over 2ghz? admittedly your right about the overheat and battery life
For that exact reason...heat and battery life. What more reason would you need. For most instances its unnecessary. Isn't saying its quad core enough...

The same applies to pc chips, more cores mean more heat. It's why many current dual and quad core chips are faster than the newer hex and 8 core chips. Less cores means more room for heat tolerances.

The reason dual and quad cores are faster is because of the limitation of software and how multithreaded it can be (and there will be a point of diminishing returns which will be a lot sooner for basic programs).
I have a dual core 3ghz pc and my new pc is just 2.8ghz quad i7.... My old pc must be much faster!

I lol'd. 1.7ghz quad is leaps and bounds better than 1.9ghz dual. 1.7 and 1.9 ghz isn't that big of a leap, but 2 cores versus 4 cores is pretty significant. Jelly Bean improves multi-core processors so the SGS3 International version is going to be even more sick-nasty (in a good way) once that rolls out.

I dont know why u compairing a desktop pc to galaxy s3. A pc will win hands down but I have a fairly upto date pc. And since got this phone i never really use it unless doing video editing. This phone is great and is as good as a standarded laptop If not better. This speed is brilliant to, maybe jelly bean will make a great phone greater. And another thing apps for this phone weather it be media or web browsing etc isn't really pushing this phone to the limit. So give it a while might see a bigger improvement.

There is more to CPU performance than the clock frequency, core efficiency is the key here.
E.g. Intel P4 processor -v- Intel 'Conroe' Processors.
The newer Conroe processors were smashing the granny out of the older P4 processor despite the significant lower clock speed. Does that mean the newer processors are inferior? No, it just means each clock cycle handles more instructions.
If you want willy waving rights about how awesome your phone is go buy an iPhone and check if theres an app for that.

Android 4.1 Jelly Bean
In "Project Butter," Google has worked to improve graphical performance and touch responsiveness. On the graphics side, Android is now v-synced at 60 frames a second, with triple-buffered graphics. The result is that scrolling, paging, and animations are all smoother and consistent.
To make touch feel better, Google is making it anticipatory, so that the touch data applications receive corresponds to where fingers will be the next time the screen is redrawn. This means that apps won't have to be one step behind where the user's fingers actually are. Jelly Bean will also immediately ramp CPUs to their full speed whenever touch interaction is detected. This avoids lag caused by slower processing when the CPUs are in low power modes.
For developers, the Jelly Bean SDK will include a new profiling tool, systrace, that provides a clear visualization of their applications' use of the CPU, GPU, and other system components, so that bottlenecks can be more readily identified and resolved.

Nothing specifically says "Jelly Bean is optimized for multi-core processors". That said, that entire article shows that Jelly Bean was brought about with processors in mind. You really think Google is going to make an OS that will "ramp CPUs to their full speed whenever touch interaction is detected," and "include a new profiling tool" that shows applications "use of the CPU" but not make sure it's going to be optimized for dual and quad-core devices? Also, keep this in mind:
Jelly Bean Lite
Jelly Bean Lite: Android OS definitely works efficiently on high-end dual-core phones. However, when it comes to lower end devices, the performance, reportedly, becomes very poor. Many users have also urged Google to release a lighter version of Android OS for midrange and lower end smartphones to rid themselves of the problem of performance of OS.
Rumors are already rife that Google will release a lighter version (Jelly Bean Lite) for smartphones with limited CPU and storage.

I'd say you're probably wrong about Jelly Bean not being optimized for multi-core devices.
What really matters to the average person is that in real life use the S3 really isn't that much faster than S2, so until we get an OS optimised for those extra cores all we really gonna have is the "My processor's bigger than your processor" bragging rights.

Benchmark scores do show that it's a decent difference in the S2 versus the S3, though overall I would have to agree with you. But Jelly Bean will definitely be closer to the mark than Ice Cream Sandwich in terms of CPU optimization. That's my personal opinion based on my above comment of course.

First off: note that there are lots of different versions with the same "S3" name, most of which probably are not and never will be compatible to your current carrier's network.
The i9300 uses hotplug technology to completely shut down cores when their processing power is not needed and re-awake them whenever you open a CPU-intensive application. So in the bottom line it does not drain more battery unless you actually need more power than the other one can deliver.

It doesn't have to be CPU intensive application, it can be a normal application that will use all cores, each at not maximum frequency.

The only thing I like about the dual core versions is that they come with 2GB of ram, which should be standard for a Top End phone, specially with the amount of software that Samsung puts on their phones.
Of course, I know the dual cores are Cortex 15 which is a newer core but I don't value that as much as I do the 2GB ram.
Other than that, I'm really happy with my SGS 3 (international version, unlocked)
You can always downgrade with custom kernels whenever you want

Not necessarily. Everyone is using their phone differently. Every battery produced in factory is also not 100% identical. So basically no point trying to compare between dual or quad.

No, I'm saying that what I like most about the dual cores is the 2GB of ram they come with. I'm comfortable with the battery life of my quad so I don't complain about it, and don't even wonder about what the duals can do.
I had a SGS 2 (still do) and even with the pumped processor (and slightly bigger battery) this one still lasts more that a day of relatively heavy use so battery life is not a problem. Maybe the new duals cortex A15 have better battery life than this quads, maybe not so much BUT, they're not quads :laugh: and that was a good selling point (for me).
If Samsung had put the same 2GB of ram on the quads (like they did for the Korean version -envy-) then no one would want a dual, and no one would complain about battery life -or even wonder about it-, but they didn't.
If you ask me, the best phone to come will have 2GB ram (LG has announced already and Xiaomi too with the Mi2 coming October), then our quad SGS 3 will come short, that's my only complaint.

Also to the point where the dual core has lte which destroys your battery.
The dualcore one uses a qualcoomm krait cpu which is based upon cortex a15 unlike the quad exynos which is based upon the cortex a9 cores. The a15 architecture is by design depending on the task to do up to more than 100% faster as compared to the a9 in single core and single threaded tasks. So speed wise they are quite equal, while the exynos has a better gpu, the krait is made in 28nm, while the exynos is made in 32nm, so to make the story short: in theory the dualcore should be as fast as the quad, while using less power, assuming both have the same battery, the dual should last longer in theory, but i havent seen any thorough comparison tests of it until now.

In theory is the most important thing here. And, for every app that can use all 4 cores the quad will have the upper hand. I've seen the reviews and the SGS III still manages to beat the duals (A15) in general performance tests.
That's why the new top dogs will use 4 Cortex A15, and 2GB ram configurations, those will be unbeatable.
Still, LTE on the duals will kill all battery life differences.

I disagree. 2 cores process a task longer--longer time=longer battery usage. Shorter time for 4 cores--4 cores=high battery usage. Am i making sense?

Wrong.
The krait is not pure a-15.
The exynos is not pure a-9.
If anything the both meet somewhere in the middle, the exynos is built on a smaller die than standard a-9's and a 128bit instruction set (a-15) and is fabricated using HKMG process (reduces power leakage by up to 50% if my memory serves me right)
The krait is still using the older, less efficient Lsion process and is nowhere near as good as HKMG.
Samsung have tweaked the sh*t out of the exynos 4412 and it has been around for a while, the krait is new tech, not nearly as much time to optimise it.
Now another point is that development on the US version is nowhere near the level of development for the international and has a lesser GPU and DAC.
I wouldn't trade for anything.
Well in saying that I'd like 2gb of ram, but with this SOC.

The S4 is halfway between the Cortex A9 cores and the new Cortex A15 core that we have. So it is decent enough of a CPU. I am not sure how good of a GPU that is. None of my devices the past couple years have had Adreno GPU's At least it wont have to work as hard with the lower resolution

From everything I've seen and experienced the exynos 5 is the better of the two. The a15 is a more powerful core than the krait core, that with the higher clock speeds and the better GPU makes for a better chip. Personally I have never had my n10 lag at all. Maybe you just got a dud?

But the Exynos 5 has to run that massive screen res. Also, the reason I think that Qualcomm modified the core was because of the power consumption. Stock A-15 core consumes quite a lot of power.

The Snapdragon S4 does not use an A15 core or any derivative of an A15. Qualcomm has ALWAYS completely designed their cores custom and has almost nothing to do with the current major core from ARM's reference design. Additionally, the S4 was designed and released before the A15 MP-Core was even finished with its design phase.
The Krait core uses a similar (but not the same) triple wide decode stage like the A15 core, but it uses a completely different 11 stage execution pipeline compared to the A15's 15 stage pipeline. The higher stages of the pipeline allow the A15 design to break things down smaller and achieve higher frequency, but if there were to be a failure in computing then the A15 must wait a longer time before it can start over where the Krait core doesnt have to wait as long, but also isnt as efficient in " normal" circumstances. Honestly the integer performance between the two cores is pretty close, but I think I remember seeing that the A15 has a lot stronger floating point performance. So I guess it really depends on your workload.
FYI, the Exynos 5, Tegra 4, and TI OMAP 5 processors are all based on the A15 core design. Qualcomm is the only major player who does not base their processors on the ARM design

Do you mean a drop in framerate during the animation when closing Maps? I notice a minor framerate drop which lasts as long as the animation does, but if that is it, I'm kinda wondering why you bought an android device in first place... I have not noticed this before and I cannot imagine anyone would using the device for its intended purposes. If you take any android device, you will find a fps drop at some point... Maybe return it and take an iPad? iPads do not have the issue, on the other hand there's a lot that iPads do not have ^^

THANK YOU!! my god I've had to explain this so many times! Qualcomm licenses ONLY the armv7 instructions and not arms designs. They design their own chips from the ground up and GPU, so please people stop saying Qualcomm is a cortex series processor because it isn't. Samsung and the rest license arms design and modify it, in Samsungs case they tend to increase the IPC slightly and give it more memory bandwidth.
Also to answer the question, exynos 5 will do better at higher resolutions and they will be very close in lower resolutions. S4 will be better in multi thread workloads more then likely and exynos will have better float performance. Exynos is better for games once the thermal throttling is fixed.

They design their own chips from the ground up and GPU, so please people stop saying Qualcomm is a cortex series processor because it isn't. Samsung and the rest license arms design and modify it, in Samsungs case they tend to increase the IPC slightly and give it more memory bandwidth.
Also to answer the question, exynos 5 will do better at higher resolutions and they will be very close in lower resolutions. S4 will be better in multi thread workloads more then likely and exynos will have better float performance. Exynos is better for games once the thermal throttling is fixed.

The 50 percent extra memory bandwith doesn't matter so much considered that the Exynos has to move almost twice the amount of pixels.

Memory bandwidth makes a pretty big difference when it comes too resolutions. I.E 8600gt ddr2 vs ddr3. Wider memory bus and faster memory makes a big difference in higher res performance of any GPU
Also will help with GPU compute performance for future apps utilizing the Mali t604s compute abilities

But lets say that Exynos uses the whole 12.8 gb/s bandwith. That means that to move twice as less pixels you would need 6.4 gb/s so memory bandwidth isn't an issue.

But that bandwidth is shared, unlike on dedicated GPU where it isn't. The total system bandwidth (not including buses for modem or w.e others are there) on the exynos chip being higher is gonna give it the edge in any situation considering the closeness in performance between the two. It also can't be denied that the Mali t604 has a edge in horse power over adreno 320 because even at the n10s resolution it comes within a couple fps of adreno at 1080p resolution. Not saying it's a big difference, but the exynos is the more powerful all around chip and that's just in is dual core form.
Edit: Also its a known fact that Adreno has crap fill rate compared too Mali or Power VR, Adrenos Strength is Geometry performace so it takes more of a hit the higher the resolution than Either the Mali t604 or the SGX 554MP4 which both have higher Fillrate and the SoC we have to compare both have higher bandwidth to facilitate that so we dont get bottle necked.

Finally a lot of exerts here about GPU
, I know it is not related to topic but me and my girlfriend have Galaxy Note 2 and S3. As you all know they are the last ones to use the elder Mali-400 GPU. I love playing games and I am getting my girlfriend used to them too. So I was wondering how is our Mali400 GPU holding up against the new coming 1080p Adreno 320 devices? It is clear the future is 1080p. I am either planning to switch our devices with a couple of Nexus 4s or Xperia Zs. Because I fear our devices are about to be outdated with the next game right around the corner. So far they are doing just fine with Modern Combat 4 and the all other graphic intensive games by playing over 28-30 FPS. But according to the GLBenchmark 2.5Egypt they are useless against new Adreno 320. However I have read that most of the games were designed for high fill rate power and Mali 400 is able to beat Adreno 320. But on the triangle tests, it just bottlenecks.
So what is your opinion about it? I will our devices do another year and half for the new games? Or should I make the trade? Or should I just buy a Nexus 10 with 2 users assigned and continue games on it? I
Thank you for reading.

They will hold on, my SGS2 runs all of the current games at the highest settings ( I haven't tried GTA though) without any issues, the Adreno 320 is far better than the Mali 400 MP4 though
Ya, Im pretty sure they will still play games a year from now. Until the market is completely saturated with devices like the Nexus 10 in power we wont really see large jumps in system requirements. That will probably only happen a year or two from now once all the new phones and tablets are made with A15 processors (or Qualcomm equivalent) and beefy GPUs.

The S2(Mali400) plays GTA3 without a hiccup.
The exynos dual is very power hungry compared to the s4pro but it is also the most powerful arm processor out today. Nothing else yet released (I said RELEASED) is as powerful or can match its bandwidth. Having said that I'm sure a normal resolution 1080p screen in this form factor with the s4pro would be a nice fast tablet. Right now the exynos dual is pretty much the only thing outside apple that can push the resolution that the n10 has. I think if they had put another gig of ddr3 in this thing there wouldn't be so much stuttering in certain instances. Besides the thermal cutoff the n10 is starved for memory as it has to share normal duties and its ram with the graphical load of pushing all the pixels of this monster resolution. You are lucky to have 300mb of ram available at idle on the n10 vs over a gig available with the s4pro on the 720p screen of the nexus 4

First off you must be rooted, and before you go complaining about lag, battery life, poor gaming performance, etc, have a look on the internet because chances are you either have a faulty device or someone has already created a fix. Many new phone manufacturers will market their device as quad or even octa core, tricking the market into believing that smooth gaming and UI are a result of having a 1.7ghz quad core or such when in reality the chip pushing the pixels is the GPU, probably the most important factor in a chipset which gets likewise upgraded every generation but is not advertised as heavily as the CPU.
So why the lag?
The Tegra 3 CPU is linked to the GPU, therefore, the GPU will only scale up to its maximum frequency if the CPU has activated multiple cores and is running at a high clock speed, however to save battery life the Tegra 3 prefers to use 1 core. This is why most Gameloft games lag (as they only use 1 core). Fortunately there is a fix, you can allow the GPU to scale dynamically by using the attached init.d script, if it doesn`t work, try using smanager, setting it to run on boot with su access. This will allow the phone to weight its processing more on the gpu, allowing the power hungry 40nm CPU to scale down to a lower clock, hence saving power. If you get stuttering in the UI make sure you flash a custom rom and enable the GPU 2d rendering or GPU UI rendering option in aroma.
Why won`t my phone scale to 1.7ghz all the time?/Why does my phone only use a single core when clearly more power is needed?
The Tegra 3 is also not a 1.7ghz quad core per say, the processor can only scale to 1.7ghz when using a single core. This is buggy as sometimes the processor will get stuck in single core and cause lag and unnecessary battery drain if the frequency scales too high in order to multitask. To fix this, head over to Nik3r`s thread and flash his elite kernel, hxore is also great however it does not include blades commits (however the removal of hotplug will give similar effects). These blade kernel implementations will allow the phone to use all four cores at 1.7ghz, dramatically assisting multithreaded applications and games that are cpu intensive but poorly optimized. To enable this use attached script.
My Launcher is constantly reloading/Heavy open world games lag/Sense multitasking sucks!
Elite also features swap memory, although I cannot recommend it for daily use, if you are a heavy gamer, it will help in any unity or unreal engine game and also stops the launcher from reloading which can be annoying (sense is a ram hog). These come in various sizes which from 128mb to 256mb and performance gains really depend on usage or what you think is necessary.
Performance is great but battery life is terrible
You might also want to try UV your phone,again poses some risk but cannot cause permanent damage like the aforementioned swap memory, before doing so check you tegra 3 chip variant. These range from 1-4 with the original One X being 1-3 and the One X+ being mainly 4, 3 if you are unlucky, the higher the better and faster/cooler. You can check by using a terminal emulator and typing:
cat /sys/kernel/debug/t3_variant
I personally own a variant 4 which operates well even with a 100 millivolt UV, however as all devices are different you will have to experiment with this. This option will keep heat down and save power as the tegra 3 has plenty of CPU to spare. I will also provide multiple UV Scripts for you to try out (stock elite is -25 millivolts). I also recommend using the phone in powersave when not gaming, the majority of games will probably run well even in powersave (limited to 1.15ghz and 3 cores).
Display uses the most power/auto-brightness scales too high or low/I just want to turn my button backlights off
You can also use a brilliant app called Lumos to manage screen brightness (the bright SLCD 2 screen does have its drawbacks) and backlight brightness or you can copy the lowest brightness apk from insertcoin v 3.2.1.
Developers aren`t releasing updates
Developers work for free and are devoting there free time that they could be spending on leisure, family or work to better our devices. They are not obliged to do this and release their work publicly. Most developers will listen to requests but please do not pester them excessively just because they see it unfit for implementation. please thank all developers for there hard work and even consider donating. A simple thanks is always appreciated, happy flashing.:good:
Update 1: New scripts!, seemed to have fixed a problem regarding the gpu failing to decouple, could explain why people were seeing no improvement. Custom folder if you want to tailor your device`s performance to your specific needs/rom/kernel, standard, just contains scripts that should provide a sizable performance gain for all devices.
How do I use this script? Flash it?
Thanks for the explanation!

Decide by yourself which scripts fit your needs. You will most likely want to use decoupled gpu and try different io schedulers. For 1.7ghz quad and uv I'm not sure if they will work on att . Which kernel do you use?
Whatdo you want to achieve?

THX for that. I tried two scripts with ChaOS and it feels snappier

You`ll want to look into a custom kernel as all use the smartmax governor which has better batterylife than ondemand and use cpuquiet driver which switches cores easier, ie uses less power, generates less heat as cores are clocked lower but more are active. Try the undervolt script but use a less aggressive one if you experience crashing or lag.

Sent from my One X+ using xda premium
UV is undervolting. In this case each frequency step is undervolted by 50/75/100 MV which will help to keep your device cooler and thus saves batery and prevents thermal throtteling but also might cause instability. For the i/o sheudlers ask google, its to complex for one small post. But in a nutshell it determines in what order tasks are handled.
