[Q] Galaxy s4 CPU, music and more

B) another question: the octa core version supports 4G LTE doesnt it? or snapdragon has better 4G support?
Snapdragon 600 (1.9ghz speed, 4 cores) or Exynos 5 Octa(4 cores A15, clocked at 1.6ghz+ 4 cores 1.2GHZ A7)
1) what is faster? exynos or snapdragon?
2) which one is more effectively? (battery friendly)? (***in both high-huge use and low-idle use.. in which one battery life are better)
3) there are any benchmarks test for both of them.?
i just dont know which one is better..
Adreno 320 GPU vs PowerVR SGX 544MP3
4) which one is stronger?
5) i really dont know which version should i get.. US version(with 1.9ghz) or international(1.6ghz) their performance are really similar?
6) there is any stronger smartphone out now?
6) will the galaxy s4 have wireless charging?
MUSIC:
7) what about music? is there any quality speakers?
8) headphone will be HD/ very good quality.. ? (like in iPhone 5)?
8)

1) the snapdragon is over clocked so is supposed to be faster in cpu but the exynos won't lack behind.
2) for battery of course the exynos since only 4 cores will be running so if ur doing a low use the A7 will be running which are great for battery life and when you kick it to high use that's when the bug guns A15 come in play.
3)for the exynos no because it is not available yet but for the snapdragon it got the twice score of an iphone 5 so that gives a clear answer.
4)i think that would go to the powerVr since the exynos version is expected to be better in Gpu.
5)that depends on you.
6)of course it will but will be optional.
7) the speakers are supposed to be good than the previous models.
8) i am not sure about that but even if they aren't there are always beats.
hope i gave you a clear answer and if there is anything else you would like to know let me know.

thanks for taking your time for answering me
do you think exyons 5 will be overclock-able? i hope we will be able to get 1.8ghz or something without losing battery life or something..

yes i think after rooting and few kernel releases you will be able to overclock the Cpu and maybe also the Gpu but why would you need that the exynos on the galaxy s4 is already going to be a beast and it's expected to be in par with the snapdragon and also your welcome

Actually the Exynos is better in every aspect (battery speed and gpu) clock speeds don't mean anything a15s are faster than krait fullstop
S4 INFO

re
4 core?, I guess its Octo-core Exynos
Well unless you don't use both of them, you can't figure out which one is better.
May be someone may use and let us know.

well even if the exynos is better in every aspect the biggest advantage would still be low task using so its battery saving so everything else is probably the same or little difference and what do you mean clock speeds don't mean anything ?? have you seen the benchmark difference between the galaxy s4 and the htc one ?? and i know the A155 are better than krait that's why the snapdragon is overclocked
@samsingh02 it is octa core but like 4+4 so the 8 cores will never function together it would be like A7 for the low tasks and the A15 when you are on a heavy task like gaming
anyway the thing is the snapdragon is for 4G network and the exynos for the 3G network end of story.

CPU/Processor Showdown - HTC One vs Galaxy S4

Which processow will be better, Exynos 5 Octa or A simple Snapdragon 600 quad?
In my POV, Octa will be useless since it will be a battery hog and no apps really use that much cores and power. The S600 will be more efficient for day-to-day use since it consumes less power and will actually be used.

[Info] Exynos Octa and why you need to stop the drama about the 8 cores
AndreiLux said:
Misconception #1: Samsung didn't design this, ARM did. This is not some stupid marketing gimmick.
Misconception #2: You DON'T need to have all 8 cores online, actually, only maximum 4 cores will ever be online at the same time.
Misconception #3: If the workload is thread-light, just as we did hot-plugging on previous CPUs, big.LITTLE pairs will simply remain offline under such light loads. There is no wasted power with power-gating.
Misconception #4: As mentioned, each pair can switch independently of other pairs. It's not he whole cluster who switches between A15 and A7 cores. You can have only a single A15 online, together with two A7's, while the fourth pair is completely offline.
Misconception #5: The two clusters have their own frequency planes. This means A15 cores all run on one frequency while the A7 cores can be running on another. However, inside of the frequency planes, all cores run at the same frequency, meaning there is only one frequency for all cores of a type at a time.

Addition: I am not a Samsung fanboy by any means, however, the amount of incorrect information floating around about both of these flagships is starting to get annoying.
2nd addition: Read this as well, the big.LITTLE technology being used in the Octa is pretty amazing: big.LITTLE Processing

I hope that the overclocking or higher clock rate doesn't produce Moment-esque results.

In the US that is true, they are both S600's, with the S4 having a .2ghz higher clockspeed. Many of the other S4's will have the Octa Exynos chip.

Ah. I see. Different hardware for different regions. Like the One X.
Even though it's eight cores it is probably complete overkill. Yet another bigger number to put on marketing. How many apps will actually use that? How many apps use four cores at the moment?
There have been some articles about multiple cores being more for point of sale than for the end user. Even if you're signing up for a contract right now I doubt that much would be making use of it in two years time. So, the future proofing argument is moot.
It'll be interesting to see. Of course the galaxy builds of Android will use the cores. With things like the stay awake feature and pip it is useful. Outside of the OS I can't see it being necessary.

The "octa" core processor is complete bullsh*t. Imo, 2/4 cores are perfectly fine as long as they optimize it and perfect the hardware, why stack 8 cores when only 4 work at one time and no app will use all that power.
They should've focused on design to make it look less like a toy phone and use better finish, instead.
Oh the marketing..
Not HTC or whatever fanboy, just stating my opinion.

Very good read, thanks for taking the time to post it. Surprised no-one has mentioned that we need this in our Ones. Would certainly help with the battery.

Saying its a 8 core cpu is marketing simply put.
Like it has been said only 4 out of 8 cores will only ever be enabled at once max.
The GPU on the Octa might be better then the Adreno 320 but its have to wait for benchmarks.

"Octa" is not gimmicky or for marketing.
Octa is the name of the SoC, and how it was named is nothing wrong
There are 3 implementations can be used, and one with maximum 8 cores running at the same time.
GS4 doesn't use that impletations, but it does not mean the SoC cannot be "Octa". You have a house with 8 rooms but you know to open or you wanna open 4 rooms only, the house is still an 8-room house.

How do you know all 8 can run at the same time? Has Samsung demonstrated that already? Any links?
Also what would be the speed if all 8 are running at the same time?
Also did you see that an Intel dual core @2GHz beat the Exynos Octa in benchmarks!!! So all 8 cores running at slower speed might not be very good actually. It might even slow down things even more...
We recently demonstrated a dual core running at 3GHz at MWC in Barcelona. That chip was able to load games at crazy speeds. A game that took 15s to load on existing Exynos Quad core was loading in just 6s with our chip!

Its all about bragging rights really. Same as Samsung is doing with regards to Octa.
The the chip that could run at 3GHz could also very well run at 1GHz at just 0.6V (so consuming far lesser power than anything else in the market). A dual core at 1GHz is still good enough for all mundane tasks like playing videos or internet browsing etc. So in practice it would have been a very efficient solution. It was a real innovation really. Sadly the company did not have money to pour more funds into the program and has shut it.
It was demonstrated at Mobile World Congress in Barcelona in february this year.
Anyway point is, we did not need extra set of power efficient cores like Samsung is doing. We ran the same cores that could do crazy high speeds and even crazier power efficient mode! Thats a very neat solution.
Heres a press link: http://www.itproportal.com/2013/02/25/mwc-2013-exclusive-dual-core-st-ericsson-novathor-l8580-soc-crushes-competition-benchmarks/

A continuous running test monitored by an infra-red reader showed that the 3GHz prototype smartphone remained cooler as it uses less energy and in some scenarios, it could add up to five hours battery life in a normal usage scenario

Actually, no. At least not in my opinion. Octacore means 8 cpu cores on one cpu-chip.
I would see it like this:
You have 2 houses on your lawn which are beside each other. Every house has 4 rooms. You have to switch houses to open up the rooms. Just like the Exynos "Octa" has to, since it cannot run both CPU's at the same time.
If you are in a house with 8 rooms, you cannot simply be in all 8 rooms at once. You can connect the open doors between all the rooms, and since your in that house, you can freely walk in every room. But not with that implementation.
I wouldn't call the Exynos "Octa" an Octacore, its a dual CPU system with a 2x4 cores, with the difference that regular desktop dual CPU systems can use both CPU units at once, but not like the Exynos "Octa". Still, dual quad system comes closer than a pure octacore system.
This is kind of a hybrid. Nice technology for a mobile device, but at the same time, kind of unneeded / inefficient, compared to regular quadcore systems. Even the Tegra 3 system with 4 active cores and 1 companion core for standby tasks seems more efficient (in terms of "used space" and ressources).
Ah well let's see how the supposed and so called "octacore" will score in the future...

processor differences
okay I know both processor are snapdragon 600's but why is the galaxy S4's processor clocked at 1.9 ghz and the HTC One's processor is clocked at 1.7 ghz is it just an instance of samsung overclocking the s600 or are they different variations of the same processor, I have done some research and am able to find no clear answer to this question even on the snapdragon website????????

They should be identical. I think its just a manufacturer choice. But it could also be associated to termals or battery.
Cause Samsung took the higher frequency chips, there is the possibility that they also get the "better" chips: Lower Voltage for the same frequency. But thats just an assumption.

Just get straight to the point!

Right, I cannot make my mind up so I thought I would come on here, il make it short.
Which has better performance - Snapdragon 800 OR Exynos 5420
I don't give a flying f*** about 4G or 4K. Which one has better performance i.e which is faster?

I would say the Snapdragon 800 because more devs would get it= more roms, better clock speed, better battery life because of chipset enhancements, faster charging because of chipset enhancements. If none of those matter to you get the Exynos version.

To be technical, it seems that Exynos benchmarks are slightly higher. However, I believe that is without the HMP update. With that, scores will skyrocket.

I can't make my mind up whether to get snapdragon 800 version or exynos 5420. By performance i mean which can do more multitasking and which can run apps faster etc

From what I've seen the scores are indeed about the same on the benchmark front. They will both be good! I'm guessing the s800 will get more dev support and probably cm. It will all be your choice, do you want lte or not.

One thing that pushes me towards the exynos is that it has 1866 ram speed whereas snapdragon only has 800
Which do you think will be better in the long run?

^^^ forgot to mention that because exynos has higher ram speed then that means quicker performance.
So, which one should I get? Will there really be any difference between the performance of exynos 5420 and snapdragon 800?

You really do seem to have an attitude in your posts. Anyways, the phone isn't out yet so all anybody has is benchmarks to go by. Not a lot of real world use reviews out there to compare the two.
Sent from my Galaxy Nexus using Tapatalk 4

I guess the ram speed can be neglected in real life usage. The s4 with the s600 feels the same as the octa version to me. And that is while the octa s4 obliterated the s600 in Antutu and some other Benchmarks. Like I've said before, if you want lte and better rom support get the s800 one. If you're really spec whoring get a 8 core exynos.
Anyways, from what I've seen so far the s800 seems to be faster in Antutu but not that much so I guess they will be at the same level of performance.
I would get any device I could get which for me is the s800 since I'm from the Netherlands.

Easy. Snapdragon since there will be much more support for it from developers.

Also, don't forget, the 8-core is a lie
You have your normal 4-cores with an additional 4 'smaller' cores to handle always running less intense things. I really don't see the advantage to this, you don't get more out of benchmarks because those 4 'smaller' cores won't be used, except by some obscure background task that wouldn't slow down the benchmark anyways. It also won't help with the battery life, no matter how you spin it a clock cycle is a clock cycle.
The only time you will see gains from small memory speed increases are in things like calculating pie, so again, useless for day-to-day stuff. As other have stated, support. Qualcomm based will get AOSP based roms without any problems.
If you are looking to flaunt your meaningless bigger numbers around, by all means, get the 8-core.

It can't be a true 8-core. The extra 4 cores are far less powerful then the other 4.

Let me tell you some preludes:
The reason behind using 8 cores was to put in a pair of four aggressively powerful quad processors like the cortex A15 with another pair of less powerful yet more power efficient four quad processors like cortex A7.
This is the main intention behind putting all these 8 cores of ARM's big.little architecture. The purpose is to let the A15s handle power hungry tasks like web page opening, playing an asphalt 8 game etc while the a7s would handle "simple" tasks. This is more vividly demoed in this video:
http://www.youtube.com/watch?v=Zwbeb08W27U
Now, the way you are saying it is not a true 8 core processor as if you are
1. demanding 8 cortex A15 processors using 28 nm technology.
Do you know/have any idea what could happen if they all be available online at the same time in this case?
or
2. you knew there was a "true" octa core processor in the world, to be (or already) implemented in another device. IF SO, point us to that device and also explain what is the ideal to call a processor true 8 core.
It was never an intention of ARM to put eight A15s (for example) available for heterogeneous multi-processing.
Go here. Again 64 bit A57s are to be paired with 32 bit A52s.
Even the S4 equipped with exynos 5410 is an octa core processor device. It is just that the bloody CCI (cache coherence interconnector, CCI400) was crippled to enable all the 8 cores available online. Once the 8 cores packed in a SoC like this it is an octa core processor device. Whether or not you like it to call true 8 core.
Samsung/ARM worked on this and released another SoC (in the form of upgraded exynos) which has a working CCI that is free from the above mentioned flaw(s) which will have Cluster Migration by default and will receive the update that is made from Linaro team to enable all the 8 cores available online and therefore will become a "TRULY WORKING" 8 core processor which is implemented in Note 3.
These are facts, these have been heavily discussed in the general section of Samsung Galaxy S4 forums.
Oh, another thing- just because all these 8 cores are made to be available online it does not mean all the 8 cores will be working Simultaneously regardless of what application is in the process. Depending on the needs of the app(s) all these 8 cores (ranging from 1 core to the extreme case- 8 cores) can be used. If an app needs 4 cores, they can be used. If it needs 6 cores then they can be used. If it needs 8 cores then they can be used.
I personally am curious to see how it be going when all the 8 cores were used for an app.
And to the OP who's demadning a straight answer, my thoughts:
we do not know anything atm how power efficient and cool it'd be to have the HMP doing all these tasks. This requires
real life buyers buy the device
start playing with it
see how hot the device becomes (compared to another exynos device like s4).
It actually depends on those stuffs. You demand the answer as if we all knew from the beginning how exynos 5420 gonna perform in real life.

Replacing Exynos with Snapdragon 820 - is it possible?

Hi,
as the title says, is it possible to buy the exynos version of galaxy s7 edge, but then change the CPU later to a snapdragon 820?
If it is possible to change the CPU / GPU where would i be able to find it as a sparepart?
Thanks in advance.

Not possible. You'd be better off just buying a Snapdragon variant but I have no idea why you would want to do that when the general consensus is the exynos version is slightly better.

what he said^^

Surely this is not a serious question. You intend to desolder the existing cpu?

Not possible. You'd be better off just buying a Snapdragon variant but I have no idea why you would want to do that when the general consensus is the exynos version is slightly better.

Have you not been paying attention to benchmarks? The Snapdragon is way better than the exynos...

Although, I agree that you shouldn't even consider trying to swap processors. Maybe try to purchase a Snapdragon variant?

Having some experience with PCB and electronics production, no it would not be possible to outright swap the cpu.
But maybe if you are good at tinkering you could buy a motherboard off of a broken device and swap that?

I do not have a lot of experience with electronics modification so i guess my only option is to buy the Snapdragon variant from another country.
In this context does anyone know of any verified phone sellers on the asian market (where the snapdragon variant currently is available) that has a webshop with international delivery?
Also if i buy the phone from asia will i be able to use it with a telephone subscription in Europe or is there some fundamental differences on the phone depending on where you buy it?

Nope, the only thing sd820 is better than 8890 is GPU. In cpu 8890 kills the sd820 even on battery life.

Um, the 820 CPU beats the 8890 in single core performance. And battery life with the 820... well, I'll let my screenshots speak for themselves.

Numbers aren't everything. People with the Snapdragon are having issues playing videos that are 1080p and above. Video stops playing but sound still happens on youtube. Same issue the LG V10 had and another phone.

Nope it doesn't. Read Andrei on Reddit. Total score yes, on actual performance per cycle it doesn't. 7h sot over 48h total on my exynos.

But it does. The only thing it slightly loses in is Integer performance. But it makes up for this in floating point superiority. Don't forget, the exynos in single threaded stuff runs at 2.6ghz, thats about 18% faster than the snapdragons 2.15ghz. If we Normalized the clocks, theres really no question which ones superior in single core performance. As for OPs question, no, unless you are a total bada** it would almost certainly not work. You would likely need to replace the whole board, not just the CPU as it's all one big interconnected system. Especially on the sd820, due to it using the symphony system manager to dynamically offload tasks to the DSP and other blocks to save power and improve performance. On top of all that you would also have weird issues with the kernel being for exynos version for instance and have to get that fixed.
Tldr. Plz don't...

IMHO, The SD 820 beats the 8890 in some areas. However, To me it doesnt really matter which we have, The Device is extremely good with both. Runs a dream. However there is always the issue that development will become slightly frgamented...
We have TWRP for Exynos but not for SD devices. Plus im sure the ROM Will follow soon.
Whats interesting is that the S5 and Note 4 devices internationally came with SD 801 and 805 Respectively.
However after the S6 / Note 5 all Exynos product etc, Sammie decidied to flip that on its head :/ Personally I prefer SD chips. Solely because from previous experience they trashed Exynos and Kirin based ones. However Sammie really upped their game!

The reason Samsung didn't use the 810 last year was because it was an inferior SOC. It had a lot of heat issues. Up to that point qcom had been great. Also we have no twrp or kernels yet on SD because Samsung has only released exynos source so far for some reason -_-

consider samsung had a year with the 14nm processor, I would love to get my hand on an exynos processor. I have a feeling Samsung pay extra attention to their own processor than a snapdragon 820. Things like updates may come quicker too.

As Sammies Chip making process has grown (Yes Apple... Im looking at oyu) , its made Sammie a helluva ton'a muneh!
Seriously though, Samsung have done a good job with the last 2 gens of processors. S6 and Note 5 and the S7 8890 are nuts!
As for the sourcecode, well when its created by Samsung etc its not so bad
Back to the OP. No you cannot change the processor. Besides if it goes wrong, Warranty is instantly void

It does but there is a diffrence. When the exynos win it does it with almost 40% in single core which IS noticeable ..the sd820 only wins with up to 10% which is not ( talking about single core here). Hopefully anandtech will sink there teeth in to both socs soon and we will get a clear answer. As for boost clocks... the sd820 have a GPU boost which helps it in bursty situations but can't sustain it for long, that's the extra score in 3D for ya. But will see as time goes by..I have a feeling the exynos is the better overall

I still had almost 20% battery left in those screenshots.
Either way, I don't think you can say the Exynos is superior. It's better at some things, sure, but the 820 also beats the Exynos in several areas. I have used both extensively and in real world usage, you can't tell a difference. Only benchmarks show the difference.

The best win the exynos pulls off in single core is in AES with a 57% win over the SD 820. In the same category the 820 wins sha2 with about a 40% win. And the exynos is clocked almost 20% higher... The exynos 7420 Mali GPU also had a burst clock. It ran at 650mhz unless all cores weren't loaded it would boost up to 720mhz for bursty workloads. In floating point the snapdragon pretty much wins everything despite being at a significant clock disadvantage. If we under clocked the exynos to 2.1ghz it wouldn't even be close IMO. In fact the Integer wins may be largely lost when clocks are normalized.

Qwhy don't people to a trans Atlantic phone exchange. I'm sticking with the exception exynos for the battery. Still waiting for a decent screen protector and battery case though.

S7 edge Vs Note 5 CPU

I traded my note 5 for the S7 edge. I did a side by side comparison after the fact, just opening up some apps and the note 5 was significantly faster. Now i know the note5 is a octa while the s7 is a quad. But I remember Samsung boasting about how its the fastest on the market. I then did a side by side with my buddies s6 and they were the same speed. Has anyone else experienced this? Im wondering if i got a bum phone as im currently in another thread talking about the phones cpu temp. thanks

The quadcore snapdragon should be about 20% to 30% faster than their latest exynos octacore. Also, ram optimization will be diff on both phones. In real world test, the edge 7 runs faster and has better battery life. Once the apps were loaded into the ram on the s7 it blew the note 5 away. I also tested both devices. Your device is normal, the real world performance is slightly better. Not night and day

Samsung optimises there own socs better than the SD variants, see speed tests on YouTube on s7 VS apple 6s..every time the exynos won over the 6s but the SD looses every time (in opening apps etc)
That's the big drawback with having other than home grew socs in your phone, they are not as optimised as the original one.

Very much depends. Single core? Yes. Multi core? No, the other way around. The general consensus is that, as a CPU, the Exynos is the better hardware. But the GPU on the Qualcomm SOC is faster and better.

Well yeah in multi core test you wont be winning any benchmarks but more cores dont always mean its faster and or better. Look at what apple does with single and dual core processors. Most of all the bench mark test on both the US version and intl version are pretty neck and neck both versions winning and losing some test to each other. On paper, the 820 should offer a performance boost.

There are plenty of benchmarks on this. Exynos 8890 wins on multi-core tests and also real-world tests. It looses by a small margin on single-core. RAM speed is really no-contest, Exynos drives the RAM 50% faster.
