[Q] Does the Lack of 64 BIT IN THE Snapdragon version really mean much? - Galaxy Note 4 Q&A, Help & Troubleshooting

Does the lack of 64bit make much of a difference for between now and 2016 spring where I'll most probably get my next phone after this note? Will it take some time for 64bit to really be widespread in terms of apps and games and software etc which would make it ok to get this note provided I upgrade again in 2016?

According to anandtech, the Exynos version might have a 64bit capable architecture (Cortex A57), but the chip's drivers and firmware run in a CAL mode (32-bit compatibility mode). This means that while it benefits from some of the performance and power saving features of A57, it won't be running 64bit code.

Same as Snapdragon 410 devices launched. No 64bit code because Android 4.4.4 can't run 64bit but Android L will.

The anandtech article: http://www.anandtech.com/show/8537/samsungs-exynos-5433-is-an-a57a53-arm-soc
It seems to imply that this was never meant to be a 64bit SoC, and may not ever run in 64bit mode (at least without some hacking), even with Android L.

They share their opinion. I checked HTC Desire 510 have snapdragon 410 too. In source code doesn't have AArch64 implement too. But it doesn't mean an update with android L won't bring implement AArch64.
Anandtech think Exynos 5433 is 32 bit and they are total wrong. Now they can wrong too.
Exynos 5433 with AArch64 at first is line up Exynos 6 but they don't want Snapdragon chipset can't sell-out when people want Exynos chipset. The very same story with Snapdragon and Exynos in Galaxy S4/S5 and Note 4.

I think some people answered your question but not fully lol. Simply put this whole argument over 64-bit and 32-bit is kind of pointless. As others have stated the exynos version isn't even running in 64 bit mode. Android L has yet to be released and there is no way of telling if it can be put into 64 bit mode. Even if it could, if you decide to get a snapdragon note now, you will be good. Most apps will not be 64 bit compatible out of the gate, and will take some time for them to be so. You will not experience any major loss in performance, and maybe someslight difference in battery life. Hell my nexus 5 on Android L developer preview which isn't even finalized runs AMAZING in comparison to kit kat, and in no way shape or form is the nexus 5 64 bit compatible. Don't let 64-bit fanboys sway your decision on an exynos vs snapdragon note 4. They both will be powerhouses with android L. By 2016 for your next upgrade there will be plenty of 64 bit phones, especially the S6 at that time, and the Note 5 in the fall.

It will be years until 64bit is widely accepted and used so you'll be okay. I'm basing this off of the windows transition which is still occurring after all these years.

People get new phone every 18 months on average, I would imagine people hold on to computers for much longer, so analogy to windows regarding transition is probably wrong. Another example for disparity would be OS updates, Google has 2-3 updates of Android a year, where MS would be every 2-3 years?
Also the newest ARM architecture is probably 20-40% faster (per clock) and Google has a chance to write more efficient OS (like replacing JIT with ART for example). So I'm willing to predict that transition to 64 bit will be much faster for the phones than it is with computers. Of course all this depends on translating theoretical gains into real life advantages , if they don't show up due to poor execution, then all bets are off.

Possible Port for Windows 8 ARM for mobile

Hello,
I've owed an x10 and SGS-II.
Windows 8 ARM hasn't been released as of now but is someone planning to port it to SGS-II?
The reason I ask is because it looks very nice & would love to see something different on SGS-II
This is just a discussion any constructive comments are welcome.
as a pure development project it might be fun to do such
but as a daily driver OS, Win8 is definitely a no go
maybe will see win8 in our sgs III with 2ghz quad core

i agree
as Win8 is basically = Win7 + Windows Mobile 7 Launcher + ARM CPU support
so that is basicaly a super beefup version of Win7, which translates into very heavy hardware requirement for it to run properly
basically you need a laptop the size of a phone, for it to run
Haven't people been able to "run" it with ancient Pentiums and 128 MB ram?

I don't think so mate. The requirements for Windows 8 ARM is pretty low. Microsoft announced that it will run very smooth on tablets (they did a demo as well) and it requires pretty low resources (since windows 8 itself uses a Very low ram).
People at xperia x10 are looking forward to port it so I thought why not?
SGS-III? lol. I'd dream about it.

Don't make the mistake of comparing mobile to desktop. MHZ/GHZ processor speeds don't mean jack when comparing between CPU/GPU architecture types.
Just because some spec somewhere says it's designed to be able to run on ARM processors and some or our phones use ARM processors, doesn't mean we are go for launch. We may not be comparing apples with oranges here, but we certainly are comparing tangerines with oranges. Some of these chips can be much bigger and power-hungrier than anything we see in the SGS2
kal-el can totally Handel it perfectly.

I guess they will eventually merge WP7 and W8 for ARM, same thing that is about to happen to Android.
For now I am quite happy with Android on my phone, and if the Win32 pogramms wont work on a W8 tablet I see no point in getting one either. Android is growing like crazy (software and hardware), so I can not see a reason to abandon this platform (except maybe for MeeGo, incredible what the people did with the n900).
Although Tablet+VLC would make a hell of a mediaplayer....
Win phone 8 on SGSII
Reviving this thread...considering now much is known about the platform, is there a chance of a port on SGSII?
i think we will see some tryout ports coming very soon.
ive run w8 on some really crappy machines, much more worse specs then s2.
however i think port is depending on the fact how many people will really want it and how many devs
are willing to do it..
whats the OS in nokia lumia 920 windows 8 or windows 7?
This probably isn't possible because I think windows phones are partitioned differently. Basically its gonna be difficult or nearly impossible.

You guys do realize that the GSII is more than capable of running WP8? The Lumia 920 has a S4 dual core and handles it effortlessly, the GSII would be able to handle it aswell since the Exynos 4210 is still very damn good.

It's not the matter of hardware. There are many other things to consider too. Already we have problems with CM10. WP8 just spells more trouble.

[Q] Would u like Quad or Dual in your next note?

Since the launch of SGS3 is around the corner and the next note will probably come within next few months, I thought of starting this thread to know how many users prefer having Quad Exynos 4 ( similar to SGS3 which is based on A9 arcitecture with Mali 400 GPU built using 32nm manufacturing process) or dual Exynos 5 (A15 architecture with Mali T604 GPU which is based on probably 28nm manufacturing process)in our next Note...
Cast your votes in the poll
You should put a POLL, it would get more people interested. But for me, I'd rather get the A15 with the Mali 604T since A15 is supposedly to be 40% faster than A9 and the Mali 604T will blow the Mali 400 away.
Definitely the dual A15 with Mali 604. No doubt.

Quad! I don't care if I don't use it, and I don't care if I don't need it.
It just feels good to have that much power in the palm of your hand.
I'll benefit from that much power since I play games and I look forward to more capable emulators in the future.
I don't give a CRAP about the amount of cores!
I want the most speed that's possible, if that would be with dthe dual i take that, if it's with de quad, then thats my way to go...
Can't vote in the poll because i want speed, and since it's not sure wich one is faster i can't vote!
PS
I think the Exynos 5 will be released @ the end of this year, and the Exynos 4 tomorow
If that's correct i go with the Exynos 4, i hate waiting
what the note lacks is a decent GPU. the current GPU can't efficiently handle the 1280x800 pixels. however what i want more than anything is 1. non-pentile screen that is FLAWLESS and 2. a bigger battery still ~3000 mAh like the RAZR max. I would gladly sacrifice a few mm for a larger battery. I find it stupid how HTC decided to go with a slim and NON-REMOVABLE battery and storage to save a few mm. Seriously? This is why HTC is falling in a deep pit.
Exynos 5 dual, it has more power and is more efficient

EASILY the A15 with the T-604! Come to papa!
The fastest clock speed and the best GPU is all that matters. 2.2 ghz 2 core with a fab GPU will blow away a 10 core 1.0 ghz with a bad gpu everyday every way.
How about the beast Quad Core A15 Exynos 5450 with Mali T-658? Ok, ok, I know technically it hasn't been built yet and will probably be for tablets, but wouldn't mind seeing it in the Note since it is a tab/phone hybrid.
But as for the current SoC's available now, I would take the A15 dual Exynos 5250 with Mali T-604.
More likely, I think Samsung's road map would be to release the flagship Galaxy S lines (in this case the GS 3) with the latest SoC's, then the next Note (Note 2 in this case) would get a slight spec bump based on the Galaxy S 3 with a faster clocked CPU/GPU combo of the Galaxy S 3 line 6 months later, then the GS4 would get next Gen SoCs with the Note 3 getting a spec bump of the GS 4 SoCs, etc.....
I am sorry.. but this amounts to techie circle jerking..
Quad core processors came out for the PC when not a single application could even use two cores, much less four.. Even today, several years later, for the very very vast majority of applications, it is hard to get a PC to run more that one and a bit processors.. My i7 snoozes, and even cranking up real time low latency audio(a stressful activity)it runs 2 processors at 30% and one at 5%
Therefore I frankly do not care if they put a hamster and a wheel inside the device...as long as the results in operation of the device meets my needs.
So, given my customer needs are for smoother, faster and more reliable operation with better battery life and an enhanced user experience, Samsung can put whatever they want into the device...
In saying that, decisions by the majority of folks are driven by what they think the specifications mean, rather than the impact or result of those specifications in real life usage, so while i am sure its not necessary, a next Note will for sure have a quad core.
With a single core my galaxy s with ics is snappier than my note. Finally its the software I guess.

I agree. Android multitasking would need to be vastly different than what it is today, and on top of this the RAM specs need a major bump to even begin to show advantages in multi-core processing.
Also like you said, it has not mattered for deskptops and laptops what the real-world benefits are, just what the consumer feels about the value in their purchase. Nowadays it seems people are more concerned with the number of cores as opposed to the clock speed.
I do like the approach that Ti has taken with the OMAP in dedicating low-power cores to low-power functions, and feel that it really has potential in mobile devices, but they seem to be a step behind when it comes to the bigger tasks of mobile processing. Intel being on the cusp of Haswell has me excited to see what they can do in this territory.
Dual Exynos 5 for me at the moment.
It'll be interesting to see how they market this dual core a15 processor because joe public, will always think more cores is better. I do feel though that the note 2 might not have the same internals as the s3, like our notes had the same as the s2. For the note they seemed to put in all the best tech they had on offer at the tine, so if the a15 is ready to go by November time then I think they'll defo use it unless something better is available.
Dual core with speed.
Quad cores mean squat if they slow the primary usage down.
I'd rather get a dual than a quad even if its on the same generation and process so long as it is clocked higher. Give me a smaller process, newer gen chip and better gpu? There is no choice.
Id go for the i7 3960x and gtx 690 if they can squeeze that in the next note but I think I wont get a choice and will just end up with whatever Samsung puts into the note 2.

I agree with you....the main reason I created this thread, because I wanted to know how many members actually know the effect of system architecture and the manufacturing process will affect the day to day performance of the device, battery consumption etc.,it was never about the software but I know it everything comes to the OS how deeply it is integrated with the hardware and how effectively it co-ordinates with them...this is why Apple's devices are snappier than the android...the problem here is Samsung is more concerned about bringing more devices out than focusing on the system's deep integration...so it only comes to the fact that the thread is only about the hardware... but the discussion about the embedded systems is also welcomed....

[Q] Which Galaxy s4?!

I am really, really stuck in which S4 to buy, the Exynos octa core or the quad core snapdragon?
Which is better for everyday tasks?
Which is better for gaming (I am an avid gaming fan)? Is the powervr sxg544mp3 or adreno 320 better?
Speed, browsing and real world performance?
Finally, any suggestions on Roms and development on the phones?
Much appreaciated, thank you.
I'm going with the SD 600 because Qualcomm is very good at providing the source code for ROM development.
There really isn't going to be a huge difference in performance. The Exynos is slightly more powerful and comes with a Wolfson audio chip, but you're going to be limited to stock roms and incomplete AOSP roms until Samsung decides to release the source code. So if you plan to stay stock, get the Exynos. If you want AOSP roms, go with the Qualcomm.

I would heavily suggest the Qualcomm version. Snapdragons always seem to be snappier compared to other cpus, even though it has less cores. Speed and performance will be extremely similar, you shouldn't notice a difference between the two. The main reason to choose the Snapdragon is for the developer support. It will receive WAY more support as source code is always provided.

The "Source Code" as he is talking about is for the exerynos chip sets. They are Closed Source Drivers that Samsung uses/makes. They have never released source code for the exerynos. So for developers who modify the operating system to use MAINLY AOSP type builds they have to basically create their own drivers to get them working partially and quite often they do not perform as well as some if the hardware when using a Samsung based ROM that they were made for. The exerynos is awesome but it frustrated MANY developers to not want to bother trying to get things working any longer for the phones with exerynos due to the lack of documentation of the drivers source code Samsung made. I am sure I am not totally correct here with some of the terms and it probably could be stated better. This is just my layman's take on the issue...

Yes. It is one of the most powerful processors you can get now. For me though, the deciding factor between the two is battery life.

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.

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.

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.

Not true anymore. They are releasing an update to run all 8 cores at the same time to make it a true octacore

I thought they were. Wasn't it something like a Heterogeneous or HMP update.

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.

Should I get this Note 4?

I want a Exynos version of note 4, snapdragon 805 was kind of a disappointment.
http://www.ebay.com/itm/Unlocked-NE...1446740372?pt=Cell_Phones&hash=item1c46ca3194
This is on eBay right now, should I get it?
Questions:
1, Will there be a English option?
2, Will the phone be any different from the USA version?
3, If Android L come out, can I update it directly from the phone, or I have to do it manually?
4, Would I get 4g on Simple Mobile?(Simple Mobile is basically like T-mobile, they use T-mobile tower)
5, Do you recommend buying a Korean version?
Why is snapdragon disappointing?

Was hoping for a 808 or 810.
Snapdragon 805 is disappointing? Really? Exynos is better?

Well, is octa-core and 64 bit.
Saw a benchmark test between those two, exynos score a little higher.
If you were me, and price don't better.
Would you get snapdragon or exynos?

It's really never octal-core or 64bit. It mostly runs in quad core "mode" and is never in 64bit. Yes, it's capable of 64bit, but think of it like installing the 32bit version of windows on a 64bit machine. It's useless. Benchmarks don't matter. The exynos version is optimized for benchmarks, so it scores high in them, but is actually slower in real world use. Get the snapdragon.
From the benchmarks I saw, some of the exynos tests come up slower than Note3, some are faster than snapdragon note4, but IMO the biggest advantage could be 64 bit mode on Exynos. On the other hand who knows how is this 64bit Android going to work and when? Also make sure that radio is compatible with frequncies used in your area, what good is the phone if you get stuck on edge or have trouble making calls because half of the frequencies are missing? When I bought galaxy s3 couple years ago, it supposed to have LTE, but later it came out it didn't, there might be some similar surprises with Note 4 in the future as well.
Humm
Do you know the most reliable website to buy a unlocked Galaxy Note 4?

Such dumb replies. The S805 is great already.
Kitkat is not 64bit capable so its not using this feature now. Android L will be.

Yes..it is. Notice how the benchmarks are always insanely high but the performance is slightly slower?

First of all, You shouldn't tell opinions as True Statements...
Have you ever had any phone to compare by yourself ???
Samsung sttoped "cheating" in benchmarks since the Note 3, and it was mostly done in the QUALCOMM VERSION.

I never said they cheated anything. Its just optimized for benchmarks so people think its faster than it is (runs all 8 cores at one, but never does that in real use). I have used it BTW. I have a galaxy tab with an exynos processor that lags a lot pushing a 1440p display...same as the note 4. I tried a snapdragon one out in best buy and it didn't lag at all.
It is a true statement. That's like saying a Ferrari being faster than a civic is an opinion.

It is not, Samsung doesn't change at all their CPU from the "stock" ARM desings. So it is a pure Cortex AX. They don't this kind of things, Anandtech searched for that.
The Exynos 5420 has a weaker GPU compared to Snapdragon 800mso it normal. But don't say that the Note 4 lags as well becausw your tablet lags...

I said it would be slower, not lag. This is based on 3 generations of Samsung processors before. If they finally changed it to actually be competitive, good for them.
All of my other points are fully valid though.

Well I had good speriences with Exynos SOCs.
And my Galaxy Note 10.1 2014 with a Snapdragon 800 lags either.
