Only if apps are developed supporting both, but doesn't apple want to use only 64 bit?

Sure android needs to support nexus 6 minimum 2 years and it is running with 32 bit

[Galaxy Note 4 General] tmac31:
Nope here is the offical apple statement.

"Starting February 1, 2015, new iOS apps uploaded to the App Store must include 64-bit support and be built with the iOS 8 SDK, included in Xcode 6 or later. To enable 64-bit in your project, we recommend using the default Xcode build setting of “Standard architectures” to build a single binary with both 32-bit and 64-bit code."

They just want all apps to support 64 bit. 32 bit wont die soon.
[Galaxy Note 4 General] arjun90:
I strongly doubt Samsung will intend to make the current Exynos 7 in the Note 4 64-bit capable. That's just Samsung
[Galaxy Note 4 General] domy1985:
It really seems that Samsung does not use snapdragon 810 for the next note 4????

Here is a German article about it and it seems to be exynos 5433 with 32 bit?!

[Galaxy Note 4 General] herandy:
Again, as was said before only applications written with NDK need to be changed to support 64 bit. Applications written with JAVA don't need to change anything because they already support 64 bit. I'm not 100% sure about this but it's what I've heard.

P.S. Seems like the android runtime libraries should be changed from 32-bit to 64-bit by google itself, which should already be done by now.
[Galaxy Note 4 General] tploumen:
As expected, and as I told you all yesterday: Exynos 5433 on Note 4 stays 32-bit FOREVER.

So if you prefer graphics over a split second faster appload, you're better of with a Snapdragon 805.

Unfortunate for the people that did everything to get a SM-N910C.

Why you say that ? The games runs with no problem on Exynos, even so is a "split second" faster than 805
[Galaxy Note 4 General] hari smart:
does the note model n910c work in india??? I know that n910c supports fdd-lte only..... Whether 2g and 3g will work or not?? Is there any region lock in n910c model?? Expecting a clear reply
[Galaxy Note 4 General] lawtq:
Expecting a clear reply? Really? No offence but you should ask in a more humble manor and anyway its all there in many threads your answer. You might be waiting a very long time for this clear reply you're expecting. Maybe some kind soul we answer
[Galaxy Note 4 General] iba21:
Where should be the problem if our note will have 32bit forever?
[Galaxy Note 4 General] cooldoc007:
not sure abt region lock since i was using this model initially with a middle east sim.. 2G and 3G works normally.. currently in india for vacation.. i m not so sure if anyone reported the regionlock problem that was with note3

SM-910U vs. SM-910C ?

Both of above are Exynos but is there any difference between the two related to performance of SOC and battery as the link below suggests?

http://www.gamebench.net/blog/samsung-galaxy-note-4-beats-every-other-phone-asphalt-8

On Asphalt 8, both Exynos perform considerably well but the difference is just bit more to let go...
[Galaxy Note 4 General] a-kid:
I am curious and I hope this is the right thread to ask...Though I have read through a lot of XDA/WP threads on this matter and elsewhere on other Tech forums and have personally settled for the Exynos N910U as opposed to the SD N910G/S, I still can't find any solid, meaningful or conclusive results of comparison on Battery Life for the two different Soc variants on offer for the Note 4.

For me, more than CPU/GPU performance and benchmarks (which are all fine and good), I am really just interested in real battery life performance for the Exy vs SD, as a more important criteria personally.

So then, two questions:

has anybody come across some good meaningful articles/research on the net that looks into battery performance apple-to apple? I know there are a few that compared an Exynos Note4 to a SD galaxy S5, but its not the same i guess.

and since many of you guys here now have a note 4 of both variant physically at hand to play with for sometime, how do they stack up on battery life, Exynos vs Snapdragon?

personal opinion/experience anyone? and/or point me in the right direction for said article(s)!

Cheers.

[Galaxy Note 4 General] ps000000:
I wonder why SS make many phone with 2 (or more) different chips? :good:
[Galaxy Note 4 General] domy1985:
I can confirm the exynos version is much more fluid and the battery life seems to be slightly better, but I was just able to test it 3 days so it is just an impression I had about battery life.

Gesendet von iPhone mit Tapatalk
[Galaxy Note 4 General] midreestaj:
could that be because of one model has received latest updates and the other one hasn't ?
[Galaxy Note 4 General] tmac31:
It could be heat updates etc. Asphalt 8 runs 60 fps on my 910c. But gamebench can show 55 fps in average cuz when you are at loading screen its 1 fps or something so average score can be changed. But in game it is 60 fps and its generally not even drop to 59. So with 2 gamebench test you can see different average scores. You have to check in game fps yourself.

910u and 910c has different modem so it can effect heat and 910c couls be throttle more i dont think there could be any difference.
[Galaxy Note 4 General] 3dward87:
They are same, only LTE chipset differ (cat 4 vs cat 6)

Today my N910C arrived, hehe.. nothing for now to complain. I disabled all unnecessary apps, and battery is friendly.
[Galaxy Note 4 General] Nuu~:
I had both, the SD 910F and the Exynos 910C (Ericsson modem).

On WiFi the battery life was almost the same with the Snapdragon being slightly better. I got about 8.5 hours SoT on the SD and about 8 hours on the Exynos.

The standby battery life seems to be equal.

On 3G the Snapdragon lasted a lot longer.

I generally get 7 hours SoT on the Snapdragon whereas the Exynos only managed to achieve about 5 hours.

The standby battery life on 3G is also pretty equal. The SD lost 5% after 12 hours whereas the Exynos lost 6%.

The difference in battery life shouldn't be related to the frequencies my carrier uses as both models support the right ones.

The Exynos model's performance is noticeably better in games, browser and general interface scrolling and animations.

The Exynos microstutters a lot less compared to the Snapdragon. Though, it's still there on the Exynos too.
[Galaxy Note 4 General] yahyoh:
[MENTION=4167023]AndreiLux[/MENTION] what happened to the exynos version review ? does the new site owner dont want to publish it ?
[Galaxy Note 4 General] AndreiLux:
It was decided that there will be an architectural review of the new ARM cores added onto the article but the person in charge didn't manage to finish it yet and got delayed week by week. For my part I've been finished with it since 5 weeks ago and moved on to new stuff. Hopefully it will be out the week after CES.
[Galaxy Note 4 General] hung2900:
Thank you a lot for that. At least from my point of view the 3G modem in the 910C version sucks.

Is it true that the newer architecture is supported better than the old architecture in the future updates? It's true for GPU (like how Adreno 225 latter outperformed Mali-400 even intially losing), not sure about the whole SoC.
[Galaxy Note 4 General] charsta:
Yeah, I would like to know that too.

Because I'm considering buying a Note 4 and I'm leading towards to the snapdragon edition because of the community (custom roms and stuff).
[Galaxy Note 4 General] Lodix:
There are custom roms and kernel for both.
[Galaxy Note 4 General] midreestaj:
It is said that both versions of Note 4 have Sony IMX240 sensor for the camera part. But if we look on the Sony literature, product sheets etc. there is no mentioning of this chip. Would it be safe to say that Samsung got made a custom chip for the Note 4 line from Sony or may be Sony would commercialize the IMX240 on later stages when Note 4 has enough sold out ?
[Galaxy Note 4 General] jvtrigo:
I can confirm that my 910C has a Sony IMX240 but I have seen some 910C with an ISOCELL Sensor. I don't know why Samsung does that anyways.

---------- Post added at 07:49 AM ---------- Previous post was at 07:40 AM ----------

To know your sensor type in the dial pad #*34971539* and "ISP Ver Check" and it will show the sensor model if it is Sony you will see "SONY_IMX240_FIMC_IS" if you see something different it is an ISOCELL Sensor.
[Galaxy Note 4 General] daffie:
This code apparently doesn't work? I typed it in, nothing happened, then hit the Call button and this doesn't work neither.

Edit : nevermind...the second time it worked. My N910C has the Sony IMX240 sensor.
[Galaxy Note 4 General] jvtrigo:
Sorry...this one is the correct MMI CODE

*#34971539#
[Galaxy Note 4 General] daffie:
Cheers, indeed I had found the correct code already.
[Galaxy Note 4 General] midreestaj:
but the strange thing is IMX240 is not present in the Sony's products and literature ... Question is .. Why?
[Galaxy Note 4 General] jvtrigo:
I could not find any official Sony literature about it but it is listed in Wikipedia.

http://en.m.wikipedia.org/wiki/Exmor

Go to List of Exmor RS sensor.
[Galaxy Note 4 General] JNetwork:
Don't know if anyone already confirmed but N910U also has Sony sensor

Are you on nk5 update?

---------- Post added at 11:39 AM ---------- Previous post was at 11:36 AM ----------

What do you think aout this? 64 bit makes more heat or just another problem. I can say my 6 plus definetly heats more than my note 4 exynos. But different gpu modem etc ofc everything can effect the heat

http://www.androidauthority.com/snapdragon-810-overheating-issues-579284/
[Galaxy Note 4 General] bouzoubaa:
Yes. Nk5 for me.
[Galaxy Note 4 General] Azcaron:
Same here on my N910C - have NK5 update.
[Galaxy Note 4 General] AndreiLux:
Those issues are unrelated to 64bit. The S810 is just a bad chip.
[Galaxy Note 4 General] iba21:
Do you know where is the hardware thermal issue?

And.. what do you think about the nvidia project denver?
[Galaxy Note 4 General] midreestaj:
Is it possible that one 910C chip runs cooler than other? My 910C on 3C CPU manager shows always 4 Celsius lower temp while idling than my friends

Other difference is that my 910C keeps 4 of its A53 cores fired at 900 MHhz and sticks there all the time, (memory cleared, no rogue apps installed all standard apps which most of the android users have). My friends 910C idles at 400Mhz continously unless the screen is touched

What could be the possible cause for this? How do the cores behave in your 910Cs in this regard?
[Galaxy Note 4 General] JXulo:
Unless you work on Qualcomm you cannot possible already know that for just one or two benkmarks from a sample unit moths away from the final chip production.
[Galaxy Note 4 General] midreestaj:
Guys... help ....
[Galaxy Note 4 General] Lodix:
There are reports from TSMC that confirms that the Snapdragon 810 has some problems with heating.

Well there are different bins that make some chips run with lower voltage than others and therefore less heat, but it is not a big different.

It depends on a lot of things like signal, apps in background, etc.
[Galaxy Note 4 General] yahyoh:
its been answered many times , both version using sony imx240 the the kernel just dont show the the real name , so the only difference is the ISP

---------- Post added at 09:58 PM ---------- Previous post was at 09:56 PM ----------

so do u think the S6 will only use exynos ?
[Galaxy Note 4 General] grajesh83:
Please Help !!

iam really confused with these 2 options on choosing exynos or 805 chipset even after reading this thread.

Need direct answer for me please .

iam from india where N910G model is sold which is 805 chipset , also a 4G phone. I have a frd in UAE where N910C model is sold,Also a 4G phone. Can i blindly buy this from there to use in india ? will all go smooth in performance wise in chipset / network wise ?

Thanks
[Galaxy Note 4 General] Bruce lee roy:
Note 4 owns top 2 slots for best phones I'm the world
[Galaxy Note 4 General] JXulo:
From TSMC or from "annonymous" sources? If i remeber correctly is the second option. But even if TSMC said that, it still dosen't mean that 810 is a bad chip like he said. It only mean that they are facing problems and nothing else. Could be a bad chip? Yes! Can anybody here be certain of that at the momment? No! But if anybody know the future i want to know the lottery numbers of the next week :).
[Galaxy Note 4 General] iba21:
Well.. does it have heating issue? Is it real, well so it's a good chip since when the temperature is too low, you could take the phone in your hands to warm up those!!

It's absolutely usefull

So i decretate it's a very good chip!!

---------- Post added at 02:27 AM ---------- Previous post was at 02:23 AM ----------

all chips are different.. it depends on the puruty of the waffer and the productive lithografic processing

Anyway the dvfs logic is in the kernel and if you have all cores at 900mhz it means there is something witch teach to the governor to grow up frequency
[Galaxy Note 4 General] grajesh83:
Any1 pl reply for me !!
[Galaxy Note 4 General] midreestaj:
Need some further input from you guys in this regard; I did some more testing on my only 2 days old SM-N910C which is giving me strange issues. Its a brand new non-contract phone with full one year Samsung warranty. I am on the latest firmware PDA: N910CXXU1ANK5, not rooted, completely stock with knox on

The problem is that it crashes and freezes on benchmarks only. Yes, and all other operations are fine on this phone. First thing I noticed is that its smaller (A53) cores always keep fired at 900Mhz no matter what. Now Antutu started to freeze the phone for 10 seconds followed by a reboot. It happens on multi core Float test. Geekbench 3 also freezes the whole phone at exact 72% every time followed by a restart. Vellamo Multi Core test met the same fate. Here also as soon as the test starts whole phone freezes and then restarts. The interesting thing is that when I switch on Power Saver - all benchmarks complete successfully.

I factory reset the phone from stock recovery and repeat the tests without installing any of my own software to have the same results. Then I downloaded the Official firmware N910CXXU1ANK5 and flashed through Odin. This time again without any of my own software I just signed in my google account and downloaded these benchmarks. Same results; freeze & restart. Power saver On.. no problem then.

Can you please suggest me what is the issue with my brand new so much loved frost white Note 4 :(

Since it completes the benchmarks on power saver I doubt the issue kicks in when my A57 cores go faster than 1.6Ghz i.e. when the power saver is off. It comes down to whether the kernel which is included in the latest samsung firmware is not supporting the higher A57 frequencies with respect to voltages. Might that be due to unusual bin this particular 5433 has that is not covered by the voltage vs. frequency table? in other words a bad chip ?

Or there could be a flaw in the battery or voltage controller ?
[Galaxy Note 4 General] iba21:
It's strange..

Take the phone and use your warranty
[Galaxy Note 4 General] grajesh83:
any1 pl reply .
[Galaxy Note 4 General] midreestaj:
910C is generally a more interesting version of Note 4 than the 910G if you prefer 20nm chip arch since its a tech upgrade over the other. Other than that all other differences are subjective. That said, your choosing criteria should be based on the carrier on which you intend to use it. If bands are supported + your friend is getting a warranty on 910C then it is the recommended one..IMO
[Galaxy Note 4 General] JXulo:
i don't understand what are you trying to say, maybe being ironic i guess. Knowing the future is a very useful feature too but i don't have such skill like other members here.
[Galaxy Note 4 General] grajesh83:
Thanks for the reply ... Please find the difference n advice on buying N910C now when N910G is sold here in my place.

2G AND 3G (850, 900, 1900, 2100 MHz)are COMMON FOR BOTH

For N910G ::

4g lte(lte-a) frequency	700, 850, 900, 1700, 1800, 1900, 2100, 2600 MHz

4g td-lte frequency	2300, 2600 MHz

lte download speed	Up to 300 Mbps

lte upload speed	Up to 50 Mbps

For N910C ::

3g umts(w-cdma) frequency

4g lte(lte-a) frequency	800, 850, 900, 1800, 2100, 2600 MHz

4g td-lte frequency	--- NOT APPLICABLE

lte download speed	Up to 150 Mbps

lte upload speed	Up to 50 Mbps

Ppl says more than 2300Mhz reqd to make 4G work . Also Bands/Download speed in N910C are less than N910G.

[Galaxy Note 4 General] cooldoc007:
i bought my 910C from middle east and was using it in india.. no problems with networks at all.. could not test 4G as it was not available in my state.. but 3G/ GPRS was working fine.. and the download speed u mentioned in 910G doesnt matter as it rarely reaches peak speed.. can confirm with ur friends using 910g.. but warranty will be a concern if ur purchasing 910C.. price difference was around 13K.. so choice is urs..
[Galaxy Note 4 General] midreestaj:
80% of your decision should be based on whether the Network/s you are going to use support the bands in any of the two Note 4 versions in question. Like you have mentioned that for LTE 2300 MHz is required is a wrong statement. There is no linkage of 2300 Mhz and beyond to support higher speeds. You should also consider that LTE data rates are high. Due to this you are going to resort to WIFI anyway. Plus in India the LTE speeds I've heard are not even consuming 50% of the CAT4 capabilities so getting 910C or G would not make a difference.
[Galaxy Note 4 General] Kanth's:
Which is better for Devs???
[Galaxy Note 4 General] 3dward87:
Despites of all people who said Exynos will not have custom roms, is just a lie.

Both version will be customizable, and as I see more go for Exynos this time.
[Galaxy Note 4 General] sireniankyle:
I went with Exynos since the n910c works with AT&T's LTE network, and was cheaper than the n910f on Amazon.
[Galaxy Note 4 General] Schrotty35:
I will sell now my 910f and buy a 910c. I have lags with the 910f and i hope with 910c i have a smooth note 4.
[Galaxy Note 4 General] sireniankyle:
It is smoother, but there is still lag goin into recent apps. I used the n910a for a couple weeks, and hated the lag.
[Galaxy Note 4 General] karhariasgr:
so.. what is your final decision?

I'm ready to buy the gold one, but I hasitate about the CPU.. I read that the Exynos is better for users and Snapdragon better for develpments. I'm just a user and I prefer the stock rom, I used to change the roms with coocking roms in previous models but now Im bored of that. I just want a mobile phone to run everything with no lags.

That means I must look for Exynos version? Is the one with the C at the end of the model number?

Im confused... I wish to be only one phone in the stores, makes choise easier..
[Galaxy Note 4 General] Lodix:
If you want the best experience go for the Exynos, it is faster and have development too.

The Exynos is the N910C.
[Galaxy Note 4 General] rrmzr1:
Finally got a chance to play with my Bros exynos variant side by side with my tmobile snapdragon variant. They are exactly the same performance wise. I think I'll keep the sd805 just for the developer support. I'll trade the 3000 point an tutu difference. Thanks
[Galaxy Note 4 General] daffie:
...and don't forget the camera mods that are available for the SD version!
[Galaxy Note 4 General] POLO_i780:
+1

This is why I tell people to just get the one best supported by their country + network, as in real life usage there isn't any difference, many reviewers in Western countries got the Snapdragon and were blown away, some got the Exynos and a few had both, all seem to praise both.

Just get your Note 4 and enjoy this great beast :D

The Note 5 will be out in like 10months time, lol, and many of us will move to that, so no point in worrying about CPU.

I sure hope the Note 5 uses one CPU be it Exynos or SD, so all this stupid arguing over a chipset stops.
[Galaxy Note 4 General] darekz:
....and Gear VR support.
[Galaxy Note 4 General] rrmzr1:
That's all I'm saying. Reading thru this thread you would think that the difference between the two really stand out. And it just doesn't. And if there are any differences you would have to really nitpick to find them. games are very smooth on both. Where one lags the other does too. This thread is pointless lol. Anyone shipping a phone from another country just to have this chipset lol. Funny
[Galaxy Note 4 General] sireniankyle:
I got the n910c and live in the U.S.. Luckily, the phone came from Miami with free shipping. I got it, because

1.) I am on AT&T and the N910A suuuux.

2.) I wanted to try out the Exynos version since all I used up to this point was snapdragon.

3.) the Exynos MAY get 64-bit.

4.) I'm not big on custom roms.

5.) There is a difference in performance when running heavy games. the benchmarks did not lie this time.

6.) I like telling people that my phone has 8 cores. :D

[Galaxy Note 4 General] arjun90:
I don't want to be the devil's advocate, but the Exynos Note 4 will never get 64-bit support, sorry. :(

I had to bandwagon on the Snapdragon because of valid Warranty in the states.
[Galaxy Note 4 General] sireniankyle:
You really don't know that. It has a 64 bit chip.
[Galaxy Note 4 General] arjun90:
It has a 64-bit chip, but the 64-bit architecture is not enabled on the Note 4, it is disabled and cannot be enabled unless a developer goes in-depth about it. Samsung is only providing 32-bit support for the Exynos 7 on the Note 4. However, The Galaxy S6 will have 64-bit support enabled on the same SoC.
[Galaxy Note 4 General] sireniankyle:
So what makes you think a dev wouldn't? Let's not even cancel out Sammy doing it themselves. That could've been their plan all along. 64-bit is very much possible. Don't say it isn't just because it's not as simple as flipping a switch.
[Galaxy Note 4 General] RISHI RAJ:
We'll see in few days but i don't think samsung will discriminate in 64 bit thing & also their advantage of 64 bit S6
