[Q] Need advice , Which Note should I buy? Tad urgent

Ok
I've been debating with my self whether or not I should jump in and buy the note 10.1 2014 edition, but in my fact finding efforts certain questions arose ( with a lot of confusion)
1 Will HMP be available to the Exynos 5420 ? I keep finding information that goes both ways...yes...no...maybe
2 Does a root solution exist ( or is in works) that won't void warranty? (knox issues??)
3 Snapdragon or Exynos ( this brings me back to the HMP question!! IF HMP = yes well then Exynos, but...if not...?)
4 Any drawbacks when compared to comparable gen tablets? Lack of features, performance issues , instability etc?
I'm not doubting whether or not I want a pen enabled tablet, but with the new Nvidia pen enabled tablets in the works, samsung is losing it's unique position.
Now I know there are tons of posts all over the place that in essence answer a lot of the same points, but many of the threads go a bit back and forth and often misinformed on key issues...
Like Developer support for and against the Exynos vs Snapdragon etc And HMP support?
Now there is a small ticking clock attached to these questions, I've been offered a 17.5 % discount on the note ( LTE or wifi edition , my choice) But it expires on wednesday (30.okt)
Thanks in advance!!!
Cheers lads!

Short version, get the 32GB LTE version with Snapdragon 800.
Long version:
On current 28nm node forget about 8-core since it consumes too much power and runs too hot. Only possible once it hits ~16nm.
As far as stability Note series is best from experience. In over a year of owning Note 2 and original 10.1 have never experience a random reboot compared to even Google devices that have rare random reboots and other quirks.
For productivity and creativity there's nothing else right now that compares. If you want paperless note taking and drawing this is your best choice.
With high end specs and 3GB DRAM you're future proof for easily two years or more.

But why choose Snapdragon over Exynos? It's more reliable? Better performance? OR?
What about Samsungs talk about HMG capabilities on new gen Exynos?
Anyone know anything about the root question?

Snapdragon 800 has better graphics performance so that has bigger impact on user experience.
Forget about Exynos HMP for now until they get the node down to ~16nm as previously mentioned.
There's already root that doesn't trigger warranty negating Knox for Note 3 Snapdragon 800 which is a smaller Note 10.1 2014 Snapdragon 800.

Yeah l heard that snapdragon is 20 + % faster gpu. So there's that
But I can't help wonder how HMP (if it's going to be available to the note) would impact the performance of both gpu and cpu (I know that I'm a bit of a broken record)
Didn't know about the root, good to know, but there isn't one ready for the note yet...?
Anyone done a battery comparison between the two SoC ?
Anyone found articles on HMP and note? Looking for solid proof

As mention before the real problem with HMP is heat or should i say overheat and the battery life.
Do we need 8 core for real ?
It is simple i you need LTE/4G you have to go for SP version, otherwise buy the Exynos and save some $.

8 cores would in theory allow for better utilization of resources if we could get proper octa core. In essence if you're doing low yield tasks with limited needs, then you're using 1-4 of the A7's , if it's moderate then you switch to the A15 cluster, but if it's really demanding then the co-op between the two clusters might come in handy.
It would be great to have the capability available if possible, yeah it would be a drain on the battery, but think of it this way if you really need the power you're going to give up juice one way or another. The question is how smart the algorithms are to figure out your needs.
LTE isn't a must for me, it would be nice but I could go both ways on that issue. I'm more focused on performance, mod possibilities and overal performance vs battery balance.
What can I say I have a need for speed...

Lets be realistic no HMP for note3/10.1!
If you can afford the lte version buy it! But i don't think you gonna see a big difference. Real speed is one thing, benchmark is another one!
I believe the majority buys high-tech devices not because they really need them but other reasons.... i think we should enjoy more those devices and stop compering benchmarks.
Personaly i will buy the SP version cause i need 4G.

No offence taken :good:
Its not like its impossible!
Lets say that tomorrow sammy release the update that allows the 8 cores to work simultaneously, how can they be sure that the device after one month or year will not stop working... we already have read complains that some times the note gets hot.. They can't release a product that might break down every moment.. Imagine the loses the company will take in 2 year time (guaranty) plus the bad reputation.
P.S sorry for my English.

That is true, and absolutely something to consider. There is no real way to predict what effect HMP would really have on the CPU, and for that mater how much of a boost.
I'm just a tad pissed at Samsung for not being clear if / when/ what effect etc an HMP patch would have. In principle it might go fine, and the thermal sleeve on the 5420 might be able to take the heat. Maybe even the algorithms are in place to utilize the full effect and capabilities of the HMG tech. Or the whole thing might not even surface until Samsung S5 with Exynos 5430
I'm just stuck on the fenc, like any true tech geek the idea of true octa core is very tempting, and I'd be kicking my self if sammy Did release the patch tomorrow , but I already bough a snapdragon edition today....
Agony of choice is better then no choice, right?

If I've understood it properly, the OS takes about 4-5 gigs ( note that's the OS and the apps that come with it etc) , so in essence you should have something like 10-12 gig of user available space.
I'de say go for the 32 gig variant.
Yes, you can always add micro SD cards etc, but most apps still don't like moving to ext storage, and in most cases they don't move all of the content but just part of it.
I won't be gaming a lot, but a few games that I do like , GTA 3 and GTA vice city er about 2 gig each ( give or take) so there goes the space, some documents here and there, and apps, and so on and so on...
Anyone know of any difference in lag between the Snapdragon and Exynos versions?

[Q] Help Plz...........N9005(Snapdragon 800) or N9000(Exynos 5420)?

Hey guys finally the day has come when i will upgrade to a new smartphone and luckily as i am not short on budget i have decided to buy Galaxy Note 3 which i think is the best Android smartphone nowadays......the problem is that in my country both versions are available and i am not sure which version is better so thought what place would be better than XDA to ask this question......i hope you guys will help me in taking the right decision.
Btw N9000($605) is about 30 usd cheaper than N9005($635) which though doesn't matter but i thought i should share this as well with you guys.
(Both are 32 gb variants)
Regards..!!!

Just watch the N9005, trick little prick if the service provider you're using is on bands 7/17, however the 9005 is a little better hardware wise! I personally don't think you'll noticed the difference!

Go 9005.
Firstly, Exynos only excels more in graphics department and its barely any better then what Snapdragon offers. Also the SD model is more widely available & the carrier choice due to FDD-LTE, Which means better longterm rom support between the two models.

N900 has 2.66 GB of total RAM
N9005 has 2.38 GB of total RAM

n900 exynos doesn't support 4g LTE, hardware issue.

dont worry about the ram difference....they both have 3GB...its how each of the 2 versions reserves certain amounts for the gpu & other systems processes....(not sure of the EXACT things that do this....but i read it here in xda while deciding on the note 3 version myself).... but in my opinion i would suggest you go for the n9005....its a little better in terms of performance...as far as battery is concerned the snapdragon is better as my cousin owns a octa version & mine does considerably better....it has LTE & it has 4k video recording & playback support...something the octa version doesnt....so that means the n9005 is a bit more futureproof than the 9000 PLUS the n9005 has a more active developer support....

N900 is Exynos Variant which means the processor is developed by Samsung. The N9005 is Snapdragon Variant which means the processor is developed by Qualcomm. Overall I would prefer the Snapdragon 800 Variant as performance is much more excellent than Samsung's own Exynos.

The last line can be a deal breaker in favor of N9005 as it would be very difficult for me to go for the variant which has considerably less developer support.......so as of now i am leaning towards N9005!

Btw i read somewhere that Samsung might release a patch which will enable all the 8 cores on N9000......is this true can anyone please confirm this?

Most Exynos users including me are suffering from poor battery life. N9005 users seem to enjoy 9 hours of screen on time, while me and some other N900 users get 4-5 hours maximum. So I'd say go with N9005.

And i thought that due to those 4 power saving A7 cores N9000 will have the better battery life lol...........thanks mate for telling me about battery life coz this is one of the primary things which i look for when choosing a smartphone..!!!

On my personal usage I had both snapdragon and exynos and eventually end up with keeping exynos for myself and gave snapdragon to my sis as exynos felt a bit snappier overall to me but in few games snapdragon had a slight advantage but the exynos was no less in some games exynos was better, and yes battery sucks with latest firmware update was excellent before so you can expect battery to be fixed with updates and if you have LTE in your country go with snapdragon, exynos makes no sense if you got LTE in your region and better development also goes to snapdragon, also today Samsung might announce something about their exynos processor @Ces and my guess is they will release the hmp which enables all 8 cores, though nothing sure keep an eye, so decide what you need, but in terms of performance pick either of them you wouldn't regret

sorry but the HMP patch to run all 8cores have been scraped a while back...so performance wise snapdragon is better...plus i have 2 exynos variants of samsung products at home...an s4 octa & a note 3 octa....dont know the reason why...but they started to bog down after a few weeks of usage....there arent many apps installed on either device, both rooted by me & debloated & running almost the same setup as my n9005...but mine is still as snappy as it was the day i got it :/ ....the current 5410 & 20 were experiments if you ask me.... i'd say the n9005 is the nobrainer choice when buying note 3

The devil's advocate
I'm surprised No one's mentioned how hot the snapdragon version gets under stress! I've never had a handheld device get so hot! No exaggeration, I sometimes worry if I should stop what im doing to allow the phone to cool. My friends exynos note 2 doesnt even get warm. I can attest to the battery life, atm I get 10hrs screen on time which includes reading rss feeds, music and light to medium web browsing. I was always under the impression the exynos version was better on battery, but some users seem to suggest otherwise. I bought the n9005 instead of n9000 because: 1. It was cheaper in my region.
2. To use LTE.
I dont regret buying the snapdragon version, but the performance difference between the two is negligible and the heat
issue really bothers me, so i must vote for the exynos, providing that the battery life isnt noticeably worse.
oh one more thing.. 3g+ is still quite fast and 4g lte is a battery hog, though the speeds are impressive.

Go and have a [email protected] on Twitter, and you'll find something as #UnlockExynos which as assumed can be related to HMP, also if there's no HMP I wouldn't really care, I find the 5420 still great, and yeah galaxy s4 5410 that was a serious fail, I threw it out in 2 days of usage coz that 5410 processor was such a bullshi* but that isn't the case with 5420 but still it's own preference and way to think which is good or bad.

http://www.gsmarena.com/samsung_galaxy_s4_and_note_3_wont_get_true_octacore_update-news-6908.php there mate....that unlockexynos thing that you speak of is probably the processor teaser for S5 which could be 64bit processor.....& S4 octa processor is the absolute pits.....the note 3's octa is a slight improvement...but i would still say the snapdragon is a better overall package....& thus a slightly better choice

sorry mate...but you may have gotten a faulty unit...as my snapdragon barely ever gets hot.....i played real racing 3, gt racing 2 & asphalt 8 nonstop with 100% battery until i drained it to 0% & the phone barely got warm....& as for battery life.....the snapdragon is quite a bit ahead of the exynos...i have 1 in the house so i can tell....also the performance difference may be negligible but its still visible...atleast to me

Exynos 8890 or SD820?

I will buy a galaxy s7 edge next week, but for now in stores only the exynos version is available in my country. Is it a good soc? Or should I wait more for the snapdragon phone?
On my note 3 the exynos chip was considered pretty bad, on both performance and battery life.

Exynos = Better CPU, Battery drain mostly from radio cell.
Snapdragon = Better GPU. Battery drain mostly from Android system (not sure is it fix able by update. )
If you're that person that love installing AOSP ROM. Snapdragon is your choice.

I will definetly root, most likely on day one, but I doubt I will be using AOSP roms.
Gaming on a phone isn't for me as well, I have my iPad or ps4 for that.
So the exynos runs better for day to day tasks?

For day to day tasks, there's no difference

For me I would prefer SD, cuz the ROM, kernel and mod development is much much better and I'm a flashaholic but in Europe only the exynos is available. And I'm scared there won't be so much to flash\development...
Am I right? How was the ROMs, kernels ect. on s6 edge exynos? Will devs come support us?

If your in Europe then it's not worth the hassle to get the snapdragon version IMO. That being said, the snapdragon has the better GPU, modem, higher single threaded performance, and more than likely a better ISP, DSP, etc and other blocks of the SOC. The exynos will have better multithreaded performance, just due to the fact that it has 8 cores vs the snapdragons 4, even though per core the snapdragons are faster. Like others have said developement will be noticeably less on the exynos. You will still get custom Roms but I wouldn't expect cm or aosp within a year, or ever. In dqy to day performance I would expect the snapdragons 4 very fast cores to be more responsive than the 4 slow cores and 4 fast cores of the exynos, especially considering most of the normal ui is processed on the slow cores and has to migrate to the fast cores when it needs it.

What is your basis for these arguments? Seems like most people in this thread are just making stuff up without quoting any real-world tests. Even Anandtech stated that the SoCs are pretty much equal (as far as they currently know, and they have already written pretty extensively about both SoCs), and that efficiency is what is going to set them apart. I wouldn't draw any conclusions without actually reading a comprehensive comparison of the two.

I just pulled the trigger on an Exynos version, despite living in the U.S.
Reasons you might consider the Exynos over the SD820:
1) LTE Bands, the Exynos version has far more LTE Bands for use around the world. If you travel around a bit, then it makes a bit of sense to have a phone that can receive data, regardless of the network you're on.
2) Battery drain: it looks like both SoC's are plagued with one thing or another that saps battery life, but the SD820 has an alarming amount of drain from the Android system. It still has great SoT (screen on time), but it's still a worry nonetheless.
3) Carrier lock: If you find yourself on one network, then this shouldn't be an issue. But within the past 2 years, I have been on a AT&T, then a business T-Mobile line, then Google Fi, and now on an AT&T business line. If the phone locks to a carrier, then you might have to wait longer or pay to get it unlocked.. which can be a drag.
That being said, I'm sure the development for the SD820 version will be immense. However, I'm coming from a Nexus 6P, and feel like the stock S7E ROM performs so well, that I won't need to root or anything. Android has reached a level of smoothness that was not found on earlier versions, especially in tandem with TouchWiz of old (older Notes and S phones were laggy, really). So stock ROM with the ability to use Android Pay/Samsung Pay will be nice.

I just pre ordered the UK S7 Edge, hoping it'll be Exynos.
In the benchmark thread people are getting virtually identical Antutu scores across chips. It looks like the Snapdragon is throttling earlier than the Exynos though, they always have ran hotter.

In singel core performance, the SD is a few % better. But in multi core, the exynos is about 20% ahead. So it does seem to run better with the CPU. Also it seems to run cooler, so throttling should be better.

We need someone to run consecutive 3dmark runs on the exynos in order to know whether the gpu throttles or not, and if so after how many runs. We already know neither will throttle the cpu in geekbench, but the SD820 throttles the gpu a bit after two 3dmark runs.

Yes we should await further testing. Since the SD is released in America for some already, the benchmarks for exynos are hard to find.

I'm pulling this from past experience with exynos 7420 kernel development, and every article ive read on the 820 and the exynos 8890, in addition to benchmarks on both and my own device. Qualcomm leads the world in modem technology. The one in the 820 supposedly has achieved parity with wifi. In addition we have the hexagon DSP and spectra ISP all of which can operate in a sort of HMP configuration to accelerate tasks. I would find it hard to believe that Samsung has caught up to qcom in these misc blocks of the SOC. But that's why I said most likely for that portion as I'm just making an educated guess. Single threaded performance is quantifiably higher on the snapdragon, all the benchmarks shows this, just as they show that the 8 core exynos scores higher in multithreaded scenarios. The rest about development etc is because Samsung doesn't release the proprietary hardware blobs we need to get a proper aosp/cm port working. Meaning we have to write them from scratch which takes forever. Qcom has always provided these in the past. The GPU also performs better in benchmarks, whether there's a noticeable difference in real life remains to be seen, still from all evidence the snapdragon beats out the exynos GPU. And my experience with the 7420 taught me that the small cores can have trouble keeping the ui smooth at all times, and we see the same cluster again on the exynos, only on a slightly improved node. Hopefully this explains the logic behind my post better.

Could very well be that the sd820 endas up faster than the exynos 8890 in day to day tasks, but the sd820 seems to be using a lot of mW in comparison to other SoCs(check anandtech's look at the mi-5). Its single thread performance is better, but on average there's only a 10% difference and the exynos is clocked lower than reference (2.7ghz and 2.4ghz). Both modems achieve the same speeds so the only thing that is going to matter in the end is efficiency. Still need to take a look at the GPU throttling on the 8890, as we only know the sd820 GPU throttles at this point in time. Personally I would have preferred the sd820, but if the 8899 brings better battery and better audio quality the difference in performance is worth it. Looking forward to anandtech's in-depth comparison! Don't really get why we haven't seen any reviews yet even though people have the phones already.

Also awaiting the deep dive on both. Keep in mind though, that 2 of the 820s cores are clocked at 1.6 and have less l2cache to save power, and 2 of them are at 2.2ghz, so clock for clock they have very high performance. As for the power draw comparison, it was only an estimate to begin with, and ones got 4 little and 4 small and if it was only using the 4 small during the test that alone would be a noticeable power draw difference. It gets pretty complex with these big.little setups. I've also noticed the snapdragon version has a pretty high load average which should be able to get lowered with some modifications to the kernel.

Reasons you might consider the Exynos over the SD820:
1) LTE Bands, the Exynos version has far more LTE Bands for use around the world. If you travel around a bit, then it makes a bit of sense to have a phone that can receive data, regardless of the network you're on.
2) Battery drain: it looks like both SoC's are plagued with one thing or another that saps battery life, but the SD820 has an alarming amount of drain from the Android system. It still has great SoT (screen on time), but it's still a worry nonetheless.
3) Carrier lock: If you find yourself on one network, then this shouldn't be an issue. But within the past 2 years, I have been on a AT&T, then a business T-Mobile line, then Google Fi, and now on an AT&T business line. If the phone locks to a carrier, then you might have to wait longer or pay to get it unlocked.. which can be a drag.
That being said, I'm sure the development for the SD820 version will be immense. However, I'm coming from a Nexus 6P, and feel like the stock S7E ROM performs so well, that I won't need to root or anything. Android has reached a level of smoothness that was not found on earlier versions, especially in tandem with TouchWiz of old (older Notes and S phones were laggy, really). So stock ROM with the ability to use Android Pay/Samsung Pay will be nice.

Yup my SD820 is running full on SPay, Bluetooth, WIFI, NFC, Always On Display all without power saving mode and I get 8h SOT in 24h. Listening to a few posts of people beginning to learn the phones quirks within the first few days is not evidence of anything other than the phone being broken in. Spreading information like this gets people buying devices for unsubstantiated reasons. Please provide evidence if you're going to post stuff like this. You guys are just starting an echo chamber quoting each other with no evidence supporting your rumors.

I never believe people when they say they get 8 hours of screen on time.
And if you read my post carefully, you'll see the fact that I stated the SD820 still has great SoT, but just that there are issues with the Android system draining an alarming amount of battery percentage. This is not some baseless claim, there are multiple posts in the battery life thread showing the android system taking up 35%< of the battery.
Edit:

In case you were wondering which thread.
Again, it's just a strange thing that can maybe be fixed by a software update.
And while we're at it, how about you show screenshots of your supposed 8 hours of SoT?

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?

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.

S10+ Exynos or Snapdragon?

Which of the two should I take?

Snapdragon as i have exynos and i have seen many comparisons in which Snapdragon is ahead e.g. Snapdragon has better battery and performance

If you want to root, then Exynos. If you don't care about rooting but want overall (midly) better performance, get a Snapdragon.

I dont think you will notice any performance gain or loss at all, but SD has slightly better performance, yes.
Other than that, I've seen people saying that SD has better battery life but head out to the battery optimisation thread. Exynos' battery can last over 15h SOT and I have not seen SD users come close to that.
Exynos users have a dedicated and improved night camera mode for about a month but SD models dont have it until now, but certainly will get it soon enough - I guess it's easier for Samsung devs to work on Exynos models, but other than that both have exactly the same features working amazingly.

Snapdragon is better than exynos in every cases. SD models have also camera imx sensor which is tottaly better than isocell sensor from exynos.

I think Snapdragon variant is a much better buy as it is advantaged in many ways. Battery life, performance, camera, gaming to name a few. Also the SD is built on a newer more efficient architecture.
Samsung should just drop the Exynos all together and just stick with Snapdragon

I'm good with the S10 Plus Snapdragon! But, I did like the Note 9 Exynos variant.

I've had both versions and the only difference I've noticed was that the SD version had better battery life. Testing may show that one variant may be faster than the other, but it is not really noticeable in real-world usage. But the better battery life is definitely noticeable.
