Z5 is rendering in 1080p so there's no surprise it comes ahead in onscreen benchmarks. The mali-gpu is also not the strongest. Pretty sure the 820 will perform better.

LG G5 seems to be scoring almost 20k higher than the exynos 8890-equipped S7. S820 looks to be the better SoC by far at this point.

To sum things up: the Snapdragon 820 sports a better GPU, the Exynos 8890 sports a better CPU and a better DAC (Qualcomm DACs just haven't got the best of reputations, while the Exynos usually sport a decent Wolfson DAC), Qualcomm SOCs however usually sport a better baseband/radio than the competition.
I would say, in daily usages, the performances should be negligible, the real impact between both should be battery life related, an early preview done on the Exynos 8890 version claims a 12hrs battery life at maximum brightness on the S7 (not the S7 Edge), I guess we will see how it goes when more reviews come in.

No Wolfson this time. It seems Samsung is using an in-house DAC.

another benchmark between sd 820 and 8890:
www.anandtech.com/show/10075/early-exynos-8890-impressions
i hope the 4 core difference between the two doesn't mean worse performance on the sd 820 variant. Also if you in the EU you will -apparently- be getting the exynos variant :crying:
i also read somewhere that said that the sd 820 had 2x custom (kyro) a-72 cores and 2x custom (kyro) a-53 cores and not 4x cutom (kyro) a-72 cores, hope its not true.

Quoted from the comments of the article at AnandTech linked above:
It seems perfectly competitive in the graphics benchmarks, and comparing JavaScript benchmarks across different hardware, OS, and browser configurations is useless. To say Apple's Safari team "aggressively optimizes" for Octane and Kraken would be an understatement. Plus we're talking about simple benchmarks that can barely make any use of a second processor core, so of course they make the A9's dual-core CPU design look good next to more parallel competitors. Run something like Geekbench MT or the 3DMark physics test and watch A9 lose out to even Exynos 7420 or SD 810.

The s820 has two custom cores and two lower-clocked A53s. It really won't matter that it has two fewer larger cores, as more cores leads to more heat, and more heat to more throttling. Only in benchmarks will it be noticeable.

Where did you find that the 2 lower clocked are indeed A53s? What I have read, SD820 has 2 high clocked 2.15GHz and 2 low clocked 1.59GHz "Kryo cores"? So those 2 downclocked Kryo cores should be A72 like power not A53?

Hmm not sure, but pretty sure they aren't the same cores as the faster ones, as that way they could just have clocked them higher, and have them downclock instead of having them at 1.59Ghz all the time.

Says the test ran for 220 minutes. EDIT: Okey that was the results of the battery-test. But still where did you get 10 minutes from? If you look at the graphs you can clearly see that it dips only once to 1400 and that was at about the 1200 second mark (20 minutes).

Its probably fake as most of the score comes from GPU which is impossible and then theres 1080p vs qhd screen question
Sent from my SM-G925F
Throttling looks much better compared to 7420.
They have made GPU wider and lower frequency, also better manufacturin process. Bound to get better compared to 7420.

Yes, in latest version of Antutu it gives more priority to onscreen numbers and single core performance. That's why iPhones are at top of chain in Antutu
So the Qualcomm Snapdragon 820 is quad core. Why did Qualcomm decide to go with a quad core one over a octacore or hexacore? How would that affect the GS7/GS7 Edge if it were octacore or hexacore? How much of a difference is there between the Exynos and 820?
Indeed the snapdragon 820 is a quad core SOC unlike most recent socs which have featured 8 cores (2 clusters of 4 cores). However most big.little socs like the exynos 8890 and 7420 use 4 low power slow processors and 4 high power, but power hungry processors. They are completely different architectures. This means that while the exynos 8890 for instance has 8 cores. Only 4 of them are really designed for performance. The other 4 are designed to save power. The 820 is different. It's also some sort of big.little setup with 2 clusters of 2 cores. However both clusters are identical architectures. The difference is one cluster is clocked lower and has a different l2 cache configuration in order to use less power. On top of that the custom cores in the 820 are faster per core than the exynos 8890. So clock for clock the 820 would win against the high power cluster of the exynos. In heavily multitheaded situations though. The exynos still can tap into all 8 cores at the same time which should give it an advantage in that scenario. For the rest of the time I would imagine the 4 faster cores of the snapdragon would be better suited to everyday stuff. As for why they only went with 4. My guess is cost, and power efficiency. Kyro is a brand new architecture. Krait went through many iterations. Kyro will probably see a noticeable reduction in its power envelope in the next iteration which would make shoving more of them onto an SOC a more viable option. As for gpu, all signs are pointing to the snapdragons adreno GPU beating the Mali in the exynos atm. Development will also be improved on the snapdragon device as Qualcomm releases the proprietary vendor binaries and Samsung does not. This means the likelihood of seeing cm or aosp on an exynos variant is slim. Hope this helps!
Actually, the Kryo cores are (slightly) better at running single threaded tasks while the Exynos cores are (slightly) better at running multi-threaded tasks. I doubt the everyday users will notice.
The Adreno is also more powerful than the MALI GPU, though everyday users will mostly notice a performance improvement on applications using the Vulkan API vs regular applications, than anything between both these GPUs.
Finally the memory management seems much better on the Exynos 8890 for some reason (about twice as fast), since the same chips are used I wonder whether it's a software or a hardware implementation difference, both units are plenty fast though.
The real difference between both these SOCs will seen in the power management efficiency, in fact both variants are overpowered in every aspects as far as regular usage goes, so there is little point in comparing which one's the fastest. Instead, you need to wonder which one is the most conservative with power consumption while achieving equivalent performances.
Both the GPUs on these SOCs support the Vulcan API. And, whilst the Adreno is faster in terms of pure benchmark numbers, I very much doubt there will be a noticeable difference on any game or application, Vulcan or otherwise, that will be released during the lifetime of these phones.
Yeah, that does help explain it. Thanks. I just hoped there wouldn't be a TSMC vs Samsung difference in the iPhone 6S/6S Plus SoC.
i was thinking 8 core snapdargon 810 was over heating and thermal throttling so they went for 4 cores instead on snapdragon 820.
just my thoughts.
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.

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:

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?

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.

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

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.
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.
