Hi guys,
I am going to buy the Samsung Galaxy Note 3 soon. However the variant which is available to me is the N900 with the Exynos 5420 processor.
The thing is that, I am a bit confused about the GP. It is running a Mali-T628 MP instead of the Adreno 330 on the N9005 models. Will I notice a visible difference in gaming? Is the Mali that bad against the latest Adreno.
Also, do you think that the HMP patch that Samsung hinted at, to unleash the true 8 cores might affect the GPU performance later on?
The processor is the only thing that is stopping me from getting this variant. Please guys, help me out on this.

Adreno 330 is so good but
Mali in note3 is Octa GPU and clocked higher than adreno 330 (u can find and compare by wikipedia)
both of them are so powerful however adreno shows more score in graphic benchmark but it s not that high but cpu in exynos is about 2000scores more than snapdragon (in antutu benchmark)
anyway u won't lose anything if buy snap or exynos both of them are awesome
:good:

Battery life on GS6 on Exynos 7420 (14nm) was terrible even worse than on Snapdragon 810 (20nm).
Because of faulty ARM design BigLittle.
Disappointment level in terms of battery life was almost the same.
In 2016 new Exynos 8890 apply the same faulty ARM BigLittle architecture as for the Exynos 7420 last year.
Qualcomm with SD820 applying new custom quad-core architecture.
In Europe we get offered only the old one infamous BigLittle architecture.
What do you think about?

Why worry about such things at this time? Nobody reviewed it. And big.LITTLE is not faulty. Kirin 950 is doing pretty good with that. Any batterylife issues in S6 was not due to SOC, but wakelocks and standby times. Anandtech reviewed 7420 extensively, and they said it was the best SOC at that time. If big.LITTLE was faulty, you think these thousands of engineers would not have changed to something else by now??
Also it's not CCI-400 interconnect this time, Samsung using their own interconnect. So before testing anything don't draw conclusions.
And as @omeryounos mentioned, there is already a battery thread open. Discuss there.

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.

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.

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

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.
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?

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.

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.
