Qualcomm to update the Snapdragon 810 CPU for Samsung
Reports that the new Snapdragon 810 chipset has been contending with heating problems has not stopped all OEMs from getting on board with the new octa-core 64-bit silicon.

LG was the first manufacturer to announce it would be using the new system-on-a-chip in the new LG G Flex 2. The company said it was able to work around the chip’s heat emissions. While that is arguably a good sign, it could also be seen as an acknowledgment that the Snapdragon 810 runs hotter than some would prefer.

The issue has been the source of reports that Samsung was forgoing use of the new Qualcomm chip, in favor of its own Exynos CPU for the next generation Galaxy flagship (presumably called the Galaxy S6). However, it looks like Qualcomm is working on a redesign to address the heat emission issue and should have a solution for Samsung by March.

It is not known if that will be in time for Samsung’s plans for manufacturing its new line of devices in 2015, but Qualcomm is undaunted since the Snapdragon 810 is obviously an integral part of the chipmaker’s strategy.

For its part, LG has stated that heat levels are not solely about the CPU, but how a device is also designed to dissipate that heat. The company noted that the G Flex 2 was designed with the Snapdragon 810 in mind, so heat levels have remained within what LG deems optimal.

There is some conjecture by analysts that Samsung may use this opportunity to provide wider distribution and use of its Exynos CPUs.

Lg just throttles the chip if the device runs hotter. Also it limits the brightness.

The snapdragon 810 heats up and even if you dissipate it, it results in loss of energy and hence bad battery life.

Well, looks like I'll have to look out for phones with liquid heat-pipe cooling. Or skip 2015 all together and wait for Krait's successor :/

I'm just hoping the exynos 7420 is awesome along with the s6. My s4 is getting long in the tooth and its screen is cracked. I need a replacement and can just hope the s6 delivers it.

I have no hope with m9 or z4 as they will have this overheating non efficient chip.

P.S. Even the liquid heat pipe cooling just distributes the heat. It doesn't dissipate it. So the heat still remains in the device but spreads more evenly. And it still doesn't help the energy loss due to heating

I exchaned my sd805 note 4 with exynos note 4. Sd805 has better battery life as compared to exynos. Exynos is eating battery very quickly, battery performance on sd805 was great. Moreover, sd805 has better graphics performance(as I am feeling it) bcoz zombie assualt:snipper is having black back ground which was fine on sd805 model. However, sound quality is better on exynos model, same songs which were producing less beats are now having more beats in the sound.

So I think, Snapdragan still has an edge on exynos... but may be over heating will detoriate everything in sd810

Then ur exynos note 4 must be defective.. I have compared both phones almost side by side.. Exynos note 4 has better battery life and is most of the time visibly faster than the sd805 version.. While i still have my sd805 note 4(exynos one was my brother's) i ll say that both versions are great, however when u compare them, exynos has the edge.

May be, lets see its just a faulty battery or something. For performance, both are equally fast. I have'nt feel any performance difference yet(its just 3rd day of having exynos). Real results will come out after a month or so when I will clutter the phone will plethora of apps, songs, movies etc. In my hands each & every phone slows down after sometime(only haters complain about touch wiz).
In sound quality I accept exynos is producing better sound and about other stuff I didnt observe yet.

Can you please install zombie assault:snipper on exynos to check whether it is working fine or not? If it is fine then my unit is faulty.

Also it could be your country
The Exynos models weren't design for the US
So the radios use more power in the US
Hence why some US reviewers said the Snapdragon had better battery life

It's surely your radio. Even MKBHD reported that the exynos isn't optimised for US carriers. Watch his note 4 review. You should've stayed with SD 805 in US.

Your unit is not faulty, it's just that your region doesn't have bands exynos is compatible with. And it has to work extra hard which is draining battery too much.

I have proofs that the exynos note 4 is better in every way.

iam just surprised of u say i can insurre u that there is nothing of this is true at all i have exynos note 4 and let me tell u its more power efficient than SD805 and also in gaming i want u to check out GTA san andreas in both versions as an example u will find it running smoothly on exynos more than SD805 and other games like aspalt 8 don't compare exynos 7 octa with SD805 compare it with SD810.

How I can compare with sd810? There is no note 4 available with sd810. I can only compare with what is available and I have used. I have used sd805 for one & a half month and now using exynos from last 2 days.

I dont play GTA and asphalt type of games. For The walking dead, wolf among us, games from artifix mundi, I think much horse power is not required and we cannot feel any performance difference in this type of games. I just felt the difference only in one game so far, that is zombie assault:snipper(low graphics game). It was working fine on sd805 but all the details and back ground is black out in exynos. Thats it!

Snapdragon 820 with Taipan architecture should be out by the time the Note 5 arrives :)
Skip anything with an 810.

Glad I got my Note 4 with 805, I knew the 810 was going to be a rushed stop-gap, the 820 will be the SoC to have.

I am pretty sure Qualcomm won't release 820 in 2015. The 810 was announced in q1 2014 and is released now. There is no way the 820 can be ready now. I even doubt that the 815 will be ready in 2015.

I would go for exynos this time. Qualcomm is too lazy and blind in its monopoly.

Yup, they rushed last year with QHD on snapdragon 801 which was a bad decision as it leads to lags and poor battery life. And this year they're jumping the gun too fast.

Samsung has a fallback plan with exynos and they'll adopt it rather than overheating faulty chips.

Says an I'll informed human being. I've had the G3 for many months since it came out, and batter does not auxk. Lasts two days friend. They never rush anything, they are confident and it shows in their products. First company to have the ultimate battery life and the first to put a different button arrangement on their phone. Not to mention closest to having almost no bezel. Haters gonna hate

expect SD 820 at MWC 2016, not before that

qualcomm is lazy and slow ,

for note 5 , they'll simply roll out an overclocked Snapdragpn 810 and rename it to Snapdragon 811/812

Go figure.

It was damage control, I don't blame them but they should have halted production or admit a poor binning before production unless LG accepted that notion.
Which is looks like they did.

Samsung took the media hit on the chin, kudos.
LG, skip this year.
HTC might be pass too.

Actually if Exynos 7420 is to be 14 nm, as it is said in all the sites though, then Exynos 7420 will put the newest S810 to bed. But if the Exynos 7420 is to be 20 nm, then an "improved" S810 will beat it of course
Let's wait for actual announcement or official statements from QC and Samsung ....

I guess there might be an undergoing version produced for the second batch or even third batch of the production. To be safe, don't get the devices with SD810 immediately.

Quite simple, due to Apple using an older and far lower screen resolution iPhones don't require the power, it's not that they are well optimized, the Note 4 and S5 run rings around the 6 Plus and 6 in battery life, also the fact that the Samsungs have true multitasking being capable of running multiple windows they require the power, while the iPhone uses 1GB RAM as it freezes apps and isn't as productive.

Cheers! :)

What do you mean by "true multitasking"?
Would you say an iPhone, running 50 apps at the same time, doesn't do "true multitasking"?

It's not definitely not running 50 apps at the same time. When you pull up that app switcher on ios those apps are froze and have to reload. When he says true multitasking he means looking at 2 or more apps at the same time and being able to have said apps being able to work with each other.

It doesn't run them at the same time, it suspends those that aren't in the foreground, and picks them up where they left off when they're brought back to the front.

It's c++ vs Java.

Java works great with multiple weak cores and c++ requires more single threaded performance.

iOS uses c++. Hence Apple has to go with dual or triple cores. But one core of Apple is twice as powerful as one core of these snapdragon or exynos ones.

I'm typing this from an iPad air 2, so don't consider me as Samsung fan or anything. Both ecosystems require different kind of processors.

Samsung isn't building quad cores just to run their UI. They're shipping quad cores because they can: Android has full fledged multitasking and can use them. Just for kicks, I had 15 apps open and running on my Note 12.2 the other day, all on-screen. They're also pushing around significantly more pixels than Apple. And of course, Apple doesn't currently support full multitasking, so they don't really have full use of two cores. Except on the new tablet... I think they're planning to enable two apps at once, probably as a split screen like Microsoft, at some point. Also probably why it has two 8 core GPUs rather than one 16-core GPU.

And while Apple's two CPU cores certainly can get hot, it's their GPUs that really suck the power. They are preoccupied with gaming.

This is the time for Samsung to pull ahead. Tegra will never make into popular mobiles and Qualcomm will struggle with the big.LITTLE architecture, not to mention the ditch of Krait to Cortex-A57, switch to 64 bit and to ARMv8, too much at one time. Samsung can produce 14nm SoCs with a refined big.LITTLE implementation (that took 18 months to work out) and can do it with integrated Cat.10 LTE modem and possibly it's own GPU down the line. It could compete with the Apple A9 chips, also mostly made by Samsung. This could mean either Exynos domination in the Galaxy line-up or even selling the chipsets to other companies, and why not. The 5430 does spectacularly in the Alpha and the 5433 is more efficient and heat-friendly than the SD805 in the Note 4, and that's just on 20nm.

It's time for every SoC maker to bring their A game and that means Intel's x86-64 along with imgtec's MIPS as well. Qualcomm got themselves into this mess because right now they're a near monopoly at midrange to flagship range outside of the iPhone sphere so unfortunately the usual "top of the hill" syndrome has apparently kicked in. What most people don't realize that since SD800 till 805 it's been mostly just Adreno tweak ups to push for this QHD insanity not about proper ARMv7 to 8 gen transition.

For perspective Intel bled to a tune of 4bill to get their mobile SoC to its current performance : power draw parity that's gotta still hurt. And they're Ineffingtel ffs.

It's curious that Qualcomm, the world's 3rd largest chip maker (and largest fab - less chip maker) is so dependent on business from Samsung, the worldworld's second largest chip maker (higher volume but lower income than Intel). You might think they would notice the danger in that. Qualcomm has had better 4G support than Samsung in the chips, but that's certainly a fixable thing. Particularly as 3G support became universal, and the emphasis moves to LTE.

44. Suo.Eno (Posts: 475; Member since: 17 Feb 2013)


Not that curious. Obviously they gotta depend on proper device makers for their wares so which other bigger customer than Samsung really. And everyone knows the prob with Samsung is that they can't really stop everything else they're doing and go Exynos all in back with Exynos 4 and 5 because they're also an ODM themselves namely for Apple and yes were ill equipped with lacking radios. Fastest stopgap way to appease NA carriers = pay for Snapdragons, build Galaxies with it and ship those out.

Unlike all the "boys" on here, I actually spend lots of money on my cell phone hobby. Anyways I have both versions of the Note 4 and the S805 version is better in every way. Battery life especially. Web browsing heavy script page's, the Exynos has always had issue's with fluidity. My TAB S with the Exynos same thing.

So you are experiencing the same thing? I am also experiencing that exynos version is more battery hungry than sd805. May be due to the radios as stated by some users. But I will disagree with you about fluidity, both are equally fast. I didnt feel any difference in performance yet. Infact the sound quality of exynos is better than sd805

I thought that this heat problem was just a rumor. If it is true, so LG is just limiting the SoC power, what is the only solution they have, if they do not want to delay the device launch.

In this scenario, we can understand Samsung uses just the Exynos.

btw, i want to ask, which is better?
14 nm Exynos 7420 at 1.3/1.9 GHz or 20 nm S810 at 1.5/2.0 GHz, in terms of performance ?

posted on 25 Jan 2015, 12:20

59. wargreymon (Posts: 669; Member since: 05 Nov 2013)


Looking at pure clocks the Exynos would be performing less. But the lesser node would make it use less power and generate lesser heat, unless its badly optimized. Same goes for SD810, like the rumors says it can be badly optimized and be throttling a lot. But there are some very decent Geekbench 3 results from preproduction G Flex 2, so I´ll just wait for the end results before I pick up the pitchfork.

On a funny note, imagine the manhunt Qualcomm would go on if these rumors are just for defamation, they seriously got some bad PR over this.
