It's not that Snapdragon 810 overheats, Galaxy S6 might just be unleashing a chipset war with Qualcomm
The use of Samsung's own Exynos line of chipsets instead of Snapdragon 810 in the Galaxy S6 might not be because of the purported overheating issues the TSMC foundry allegedly has with Qualcomm's newest retail SoC, but because Samsung actually wants to go to war with the world's most famous mobile chip maker, and take it head on with its superior 14nm manufacturing process.

Exynos 7420 and Snapdragon 810 - these two chipsets are already going into flagship phones, says Korean media, citing industry sources, but Samsung is placing the Exynos in the Galaxy S6, while Qualcomm makes do with the LG G Flex 2, and the Xiaomi Mi Note for now. After mishaps with overheating Exynos 5 series, Samsung used its homebrew processor line sparingly, but is now back in full force with the Exynos 7420, that is about to go into the S6.

Regarding the differences between Snapdragon 810 and the Exynos 7-series, we'd have to wait and see exactly what modification Samsung will use for the S6, but one thing is for certain - it will be built on the superior 14nm process, whereas Qualcomm uses 20nm for the 810, and only this year will move down to 14nm. In general this means less power consumption plus smaller processor footprint and/or superior performance at comparable clock speeds, but Qualcomm has other aces up its Snapdragon chipset sleeve.

One of the advantages used to be its excellent multiband LTE modems that it paired with the Snapdragon SoCs, but now that Samsung created an LTE Cat. 9 radio of its own, that point becomes somewhat moot - more so it will be built on 20nm, whereas Qualcomm's LTE radio is still at 28nm. Granted, there won't be support for as many bands as Qualcomm does now, but that would worry only heavy globetrotters.

As for the Snapdragon 810 optimization for 4K encoding, decoding and streaming - it remains to be seen how Exynos will fare with those, though we wouldn't worry too much about it, as Samsung's chips have proven capable enough so far, and, face it, how many 4K streaming services are out there at this very moment to take full advantage of.

Samsung is desperate to increase it's revenue. When Qualcomm have a processor build on 14nm they're going to destroy Exynos 7420.

You know that qualcomm doesn't manufacture fabs do you??

Qualcomm will need samsung to make their 14 nm SoCs. As TSMC is going with 16 nm.

why do you defend Qualcomm so strongly? The only thing you can do with this much power these days is play games, the phones are already more than fast enough to do most smartphone tasks. And Qualcomm , has done nothing to help us with video games. NVIDIA has, hell even Samsung has done more, so what has Qualcomm done? Nothing! Qualcomm needs its ass kicked, then perhaps they'll do more for us as Nvidia and Samsung have.

when Qualcomm build first 14nm(snapdragon 820), samsung will have one step ahead with newer Exynos 7430... also recently leak reveal 820 will be made using 14nm samsung technplogy... how about that?

When Qualcomm will have a new 14 Nm SoC Samsung wil also have a much better chip than Exynos 7420 that's why your post is nonsense.

You're ridiculous. QC has already stated that the 820 won't be available until Q4. Considering their track record, it won't be available until 2016. Did it ever occur to you that there will be a better Exynos available at that time? No, because you're clearly shortsighted.

See now, I have to ask, have you ever owned or directly compared same generation products yourself?

I have, and honestly, there is very little difference between devices released at approximately the same time (within around 3 months), sure benchmarks might say 'this' or 'that' is better, but in actuality there is no real difference.

I'd recommend instead of looking at the individual components, look at the whole product and chose the one that suits you best.

There's not a ton of innovation here. The die size shrink is as close as you get to that, and even that has already been done. Exynos 7420 and SD810 are both stock ARM A53/A57, so the design work was already done for both companies by ARMH. Only Nvidia and Apple are currently building custom silicon that's worth a damn.

Apple doesn't design their chips for bleeding edge speed, so it is doubtful they ever top the benchmarks. What they do is make one of the fastest chips that does everything well. That's the point of custom silicon. They have been designing chips for a few years now, and the folks who know SoCs say that nobody else is close to having such an advanced design. There's a reason there are a bunch of threads on XDA for turning off encryption on the Nexus 6, whereas nobody even notices it on the iPhone 6/6+, and why the Nexus 6 has average battery life compared to the iPhone 6+, even though the N6 has a bigger battery.

Not really... When did you think Samsung got their own Exynos game? Certainly not this week this year lol. It's only natural. If they got the muscle to do it then why not.

Also the headline are tad overblown. This will only become a Samsung vs. Qualcomm war after Samsung announce that Exynos will be readily available for other OEMs but to get there they'll need the production capacity that they don't have (or maybe they do) yet. Remember that the 1st time they mixed their SoC bag for Galaxies was not only about radio probs for diff regions but also because they can't rapidly put out Exynos across modeld in that short space of time.

Not exactly black and white... e.g Apple could have just stuck with A7 which imo still a very capable piece of work that can withstand w/e that comes next actually but probably a tad s**ttier TDP than A8 now, slap another 1GB RAM in that and called that a day no? Obviously they can't and they'd run out of things to say even before the per annum presentation gets halfway. And iPhone's total demographic are the same as anyone else's.... geeks and nerds come in at best 10% tops so why they went on and did it still?

The krait core is better then the A15. The Krauthammer is slightly weaker but but better in the battery to power ratio and in mobile that is the most important. You are an idiot

You offended very one by being so dumb. The reason why arm has the big.little configuration is because the A15 has horrible power consumption. That is a fact.

Nah. You call me dump despite being incompetent in the field of mobile sustems on a crystall. When switching cores in ASMP architecture CPU cores actually spend some time doing nothing which causes freezes and lags. Big.little architecture hasn't got this disadvantage that's why it is widely used now by almost every mobile SoC maker.

And not to mention about the fact that in HMP mode efficient "little" cores help the whole SoC to reach maximum performance per Watt => maximum performance before thermal throttling starts.

My prediction, is you're going to be annoyed all year by how things are going to pan out for Qualcomm..Even Intel has stumbled.
QC has mud on its face still, hasn't admitted they fell, so they won't wash mud off yet.
Only blind can't see that.

Seems out of place now that LG is considering suing over this Samsung created rumor.

Writing is on wall, word is out that QC fooked up this year an its either reduced performance or go with better soc, Grats Samsung.

I'm not a fan by Anny means, but I give Samsung a gold star for not kissing QC back end an pishing through with faulty wares.

There is no geekbench score for the M9. The only score for the S810 is from a reference device that have a 4k screen.

Funny how people feel so strongly about processors but forget whats importatnt are the softaware optimizations , APIs like metal mean iPhone will always run games better for the near future ,google hasnt figured out app development yet, processors can only take you so far

All the games come to iPhone first , android later.
for example infinity blade 1/2 or 3 with the famous unreal engine are still not available on android.
street fighter iv my favorite game on iO.S is not avaible as well

I prefer exynos over snapdragons for its audio capabilities and javascript performance.

14nm > 20nm given both chipsets are virtually the same. Both are stock ARM off-the-shelf 4x A53, 4x A57 configuration.

Qualcomm has a slight edge in GPU's, as if that matters. The only reason GPU's are even getting better right now is the needless resolution of new flagships. Game titles are laughably within the capabilities of all flagship GPU's at 1080P. Its a meaningless advantage. And trying to play this angle in marketing is going to fail miserably.

Samsung actually has an advantage with 14nm if their fabs can keep up with demand.

51. Somebody995 (Posts: 33; Member since: 28 Jan 2015)

I see a lot of misinformation and assumption in the comments here. Lets see if I can clear it out a bit....

First off, the Snapdragon 810 is a BONE STOCK ARM Cortex-A53/57 BIG.little design. This is basically the same as the Exynos that Samsung is using. The major thing to think about here, is why would Samsung use a competitor's SoC when they can make the same thing themselves? That is why Samsung is using Exynos.

Now some of you are going to argue that they could and have use Qualcomm SoC's in the past when they could make their own... the answer to that is NOT REALLY. Remember that in the past Qualcomm SoC's that Samsung used, you would find things like the Qualcomm Krait CPU cores. Not just reference Cortex-A9/15's. The Krait cores accomplish a lot more work per clock than Cortex-A9, and consume VASTLY less power than Cortex-A15, yet achieve the same "performance class" as Cortex-A15 (win some benchmarks, lose some..), but the point being that they achieve similar performance much more EFFICIENTLY.

But they aren't doing that with the Snapdragon 810! Fact is that Snapdragon 810 is a product that is rushed to market JUST TO SAY "SIXTY-FOUR BITZ NAOW!!!"

Like the Cortex-A15, the Cortex-A57 is really not a "phone" chip. It sucks more power and generates more heat than you want in a phone chip. This fact is something that *contributed* to the rumors that the SD810 was "overheating". In fact, the only issue is that it went into thermal THROTTLING sooner than they would like (i.e., sooner than a Krait). Thermal throttling does not mean overheating. ALL high performance phone chips (including Apple's) will go into thermal throttling when you run them hard for a long period of time. This is because you don't have the option of using an ACTIVE COOLING system (i.e., a FAN). The heat generated by the SoC will build up in the phone until it is forced to slow down **TO PREVENT** overheating.

With the NEXT round of Qualcomm 64bit SoC's, they go back to their own in-house designs, called Taipan. This is where the BIG.little design goes obsolete, because LIKE the Krait is sufficiently efficient that it doesn't need BIG.little arrangement (as Cortex-A7/A15 designs do...), the Taipan cores allow them to jam 8 FULL high performance cores into a single package without running into thermal or power consumption problems.

Now if you all will notice... Samsung is NOT known for developing their own custom core designs. They have exclusively used ARM reference designs. Since the SD810 does not HAVE that, they really don't benefit from using it over their own equivalent SoC's. When Qualcomm has the Taipan ready for market late this year, you can expect Samsung to go back to Snapdragon.
