Thanks to Samsung's new models, heat-pipes might become popular in smartphones

Samsung apparently wasn't convinced that the Snapdragon 820 chipset wouldn't overheat like its predecessor, the Snapdragon 810 chipset. After all, it was Samsung that practically led manufacturers to avoid the Snapdragon 810 SoC whenever possible last year. For Samsung, this led the company to employ their own Exynos 7420 chipset on all of its high end models, even in regions like the U.S. where traditionally a Snapdragon solution was used...

Yes, it's Exynos in India. This is what Anandtech had mentioned about 820-powered Mi5: "On the GPU side we see some good improvements as well, although it seems the Snapdragon 820’s GPU is yet again oversized for smartphone form-factors as power figures are well above sustainable thermal envelope of phones such as the Mi5, so significant long-term throttling should be expected."

That doesn't seem so encouraging.. Heating can be real annoying as well as wastage of energy.. I know it first hand because I own a Galaxy s4 i9500 Exynos octa which is renowned for being a portable heater. The heat sometimes is so much so that it worries me to use the phone further.

Hmm now I am curious about how S7 with all those heat pipes are gonna perform.

Samsung? I thought it was Qualcom that should get the credit.

for making heating issues?

psh after nvidia 7950GX2, no heating issue scares me, that thing was a radiator, it could heat up a room quite effectively if you just gamed with moderate stuff back then.

PhoneArena- Is it official that only the S7/S7 Edge models powered by SD820 uses the heat pipes and not the ones with Exynos Octa? I find it hard to believe. Because I thought, since these phones are majorly touted as pro gaming & VR enabled sets Samsung went a little ahead to make sure the heat generation prolonged use(esp with those larger batteries) is taken care of. Isn't it bad to put just one chip in suspicion based on old rumors. Since Samsung made the disclosure of the new heat pipe in their presentation, I think the design is applicable to all S7/S7 Edge models irrespective of the SOC.

exynos version also has a heat pipe.

Wish my A9 overheated so I could have a cool heat pipe

be grateful that it performs very well without throttling.

Heat-pipe is a terrible design decision. I can already see S7 overheating LOL. A9 is an amazing SoC and Apple isn't idiot like Samsung to put a heat-pipe in a passively cooled smartphone.

Leading the heat away with one of the most effective ways to do that is a terrible design choice? how? that is exactly what they are designed for so the phone doesn't overheat? it uses a larger surface to cool down with leading to overall lover temperatures?

Heat pipes are a terrible design decision? Really? So why do PCs even with active cooling have them? Why do consumer and professional grade GPU's have them? The concept of the pipe is to draw the heat away from the chip in the event it gets to hot. Considering what 90% of the peopel int he world use their phoen for which is texting, music and video and basic games, the solution will likely never even be used Also, since Samsung phones by default how power save mode active, the chances of this happening to most users is 0%. Its only the wanna be gamer who think their phone is a video game machine is the ones who will have trouble. Recording 4K for long period above 5 mins could drive the CPU up. However, with a pipe that could mean being able to simply record a longer video. if you think its a terrible solution, which we have used in computers for longer than you've been alive, then why don't you put on yoru engineer cap and come up with a multi-million dollar better solution and sell it to the OEM vs sitting her and trying to be all smart by complainign about it. Don't like the solution, don't buy the phone. I didnt even see any huge problems with most users who had a device with the S810. Sure lots of people had issues, the majority didn't. As iPhone users typically say, if the problem isnt widespread, then it really isn't a problem. Its more of an annoyance for people who actually had the problem which was like how many? We have no idea how the phone will perform. To me the 820 is just the 810 with a new name. Qualcomm chips offer better performance. Chips get hot only under very heavy load. Most peopel will NEVER drive a phoen to that amount of load, so what exactly is the point. Even if they do, Samsung provided a solution that must work. After all, unlike Apple; Samsung actually rigorously test their phones. How many Samsung phones have been released with out the box terrible experience where it has a huge amount of issues? NONE. Can Apple say this? NO! Samsung phones do have problems and unlike Apple, they have never denied one. They have always stated when aware, that they are aware and are working a solution. This solution must work. We will find out in tests...right? So how about we dont pass any judgment without confirmation that there actually is an issue.

Stop being a fanboy. Samsung phones have had issues out of the box before and you know it. Just cause you love samsung like they are your gf and hate anything Apple doesn't mean you should lie thru ur teeth. What about the S3 issues with cracks around the camera on the blue model, or I think it was the S4 with camera issues right after release. Anyone that comes here enough knows that your nothing more than a troll that claims samsung does no wrong and are totally perfect. You claim your not a fanboy of any company but your comments say very much otherwise. They are just phones, get a life.

Z5p did a great job taming the dragon. Not only did it tame the dragon z5p had the best performance of a sd810 device.

the Z5p was also the last device to get the SD810, so obviously they had to do something about it?

Heatpipe is not a good thing under a passively cooled body. It spreads the heat inside your phone, making processor run at max clock speed for extended periods, making your phone heat up more. It's just a marketing gimmick, nothing more. Nothing can destroy heat, it's a form of energy. If you believe that heat-pipes keep your phone cool, either you've never done science in high-school or you're just dumb.

Heatpipes will not cool your smartphone of course, as you said. But they would spread the heat generated by the SoC better around the glass back and metal edges, reducing the amount of hot spots (still hot tho), because AFAIK glass is more insulating of heat when compared to metal. A larger surface area to dissipate the heat would lead to a more even heat transfer, not by much, but pretty decent nonetheless.

29. TyrionLannister unregistered

Yeah, but that would still allow the SoC for sustaining the clock speed for longer, instead of throttling down, which will generate more heat compared to no heatsink. Also the whole phone will become hot. You are forgetting that in the case of heat pipe, more heat will be generated in comparison to no heat pipe as processor doesn't throttle down. So even if it spreads out, the phone will be still as hot, and it will be hot over a larger area, not just one spot. So a heatsink makes your phone hotter, not colder. Yes, it increases performance but at the cost of more heat and battery drain. The fact that S7 needs a heat-sink tells us that the processor is crap. If it was as good as A9, it wouldn't have needed it.

"The fact that S7 needs a heat-sink tells us that the processor is crap." By that logic the A9 would crap (but it's not, far from it actually) The iPhone has a full metal body, which likely can dissipate even more heat that a glass back and thin heat pipe

36. TyrionLannister unregistered

The metal body is not made specifically to dissipate heat. It's for design and durability. Quote me on this, but I think SD 820 is gonna heat up pretty badly. Also, anandtech found the same as S7 and G5 units they had heated up a lot.

You are comparing a 1.6ghz vs 2.3ghz Cpu. IOs is vs Android. IOs does not require that much Cpu processing like Androids. You are dissing a powerful soc vs a standard soc. Why would you compare iOS to Android? Big difference.

48. TyrionLannister unregistered

Just stop saying stuff which you don't understand. You're just embarrassing yourself. Comparing twister with kryo clock-per-clock shows how little you know.

And do explain? IOs is a dumbass unix OS. Android Linux is running on java, so obviously it will need more Cpu power. And Art is still heavier than iOs. If anyone can try to use Exynos socs on iOS it would be what?

57. TyrionLannister unregistered

Exynos will still be slower than A9, no matter what OS it runs on.

Lmfao ip6s+ at 1.8ghz A57 cores vs A53 at 2.1ghz Exynos.. Yea really. Wtf
