Exynos 8890 DRAM Bandwidth

I'm interesting is asking if someone may run the below DRAM bandwidth app in "Misc" mode using 2 & 4 threads:

Search for "RgBandwidth" in the PlayStore.

As you may all know the new Exynos 8890 has in it the internally developed ARM CPU cluster (the BIG cluster) called Exynos M1.

According to Andrei's below detailed article we should see a major leap in raw DRAM bandwidth due to a completely redesigned Cache Coherency mechanism:

"Samsung Announces Exynos 8890 with Cat.12/13 Modem and Custom CPU" - November 12, 2015 - from anandtech[dot]com

I don't own (yet) this phone, but I would be glad if someone could run this benchmark with both the S6 & S7 to see the difference.

Thanks

Pierdamiano

memory so far is enough. some stock bloatware occupied some memory tho.
[Samsung Galaxy S7 Real Life Review] DSF:
Unfortunately they didn't fix the issue. If you start to use an app more (eg: facebook, youtube), the system removes other recently apps from memory. And this happens with battery saver disabled!

With built-in app battery saver, the system remove apps from RAM after few minutes/hours of no usage. Eg, if you leave your apps overnight, the next morning, most of the apps will reload. This happens only with battery saver on.
[Samsung Galaxy S7 Real Life Review] hulkamaphone:
always seem to have lots of ram free, moreso than my other device the Xiaomi Mi5.
[Samsung Galaxy S7 Real Life Review] Geeks Empire:
it about 3 yrs I don't use Samsung galaxy as daily phone for long time!

I remember famous gui problem called S-Lag on galaxies and also lots of news about new and clean gui

also I experience it but not for long time!

how RAM usage and freeing process works? without rebooting for like 10 days of heavy usage. (last long time experience with galaxy was not good ;) )

but really like to buy upcoming S8... so need to know more
[Samsung Galaxy S7 Real Life Review] TheMadScientist:
since the 5.1 update android has done so well on managing ram almost on all devices but i give it to previous poster about s lag

sammy im so proud of you and what youve almost become.

ram managment has improved so much more in the mm updates i cant wait to try nougat

damn shame between ram and core pros power it beats my pc into the ground
[Samsung Galaxy S7 Real Life Review] brownd7380:
I have a 4gb ram honor 8 and it does out perform the s7, I own both in real world speed and battery life.
[Samsung Galaxy S7 Real Life Review] Cyn1:
4GB is more than enough.
[Samsung Galaxy S7 Real Life Review] DSF:
I hope this is a (bad) joke.
[Samsung Galaxy S7 Real Life Review] alantlwu:
9/10, mostly satisfied, but some apps get refreshed all the time.
[Samsung Galaxy S7 Real Life Review] michel333alfa:
7.0

Really good multitasking

Mine does not free up memory while busy or asleep at night)
[Samsung Galaxy S7 Real Life Review] carlocristi:
S8 8.0 oreo exynos

The multitasking seems great, it's uncomparable with the last years flag ships. Samsung started doing good optimizations to multitasking and now they are at almost the same level with HTC. Thumbs up!

Some phones exhibit choppy scrolling, especially when navigating long web pages when multiple apps are running in the background. Rate this thread to express how you smooth scrolling feels on the Samsung Galaxy S7 under such conditions. A higher rating indicates that scrolling is always buttery smooth, even when you're reading a 10,000 word article on "how to kiss a girl".

Then, drop a comment if you have anything to add!
[Samsung Galaxy S7 Real Life Review] mrnamster:
What's with the choppy scrolling? Do I have a defective device?
[Samsung Galaxy S7 Real Life Review] jarayn:
Silky smooth so far.

What have you found that isn't smooth?
[Samsung Galaxy S7 Real Life Review] kochoid:
Chrome scrolls facebook well and considerably slower than the S6. Fenix scrolls twitter well, but slightly less smooth than the s6, but not so much to have me find another twitter agent.

Settings menu scrolls perfectly.

Notification shade drops down with not dropped frames, which is a major win.
[Samsung Galaxy S7 Real Life Review] mrnamster:
Happens a lot in Chrome and Tinder. Also stutters here and there during general use.
[Samsung Galaxy S7 Real Life Review] jarayn:
Not a bit on chrome. Or notification pull down. Those are really smooth.

Mines exynos BTW.
[Samsung Galaxy S7 Real Life Review] THORMUNZ:
So far butter!
[Samsung Galaxy S7 Real Life Review] combatmedic870:
Flicking up and down through is smooth. But, scrolling slow with my finger is choppy. Even here on xda.
[Samsung Galaxy S7 Real Life Review] Aikon94:
Really slow scrolling! I don't know If mine is defective..
[Samsung Galaxy S7 Real Life Review] JAYNO20:
How choppy are we talking? I personally came to XDA on my phone just to see if I could reproduce it and my phone seems to be silky smooth no matter where I'm scrolling. Any chance for a video of it?
[Samsung Galaxy S7 Real Life Review] Steffe89:
I have seen shutters, but that's because I'd the ads. Using an as blocker and it's pretty smooth
[Samsung Galaxy S7 Real Life Review] mikev190:
I've found chrome to be choppy both on the s6 edge and the s7.

I use the Samsung browser and it's spot on :)
[Samsung Galaxy S7 Real Life Review] mrnamster:
Swapped my S7 and it's still choppy, but it seems to be dependent on the app and not the device.
[Samsung Galaxy S7 Real Life Review] insomnia:
smoother than BUTTER here on Exynos version. cannot make it lag even if i try.
[Samsung Galaxy S7 Real Life Review] dspain28:
I was having this problem too, extremely choppy scrolling on almost any web page, I read some forums about a similar issue with the s6 and it recommend toggling the JavaScript support in both browsers and after doing so its pretty smooth, buttery smooth with JavaScript off but we need that on in 2016
[Samsung Galaxy S7 Real Life Review] benbailey84:
Honestly, so far the S7 is a lot smoother than the S6 too me. This thing is buttery smooth so far. Samsung just needs to ditch their processors and stick with snapdragon. I can't get over how much smoother and responsive this phone is compared to the S6.
[Samsung Galaxy S7 Real Life Review] s3icc0:
sometimes I feel there is some space for improvement ... egg app list is not butter fluent
[Samsung Galaxy S7 Real Life Review] MirceaForce:
new update is available for french version :) 70MB
[Samsung Galaxy S7 Real Life Review] DankNuts:
Snapdragon version, tested out on 5GHz WiFi.

Mine is smooth in chrome, but chops when a page is loading or the page has heavy content/lots of pictures when scrolling faster.

Browsing XDA in Chrome is overall smooth, but can be choppy when the page is finishing loading and especially scrolling faster with longer posts with lots of ads between the posts.

Instagram and Twitter are overall smooth, but again if pictures are loading it gets choppy when scrolling faster.

Overall nice and smooth, for me seems to be just faster scrolling that causes choppiness.

Seems pretty normal to me, very happy with the S7 so far.
[Samsung Galaxy S7 Real Life Review] JAYNO20:
What website specifically? I have yet to see any choppy scrolling on this device.
[Samsung Galaxy S7 Real Life Review] XDA_RealLifeReview:
Some phones are great to take camping because if you play Asphalt 8 long enough, the back warms up to the ideal temperature that can bake bread. Rate this thread to express the extent to which the Samsung Galaxy S7 stays cool under extended heavy use. A higher rating indicates that even when playing strenuous games for long periods of time, the phone doesn't get uncomfortably warm.

Then, drop a comment if you have anything to add!
[Samsung Galaxy S7 Real Life Review] Lastwurdz:
what i find is that my device (S7) stays very cool under conditions that my other device (m8) would overheat. now i dont play traditional games on my smartphone but i do run chess engines against each other on all 4 cores and typically after about 10 minutes i would have to stop because my m8 would reach over 50 degrees Celsius (122 Fahrenheit). under more strenuous conditions the s7 only reached 40 degrees Celsius (104 Fahrenheit) after running for close to an hour. although the phone got physically hot which may be alarming, but i relied on an app to measure the internal temp. once i get a case for the s7 i probably wont even notice.

all in all, these results blew me away. i will try this again after i root the s7 and overclock it. but for now im very impressed.
[Samsung Galaxy S7 Real Life Review] jonahtriangle:
The question here is does it throttle and how fast does it start throttling? A lot of people are complaining about the heat but really it should be hotter. The new heat pipe is supposed to disperse the heat to the frame away from the processor. Now if it is only hot where the processor is located like my s6 then that is a problem.
[Samsung Galaxy S7 Real Life Review] ThoreauAZ:
I've been pleasantly surprised with how cool the device stays as well. I keep it in an Incipio DualPro (although I find myself taking it out often either for Gear VR time, or just because the damn phone is nice to look at) and tend to go on usage binges frequently. Even throwing in a little gaming here and there (mostly Clash of Clans which used to warm up the S5 pretty easily.) So far, so cool. Even wireless charging (slow or fast) seems to run cooler.

If it's throttling to keep the temperature averages lower, then it hasn't been of detrimental effect to my own usage patterns so far.
[Samsung Galaxy S7 Real Life Review] mayurkawale:
I am actually hater of Android phones, but the features provided by Samsung Galaxy S7 and edge S7 are truly amazing. actully I personally saw after charging all Android devices they get heated. But I must say this S7 and S7 Edge are not from this family. Also there are some great features like water residence technique.... etc.
[Samsung Galaxy S7 Real Life Review] xSkyFlasherx:
does it get hot when constantly using the facebook app(Like my S6 overheats sometime when using it often due to heavy usage)? i'm buying the S7 next week
[Samsung Galaxy S7 Real Life Review] whoamanwtf:
After a few days of use I can say that it does not even get warm much less hot while doing anything I normally do, including gaming and I play a wide range of games on my phone including some pretty graphical ones. The only time it has felt warm at all was when I was first downloading and trying all of my VR games, not sure why though because I played a couple hours of VR last night and it did not heat up at all, maybe it was burning in?
[Samsung Galaxy S7 Real Life Review] nappent:
Both my S7 and my wife's S7 get very warm. I immediately noticed it on the first boot for both devices when the Play Store was installing all of our apps. Installing about 50 apps took over a hour. I think both of our devices are defective as they are not consistently running smoothly as well the LTE speeds are 50% slower than our previous S6 and S6 Edge. So far a factory reset has not corrected the problem for either device. That said both S7's still score very high with Antutu 128000-129000. It's all very odd.
[Samsung Galaxy S7 Real Life Review] mcbutters:
I switched from the M8 to the S7 and my M8 never got this hot. My S7 is always getting warm and the battery life sucks. I got it 3 days ago and have yet to play a game or watch media on it and it still heats up and the battery is down in the teen % by late afternoon.
[Samsung Galaxy S7 Real Life Review] insomnia:
Qualcomm SD820 sucks unfortunately. Gets hot, bad battery life, ****ty DAC.
[Samsung Galaxy S7 Real Life Review] konoplya:
a bit off topic.. how is that incipio case working out for you. i've been eyeing it but haven't read any feedback. is it a slick case or does it have some texture for the grip? rubbery or plastic? thanks for any help.
[Samsung Galaxy S7 Real Life Review] ThoreauAZ:
I had the same model case for my S5 and loved it. It was bulky but was the kind of added protection I was looking for when i was out hiking or backpacking.

The version for the S7 (S7 Edge, specifically) feels more streamlined to me. Definiteky thinner materials, and because it has to keep the two long sides of the phone fairly clear due to the edge screen, it's a good bit more flexible (i can pop the phone in and out without having to first separate the two case layers.) I'd expect the non edge version for the s7 may be more in line with what I remember from my S5 days.

That said, the grip/texture is a nice balance between slick and grippy. It has a rubbery feel, but it doesn't snag on its way in and out of a pocket. Its just enough to know that it won't slip outta the hand.

Meanwhile, on the heat subject again, the s7e managed to reboot itself during a VR session and when it came back up, it seemed to have forgotten a lotta settings. Edge panels were no longer selected, double tap home yo launch camera went away, and probably 8 or so others that I noticed eventually. Easy enough to set them back, but thats the first time ive ever seen something like that on an android device. I can't say for certain that it was heat related, as it couldve rebooted due to any number of unfound software bugs, but it certainly had become fairly toasty during that session.
[Samsung Galaxy S7 Real Life Review] konoplya:
so in other words you'd recommend this case? thanks for the info btw. very helpful.
[Samsung Galaxy S7 Real Life Review] jonahtriangle:
No problems with heat or battery here. Way cooler than my s6.
[Samsung Galaxy S7 Real Life Review] MirceaForce:
+1
[Samsung Galaxy S7 Real Life Review] JAYNO20:
Definitely cooler than my s6 and to the person stating this phone gets hotter than his m8 did, you DEFINITELY must have a bad phone. The m8 and m9 always got very hot in my experience this phone is almost like ICE in comparison. My s6 even was cooler than either of those 2 and the s7 is even cooler than the s6. Battery life seems to be a little better than my s6 as well.
[Samsung Galaxy S7 Real Life Review] impmanpdx:
Pretty rough

I switched from my old S4 to the S7 on day one, and equipped it with all of the same accessories. I work in a kitchen, and it's often extremely hot on the line, but even in an Otter Defender my S4 would rock all day as a bluetooth music player connected to our soundbar. Ever since the switch I will get between 30-45 minutes only running DoubleTwist on BT before I get a hard reset from overheating. I've taken to leaving it in the pantry, but now I have to run off the line every time I want to change the song or the volume. As a desktop builder I understand the compromises between heat, performance, and cooling, but this seems a little sensitive.
[Samsung Galaxy S7 Real Life Review] Strazzi:
I have g935f. Before that i had G920f and i have to say, best phone i ever had in my hands. No heating... Playing games for a few houers and no throtel no overheatin. Batthery is much bether than on S6, but i think that MM for S6 is more optimized for S6 then S7. Abouth heat, i think that the diference is in CPU. Exynus VS Snapdragon...
[Samsung Galaxy S7 Real Life Review] thafz:
Can I just ask you. What's the average temperature your device sits at when using it? And the maximum you've gotten it up to. I need to compare mine to it as I came from a s5 which didn't really get hot. But because the s7 is new I'm also quite paranoid with the heat and need to see if I have a defected device or not. And please state wether you have exynos or sd

---------- Post added at 07:18 PM ---------- Previous post was at 07:14 PM ----------

Do you have exynos or snapdragon? I've got exynos and I experienced a average of 33 degrees Celsius, is that normal or average
[Samsung Galaxy S7 Real Life Review] JAYNO20:
I don't have any temperature measuring programs on the phone, but it rarely even feels warm. It will show heat a little more than your s5 does because its glass and metal but the s7 runs cooler than my s6 and the s6 wasn't really a hot phone either IMO.
[Samsung Galaxy S7 Real Life Review] s3icc0:
haven't had a chance to see it overheating ... not playing aaa games
[Samsung Galaxy S7 Real Life Review] nosrace:
Normal that my s7 heats up to 50 celsius while surfing? Im on exynos
[Samsung Galaxy S7 Real Life Review] mehtamitul:
Mine goes only to 33°C. While gaming it goes to 37°C. I am also on Exynos. It's Made in India with latest March update preinstalled.
[Samsung Galaxy S7 Real Life Review] RisinT96:
Coming from an S3, my S7 (exynos, not edge) gets pretty hot even at standard use like some web surfing in chrome or whatsapp chatting.

And the battery seems to drain for no reason :( , but damn is it fast as hell.
[Samsung Galaxy S7 Real Life Review] darkinners:
Gets really warm with little use.

At initial setup while syncing my iOS data to S7, device felt warm to touch..

Also for no reason when i applied Material design black theme, the device was warm to touch when it was idle.. Removed it and everything came normal..

Noticed that when device is charged in switched off state, its quite warm to touch. but when charged with device turned ON, can feel slight warm..
[Samsung Galaxy S7 Real Life Review] Howlbeck:
Only time it really gets hot is when I use the Navigon app with realtime traffic enabled, regardless if plugged to the standard car charger or without - otherwise I can't complain, not doing excessive gaming though. Btw couldn't resist and rooted a few days ago, got rid of all the Knox stuff (I hope) and not looking back so far. Have to say this was the 1st phone with root already available which stayed stock for 2 weeks.
[Samsung Galaxy S7 Real Life Review] MetalSaint:
I disabled fast charging feature.. now its fine try it?
[Samsung Galaxy S7 Real Life Review] Howlbeck:
It seems that did the trick, thx :)
[Samsung Galaxy S7 Real Life Review] GalaxyGusta:
only when fast charging it gets warm EXYNOS
[Samsung Galaxy S7 Real Life Review] *Detection*:
Gets warm fast charging, to be expected, but gets very hot viewing cameras for my CCTV with the CCTV app, like 5 minutes viewing and the phone is red hot

Think that's the apps fault though, drains batteries like nothing else, on the S5 too
[Samsung Galaxy S7 Real Life Review] esseven:
Little bit disappointed with the heat produced by my snapdragon 820 powered Galaxy S7.

When browsing the internet (on 4G, not wifi), the temperature goes about 33 to 35 degree C in average, and it feels really warm on the metal bezel (this is my first metal-bezelled phone though), and very uncomfortable when making / taking a call after browsing. The idle temperature is quite ok (27-30 degree C), although still higher than the exynos 8890.

Because I read that exynos runs really cool compared to snapdragon, I am not surprised, but I don't expect it to be so hot either. Battery life is noticeably worse too, about 5 to 10% compared to exynos (those 2 issues are enough to get rid of raw processing power advantage and the superior GPU of SD820 and its Adreno 530).

Is it normal for a snapdragon 820 Galaxy S7?
[Samsung Galaxy S7 Real Life Review] KingRaheel:
my phone heats up pretty fast when you use it...not playing games...normal usage...gonna try a kernel today
[Samsung Galaxy S7 Real Life Review] Travis Bickle:
What temperatures does the battery reaches?
[Samsung Galaxy S7 Real Life Review] AB__CD:
Galaxy S7 thermal throttling is definitely present (can't match 801), but also not any more than what you should be concerned about. Exynos dual SIM, device was charging through PC USB, in air-conditioned room. Two simultaneous GB4 runs. I imagine blue line is BIG cores, gray is LITTLE cores.
[Samsung Galaxy S7 Real Life Review] KingRaheel:
60 degrees...there were times when it was 65 and the phone turned off automatically
[Samsung Galaxy S7 Real Life Review] Travis Bickle:
60 degrees the battery??? What app did you use to measure it? And you sure it was the temperature of the battery and not some other sensor?
[Samsung Galaxy S7 Real Life Review] KingRaheel:
Well I had apparently used kernel auditor for measuring it which showed me 60 degrees battery temp .later when I used SetCPU it was locked at 45 degrees..didn't increase above that but CPU temp was around 60 degrees...I guess that's normal, isn't it?
[Samsung Galaxy S7 Real Life Review] Travis Bickle:
Doesn't seems right, you should download" GSam battery monitor" and keep an eye on the battery temperature. It also has a diagram that shows the temperature during the day. What I've noticed is that battery's temperature is almost the same as CPU's.
[Samsung Galaxy S7 Real Life Review] jioleight:
i have no problem whatsoever. it only heats a lil bit when fast charging. playing hardcore games do not make it hotter than when fast charging. definitely better than when i was using s4. S7 Exynos here

UPDATE:

apps that run on background that eat huge chunks of the memory and cpu is the culprit for overheating issue for me. like facebook messenger. ill try to see if save power feature in the nougat version will kill the app when not used.
[Samsung Galaxy S7 Real Life Review] *Detection*:
Left mine on a tripod at about 11am in the sun doing a timelapse, came back to get it at 12pm and it was absolutely red hot from the sun

Brought it inside and put a fan on it for a while until it cooled off

Hopefully didn't damage the battery, it was almost too hot to touch
[Samsung Galaxy S7 Real Life Review] Makebetterlife:
just a bit hot randomly
[Samsung Galaxy S7 Real Life Review] esjames:
My wifes phone has been having some serious overheating issues lately (not related to oculus) to the point that she can't hold it in her hand. She doesn't do any gaming cept' words with friends, and she uses facebook, instagram primarily with texting. Weird thing is I do heavy gaming on mine to stress it and it stays cool. I tried a factory reset, re-flashed firmware with odin with all the same results. Now she is worried her phone is going to spontaneously combust like the note 7.
[Samsung Galaxy S7 Real Life Review] *Detection*:
Does it cool down when it's switched off?

If not, get the battery checked, but if you have factory reset, and it's still doing it with no other apps installed, get it checked anyway
[Samsung Galaxy S7 Real Life Review] takerhbk:
No heat even while charging. Don't know why some people are complaining.
[Samsung Galaxy S7 Real Life Review] concoc:
I think most heat issues come from quick charge feature. I have disabled quick charge and s7 is the coolest smartphone I have ever found.
[Samsung Galaxy S7 Real Life Review] iBolski:
I will say, if I play a game, such as The Walking Dead: No Man's Land, for awhile, it can get quit hot. I have it in a case, so it's not too bad, but I have had it out of the case before and felt it was getting hot. Not so hot that I couldn't hold onto it.

Also, when charging with fast charge, it gets hot. No fast charge, it's fine.

However, once I stop playing the game or unhook it from fast charging, within a minute or two, it's cool to the touch again.

Best smart phone I've had yet.
[Samsung Galaxy S7 Real Life Review] Cyn1:
Can get quite hot, but not dramatic.
[Samsung Galaxy S7 Real Life Review] michel333alfa:
Mine gets hot at the normal usage, without battery saving mode. Not so hot that I can't touch it, but it does not feel good. I hope it will not blow up.

My samsang galaxy S 7 also heat while operating normal task...also battery charging rate 1hrs from 5%to 100% but drain time in 1hrs near about 50%...is my phone working right or overloaded
[Samsung Galaxy S7 Real Life Review] IDPBBrisa:
I can reach 70ºC (aprox~156ºF?) easily while gaming(mostly Summoners War) and screen mirroring (and controlling) to computer.

I have even lowered both resolution and textures through game tuner, to about 50% each.

My flat S7 (exynos) reach about 40ºC-50ºC while doing normal stuffs. I do live in a tropical country.

But, if i game without screen mirroring, my phone drops down to 50ºC-60ºC.
