[Q] A question about the GPU.

I know that the Note 3 got the Snapdragon 800 8974AA(GPU clocked at 450 MHz).
So i ran the latest GFXBench 3.0(Manhattan offscreen) and got a score of 11.1, which is even better than the scores the Snapdragon 800 8974AB(GPU clocked at 550/578MHz) got.
How can this be?

maybe its caused by throttling down due temperature

Maybe memory of Note 3 is faster and larger than other phone, which shouldn't be Samsung because S5 uses AC version. I think Note3 has very fast RAM and if other phone has slower (read cheaper) RAM it could bottleneck there. Also, as the other poster said the other phone could be thermally throttling, especially if the benchmarks were run multiple times to get average. You figure people running benchmarks would know better, but who knows.

The thing is that, other Note 3 get's around 9-10 FPS, which is normal for a 8974AA SoC. So either some Note 3's got the AB(which is unlikley) or Samsung is cheating again and overclocking the GPU to AB levels only for the Bench.

Samsung never overclocked anything, what they did in the past is ramp up frequency to maximum before benchmark started running, so there was no delay to get CPU/GPU to full speed, like you have with on demand governor. I don't believe it's cheating because you can set the governor to run full click yourself (if rooted) and benefit from this as well with any game/ benchmark. It also shows how inefficient ondemand governor is and maybe we should be using different governor setting which is interesting topic all by itself. I remember there was similar "scandal" few years ago in graphic card business, where drivers were optimized for particular benchmarks. Well, now all video drivers are optimized for specific, mostly graphic intensive games and we all benefit from it by having better performance, from lesser hardware. Maybe this could also benefit all of us by giving us better governors, so the phones can run faster with the same hardware, instead of being artificially slowed down with poor choice of governor settings. As far as other Notes running slower, thermal throttling due to multiple benchmark runs to get average would be my wild guess. Or maybe you deleted factory bloatware and change settings to make your phone faster, but no, you don't have AB version.

Exynos 8890 or SD820?

I will buy a galaxy s7 edge next week, but for now in stores only the exynos version is available in my country. Is it a good soc? Or should I wait more for the snapdragon phone?
On my note 3 the exynos chip was considered pretty bad, on both performance and battery life.

Exynos = Better CPU, Battery drain mostly from radio cell.
Snapdragon = Better GPU. Battery drain mostly from Android system (not sure is it fix able by update. )
If you're that person that love installing AOSP ROM. Snapdragon is your choice.

I will definetly root, most likely on day one, but I doubt I will be using AOSP roms.
Gaming on a phone isn't for me as well, I have my iPad or ps4 for that.
So the exynos runs better for day to day tasks?

For day to day tasks, there's no difference

For me I would prefer SD, cuz the ROM, kernel and mod development is much much better and I'm a flashaholic but in Europe only the exynos is available. And I'm scared there won't be so much to flash\development...
Am I right? How was the ROMs, kernels ect. on s6 edge exynos? Will devs come support us?

If your in Europe then it's not worth the hassle to get the snapdragon version IMO. That being said, the snapdragon has the better GPU, modem, higher single threaded performance, and more than likely a better ISP, DSP, etc and other blocks of the SOC. The exynos will have better multithreaded performance, just due to the fact that it has 8 cores vs the snapdragons 4, even though per core the snapdragons are faster. Like others have said developement will be noticeably less on the exynos. You will still get custom Roms but I wouldn't expect cm or aosp within a year, or ever. In dqy to day performance I would expect the snapdragons 4 very fast cores to be more responsive than the 4 slow cores and 4 fast cores of the exynos, especially considering most of the normal ui is processed on the slow cores and has to migrate to the fast cores when it needs it.

What is your basis for these arguments? Seems like most people in this thread are just making stuff up without quoting any real-world tests. Even Anandtech stated that the SoCs are pretty much equal (as far as they currently know, and they have already written pretty extensively about both SoCs), and that efficiency is what is going to set them apart. I wouldn't draw any conclusions without actually reading a comprehensive comparison of the two.

I just pulled the trigger on an Exynos version, despite living in the U.S.
Reasons you might consider the Exynos over the SD820:
1) LTE Bands, the Exynos version has far more LTE Bands for use around the world. If you travel around a bit, then it makes a bit of sense to have a phone that can receive data, regardless of the network you're on.
2) Battery drain: it looks like both SoC's are plagued with one thing or another that saps battery life, but the SD820 has an alarming amount of drain from the Android system. It still has great SoT (screen on time), but it's still a worry nonetheless.
3) Carrier lock: If you find yourself on one network, then this shouldn't be an issue. But within the past 2 years, I have been on a AT&T, then a business T-Mobile line, then Google Fi, and now on an AT&T business line. If the phone locks to a carrier, then you might have to wait longer or pay to get it unlocked.. which can be a drag.
That being said, I'm sure the development for the SD820 version will be immense. However, I'm coming from a Nexus 6P, and feel like the stock S7E ROM performs so well, that I won't need to root or anything. Android has reached a level of smoothness that was not found on earlier versions, especially in tandem with TouchWiz of old (older Notes and S phones were laggy, really). So stock ROM with the ability to use Android Pay/Samsung Pay will be nice.

I just pre ordered the UK S7 Edge, hoping it'll be Exynos.
In the benchmark thread people are getting virtually identical Antutu scores across chips. It looks like the Snapdragon is throttling earlier than the Exynos though, they always have ran hotter.

In singel core performance, the SD is a few % better. But in multi core, the exynos is about 20% ahead. So it does seem to run better with the CPU. Also it seems to run cooler, so throttling should be better.

We need someone to run consecutive 3dmark runs on the exynos in order to know whether the gpu throttles or not, and if so after how many runs. We already know neither will throttle the cpu in geekbench, but the SD820 throttles the gpu a bit after two 3dmark runs.

Yes we should await further testing. Since the SD is released in America for some already, the benchmarks for exynos are hard to find.

I'm pulling this from past experience with exynos 7420 kernel development, and every article ive read on the 820 and the exynos 8890, in addition to benchmarks on both and my own device. Qualcomm leads the world in modem technology. The one in the 820 supposedly has achieved parity with wifi. In addition we have the hexagon DSP and spectra ISP all of which can operate in a sort of HMP configuration to accelerate tasks. I would find it hard to believe that Samsung has caught up to qcom in these misc blocks of the SOC. But that's why I said most likely for that portion as I'm just making an educated guess. Single threaded performance is quantifiably higher on the snapdragon, all the benchmarks shows this, just as they show that the 8 core exynos scores higher in multithreaded scenarios. The rest about development etc is because Samsung doesn't release the proprietary hardware blobs we need to get a proper aosp/cm port working. Meaning we have to write them from scratch which takes forever. Qcom has always provided these in the past. The GPU also performs better in benchmarks, whether there's a noticeable difference in real life remains to be seen, still from all evidence the snapdragon beats out the exynos GPU. And my experience with the 7420 taught me that the small cores can have trouble keeping the ui smooth at all times, and we see the same cluster again on the exynos, only on a slightly improved node. Hopefully this explains the logic behind my post better.

Could very well be that the sd820 endas up faster than the exynos 8890 in day to day tasks, but the sd820 seems to be using a lot of mW in comparison to other SoCs(check anandtech's look at the mi-5). Its single thread performance is better, but on average there's only a 10% difference and the exynos is clocked lower than reference (2.7ghz and 2.4ghz). Both modems achieve the same speeds so the only thing that is going to matter in the end is efficiency. Still need to take a look at the GPU throttling on the 8890, as we only know the sd820 GPU throttles at this point in time. Personally I would have preferred the sd820, but if the 8899 brings better battery and better audio quality the difference in performance is worth it. Looking forward to anandtech's in-depth comparison! Don't really get why we haven't seen any reviews yet even though people have the phones already.

Also awaiting the deep dive on both. Keep in mind though, that 2 of the 820s cores are clocked at 1.6 and have less l2cache to save power, and 2 of them are at 2.2ghz, so clock for clock they have very high performance. As for the power draw comparison, it was only an estimate to begin with, and ones got 4 little and 4 small and if it was only using the 4 small during the test that alone would be a noticeable power draw difference. It gets pretty complex with these big.little setups. I've also noticed the snapdragon version has a pretty high load average which should be able to get lowered with some modifications to the kernel.

Yup my SD820 is running full on SPay, Bluetooth, WIFI, NFC, Always On Display all without power saving mode and I get 8h SOT in 24h. Listening to a few posts of people beginning to learn the phones quirks within the first few days is not evidence of anything other than the phone being broken in. Spreading information like this gets people buying devices for unsubstantiated reasons. Please provide evidence if you're going to post stuff like this. You guys are just starting an echo chamber quoting each other with no evidence supporting your rumors.

I never believe people when they say they get 8 hours of screen on time.
And if you read my post carefully, you'll see the fact that I stated the SD820 still has great SoT, but just that there are issues with the Android system draining an alarming amount of battery percentage. This is not some baseless claim, there are multiple posts in the battery life thread showing the android system taking up 35%< of the battery.

Again, it's just a strange thing that can maybe be fixed by a software update.
And while we're at it, how about you show screenshots of your supposed 8 hours of SoT?

What makes you think that only 4 cores are working?
I don't know in the Android world, but in PCs the applications must be written expressly to use more than one core. And the SD 615 has 4 cores that runs at 1.7 MHz max and the other 4 at 1.0 MHz max, but the frequencies could be lowered by phone makers to increase battery duration.

Yeah but I had my phone on performance mode and it's using half of the cores, if the other 4 max at 1.0mhz then why are all games that I play (3D Wise) are slow? Is there any way I could fix it? Could overclocking via CPU managing apps (using root,) work in my situation?

Four cores are high-performance, and four cores are low-power. The performance cores suck up a lot of battery, so not for use with background tasks. The low-power cores are useless for pretty much anything but background tasks, so they're not for use with gaming, etc. The fact that your apps are only using four cores is normal.
Also, as for your gaming performance, I've actually done some testing on this and it turns out that on the ZE551KL, the GPU is way underpowered. No amount of overclocking can fix the abysmal GPU performance on the ZE551KL. This doesn't seem to happen on other models, either, so... yeah.

@gyropepsi: yes, that's correct, the eight cores are not "equal". You have four cores for general CPU use and another four for higher CPU use. They cannot be used in the same time, they get switched to save power. It's actually called "dual quad-core".
https://www.qualcomm.com/documents/snapdragon-615-processor-product-brief
Other manufacturers have one core for low processing and four for high processing. Those phones are doing great in tests but they really suck in daily usage.
@sensi277: I would't say abysmal performance, but yes, it seems to be lower than the Selfie in some tests. However it moves VERY good for a phone, 3D tests on phones are just for kids, to brag about their phones. Nobody does real gaming on a phone.

Almost jumped ship -_-

So yesterday, I picked up a used Alcatel Onetouch Idol 3 Octa-core phone. Has a snapdragon 615(4 1.5Ghz and 4 1.0Ghz processors) and we thought Amazon went to extremes, ha!! Turns out with the M 6.0.1 update, Alcatel not only locked everything down, they even stripped fastboot commands!!! Well anyhow as far as things weigh in, I swear the R1 still feels faster than the Idol 3. Now if I want to continue to play with the Idol 3 fortunately there is a way to downgrade and then flash over a different M rom, that may help. But for now the R1 will remain my daily.

I bought the BLU R1 without knowing what to expect and so far I'm impressed. It's my first ever BLU and Mediatek phone. I hate Snapdragon and avoid every phone that uses it. R1 HD is really fast and responsive. There is a video on youtube showing gaming footage on Moto G4 and it sucks really bad. Idol 3 and G4 are using the same slow, overheating Snapdragon 615 (617 same thing) and claim it's a high performance octa core processor.

I agree, the performance of this phone does not feel as responsive as I thought for an 8 core(4x1.5,4x1.0), the 4 core 1.3 6735 honestly screamed. The Idol runs a 64bit Android 6.0.1 build where R1 is 32bit. Still I agree the R1 felt snappy. The area the Idol 3 shines in though is the Audio dept. Sound is awesome on this thing!! I won't be gone too long, I enjoyed the freedom of experimenting with the R1, practically indestructible until 6.6.... But never repeat NEVER install an OTA until you inspect what its doing!!!

I don't even get why phones apparently "need" an 8 core or even 10 core processor. You can't even do most of the things on a smartphone to max those cores out. I personally believe a quad-core is all that is needed and they need to work on the cpus so that they are better at doing more instructions per cycle so that single-thread and multi-thread will perform even better.
I love the Blu R1 HD and that screen is actually something to gawk at. You would never expect such a screen in a sub-100 phone as this screen can even best some of the high end phones of 2013! My only complaint about this phone is the battery, it has been 19 hours and I have used it for 2 hrs for SOT and it is dead, originally the battery was way better. I don't know what has happened because there is no report of it using massive amount of battery. The awake line is not there when it is draining rapidly and there are no wakelocks keeping it awake as shown in Wakelock Detector.

So far as I understand (please correct me if I'm wrong), multiple cores allow for better power management.
So if you have 8 cores total, 4 powerful, 4 energy efficient, but are idling, then you can turn most of them off to save power. When more power is needed, the more powerful ones kick in and do their stuff.
Aside from that, I assume it is partly due to the difficulty in manufacturing CPUs. For example, Intel chips tend to have less cores (typically 2, hyperthreaded to 4) compared to AMD (often 4 or 8), because their CPUs have strong single core performance. AMD makes up for this by using more cores. I expect this is the same in the mobile computing world.

That certainly makes sense, but in operation, it seems something was poorly implemented because, although this device specs out higher than the R1, in real world use it just seems to be on par with the speed of the R1, plus the R1 screen though smaller definitely appears more vivid and colors pop much more so than the Idol 3. As previously stated by me the Idol 3 has a much nicer audio experience, both in volume and in sound quality, but performance wise, I still think the R1 is superior.

Damnit I bought an Idol 3 and killed the R1 HD, lol

i try run all test and i dont see one time the big core work, they are stopped every time...( try pc mark but dont work he crash after 4k encoding video) with kernel auiditior i can active all 8 core...now they work everytime and i can set governor for each processor...
but other app like cpuz dont find the first processor they see only the last 4 core... ok maybe with bench i can see all cores work but is very hard find a way for check the correct work for governor and the phone processor work fine....
if u dont have root cpu app dont find any governor...or see only one processor...

Those are limitations of the apps themselves or your OS.
I have the official N (rooted with ElementalX) and CPU-Z sees all the cores.
Also there are never supposed to work all 8 in the same time, only a group/cluster of 4 at one time, it is not a straight-up 8 core CPU. They are not "equal" in respect of performance: https://en.wikipedia.org/wiki/ARM_big.LITTLE
Different combinations of Governors and Schedulers produce different results.
PS: The newer Snapdragon 625, that is present in G5 Plus, is listed as a true 8 core: https://www.qualcomm.com/products/snapdragon/processors/625

The 617 is a big.LITTLE octa-core, not a true 8-core CPU such as the 625, like @SoNic67 said. The 617 has one cluster running up to 1.5-1.6 GHz (depending on the kernel), and one cluster that generally runs from 500 MHz-1200 MHz.
The little cluster, or the 500-1200 MHz cluster, is fine for basic tasks, such as UI, scrolling, etc. However, in games, all cores will online (or at least that's the point). Some apps are not threaded for 8 cores and thus will not utilize, or need, 8 cores.
Also, in reality, the 4 "big" cores make very little difference in terms of performance. I did 2 benches in another thread, where Antutu came up 40K with 4 cores and 45k with 8 cores. Although this seems like a large performance decrease, without the big cores the phone was cool, still ran quick, and drained far less battery.
Finally, having 8 cores also can introduce performance deficits as well, especially if your hotplug is inefficient (there may be delays in turning on cores, resulting in UI jank). I thus recommend simply leaving them off- better battery, cooling, and still decent performance.

thx for support and continue OS is amazing gw.
