I bought this phone because of the quad core 1.9Ghz processor, but as a matter of fact, this phone is a quad core 19ghz processor only for 5 or so minutes at a time, then it's just a 1.2Ghz quad core processor.
I don't know what's the reason for this, but I suspect overheating or Scamsung being shady and still cheating the benchmarks.
Anyway, try this: download Antutu Benchmark (or any other benchmark really) and run a full test: if the phone is "fresh" you'll get 29000 or so points. Good. Now run it again, you'll get less, and if you run it again, you'll get even less.
What do you think is the reason for this? This phone is unable to keep it's maximum frequency for more than 5 minutes at a time, and so it underclocks itself to 1.2Ghz (check it with CPU Z or anything, it will never go to 1.9 ever again after you get the lowered score in Antutu) and stays there for hours before it goes back to 1.9 again.
Check out these screenshots, and look at the time I ran the benchmarks. It only took 3 minutes to go from 29000 to 26000, then I ran it 2 more times and it went as low as 22000 with massive performance losses in 3D graphics (OpenGL test runs at around 30-40fps the first time then 15-24, basically half speed).
If this isn't a scam I don't know what it is. They should have advertised this as having a quad core mode for 5 minutes every now and then, or being a real quad core only in winter, because as a matter of fact it runs like a mid tier dual core most of the time. No wonder the UI lags like crazy all the time after you browse the internet a while or play a 3D game.

This is not scam. This is **** done by samsung in 4.4.2 update. They enabled something called dynamic voltage and frequency scaling.
There is a xposed module to disable it.

Really now. I need to try this, because right now I'm MAD. I had a similar problem with the Xperia S that happened only when playing and charging at the same time, and you can't believe how angry I was at that.
Since I bought the phone just recently and it was already on KitKat, and I did some googling for i9505 and overheating and all sorts of related keywords and found nothing, I expected this behavior to be pretty much undiscovered. I'll try the exposed module and report back.
Anyway, since you need root, and mods, the phone is still a scam because the average user wil NEVER EVER figure this out on his own. It's advertised as a 1.9Ghz quad core when in reality it never runs at that speed.
I confirm that it was caused by the DVFS. What were they thinking when they implemented such a thing on the phone?
Facepalm.

1.9 ghz is it's max speed which it does achieve for first few minutes when a game runs and hence it is not a scam. No mobile processor runs at it's max frequency 24/7 or else you would have to keep charging the phone every hour and the phone would probably die in a day due to overheating -_-
Samsung did this to increase battery life but the move backfired
The only way you can do something about is by rooting the mobile which infact will void ur warranty.

It should run max speed when needed, of course it won't run at full speed all the times, but if it runs at 1200mhz when I'm running a game or the browser and it's lagging like crazy then there's a problem.
I already rooted, voided my warranty, tripped my know, and fixed this issue with the xposed module the other user recommended.
Bottom line, unless you void your warranty and install user made mods this phone is a scam, because as soon as it get slightly warm it underclocks like crazy causing lag and horrible performances. There should be lawsuits up the ass about this. Users shouldn't accept having their phone arbitrarily underclocked for no reason like this.

so the pattern is doubling the number of cores every generations then the next generation should have 8core processor?
I highly doubt it...
Probably a hex core.
Swyped from my OG Droid running CM7
I just noticed this in Tapatalk new posts, and just HAD to answer.
What's the point?
Name one situation where you would even need that.
Samsung needs to work on improving other practical features.
They've always upgraded what makes people fall for their phones, but never anything actually useful.
Years ago, their phone cameras went up in megapixels, but sucked no matter how much megapixels they had. Because megapixels aren't as important as is other more technical camera features. But megapixels are easiest to advertise so they went with those.
Personally I think a single core was enough. Now, phone companies need to work on RAM. They could stuff a lot more RAM in before they need to upgrade the processor.

Doubt it. these apps doesnt even require 8 cores. if any of these phone users require 8 core just to play games, either get a console or a decent pc.
8 core to play Angry birds or Shadowgun...pffftt...
will 8 core make me type faster?
Just Faster Speeds
tbh, I think faster speeds are really the only shift we'll be seeing at least next year for sure, but probably the year after that as well. Although with Windows 8 on ARM on the horizon, perhaps devs may find a way to do some serious mobile computing.
i don't think that 8 core will be useful for a device of 5" or 6"
They will stay at quad core but use the faster A15 architecture.
It's possible they might add some low powered A7 cores in a big.little configuration to improve battery life.
It will also have a next gen Mali gpu. Either Mali 604 or t658.
I'm also expecting it to have 2gb of ram.

I'm not entirely convinced multi-cored phones of any variety are even really getting fully utilized yet :/
I honestly believe cores are more of a marketing gimmick at the moment. I could be wrong, I'm no expert and I don't have the ability to see how well android handles the fine details.. But, there are a lot of factors most people don't even think about when buying phones.. Manufacturers know you're not going to ask "Well what about this 1.5ghz single core processor preforming 4 instructions per clock compared to this dual core phone performing 1.5 instructions per clock?"
Maybe when I go to upgrade my captivate I'll worry about cores more but, at the moment I wouldn't be surprised if dual cores were preforming better than quad cores since they have been out longer and had more time to get optimized in the code.
Dual core phones are already fast enough but seems like phones will start competing with pc in the next few years.
Imo RAM n battery life need to be increased greatly then manufactures should start thinking about future multiple core cpu.
Imagine a hex core cpu n the juice it needs
Yes, RAM!
ya, I definitely think RAM has a place because that's one of the best things about smartphones is the ability to multi-task! So if manufacturers can further cater to that, then I think more cores may follow, especially if we get more TRUE multi-tasking where you have live apps running. Because then, you can delegate individual cores to individual apps that are running. ATM I'm not entirely sure why I would need multiple live apps running simultaneously on a phone, however I think for business workers/students it could be helpful to be watching a live stream or doing a conference call while taking notes in an office suite app.

Instead of wasting money (which I don't have) on a newer phone, I work on optimizing Android to run at its best on my phone. Look at the Sony PSP. The XMB is amazing for a 333mhz processor. (And its actually clocked at 222mhz at the XMB). Now, were not talking about the browser here, that sucks. Sony spent time on the OS itself. They won't get thanked for it by the people who look at the features list on the box, but they engineered a wonderful OS for such a weak device.

Hehe, I know what you mean...a year ago I had a Desire, and it was amazing to see how greatly the software could work after some tweaking, compared to stock. Sure it was kinda challenging, but it really felt like it was worth it: that phone was a living thing to me, I could hear it breathing. I swear I almost cried when I sold it, and I actually immediately regretted doing it, but it was too late. It was like leaving a dog on the side of the road or something like that, but at that time I was all excited about the fresh dual core thing, so I couldn't think rationally. There are days when I still feel very guilty about what I did. I'll never do that again. Guys seriously, if you have an old Android device with you don't sell it, you will regret it. Maybe not now, and not even in a few months, but you definitely will, trust me, especially if you've been living with it for a while (I had that phone for over a year).
Selling the GS2 didn't actually make me feel that way, probably because I've only kept it for a few months and didn't really tweak it that much...
8 cores is long way to go.
no way 8 core phone in next 3 years!

I wonder if we really "need" to overclock this beastly CPU of ours? Hell, even if i underclock to 1Ghz, most task if not all are done fast, really fast. Talking about games? Modern FPS games are driven by both CPU and GPU and thus doesnt require much of horsepower of the CPU. Im confuse why numbers of people here are crying "why they are not stable @ 1.8Ghz"? ... Even if you set it @ 1.8Ghz max, our phone will barely reach this clockspeed because other cores will kick-in in less than maximum speed of the primary core (if im right?) ... Is it just for Benchmark figures? Good figures doesnt equates to good performance and we all know that... Can you really sacrifice "Stability" for the sake of some "Ego-driven faaassssstttt BM"?
I swear, some people are just so dense. Why don't we all drive Honda civics? Do we really need a car with over 200hp and can top out at 150mph when most speed limits are 65mph? Why do we bother eating at expensive restaurants when we could save a ton and eat at mcdonalds? People have preferences...it's what makes the world go 'round. If people want to overclock, let them have it.

I actually agree with the op personally and I have been developing on android for four years since the g1, I don't see the need to over clock this phone as it runs really well all of the time,I too had the optimus 3d and that definitely needed overclocking as that was so painstakingly sluggish without it. the only reason I would overclock is for benchmark results other than that its just another drain on the battery for no real world performance gain

Off topic: Optimus3D ROM is one of the most poorly optimize in modern Android flagships... I too had one, running it with AOSP is buttery smooth but also have some compromises...
I am sure you are missing the main idea of overclocking. First of all people normally do it to achieve better results in benchmark. But more and more are starting to do it for better performance and so. Overclocking a phone is useful for the first mainly, I doubt that anyone would overclock their phone in order to play games with better fps for instance. The whole idea is bad, there is a large difference between a phone with minimal cooling and a big ass desktop with 50 fans. If we want our devices to last longer we needn't touch them to make them "faster".
When I can overclock to 1.6gh AND under volt to 50mv below the stock voltage for 1.4GHZ it's pretty much a no-brainer

There is no default for the gpu on m kernel. Over clocking while theoredicly killing your prossesor faster actually can add life to our tablets becuase they will be able to run more recent things when tegra 3 becomes obsolete and we get better games and a newer os in a few major updates. I benchmark in 3dmark a good 3xs stock when in the 600mhz GPU range and 1.7 prossesor clock so i know this will help us run recent stiff. Just wanted to know is there is a nvidia specific """"chart"""" of some kind or manufacturer's guide to safe voltages and clock speed as some dev said" the voltages are high although within nvidia limits" do you know the limits is what I'm asking...

Not saying this is the case specifically for the N7, but there are many corporations out there who would do this type of thing (*cough* intel *cough*).
The game console nvidia shield has an tegra 4i which is far more powerful and can be clocked very high, theres no tegra 3 game console.
Safe OC goes up to 1.5 GHz, but look at one x+ still stable @1.7 ghz and 520 mhz gpu.

All semi houses sell their parts in different speed bins, and a price premium is demanded for the high performance bins. So the OEM gets to decide what the performance range will be - constrained by the price target of their design. The fact that a 2.3Ghz Tegra3 speed bin exists does not mean that all parts have that capability.
In any event the "voltage table" you are looking for is published in the stock kernel source code.
The N7, priced @ $200 never was a premium product. A damn fine value for the money, though IMO.
Hard to believe in the planned obsolescence hypothesis (in this case), as it appears that Google is selling the N7 at a loss. Usually planned obsolescence occurs hand-in-hand with a profit motive.

Back to the topic.... Could someone help me find the sourse code for tegra 3 so i know and others how to over volt to achieve certain clock speeDs
Will overheating ever get fixed? Pretty much all roms I've tried overheats soo much that the phone feels uncomfortable to hold. I'm not talking gaming only but by just simply browsing the Web easily heats up the phone to 40 degrees.
Is this happening to both 9500 and 9505? I own the 9500 octa version.
Use a custom kernel and underclock it so it doesn't overheat as much
I think the heat problem come when the phone release at first, and hard to fix.
You must be can imagine when a machine work, they will produce heat. How if that machine is powerful, and the machine case is thin, of course that machine will make the case hot. That's the case of SGS4 i9500 imo.
So if samsung (or we ?) want to fixed it, they'll have to shutdown few core when the core is really not needed. But if the phone is used to play heavy duty game, all core will be needed and the phone will be heated by the core.

I have a i9505 that's throttling in games, especially if I leave it in its official Samsung case. Is it possible to shut 1 or 2 cores completely off? I think it might be easier for the phone to maintain good performance if it's running with 2 higher clocked cores (due to less heat) versus 4 throttling cores.

Ah, so both brother from samsung galaxy s4 (i9500 & i9505) have the same heat issue.
I didn't know about shutting down the core completely off since I'm not a dev, and I'm new to android either.
Maybe few or alot devs out there already working that out. Me also keep searching for the fix those heat problem, but until now, what can I do is just underclock the phone, some people says by underclocking it (on my device i9500) can make only the little core work, but sometimes I feel the big core also work and make my device warm (I think about 37 -39 C)

Then u surely have a case and u never used a heavy app ...

Actually this is my second s4 my previous one used to heat like crazy but this is much much better.
I play games like shadowgun,asphalt 8 nd most wanted etc those are heavy enuff apps.

I have Android Revolution HD 3.0 and Ausdim kernel v15, its not getting as hot like it used to be.

Undervolted and underclocked.. No more heating issues for me..
Hey guys. I bought the Nexus 6P this week at the same time I finished my new app Face Jacker. The app is quite intensive on the CPU - as it's a camera app and I'm manipulating the pixels from the camera every frame, but something is just not quite right when ran on the Nexus 6P.
I created and tested the app using the Samsung S5 on lolipop which runs the snapdragon 801 cpu. It runs seriously smooth on the S5. I later tested the app on the S7 edge since it was running marshmallow -- again no issues there, app ran silky smooth just like the S5 just as I expected.
Now heres the weird part, I load the app up on the Nexus 6P same day I buy it. The face jacking runs smooth for around half a second before the fps drops from around 28 to 7. Both the nexus 6p and S5 are using the same resolution when running the face jack.
I'm trying to figure out what's causing this serious knock in fps after the first half second... The only thing I can think of is the CPU being throttled. I checked the temps but they around 46 on full load of the app - but this wouldn't be enough to throttle, would it?
The clock speed of one of the cores in the 6P is obviously fast enough to run the algorithm every frame (as it runs fine for first half second) but it takes a serious nose dive for some reason I can't explain.
Does anyone know anything special about the snapdragon 810 cpu? I've read that it can be a beast of a cpu performance wise - but I don't understand why it would run so slower to an older cpu.
Sorry for rambling on, just really stumped with this one and I don't know where to even start to debug this.
I can't post a link to the app since I've just registered to XDA - but if you want to find it, please search Face Jacker in the playstore - it's the one with the purple icon.

It's most likely throttling. From my experience 46°C would easily be enough for the CPU to start throttling back, and even dropping cores completely, in order to control the heat that's generated by this chipset.

Thanks Heisenberg. Didn't realise that 46°C would be enough to cause throttling.
So before I start changing my algorithm - is there any way to bypass this throttling? I read somewhere that Marshmallow causes the throttle -- is this correct?
It's quite frustrating as the device gets warmer using other less intensive apps!

It isn't isolated to a specific Android version (it happens on this phonon LP and M), it is specific to the Snapdragon 810 chipset though. The throttling occurs at a kernel level so to change it you'd need root access and a kernel tweaking app to stop throttling from occurring. Or you could build a kernel that doesn't throttle. But that would need to happen on each device, so it isn't a realistic option for getting the app to work properly.

Cheers Heisenburg. Reckon I gotta either offload to the GPU or change the algorithm altogether!
