The notes dual cores - Galaxy Note GT-N7000 General

Are they true dual cores and run at the same time? My evo 3D is dual core but the second core only kicks in when needed so I don't consider it true dual core. Do our cores run simultaneously or like the evo 3D?

Why do you think the way EVO 3D works is inferior? AFAIK, they all work in similar fashion to reduce battery consumption.
Without ICS, all Java based Android apps can only use one single core anyway. Only native apps (like 3D games) can take advantage of dual-core. That's the limitation of Dalvik JVM for Android 2.xx. You will need Android 3.xx or higher to get dual-core support on JVM.

Power saving allows the 2nd core to go into sleep mode, even at fully idle in 200Mhz mode it consumes power and yes its a true dualcore. If you wan you can have both cores running at 1400Mhz 24/7

In power saving mode,I get a quadrant score of only 2600 compared to 3800-4500 with power saving off.
I definitely agree that the Note shuts down one core in power saving mode.
On my wifes s2,power saving mode scores around 3200.Power saving off gets around 3400.Not much difference.

It's called dynamic hotpluging and yes that is how the Exynos works. Why would you want both running all the time?
If you want the ability to have both constantly on, search for tegrak's dual core app in the market. You can force both on with that. You may need kernel support though.

DHD vs O2X which one your favourite?

I own this 2 beast and I also quit confusing to compare this smartphone which is the best one. I like the speed of O2X, but dislike it ui or interface if compare to DHD htc sense. I also like DHD aluminum body more than O2X plastic. So, what do you think guys? which one is better?

Any one? just to know your opinion.

is there a massive speed difference?
Well the biggest difference is probably that Dual Core processor of the O2X (2 x 1GHz) while the DHD only has a single core (also 1GHz).
The main camera is similar, but the O2X is capable of 1080p video recording AND additionally has a front faced camera for video calls.
It has also got more internal storage (8GB) and a slightly better battery (1500 mAH)
So yeah, I would say that the O2X is better than the DHD.

yeh but it has an extremely buggy ui. the speed test show it beats the dhd in web browsing by 1-2 seconds. also some benchmark test show the dhd scoring higher.
also the dualcore phones dont have 2x 1GHz cpu... the total speed is 1ghz
so its (2x 500mhz) this is more efficient than single core.

Say what?!
A 1ghz dual core processor is not 2 processors running at 500mhz!!! It is a single CPU with 2 cores capable of processing separate threads. It runs at 1ghz and technically it is like 2 1ghz processors operating in tandem.
Shoot whoever is spreading the above misinformation lol.

He is definitely right.
You can't just add the speeds of two seperate cores up. The dual core runs at 2 @ 1Ghz. That's like two seperate CPUs, each with a clock speed of 1Ghz. So it is NOT 2 Ghz CPU but rather 2 processors @ 1Ghz. It may sound similar, but it makes a huge difference (for further detail you should look into how a processor works and what threads are).

Just google about dual core vs single core.
You will find info where dual core freq is same as single core. The only different is that dual core is way better when doing multitasking (avoid hang or jitter) and not to say double speed but can say nearly double speed.

Im not an expert but correct me if im wrong.
1 CPU with 2 core. Each core have 1 ghz freq. 1 core to do 1 task, another core to do another task. Meaning freq each core still 1 ghz but since its have dual core it can do both task at the same time. More quick than a single core. If we compare to single core with 2 ghz, it can only do task 1 at a time. In term of speed i think dual core 1 ghz should be nearly the same as 1 core 2 ghz. I also read some where saying single core 2 ghz consume more power than dual core 1 ghz.
Just my 2 cent.

I'm 100% sure. Here's a brief history of multi core processors for those who are interested.
In the late 90's and early 000's, processor speed was constantly on the rise. Manufacturers were trying to out-do each other in regards to who had the fastest clock speed.
The way clock speed increases is by actually shrinking the microarchitecture (Semi-Conductors) of the processor, which leads to faster data transfer/processing rates. There was a pattern involved where each new generation of chip architecture yielded almost twice the clock speed of the past generation. However, as processor architecture grew smaller and smaller, eventually we approached a stage where physically, using current materials and manufacturing processes, a limit had been reached. It wasn't possible to continue shrinking the size of the processor, so logically, the next step was to integrate multiple cores on a single chip. This was the birth of the multicore processor.
The way a multicore processor works is by utilising multiple processor cores on a single chip. This way, instead of a higher clock speed, you have multiple cores running at the same speed, 'sharing' the workload. So, a 1ghz Dual Core Processor is a single chip, with 2 cores both clocked at 1ghz. A 3ghz Quad Core Processor is a single chip, with 4 cores all clocked at 3ghz.
This all sounds wonderful, but for a multicore processor to be used efficiently, it requires software to be multithreaded. This is where you have to question the use of dual core processors in smartphones, as none of the applications or the OS utilise multiple threads! So really, as it stands, you'll struggle to see truly improved performance from dual core handsets.
This will all change in the future. Android 2.4 will support dual cores by default and I'm guessing most software will start to aswell.
Anway, hope this was interesting for those wondering how dual core processors work and about clock speed etc.

Well i have both phones now... i missed the sence weather and clock from DHD but fancy widget fixed that. O2x still has a few bugs ie black screen and auto reboots but i only had 1 bs a 2 reboots in 2 weeks now . games work better on o2x also with normal lock screen o2x is snapper all over at stock than a oc to 1.2 ghz DHD but the best part is the real HDMI out (no need for a ps3) but i will keep both phones

-screen on: 1.4 Max/1.4 min
-screen off: 100
-in call: 100
-battery below 20%:100
-battery hot:100

I just use the dual core app to enable dual core mode, not overclock. Its an app that has 3 modes: dual core mode (both cores running all times) , single core mode (one core running at all times) , and regular mode (where 2nd core kicks in when needed) . I like the extra umph of dual cores smoking simultaneously

Quad-core or 2gb ram?

In real phone scenario what we could benefit more? Will a quad-core be faster the 2gb of ram? Or will a 2gb will perform better against quad-core?
Pocketnow did a video between the gs2 and gs3 and both were opening apps really quick, they were really close on browsing, gaming. Do you think the 2gb will make a difference on the phone compare to the international? What are your thoughts?
Sent from my SPH-D700 using XDA
2GB will help with multitasking while the faster processor will help with gaming and to a degree, faster apps.
If it were an iPhone, then the quad core would be much better because apps will actually make use of the amazing gpu. In android, I doubt there will be an app released in the next year or two that realistically benefits from the quad core's gpu vs the dual core's.
Both the dual and quad core will have all of the software optimizations Samsung has done for web browsing. The 2gb memory is probably overkill at this point, but in theory it means that apps will never close in the background since there will be no need to free up new memory.

Here's my thoughts:
1. Still on the Epic 4G I've never had any real lag.
2. Lack of ram can stall a device, but an excess of ram will not make it faster.
3. Mobile quad-cores are new and untested.
4. Android is not designed for quad-core processors.
5. The dual-core US version should easily match the quad-core international.
6. More ram means more easily multitasking/app-switching.

1. Well the whole android cant handle 4 cores i think is false because its derived from Linux and i know those who use 4,6,8 core processor's and use Linux. so if android isn't im sure its all in code is all.
2. More Ram does mean things will run much faster. For Example: playing gta 4 with 4GB of DDR3 Ram @ 1333MHz plays decent but my pc setup that plays gta 4 with 8Gb of DDR2 Ram @ 1333MHz plays faster and loads faster but GPU does factor those speeds too so, in a sense you cant bottleneck them.
Extra RAM. It's going to be a while before the apps/software catches up with having two more cores. Meanwhile even old stuff can benefit from extra memory. Also see it as more future proof as you won't get the lame ass excuses from Samsung about it not having enough RAM to run whatever the latest release of Android is like we got with ICS and the Epic 4G.

You've misunderstood. Android can use 4 cores, of course. What it can't do is use them effectively in a way that creates any sort of advantage. But just as a mention, being derived from Linux source does not make it a full-fledged Linux OS by far.
And on your second point, again, you're comparing to a full PC operating system. Up until now, apps have been designed for phones with far less than 1GB of ram. It really depends on how you use your phone as to how much ram is needed. If you have a video editor running in the background, while playing pandora, and emulating Mario 64 you'll need more than simply browsing the web. But the processor, bus speeds, operating system, etc. all factor into how effectively more ram can be used. For Example: A 32 bit computer can't even use more than 4GB of ram. More ram does not simply mean 'much' more more speed, there are many other limiting factors. You can throw all the ram you want at a netbook, it will never run GTA4.
Off-Topic Edit: I vote 2GB ram over Quad-Core.
I guess then the only thing that will "improve", not that the int'l lacks of, is on the multitasking??
The few videos I saw, they were really fast but that's of course without all the apps that a normal user install. Like I have 38 apps install on my phone and most of the time I open between 9 to 13 apps everyday. Most of the time I have to close it...I guess more for the habit of doing it and of courses need it when playing games.
I read the answer and I kinda feel its true, maybe android is not yet ready for such hardware just yet, does it feels the hardware manufacture is going too fast compare to the software?

There will be improvement between the dual-core, faster processor, and more ram, rest assured!
Although I still recommend closing apps unnecessarily opened to save battery.

I would take the dual core Krait hands down because it is designed from cortex a15. More instruction per clock is better than stacking cores which a phone doesn't even use. I think the 2 gb of ram has more performance advantage.
They also increased the memory bandwidth with new SOC by adding a new dual channel memory controller which the exynos had all along... They fixed alot of the shortcoming of snapdragon processor with the this gen product

That's because Hummingbirds rape Snapdragons. See the following:

Either way if you want LTE at the moment you are stuck with dual core. So the 2GB of RAM is a nice enhancement. The EVO 1x ended up as two models the 1X which is quad core with no LTE and the 1XL which is dual core with LTE.

Where the hell did the epic4g or the iPhone 4 come into the question? My point was that iPhones actually make use of their gpu's better than android phones do, so the difference between the quad core and the dual core gs3 should be minimal in that regard, at least for a while.

This is wrong.
The Krait is very much designed from the Cortex A9. While it shares similarities with the A15, it is not quite as powerful.
Krait is about 60% of the way between the A9 and A15.

No, where'd you even get that from? Krait is slightly below an A15, Qualcomm derived their design from it. Yes, its not a true A15 core. But its the best right now in production.
Qualcomm has a license to mess around with ARMs designs and make their own CPUs, not just copy and slap an "A4" on them like Apple does.

Interesting how someone "Likes" wrong information.
http://www.anandtech.com/show/4940/qualcomm-new-snapdragon-s4-msm8960-krait-architecture
Designing a processor takes an extremely long amount of time. A15 was just barely released a few months ago. No way Krait was designed from it.
Now, Krait borrows some features from A15, but it's missing some important features as well. Krait does feature an extended instruction pipeline over the A9 (11 vs 9 cycles), but it's nowhere near as long as the A15 (15 cycles). Strictly speaking, lengthening a pipeline is less work than shortening it, hence Krait was not designed from the A15.
It's more likely Krait is an evolution of the Scorpion than anything.
As far as Apple, they have no place in this conversation, but if you must.... while they do have a "processor-only" license with ARM, they do farm out to a company to change some transistor signaling to make it more power efficient (they later bought them).
2 years ago, Apple bought Freescale, the only remaining PowerPC processor design company. (aside: The defense industry was largely concerned, as they rely on PowerPC for their power-efficient but high-speed applications). Anyhow, I wouldn't be surprised if they have an architecture license now so they can design their own ARM processors, Qualcomm-style. The main advantage would be integrating LTE radios like Qualcomm does.
Coincidentally it takes about 2 years to fully design a processor.

Sony experia Z ONLY QUAD-CORE 1.5GHZ ??

So I've been noticing somethin strange other then the experia z every single other high end device that will come out as of 2013 will be using a 1.7GHZ snapdragon the only high end device that will use a lower one is experia z why????? I mean the phone hasn't come out yet can't they just put the 1.7GHZ instead? why use a lower one 1.5GHZ from phones of the fourth quarter of 2012 its old tech!!!

Calm down man, 1.5GHz quadcore is good for Android. Android really doesn't need such a high speeds
And CPU clock doesn't mean smoother device

1.5Ghz Quad Core is not "only". And they all use exactly the same CPU which operates with 1,5-1,7Ghz speed. Clock speed isn't everything. Look at the iPhone - it uses dual core 1.2Ghz CPU - yet its performance is 5 times smoother than most quad core devices...
Dual core is more than enough for anything a smartphone might need to do - as long as you put good software on it.

Seriously? "Only" on a quad core 1.5ghz CPU for a smartphone? What are you gonna run on your phone that would require you more? Or do you just want your battery to drain more for no possible reasons? Some users even just underclock for the sake of saving battery.
If you ask me I buy this because of the features and the RAM not because of processor clock.
If you ever let me choose I would rather go for a 1ghz dual core processor with 4GB RAM than having a 2ghz quad core processor with 2GB RAM.
The only reason why I would want the Qualcomm S4 Pro processor is because of adreno 320.

What would be the purpose of 4GB of RAM in a smartphone are you running Photoshop or a VM? Where did this stigma that more cores is equivalent to less efficient power use. More asynchronous cores allow for more accurate scaling of processing power to needs, thus higher power efficiency because the CPU spends less time in higher power states.

Buddy android runs Dalvik VM and our GPU uses dedicated RAM for processing certain graphic tasks. So yes we are running a VM on our mobile phones.
Also with a proper monitoring app you could see for yourself which uses more and needs more resource here. whether processing or memory.
Didn't you even wonder why our phones consume almost 700mb RAM without even a single foreground application open? Yet it sits idle in a single core and remains in between 400mhz+ to 900mhz?
Also I didn't say that more cores consumes more power in my statement but still since each core requires power to run it should also consume more. Also I didn't mention anything about number of core I was talking about the clocks. Since the higher the clock requires more Amperes. Still underclocking your phone by 500mhz would prolly just save about 2% of your battery anyways.
you don't need higher cpu clock to get a pocket heater for this winter
My Optimus G has the same cpu an the thermal throttling is kikin in pretty fast. This 1.7Ghz S4pro will thermal throttle as fast or even faster, rendering numerical advantage meaningless.
I don't want to feed the troll but I also think dual core is good enough.

I have yet to see my Xperia ZL have less than 800MB of free an extra 2GB would be a total waste. And you simply stated you'd rather have a dual than a quad, peak frequency means very little except for potential processing power. Just because your CPU is capable of a higher clock speed doesn't mean it will idle any higher. Likewise the only difference between a quad with a single utilized core and a dual with a single utilized core is the minute amount if extra leakage current for the quad.
I think you meant to say that higher frequencies may need more voltage, amperage has very little to do with CPU frequency scaling.
And obviously the memory overhead for a virtualized process i.e. Dalvik VM is not even in the same league as a system VM.

Buddy that 800mb is without running any foreground applications other than either Settings app or the homescreen. Like I said try running some monitoring apps on the background and try using the browser then maybe try loading some sites with lots of javascript codes in it.
Or if you like try launching 4 types of angry birds and the 2 temple run games simultaneously without killing one of them and let's see if OOM doesn't kick in and kill any of them.
Regarding CPU cores please state something that requires a quad core processor. The smoothness of the UI your experiencing is because of the type of processor your phone is using "The Snapdragon S4 Pro" even if you disable all the extra cores in it you won't feel anything different unless of course you'll run some benchmark tools or video decoding stuffs in there.
And just FYI more cores doesn't mean greater processing power. It's more cores = more processes it can handle.
And on the CPU freq clocks who said t that amperes doesn't increase on each frequency table? Please take a look at qualcomm's document on their site regarding it's processors so you would know how they calculate it. Voltage is just used to provide more electricity to power up the processor but voltage alone won't make a processor active.
This discussion is going to the wrong way.

CPU/Processor Showdown - HTC One vs Galaxy S4

Which processow will be better, Exynos 5 Octa or A simple Snapdragon 600 quad?
In my POV, Octa will be useless since it will be a battery hog and no apps really use that much cores and power. The S600 will be more efficient for day-to-day use since it consumes less power and will actually be used.

[Info] Exynos Octa and why you need to stop the drama about the 8 cores
AndreiLux said:
Misconception #1: Samsung didn't design this, ARM did. This is not some stupid marketing gimmick.
Misconception #2: You DON'T need to have all 8 cores online, actually, only maximum 4 cores will ever be online at the same time.
Misconception #3: If the workload is thread-light, just as we did hot-plugging on previous CPUs, big.LITTLE pairs will simply remain offline under such light loads. There is no wasted power with power-gating.
Misconception #4: As mentioned, each pair can switch independently of other pairs. It's not he whole cluster who switches between A15 and A7 cores. You can have only a single A15 online, together with two A7's, while the fourth pair is completely offline.
Misconception #5: The two clusters have their own frequency planes. This means A15 cores all run on one frequency while the A7 cores can be running on another. However, inside of the frequency planes, all cores run at the same frequency, meaning there is only one frequency for all cores of a type at a time.

Addition: I am not a Samsung fanboy by any means, however, the amount of incorrect information floating around about both of these flagships is starting to get annoying.
2nd addition: Read this as well, the big.LITTLE technology being used in the Octa is pretty amazing: big.LITTLE Processing
I hope that the overclocking or higher clock rate doesn't produce Moment-esque results.

In the US that is true, they are both S600's, with the S4 having a .2ghz higher clockspeed. Many of the other S4's will have the Octa Exynos chip.

Ah. I see. Different hardware for different regions. Like the One X.
Even though it's eight cores it is probably complete overkill. Yet another bigger number to put on marketing. How many apps will actually use that? How many apps use four cores at the moment?
There have been some articles about multiple cores being more for point of sale than for the end user. Even if you're signing up for a contract right now I doubt that much would be making use of it in two years time. So, the future proofing argument is moot.
It'll be interesting to see. Of course the galaxy builds of Android will use the cores. With things like the stay awake feature and pip it is useful. Outside of the OS I can't see it being necessary.

The "octa" core processor is complete bullsh*t. Imo, 2/4 cores are perfectly fine as long as they optimize it and perfect the hardware, why stack 8 cores when only 4 work at one time and no app will use all that power.
They should've focused on design to make it look less like a toy phone and use better finish, instead.
Oh the marketing..
Not HTC or whatever fanboy, just stating my opinion.

Very good read, thanks for taking the time to post it. Surprised no-one has mentioned that we need this in our Ones. Would certainly help with the battery.
Saying its a 8 core cpu is marketing simply put.
Like it has been said only 4 out of 8 cores will only ever be enabled at once max.
The GPU on the Octa might be better then the Adreno 320 but its have to wait for benchmarks.

Those are from the S600 version.
Higher clock speed and Android 4.2 will mean its slightly ahead.
No benchmarks from the Octa version yet.

"Octa" is not gimmicky or for marketing.
Octa is the name of the SoC, and how it was named is nothing wrong
There are 3 implementations can be used, and one with maximum 8 cores running at the same time.
GS4 doesn't use that impletations, but it does not mean the SoC cannot be "Octa". You have a house with 8 rooms but you know to open or you wanna open 4 rooms only, the house is still an 8-room house.

How do you know all 8 can run at the same time? Has Samsung demonstrated that already? Any links?
Also what would be the speed if all 8 are running at the same time?
Also did you see that an Intel dual core @2GHz beat the Exynos Octa in benchmarks!!! So all 8 cores running at slower speed might not be very good actually. It might even slow down things even more...
We recently demonstrated a dual core running at 3GHz at MWC in Barcelona. That chip was able to load games at crazy speeds. A game that took 15s to load on existing Exynos Quad core was loading in just 6s with our chip!

Its all about bragging rights really. Same as Samsung is doing with regards to Octa.
The the chip that could run at 3GHz could also very well run at 1GHz at just 0.6V (so consuming far lesser power than anything else in the market). A dual core at 1GHz is still good enough for all mundane tasks like playing videos or internet browsing etc. So in practice it would have been a very efficient solution. It was a real innovation really. Sadly the company did not have money to pour more funds into the program and has shut it.
It was demonstrated at Mobile World Congress in Barcelona in february this year.
Anyway point is, we did not need extra set of power efficient cores like Samsung is doing. We ran the same cores that could do crazy high speeds and even crazier power efficient mode! Thats a very neat solution.
Heres a press link: http://www.itproportal.com/2013/02/25/mwc-2013-exclusive-dual-core-st-ericsson-novathor-l8580-soc-crushes-competition-benchmarks/

Actually, no. At least not in my opinion. Octacore means 8 cpu cores on one cpu-chip.
I would see it like this:
You have 2 houses on your lawn which are beside each other. Every house has 4 rooms. You have to switch houses to open up the rooms. Just like the Exynos "Octa" has to, since it cannot run both CPU's at the same time.
If you are in a house with 8 rooms, you cannot simply be in all 8 rooms at once. You can connect the open doors between all the rooms, and since your in that house, you can freely walk in every room. But not with that implementation.
I wouldn't call the Exynos "Octa" an Octacore, its a dual CPU system with a 2x4 cores, with the difference that regular desktop dual CPU systems can use both CPU units at once, but not like the Exynos "Octa". Still, dual quad system comes closer than a pure octacore system.
This is kind of a hybrid. Nice technology for a mobile device, but at the same time, kind of unneeded / inefficient, compared to regular quadcore systems. Even the Tegra 3 system with 4 active cores and 1 companion core for standby tasks seems more efficient (in terms of "used space" and ressources).
Ah well let's see how the supposed and so called "octacore" will score in the future...

okay I know both processor are snapdragon 600's but why is the galaxy S4's processor clocked at 1.9 ghz and the HTC One's processor is clocked at 1.7 ghz is it just an instance of samsung overclocking the s600 or are they different variations of the same processor, I have done some research and am able to find no clear answer to this question even on the snapdragon website????????

They should be identical. I think its just a manufacturer choice. But it could also be associated to termals or battery.
Cause Samsung took the higher frequency chips, there is the possibility that they also get the "better" chips: Lower Voltage for the same frequency. But thats just an assumption.
