First of all Im new to the forum so hello lol
I have a question about qualcomm...I know that the scorpion processor in the next generation 45 nm chip but what I dont understand is why is it clocked at 800mhz?
The made it such a big deal crossing the 1ghz mark and I would assume that they would never look back. I might not have my facts straight but dosent the 45 nm run clock-cycles just like a 65 nm but more efficiently in respect of battery consumption.
It looks as if they wanted to get in on the low-end Android market share. As for the G2 which I love, my friend ran quadrant pro infront of me and it shows the cpu was scored what looked like 20% lower than the nexus one at 2.2 (my guess from looking at it) but of coarse the gpu trashed the nexus one.
I saw a interview on engadget about a week ago about googles executive that said soon there will be a clear distinction or line between low end Android and high end Android devices. I wonder if HTC is in contact with google about future updates in order to release devices adequate enough to run them or are they just blindly releasing high build quality devices lol
Sorry about the long post but I had come up with a few questions that I didn't want to ask anywhere else.
Thanks.
Wait until our geniuses figure out root then you can happily run it a 1 Ghz+. If you look at the spec scheets for the MSM7230 then you will see it's rated for speeds 800-1000. Higher speeds=lower battery life, so the reasons for having it clocked lower are very practical. My G2 can average 1600-1650 on quadrant, so I don't think it's that bad.

MHz is a misleading statistic to judge performance by. A 1GHz processor is not guaranteed to be faster than an 800MHz one. What is always true, though, is that a given processor running at 1GHz will take more energy than the same processor running at 800MHz. Because these new processors are so fast, even at 800MHz, they are competitive or even faster than any other phone on the market today. However by clocking them a bit slower, they also have quite serviceable battery life.
In daily use, it is unlikely that you would notice much difference between 800MHz and 1GHz with this cpu. They are both plenty fast, and most of the time the CPU will be waiting for you, not the other way around. However if it were clocked at 1GHz, you would immediately see a shorter battery life, so to my mind the sacrifice is well worth it.
As far as any fears that this might be a "low end phone", make no mistake, this is the premiere Android phone on the market right now. The Droid 2 may have a higher profile, but it is slower, has a slower network, and uses a non-standard GUI (not to mention a whole lot more expensive when you factor in the price of the service). No phone will have every possible feature that people want, but as far as raw capabilities go, there is no better phone on the market today as far as I can see.
Those seem to be very valid points and thanks for the input..
One other thing when exactly do you need 1ghz of processing speed?? I mean back in the day the macbook air used a 1.5 ghz processor..
Also where dose the ram come into play?

RAM is a far bigger determiner of performance on a day-to-day basis than processor speed, at least to a point. You could have a 10GHz computer, but if you only had 64k of RAM it would crawl along miserably slow.
In either case, there is a point of diminishing returns, though as applications become more demanding that point gets higher and higher. I remember selling Mac's back in the early-mid 90's and telling eople, don't worry, 16Megs of RAM (a huge amount back then when the standard was 4MB) would handle anything they could throw at it. Little did I know that just 15 years later I would have 500x that much in my desktop and 32x as much in my cell phone!
I am by no means a Andoid systems expert, but from what I have read there is not much benefit of having more than 512MB of RAM with the current versions of the Android OS. I would have preferred that they included 1GB of RAM just for a future growth path, but I can understand why they didn't. Each of these features costs money, so you have to draw the line someplace, you can't included every feature people may ask for in every phone.
Your right lol How will the big companies make any money if they give you everything you wanted....
I've never kept a phone for more than 8 months because of updated stats but lately there is a boom in technology so its going to be more like 4 months now hahaha
So with the new Dual Core phones coming out I'm wondering... What's all the hullabaloo?
I just finished reading the Moto Atrix review from Engadget and it sounds like crap. They said docking to the ridiculously priced webtop accessory was slow as shiz.
Anyone who knows better, please educate me. I'd like to know what is or will be offered that Dual Core will be capable of that our current gen phones will NOT be capable of.
For one thing (my main interest anyway) dual core cpu's and beyond give us better battery life. If we end up having more data intensive apps and Android becomes more powerful multi-core cpu's will help a lot also. Naturally Android will need to be broken down and revamped to utilize multiple cores to their full potential though. At some point I can see Google using more or merging a large part of the desktop linux kernel to help with that process.
At the rate Android (and smart phones in general) is progressing, someday we may see a 64bit OS on a phone, we will definitely need multi-core cpu's then. I know, it's a bit of a dream but it's probably not too elaborate.

I'd really, REALLY like to know how you came to that particular conclusion. While a dual core might not eat through quite as much wattage as two single cores, one that takes less is pure snakeoil IMO. I have yet to see a dual core CPU that is rated lower than a comparable single core on the desktop. Why would this be different for phones?
Software and OSes that can handle a dual core CPU need additional CPU cycles to manage the threading this results in, so if anything, dual core CPUs will greatly, GREATLY diminish battery life.
The original posters question is valid. What the heck would one need dual core CPUs in phones for? Personally, I can't think of anything. Running several apps in parallel was a piece of cake way before dual CPUs and more power can easily be obtained through increasing the clock speed.
I'm not saying my parent poster is wrong, but I sure as heck can't imagine the physics behind his statement. So if I'm wrong, someone please enlighten me.
I can see dual cores offering a smoother user experience -- one core could be handling an audio stream while the other is doing phone crap. I don't see how it could improve battery life though....
The theory is that two cores can accomplish the same thing as a single core while only working half as hard, I've seen several articles stating that dual cores will help battery life. Whether that is true I don't know.
Sent from my T-Mobile G2 using XDA App
Kokuyo, while you do have a point about dual cores being overkill in a phone I remember long ago people saying "why would you ever need 2gb of RAM in a PC" or "who could ever fill up a 1tb hard drive."
Thing is wouldnt the apps themselves have to be made to take advantage of dual cores as well?
JBunch1228; The short-term answer is nothing. Same answer as the average joe asking what he needs a quad-core in his desktop for. Right now it seems as much a sales gimmick as anything else, since the only Android ver that can actually make use of it is HC. Kinda like the 4G bandwagon everyone jumped on, all marketing right now.
Personally, I;d like to se what happens with the paradigm the Atrix is bringing out in a year or so. Put linux on a decent sized SSD for the laptop component, and use the handset for processing and communications exclusivley, rather than try and use the 'laptop dock' as nothing more than an external keyboard
As far as battery life, I can see how dual-cores could affect it positively, as a dual core doesnt pull as much power as two individual cores, and, if the chip is running for half as long as a single core would for the same operation, that would give you better batt life. Everyone keep in mind I said *if*. I don't see that happening before Q4, since the OS and apps need to be optimized for it.
My $.02 before depreciation.
Then there are the rumors of mobile quad-cores from Nvidia by Q4 as well. I'll keep my single core Vision, and see whats out there when my contract ends. We may have a whole new world.

Wow, that's complete nonsense.
You can't add parts and end up using less power.
Also, Android needs no additional work to support multiple cores. Android runs on the LINUX KERNEL, which is ***THE*** choice for multi-core/multi-processor supercomputers. Android applications run each in their own process, the linux kernel then takes over process swapping. Android applications also are *already* multi-threaded (unless the specific application developer was a total newb).

What's the connection? Just because the desktop processor manufacturers went multi-core and 64bit at roughly the same time doesn't mean that the two are even *slightly* related. Use of a 64bit OS on a phone certainly does ***NOT*** somehow require that the processor be multi-core.

The connection lies in the fact that this is technology we're talking about. It continually advances and does is at a rapid rate. No where in it did I say we'll make that jump 'at the same time'. Linux is not ***THE*** choice for multi-core computers, I use Sabayon but also Win7 seems to do just fine with multiple cores. Android doesn't utilize multi-core processors to their full potential and also uses a modified version of the linux kernel (which does fully support multi-core systems), that's whay I made the statement about merging. Being linux and being based on linux are not the same thing. Think of iOS or OSX - based on linux but tell me, how often do linux instuctions work for a Mac?
"you can't add parts and use less power", the car industry would like you clarify that, along with the computer industry. 10 years ago how much energy did electronics use? Was the speed and power vs. power consumption ratio better than it is today? No? I'll try to give an example that hopefully explains why consumes less power.
Pizza=data
People=processors
Time=heat and power consumption
1 person takes 20 minutes to eat 1 whole pizza while 4 people take only 5 minutes. That one person is going to have to work harder and longer in order to complete the same task as the 4 people. That will use more energy and generate much more heat. Heat, as we know, causes processors to become less efficient which means more energy is wasted at the higher clock cycles and less information processed per cycle.
It's not a very technical explanation of why a true multi-core system uses less power but it will have to do. Maybe ask NVidia too since they stated the Tegra processors are more power efficient.

You have come up with a whole lot of nonsense that has ABSOLUTELY NO relation to multiple cores.
Energy consumption is related to CPU TIME.
You take a program that takes 10 minutes of CPU time to execute on a single-core 3GHz processor, split it between TWO otherwise identical cores operating at the SAME FREQUENCY, add in some overhead to split it between two cores, and you have 6 minutes of CPU time on TWO cores, which is 20% *MORE* energy consumed on a dual-core processor.
And you want to know what NVIDIA will say about their bloatchips? It uses less power than *THEIR* older hardware because it has **SMALLER TRANSISTORS** that require less energy.

I was comparing speeds on the Atrix compared to the [email protected] and they matched. The Atrix was much more efficient on heat and probably with battery. The dual cores will use less power because the two cores will be better optimized for splitting the tasks and will use half the power running the same process as the single core because the single core runs at the same voltages for a single core compared to splitting it between two. Let's not start a flame war and make personal attacks on people

It is disturbing that there are people out there who can't understand this VERY BASIC engineering.
Voltage, by itself, has NO MEANING. You are forgetting about CURRENT. POWER = CURRENT x VOLTAGE.
Battery drain is DIRECTLY PROPORTIONAL to POWER. Not voltage. Double the voltage and half the current, power remains the same.
Dual core does NOT increase battery life. It increases PERFORMANCE by ***DOUBLING*** the physical processing units.
Battery life is increased through MINIATURIZATION and SIMPLIFICATION, which becomes *EXTREMELY* important as you increase the number of physical processing units.
It is the epitome of IGNORANCE to assume that there is some relation when there is not. The use of multiple cores relates to hard physical limitations of the silicon. You can't run the silicon at 18 GHz! Instead of racing for higher frequencies, the new competition is about how much work you can do with the SAME frequency, and the ***EASIEST*** way to do this is to bolt on more cores!
For arguments sake, take a look at a couple of processors;
Athlon II X2 240e / C3.... 45 watt TDP, 45 nm
Athlon II X4 630 / C3.... 95 watt TDP, 45 nm
Same stepping, same frequency (2.8 GHz), same voltage, same size, and the one with twice the cores eats more than twice the power. Wow, imagine that!
The X4 is, of course, FASTER, but not by double.
Now lets look at another pair of processors;
Athlon 64 X2 3800+ / E6.... 89 watt TDP, 90 nm
Athlon II X2 270u / C3.... 25 watt TDP, 45 nm
Different stepping, SAME frequency (2.0 GHz), same number of cores, different voltage, different SIZE, WAY different power consumption. JUST LOOK how much more power the older chip eats!!! 3.56 times as much. Also note that other power management features exist on the C3 that didn't exist on the E6, so the difference in MINIMUM power consumption is much greater.
Conclusion: There is no correlation between a reduction in power consumption and an increase in the number of PPUs. More PPUs = more performance. Reduction in power consumption is related to size, voltage, and other characteristics.

Good job on being a douche. I didn't insult you in anything I said and if you disagree over my perspective then state it otherwise shut up. I didn't tell you english grammar isn't your forte so maybe you should keep your senile remarks to yourself.
You seem to want to argue over a few technicalities and I'll admit, I don't have a PhD in computer engineering but then again I doubt you do either. For the average person to begin to understand the inner-workings of a computer requires you to set aside the technical details and generalize everything. When they read about a Mac, they will see the word Unix which also happens to appear in things written about Linux and would inevitably make a connection about both being based off of the same thing (which they are). In that sense, I'm correct - you're wrong. The average person doesn't differentiate between 'is' and 'based off', most people take them in the same context.
So I may be wrong in some things when you get technical but when you're talking to the average person that thinks the higher the CPU core clock is = the better the processor, you end up being wrong because they won't give a damn about the FSB or anything else. Also, when you start flaming people and jumping them over insignificant things you come off as a complete douche. If I'm wrong on something then tactfully and politely correct me - don't try to act like excerebrose know-it-all. Let's not even mention completely going off track about about Windoze, servers aren't the only things that have multi-core processors.
I'm sure you'll try to multi-quote me with a slew of unintelligent looking, lame comebacks and corrections but in the end you'll just prove my point about the type of person you are. ****The End****

Generalizations lead to inaccuracies. You do not teach by generalizing, you teach by starting from the bottom and building a foundation of knowledge. Rene Descartes (aka Renatus Cartesius, as in Cartesian geometric system, as in the father of analytical geometry) said that the foundation of all knowledge is that doubting one's own existence is itself proof that there is someone to doubt it -- "Cogito Ergo Sum" -- "I think therefore I am". Everything must begin with this.
When they read about a Mac, they will see the word Unix which also happens to appear in things written about Linux and would inevitably make a connection about both being based off of the same thing (which they are).

So hopefully this train can be put back on the tracks...
From what I am understanding from more technical minded individuals, Dual Core should help with battery life because it requires less power to run the same things as single core. It can then probably be extrapolated that when pushed, Dual Core will be able to go well above and beyond its Single Core brethren in terms of processing power.
For now, it appears the only obvious benefit will be increased battery life and less drain on the processor due to overworking. Hopefully in the near future more CPU and GPU intensive processes are introduced to the market which will fully utilize the Dual Core's potential in the smartphone world. Thanks for all the insight.

fair enough, was not trying to drag it off-topic but just pointing out the battery life issue as a reason why they may be holding off in the adoption of duel-core and possibly quad core phones.
That's a yea and no. You'll see that the multiple cores gives the phone better battery life due to the fact that the processor can manage processes better giving it better battery. On the flip side, were not perfecting the processors. Were simply flying by through dual cores and quad cores. We were on single cores for about 6 months. Dual cores about 9 and then quad cores were developed. So the developers of these processors need to take more time to perfect the processors, in order to recieve better battery life, less hiccups, more consistency.

The new quad-core tablet, Asus Transformer Prime, has a battery life of 12 hours. This is because it actually has 5 cores. The 5th core is to update small applications with the tablet off so it doesn't have to power up the quad-core and waste battery power. There are probably other factors, but that is one of the main reasons why the battery life id really good on that tablet.

Can't really see why you would want to overclock the One X, the phone is blazing fast anyway, 4 cores at 1.5 is enough..
But like everybody else said, the phone would probably burn up..
I wouldnt overclock my device - at least not at the stage we reached now.
Why?
a) As long as there is no way to lower the voltage this might toast your device - its a unibody, keep that in mind!
b) 100 MHZ more would have literally no effect - its a 6 GHZ device, even if you boost it up to 6,4 - you wont notice, it will just drain your battery.
6 GHZ is WAY enough...this is smartphone...I mean...seriously...its got more power than my 4 years old 1K €uro notebook...

I wouldnt overclock my device - at least not at the stage we reached now.
Why?
a) As long as there is no way to lower the voltage this might toast your device - its a unibody, keep that in mind!
b) 100 MHZ more would have literally no effect - its a 6 GHZ device, even if you boost it up to 6,4 - you wont notice, it will just drain your battery.

well first of all you can't just multiply the frequency by the number of cores. I'd much prefer an actual 6Ghz single core processor over 4x1.5Ghz because it won't have any compatibility and efficiency issues. Assuming they are of the same architecture and power usage of course.
Also the ARM low power SOCs probably don't have comparable number of commands per clock cycle as an x86 high performance CPU, even if it's 4 years old.

i agree.. when the multi-core CPUs first came out intel said doubling the core number would give as 47% boost in total performance (not x2 like apple says as they do not know it) lets assume that to be %50 to make the math a little bit easier..
so basically we can make the math here as; 4 cores at 1.2Ghz (when the all 4 active the clock is 1.2Ghz) gives us 1.2 x 3/2 x 3/2= 2.7 Ghz single core performance.. this value for SGS3 is; 1.4 x 3/2 x 3/2= 3.15Ghz
and here we can say dual core at (X) Ghz gives us (X) x 3/2=2.7 thus the (X) = 1.8 Ghz.. so, if you overclock any arm9 based Dual CPU to 1.8 Ghz you get the same performance "on paper".. if you want to catch up with SGS3 we need to OC it to 2.1 Ghz which is impossible at the moment i guess..
what makes the difference here is the lower loads or multiple loads on the CPU.. corecontrol users probably would have noticed; sometimes when the all 4 core are active the clock is only 480 or 640 Mhz (even 320 sometimes if i remember correctly) .. the same amount of load could be taken care of by a dual core at about 720 or 960Mhz.. but here the quad core system stays cooler with a little less energy consumed (or wasted) (as long as all the cores are in one uni-body structure, putting 2 or 4 single cores phsically together is not the case for our smartphones) this is how apple made sure about the smoothness of the ipad 2, new ipad and the iphone 4s.. they used lower clocked 2 power vr 543 GPUs.. when the load is little they can clock down to very low speeds and share the load..
and also you can always find an emtpy core waiting for new task when the others are busy..
so, long story for short; if we were dealing with a little amount but hard processes, having a single core at 2.7Ghz would be good since the quad core design would not cut one task into 4 pieces... as long as we were not thinking about the battery life and the heat.. but since we are dealing with lots of tasks which all could be handled by 1.2Ghz power having 4 cores is better for battery saving and having an empty core for a new task to run parallel with the other running tasks in the background..
It is OC out of the box I think Nvidia OC them for us and it's already pushing itself at the very edge of what is possible for it to do based on temperature, I seem to remember Hamdir saying something along those lines once upon a time...
Why bother to OC it's fast enough as it is.
---EDIT---
hamdir said:
only faux kernel betas allow OC
big warning OC is bad for the HOX given the thermal envelope
you are risking both you battery and processor if you OC
i know you are used to OC from other devices but those had headroom, it is not the case this time, T3 is operating at its max thermal capabilities on the HOX

the snapdragon 2 on the Arc had a lot of headroom
the chipset is rated @ 1.5ghz stable!
not the case with T3 its milking the very maximum of the 40nm process
in other words Nvidia is OCing its T3 out of box because their chips are designed to survive massive amount of heat (sadly it doesnt mean the battery or other components would survive)
it is already Overclocked lol
sometimes you have to listen to the "science" of it and surrender

Hello,
I recently got my Galaxy tab S 8.4 LTE with Exynos. However I have some questions. Sometimes i felt a little bit laggy. Is it normal? Also when I use CPU-Z i only see 4 cores instead of 8. -I am sure it is exynos version- Should not this device run all the cores simultaneously?
And i also would like to ask if there is a way to increase the devices overall performance.
Thanks.

Touchwiz can be a little laggy. You can root your device and freeze or delete a lot of the bloatware. Mines very snappy. Don't experience any lag. I'm still running stock Touchwiz, I just froze all of the bloat which keeps it from starting or running in the background. Also you can flash a custom rom. There's some really good ones available at the moment. Blisspop makes a excellent rom. It would completely get rid of Touchwiz all together.
Exynos is a octacore. However in this tablet it only runs 4 cores at a time. The 1.3 ghz quad core processor runs when your not doing intensive things. So let's say like, browsing the web or watching youtube, checking your mail, etc etc. It uses those to save battery life. Now when more intensive tasks are going on it switches to the 1.9 ghz quad core processor. It's not a true octacore as it only runs 4 cores at a time. However I believe it was the note 3 that had this same processor and there was something called HMP. It allowed the processors to run all 8 cores at once. But us galaxy tab owners do not have that. I don't know if that's something that can be released for this tablet from Samsung. But as of now the device runs on 4 cores at a time and switches back and forth depending on the tasks that are being done.

Interestingly, I haven't had any problems with "lag" with either the stock GUI or because of the background processes.
I must say that despite using the fancy shmancy octo-core battery saving wizardry, my Tab S falls flat on its face with regards to battery savings. In can probably play HD video for 10 hours straight on a full charge, but I don't know if the device could do 5 hours of web browsing if you visit truly bloated modern web sites, like the kinja blogs. I personally suspect that video and other multimedia are run in power saving mode on the slower cores, but web browsing probably calls for the faster cores in many cases. I am thinking it would be cool of there was a way to force everything to run on the slower cores all the time. When I am out in a library or coffee shop without a charging cable, I would have accepted a slower performance in exchange for a long battery life.
Understood. However i am not sure if things go like that. I mean I open CPU-Z and monitor cpu usage. It is not even stable it goes up to 1600 mhz sometimes even though i just monitor it. I wonder if there is a way to monitor my CPU usage with a background APP so i can see if it is overloaded even with simple tasks such as facebook.

If you're rooted you can use an app such as setcpu to modify cpu settings.
If all it does is switch between 2 quad core chips that has to be the dumbest thing I've heard of. What's the point if it can just step the fast one down in frequency and voltage?

Supposedly more efficient with current technology at time of release.
The new 5433 (such as my Note Edge) has true HMP Octa-core processor. So SWEET
