How can i check if my phone is using dual core?? I tryed to use benchmark after update to V10c and i think its a little slow, when i start to download/intall an app i get some lag while changing screens.
Running Quadrant Standard, in system information it shows me:
CPU: ArmV7
Cores: 1
Hardware: Tegra 2
Not sure, but from what I've read Quadrant isn't dual core optimized yet, so it won't probably show both cores. Try Neocore instead, it uses both cores.

Not quadrant, android, since only 3.x is optimized for honeycomb... I believe that 2.4 ice cream will have total multicore support

I'm pretty sure Android is using both cores... it just needs to run programs that take advantage of it...
I'm not saying android is not using both cores, it is, I'm saying its not optimized for, yes there are applications where dual cores/multi thread is enabled and optimized but the OS it self is not.

Just did cat /proc/cpuinfo and I see only one cpu is it normal? On a pc a core is shown as a cpu.
I also did cat /proc/version and I see it says SMP but maybe it is not really compiled with SMP support?
That's correct. It's 1 CPU with 2 logical cores.
Some of the apps don't recognize dual core chips yet. System Panel just received an update that recognizes dual core chip sets.

System Panel shows the dual cores nicely... but as said above, many apps don't recognize the dual core chips yet and do not utilize the power.
On top of this, keep in mind that the Droid 3 turns off its second core when the CPU load is low to preserve power, so unless the OS is being taxed, the second core won't show even if the app supports it.

This would explain why system panel shadows out the seconds core at times, I want aware of why it was happening.

/proc/stat and /proc/cpuinfo will only show the second core on a Droid3 when it's online. To determine the number of cores I'd recommend sysfs, specifically /sys/devices/system/cpu/present. The Java method Runtime.availableProcessors() also only returns the number of online processors, so you'll get a value of 1 when the second core is sleeping on a Droid3.
Search for "sysfs-devices-system-cpu" on google for a description of the /sys/devices/system/cpu/ data. I'd post a link to kernel.org but the forum is concerned I'm a bit of a noob and might be into spamming. Apparently I'll have to wait a few more posts before I can tell you all how I bought my Droid3 for $50 after spending $3,000 in penny bids for it.
Penny bids? Where u bought ur droid
For $50?

The penny bids thing was a lame attempt at humor...this site doesn't permit posting links until you have 8 posts...largely because scam sites such as those "penny auction" things will otherwise spam the heck out of them.

IS THERE SUCH THING AS TOO MUCH CORE FOR A SMARTPHONE?

I see no difference between single core and dual core services except in gaming.I'm quite content with my single core device compared to a dual core
Sent from my inter galactic super fantastic communication device.
Honestly, I'm a little torn on this one. The spec snob in me says "Moar cores, moar better, moar faster! Gimme nao!!"
However, I own both the HTC One X (international Quad core Tegra 3 variant) and the Samsung Galaxy S III (TMOUS S4 dual core variant)
They are both fast, powerful phones....
(disclaimer: yes, I know the S4 is based on a newer architecture (28nm vs the 40nm Tegra 3)

I don't know. It still takes about 3 full minutes for a picture to show up in the folder I moved it to. Maybe that's not the phone messing up, but I wonder if it would happen faster with a quad core phone.
BUT, I am inclined to agree with Greg Sullivan as a gut instinct.

guys thats a simple a thing.
the performance isnt based on the number of cores,you can have a phone with dualcore cpu and it can be better(in performance) than a quadcore one,but you can have a quadcore which is better than a dualcore phone, its based on the software and the other hardware,its not only about cores.....
Eventually more cores will make a difference, but it's still too early right now
Once the majority of software is threaded, then more cores will mean faster processing and better battery life, especially in a multi-tasking environment like Android
But for right now, I wish there was as much attention paid to ram speed and r/w speed to internal/external sd storage
That would be a bigger boost to performance right now than cramming a 20 core cpu into a phone
Of course there can be too many cores. Every core more, than needed to complete a given task in an appropriate amount of time is one core to much. The question is, what will the average user (not people like us) do with their phones, and how much processor power does that need. The average users I know use their phones for Facebook and Angry Birds. Not very demanding things. To be honest, I don't do very much more CPU-intensive things, too.
Also, don't forget that software has to be optimised to run on multicore-machines. And those software that can be highly optimised, takes more advantage of GPUs than of CPUs. And highly parallelizable tasks are usually there to calculate things that you don't want to bother with on your way.
It's a matter of how people use their phones, but as a guideline we can take Intel's and AMD's x86-processors, for most tasks dual-core is enough, and more than quad-core is rarely used at all for private purposes.

The amount of cores is not the only factor for performance.
However, assuming all other factors are the same, more cores will yield better performance in multi threaded code.

I'm surprised no one has brought up the PS3 yet. It's processor is the epitome of this discussion.
More cores can make a huge difference, but the process is difficult and sometimes not with it, especially if they're unused.

Well the Cell Processor isn't like traditional multi core processors.
Each of the helper cores can only do single floats, but they are good for assisting the Gpu.
(I think it has been super fast bus between the cpu and gpu)
A very unique architecture, which is why it took several years to fully take advantage of it.

The PS3 doesn't have to last off of a limited power supply. They can throw as many cores as they want in something with a wired power supply, when you switch over to something like a cellphone that has an expected battery life all that crap flies out the window. If the cores aren't being properly utilized that's just wasted power (at least to me). I am going to hold onto my Nexus S until it either dies out or stops being developed for. Hopefully multi core processors are better utilized by then.
wouldn't it be possible to break 1 chip into like 10 smaller cores, so it's almost like an army tackling the date transfer rather then 1 big chip tackling the data transfer? I know that that they're integrating GPU's with CPU's now, but what if they were to make 5 small GPU cores and 5 small CPU cores inside of one blazing fast chip. could it work?

Well they have to make them smaller.
If they kept the build process at the same size and made them more powerful, they would be giant, use a ton of power, and generate a ton of heat.

I don't think more cores will be added to phones for a long while yet anyway.
This is because we had single cores and dual cores for years and they still work perfectly well.
Proof of that is the S2. It's an old phone in comparison to the newest phones on the market, yet it's still more powerful than the majority of phones around. Now, I know that it isn't purely based on the cores, but they are a deciding factor.
The dual cores of it can still more than easily do everything that is required of them, without even struggling.
So based on that, quad cores aren't even essential as of yet, so it's going to be a long time before more are needed.
I'm a product of the system I was born to destroy!
From a developer’s point of view, to get any advantage out of multiple core processors can involve a complete rewrite of the application. Is it worth the pain of doing this? The job has to be able to be split into threads that can be run completely independently of each other. In some cases this is impossible, or hardly worth the effort for any advantage returned.
On a PC, I have written a few number crunching programs that can farm out parcels of work across all four cores, using the _beginthreadex() Windows API. It still has to wait for the longest running thread to finish before it can carry on, meanwhile the other cores that have finished, sit there idle.
While multicore devices can run different applications at once, can you keep up with them all? There is only one human interface to the device.
There is very little software that really knows how to make full use of multiple cores.
Hello everyone
I've been reading for a few days in this forum about the Motorola Razr i
I certainly found interesting articles but strangely I have found that very few refer to the Intel chip
just as I have been looking about the chip of "Motorola Razr i" and found a curious comment
"Medfield z2460 was meant to test the waters and is the reason why it was launched in india and not the US. Just a precursor to the medfield z2580. The z2580 and Clovertrail will be offered in dual core variants (not to mention quad core for clover trail) and will ditch the imagination technologies sgx 540 for an sgx 544 mp2 which runs 34 [email protected] mhz.
The sgx 540 gets 6.4 gfllops @400mhz . The adreno 225 runs at 24.5 [email protected] 400mhz and the tegra 3 (t30l or t33) gpu runs 13 [email protected] mhz. So being that 6.4gflops vs 24.5gflops is relative to 202% what do you think happens with 34 gflops vs 24.5 gflops? Plus the s4 is 103 mflops single threaded while medfield z2460 is 90 mflops single threaded on the cpu side. That's pretty close. Dual core comparison with sgx544 might actually be superior and at a higher process node (32nm vs 28nm), and that's with an in order instruction set vs ARM's out of order. I don't see how you get "x86 Atom has very slim chances when taking on Qualcomm’s ARM processors or any other new generation ARM mobile CPU from Samsung or Nvidia" with that info. Your talking a gpu and a core.
Come spring they go out of order, not to mention ditching 5 year old architecture for silvermont, 22nm process and inclusion of intel hd gpu with 40 to 80 gflops (depending on eu count) and you think there will be no competition? Even the apq8064 adreno 320 only has approx 40-45 gflops but that doesn't include the modem so higher tdp .
Maybe the exynos 5250 with mali [email protected] 68 gflops will be a threat given release schedule but still, nearly matching single threaded performance with the best chip on the market (and with 5 year old architecture), and beating every ARM chip to date in java script for a first try/test the waters offering? Swap a gpu and add a core and its game on. And adding new architecture, 22nm, out of order instruction and hd graphics and ARM might have a problem until 64 bit ARM v8."

My question is How true is this?
not publish the link to the site because I do not know if this is right in this forum.
I apologize for possible flaws in my English.
I'm having a super-smooth experience, so yeah, the hyper-threaded single-core chip is doing a very fine job compared to the ARM competitors.
But is it true that Intel will go out-of-order for their next architecture? Because the whole point behind Atom processors was to take advantage of Intel's advanced lithography and well tought architecture, then simplify it to make it consume much less energy (and go from out-of-order to in-order was one of those simplifications).
Well I always thought Intel smartphone chips were more powerful CPU wise but gpu wise its behind.
And christ you can quote all the figures you like but it doesn't mean it'll actually reach that. Its what the individual parts can achieve.
Put them into a phone and reduce the power consumption to an acceptable level = a lot less than quoted figures

How many cores (not cpu) does a htc one have? It's has 4 cpus I know that, so what about the gpu? And the HTC one has an image processor, so does that make it 6 cores. Like the Moto x has 8 cores. 2 cpus, 4 gpus, 1 natural language processor and 1 contextual computing processor. So can you tell me from this explanation how many cores a HTC one actually has
