Im thinking of a new phone but im perplexed. Should i get a dual core now like the Note or the Nexus or should i try and wait for a quad core? I dont usually game pn my phone, i have a Galaxy Tab for that.

people would tell you to get the quad, but personally I wouldn't cause
a : No app needs THAT much power yet, ( I might be wrong here. )
b : Battery life.

While I agree with the guys above, but I'm also in the same boat as the TC. I'm currently upgrade eligible and I've thought about buying a dual-core phone as I currently have an Aria but I think I've decided to wait until the Galaxy S3. If any of the rumors are true about it, it wont be out of date by my next upgrade.

The only "announced" quad cores are the huwai whatever its called(sorry dont remember the name of the phone). And the htc one x. Unfortunatly the htc will not have a quad core in america yet because the tegra3 is not lte compatable so i think we all gonna have to settle for dual core this year. I could be wrong but it seems like we wont get a quad for a while yet.

Luckily I just upgraded to the Samsung Glide in November but I know what you mean. Why go Dual core if you can get Quad core and be set for a good amount of time. The only thing I worry about quad core is will it eat up battery power?
My dual core is plenty and it doesn't even have dual core optimization ics OS yet... I can't think of any reason to need a quad core. It's like using a server to power notepad

What about Four+1?
What about 4-PLUS-1 technology? Any idea whether such systems actually make things run more efficiently using only 1 core (the "ninja" core) for low-end tasks? No idea about this, just floating it to see what news there is out there about this technology.
First of all based on ur bugdet
Second quad core rocks but if u don't need intensive processing with ur smartphone I would say go for the galaxy note its amazing

Dual core most people will tell you quadcore is faster than dual core this is false. Just because you have two more of something doesn't mean anything if you can not use it properly. This is why tegra 3 as you see gets beat by Qualcomm krait (dual core) and Ti omap 5 (dual core). Its not about how many cores its about efficiency. Nvidia pretty much doesn't know what they are doing still in the phone market.
Quad core on a phone is not required imo.
I would stick with a dual core (My Galaxy SII has never given me any trouble) - quad core is pricy and no real need for it at present. But you can always do a future investment since you will eventually want a quad core.
I am personally waiting till my quad core phones drop in price and are required.
The note does look sweet but my luck sprint wont get it and htc said the one x will be the fagship phone for this year

when android can fully utilize two cores, then we'll talk. Until then this is pointless. Quad core = less battery
Why no three cores?
I would like an upgrade as well lol, even if it means 1GHz Single core as I am currently surviving on 528MHz OC'ed to 692MHz (ofc single core) lol
It can handle everyday tasks all right but when you mention 3D games it dies (no gpu)

The thing is, the HTC One X in the UK can be brought for £28.50 a month - I would have to pay more than that for the Galaxy Nexus. Quad core phones are no more expensive to buy than dual core - phone manufacturers realise that at present, they simply don't have a market for constant £41 on free prices.
For the people who say quad core means less battery are wrong. Nvidia is still using
A9 architecture and 40 mn. Ti omap5, exynos (5, something), Krait, all beat tegra 3 quad core technology. Ti omap 5 and krait are using 28mn and exynos supposedly using 32mn. All of these processors are a15 which pretty much destroys nvidia a9 architecture. They also use less power voltage and completing the same task. Compared to tegra 3.
Quad core is pointless if you don't have the battery to back it up. The Razr Maxx has a 3,300mAh battery. That should have been available a long time ago. Companies keep designing phones with bigger screens, more powerful processors, and energy-draining 4G LTE. This is all fun and well, but the battery is the most important part and need to be worked on more.
In some cases dual core processors can actually be faster than processors with quad core.

Are there really that many things out there that can take advantage of a dual-core cpu? It seems to me that a decent cpu/gpu can go really far, but idk.
I'd imagine it'd be similar to a desktop. It will initially help with general smoothness of the user experience. Eventually apps will catch up with the hardware and be multithreaded.

More cores = better efficiency = longer battery life. It's not all about performance.
On any os aside from android, no.
Currently no. Seeing as software has yet to catch up to hardware, and really never has in this technological era. >.>
So with such info, one can make the statement to say the latest hardware is never needed, atleast in its time. Sooo... lets all throw away our core i7's, 1080p displays, Radeon HD 6990, and go back to the good ol' pentium 4 with integrated Intel graphics.
the new android os (ice cream sandwich) is supposed to support dual-core processors. If this does end up happening, it won't be long till there are apps such that do make use of the dual-core as well.

All depends on the software taking advantage of dual-core or not.
Similar scenario happened on desktop PC few years ago, and dual core cpu performed worse than similar clocked single core cpus when running non-optimized software. Took a period of time for the software to take up.
This is a hardware question, I have a friend who owns a Desire HD, now he goes on and on about how Single core phones are just as powerful as Dual core phones because, and this is his theory, a Dual core phone that says it is clocked at 1 GHz actually has either core clocked at 500 MHz, whereas the core in a Single core phone is clocked at 1 Ghz flat.
This just honestly seems like a frankly rubbish argument that doesn't make much sense to me, however I want to know if he's right, is there any literature out there that proves either way. Is he right? Or is he just being a boner?

long story short, he is wrong. keep in mind dual core s different from dual processor. the processor of a dual core simply allows 2 instructions to be carried out at onece adding performance to programs that have lots going on at the same time, but is still the same otherwise. They seriously help with multitasking so on android they would really help .

Correct! It allows 2 different "threads" to be computed at the same time. Your friend isn't all wrong though. Any app has to fully support dual threading. If it doesn't you will see the same performance from a 1ghz dual core phone and a 1ghz single core. Also remember the architecture of the CPU is important. In many cases a 1ghz phone may perform better than a 1.2ghz phone.
Sent from my MB865 using XDA
Well, almost.
Dual core means there are two independent processing units on the same chip. The chip itself operates at 1gigahertz, and that generally applies to anything on that die.
so your friend is wrong, as both cores run at 1 gig, but a lot more factors relate to actual performance.
In most cases, single core will not perform as well as a dual core at the same speed. (assuming they are the same arch)

Some dishonest Chinese sellers will do things like this.
Some places you'll see dual core NEC EV2 based tablets as "1ghz" even though it's two ~500mhz cores.
Other places you'll see a single core device deceitfully advertised as "dual core" as it includes a GPU in addition to the CPU.
They'll then add the GPU and CPU frequencies together and sell a 1.1ghz device as 1.5ghz.
(And don't get me started about seeing "Cortex A10" in the specs)
So long as we're discussing legitimate specifications, your friend is wrong
The most important thing is.... To tell your friend he is totally true.. When he revises his theory somedays later, then listen to him.

It really depends on the apps that you are running. Gingerbread does not fully support dual core processors but the Android (linux) kernel does. So if the apps you are running are written to take advantage of the extra core, they will run faster on a dual core phone. Where it does help to have an extra core is multitasking, with a dual core phone you will be able to smoothly run more apps at one time. But if you benchmark an app that only utilizes one core on both a single core and a dual core phone, the results will not automatically favor the dual core phone.
Yes I've used the search tool and the last post in the last Exynos 5250 thread was at december 2011 and I can't find any rules about reviving old threads so I don't want to fiddle with it since I might get an infraction or worse a ban and and the last Tegra 4 thread wasn't coherent enough for me.
I don't know all the details but I would like to start talking about the supposed new Exynos 5250 and Tegra 4 development so please bear with me, I need all of those who has reliable information to add in the discussion. I'd like to start things with how will it fare against this year's smartphones and tablets? specifically the Samsung Galaxy S3 (1.4 ghz Quad ARM Cortex-A9 + Exynos 4412 & 1.5 GHz dual-core Qualcomm Krait + Snapdragon S4 MSM8960) and HTC one X ( 1.5 GHz quad-core ARM Cortex-A9 + Nvidia Tegra 3 & 1.5 GHz dual-core Qualcomm Krait + Snapdragon S4 MSM8960) since they are currently the top Phones out there in the market performance wise.
Further into the topic will the new Exynos and Tegra make their predecessors completely obsolete once they come out? or is the performance leap going to be minimal at best? due to various factors perhaps you can't fully utilize their potential due to the limiting software apps out there? What I want you guys to elaborate for the community is how better will it be in terms of CPU and GPU benchmark performance. Please do share your Ideas and any reliable information about the said topic at hand.
P.S. I just got an SGS3 my very first smartphone and android, did I make a huge mistake by buying it or should have I gone for a cheaper Galaxy Nexus and waited for the new Exynos to come out?

what better than Nvidia Tegra 3
First off, let's talk processors:
Your phone, the SGS3 i9300 is packing the Quad-Core Exynos 4412, rather than the dual-core Snapdragon S4 (MSM8960) for North American versions of the SGS3. The international version of the HTC One X has the 1.5GHz Tegra 3 vs the North American version which has the S4 as well.
Performance wise, these processors are all pretty on-par. Benchmark scores are close, with the Tegra 3 gaining the upper hand graphics-wise with its 12-core GPU. The processor to look out out of these 3 would be the S4, considering it's the first processor to (kinda) take advantage of the A15 cortex.
...The reason I say kind of, is because there is some discussion on the S4 being a hybrid between the A9 cortex (Tegra 3, Exynos 4) and the beastly A15. Qualcomm is a rebel, and doesn't follow ARM's chip designs like the others do. But I digress...
A15 is going to be a HUGE improvement over A9. HUGE performance gains, higher resolution displays, USB 3.0,OpenGL ES 3.0 (depending on the GPU) and much much more. The dual-core Exynos 5250 is going to be based off the A15 cortex, and it's going to blow even the quad core A9's out of the water. Tegra 4 will almost definitely be based off A15 as well, and it's going to be a sight to see. As for the Snapragon S5, who knows? I'm sure Qualcomm has some cool stuff up it's sleeve.
To answer your question, yes the new Exynos and Tegra processors are going to make older generation processors obsolete, but that doesn't mean you made a bad choice. The SGS3 is a great phone, and as such has tons of developers making custom roms, kernals, and other fun hacks to keep you occupied for the months to come hack away!
hope that helped!
You didn't make a mistake as at present android is not able to push current quadcore devices to their limits and there is a scope for lot more improvement
So even though next gen processors will be lot more powerful, your phone will still be able to handle next android releases so Don't worry and enjoy your S3

Android already has full multi core support. The only thing holding back multi cores is the fact that many apps still don't make use of them.
Also, that other guy made some great points but forgot to mention S4 Pro, which we already know a good deal about and is very impressive. It sets the bar high for the next tegra and for exynos 5250.

They're not going to be "completely obsolete" (even GN and SG2, for example, are still good phones despite being "last year") but there is going to be a large performance increase to A15.
There's always a next big thing coming out, but generally it's not worth waiting for unless you're on the cusp. Even if the generation you shop is relatively old, the competitive market (unlike, say, that of a fruity company) helps to compensate you by providing discounts of the previous tech.
S3, in particular, is a darn good phone no matter how you look at it (except that it has hardware buttons, but I digress..)
Guys ive been reading on net bout android phone ive been wanting to buy sgs3 but when I saw some forum saying quadcore is useless on sgs3 that its better having dual core and now I saw Xperia tx verion that won benchmark test that saying has better performance that sgs3 so guys what is the phone?
For me im into gaming RPG on android phone and net surfing music etc
I'm pretty sure only the international sgs3 has a quad core... but I may be wrong on that.
As far as cpu performance goes, I prefer the tegra processors over the snapdragons. LG optimus hd has one of these in a quad core version available oversees.
This isnt about opinions though, trust the benchmark results.

Eh same could've been said about dual core when it first popped up for us. Its more about taking advantage of the cores that's the situation. Later versions of android are surely to take full capacity of the cores as more and more phones adopt. As for the phone, the gs3 is perfect for gaming, media, browsing ect. Although its plastic, the way its shipped makes it comfortable to hold in the hand

The best overall performance for a phone has to be the Galaxy S3. It comes with a Snapdragon S4, which is an entirely NEW architecture. That means snapdragon is half a generation ahead of the tegra 3 and exynos 4 in terms of cpu design. The only drawback of the S4 is its gpu, as it only has an adreno 225, which is a slight upgrade from it's old gpu. Otherwise the Galaxy S3 is still a powerhouse.
As for gaming, the Tegra 3 has a slight edge due to NVIDIA forming partnerships with game developers and they optimize some games to run well on the tegra 3.
http://androidandme.com/2012/05/sma...erformance-gpu-battery-life-and-web-browsing/
Overall, real-performance is the almost the same for both phones, One X and GSIII, but with a slight edge to the GSIII for its superior S4.
i think sgs3 dual core version with 2gb ram wont be released in europe i only saw in italy is quadcore with 1gb ram T_T but ithink 1g ram is still good coz my father has sgs2 ^^
so if we will base on experience sgs3 is still the best ill gonna save a bit more for that phone XD
Anything Krait is good, the S4 is a very capable chip. The quad pro version will be a beast.
Exynos is fast as well, Nvidia is better for gaming. But it also depends on how well the manufacturers optimise their software to run on the hardware.

Xperia TX. Go for it. No TouchWiz, better camera and design. Jelly Bean almost after launch.
it is very important to know if it is quad or dual cored. If it is quad then it will run faster because there is less stress on the cpu, then if it was dual. but, honestly, i ahve been using my droid incredible for a very long time. This is a 1 GHZ single core cpu and i use it heavily. i play n64 games on it without over clocking (the max cpu is like 1134 mhz, but i set it to about 600mhz and i can play with absolutely no lag.) so, what i am saying is that it doesn't matter if it is dual or quad cored because it is fast enough already. but, i know the international version, or at least the one i saw in india when i went there for vacation is quad. i think the USA version is quad as well. and btw, i have played with it. it's a great phone. the display is beautiful. the battery life is amazing. flash a kernel on it and i think you can run for 2-3 days with light/medium use in a single charge. go get that phone!
International galaxy s3 is quad core with 1gb a ram and is 1.4ghz which can be over clocked to 1.7ghz. I have an international galaxy s3 as I am from UK.

I am also looking at getting a new phone. I am leaning towards a quadcore because I tend to have phones for a while. (Still rocking my captivate...) I figure that even though applications are not optimized for the quadcore yet, they will be in the future, which means I can make use of the phone for longer without feeling the need that I "have" to upgrade.
Hello all!
Long time reader, first time poster! I had a quick question... regarding the new 1.5 dual-core processors in the new phones (SIII, RAZR HD, etc., or even the HTC Rezound) vs. the quad-core processors soon to release on the newer phones in the coming months. How much faster is the quad-core vs. the dual-core? Please don't respond with "twice as fast," I get that I was wondering if there would really be any noticeable difference in the speed capabilities of the phone, even when worked to it's limit.
For instance, 1 degree vs. 2 degrees temperature - it's "twice as hot," but you're not going to notice it at all. But 40 degress vs. 80 degrees - "it's twice as hot" has a whole new meaning!
I am wanting to get a new RAZR MAXX HD, but was debating holding off for the LG Nexus or another quad-core phone that's on the horizon... Thanks in advance for all your help!
In Europe SIII has a quadcore too
Gesendet von meinem GT-I9300 mit Tapatalk 2
Personally I don't think it's noticeable at all. Maybe when browsing web, rendering goes faster in multi-core optimised browsers. And of course some games would run better. But I can't imagine any other use, unless you want to run SuperPI in the terminal there. It'll probably run nearly twice faster.
Edit: From the other point. There will be more and more optimisations in Android for multi-core SoCs, so quad-core will for sure "last longer".
Rebellos, thanks for the help! Not to open a whole can of worms, but what do you mean "run SuperPI"? Is this an app that I should be familiarizing myself with? (Fairly new to the ROMs, rooting, bootloaders side of things)
When I got my captivate, I had the option of waiting a month to get the atrix which had a dual core processor. I choose to go for the sure-fire "I Know it'll have dev support" single core processor and don't regret it.
This time however, there are like 3 quad core devices coming out. One x+ has a tegra 3, the Note 2 has an exynos. The Optimus G has an S4.
While dev support is still important.. the S4 is an incredibly compelling factor for me personally.

SuperPi is nothing more than a benchmark you really don't need to concern yourself with.
Remember when you are talking about cores, it is not simply the number of cores that you need to take into consideration but also the architecture which those new cores are built on. The new A15 Krait chips are dual core, but will blow the door off a quad core CPU with an older architecture. MHZ and Cores are relative. If they put out a modern super phone with a dual core processor you can bet those are two beefy and very fast cores.
There is the valid point that Android is going to continue to specialize in multithread execution but 1 core does not necessarily translate into 1 thread. A hyper-threaded cpu core actually shows up as 2 physical cores to the computer it serves, so if you are running a dual core that is hyper-threaded the PC thinks there is a quad core on board. It also depends on what type of application you are running as to whether a very solid 1 thread computational approach would be superior to a multi-threaded approach.
In short there is not set answer. There are hypothetical road maps defining architecture but these days innovation is so common said road maps could made an abrupt 180 if circumstances change. When if is time to buy a phone, or any computational device, consider what it's primary task is. That could help you decide whehter a multi or single threaded approach could be more effective. Ultimately as mentioned earlier everything is going the way of the multi-core, multi-thread, meaning instead of having 1 processor/thread complete 1 job, muliple processor/threads complete several mini jobs to arrive at the same point. Usually a multi threaded approach is more effective if designed correctly. Then look at what is available, where is your bang for the buck. Ultimately the number of cores and frequency run at has little to do with processing prowess. It's about design, innovation and engineering. Sorry if this didn't help much. It was more designed to give you something to thing about as apposed to pat, here you are, here's your answer as I rarely believe there is 1 approach or 1 answer to a solution. That's what computing is and computers = phones = innovation.
For gaming it makes a difference. For everything else, not really. Comparing the HTC One X vs the One XL (Tegra 3 Quad vs Snapdragon S4 Dual, respectively), the One XL benchmarks as faster than the One X CPU-wise (calculations), but the One X is more powerful graphically because the GeForce GPU inside the Tegra 3 chipset is more powerful than the Adreno 225 inside the Snapdragon S4. I have the Galaxy S3 i9300 while my girlfriend has the AT&T Snapdragon S4 Dual (LTE + 2GB RAM) version. Mine is clearly faster when it comes to heavy gaming, noticeably. Hers jerks on certain games like Beach Buggy Blitz, even on middle-level resolution, while mine runs completely smoothly on the highest resolution.
The only real comparison would be Snapdragon S4 Dual vs Snapdragon S4 Quad, or Exynos Dual vs Exynos Quad. The Galaxy S2 was as smooth as the S3, from personal experience (Sprint, Exynos version vs GS3 International Exynos version). Gaming was also super fast. But the Exynos quad is definitely more powerful.
TL;DR: It depends heavily on the chipsets being compared.
I have a T-Mobile Galaxy S2 running AOKP JB. In my opinion AOKP JB is A LOT faster than CM10. My phone is really fast now. Dual-core is still good.
gaming and browsing

True, but that's a completely different architecture. Exynos 4412 (the one in the i9300) is based on Cortex A9, whereas the Exynos 5520 is Cortex A15. It's like saying quad-core Pentium 3 vs dual-core Pentium 4. The Pentium 4 is a more advanced architecture, so it would win. It's like comparing apples to oranges.

For heavy games it makes difference.
In my opinion, a A15 based dual core may be a better as an overall proposition compared to a quad core A9. The A15 should have approximately 20%-40%+ better single threaded performance. Most of the time you are working in a single threaded mode.
In fact you only need quad core when using a very high multi-threaded load. Not very common on a phone.
If however the choice is between a dual core A15 vs a quad core A15, the choice becomes very straightforward. Get the quad-core in that case.
Dual Core A15 vs Quad Core A9 (of the same type of chipset, like Exynos 4412 Quad in the S3 vs Exynos 5520 in the Nexus 10/Samsung Chromebook), Dual wins. It's more efficient and just overall more powerful. The first A15 chipset are the Snapdragon S4 Pro (Quad only) and the Exynos 5250. It's speculated though that the Galaxy S4 will have an Exynos 5 Quad.

Actually its Exynos 5250 not 5520 and s4 pro is not based on A15 architecture its quite similar but A15(dual core) gives better performance than s4 pro(quad core) in single threaded operations ,but in multi threaded operations s4 pro is better,but with same number of cores on both ,A15(quad core) would be better than s4 pro(quad core) in both multi threaded and single threaded operations.
