my laptop is still dual core why the heck i need a quad core phone :D
[General Questions and Answers] sreza:
I'm sorry, but it won't. Look at the pc market for reference as to the use of multiple cores. Only very high-end gaming or graphical publishing, neither of which I would want to do on my phone.

Most programs can run on any core in a system, but 99% of them can only run on 1 core at a time. They are also unlikely to add multi-core processing to those apps, not only because the apps don't need that much processing power, but also because the vast majority of users aren't going to get a quad-core phone anytime soon.

"Why spend time and money developing a frivolous ability to multi-process an app that takes less than 1/4 a core's processing power in the first place to satisfy a very small minority of android users that won't see any visible difference anyway?" is the question all non-HD gaming developers on the Market are asking themselves as we speak.

The new dual cores are A15, versus Tegra 3 which is only A9. An A15 chip is 40% stronger at the same clock speed. Tegra 3's strongest core is clocked at 1.4, Krait S4's strongest core is 1.5.

1.5 vs 1.4 doesn't seem like much of a difference, but don't forget to adjust the numbers because Krait is A15! An A9 1.4 processor is what we were overclocking our Tegra 2 cores to at this time last year! Relativistically, consider it comparing a 1.4 core to a 2.1 core.

As far as I'm concerned, the only reason they have for making quad-core chips in the mobile market is to take advantage of those who fuel their self-esteem by the specs on their device (e-peen). And the sad thing is, The dual core A15's will outperform the quad-cores the vast majority of the time anyway!

tl,dr: 99% of developers won't make their apps multi-core capable, HD gaming is the only group that will. Therefore, your device will be faster and more efficient if you use a dual core A15 chip like the Krait S4 instead of the quad core Tegra 3 chip. Quad-core processing is not future-proofing. Future-proofing is to get a stronger chip, than just 1 with more weak cores.

I'd go for the Quad-Core by far.

It costs a bit more right now but you'll last a lot longer before having to buy a new phone. Android 5.0 will probably be optimized for quad-core. Imo it would be a bad choice to buy a dual-core right now!
[General Questions and Answers] Akiainavas:
It's always better if you have more power, and quad-core will give you that. Also 4 cores mean that you won't need an upgrade a bit longer.

But...

You won't actually use those 4 cores, and battery life will probably be worse.

It looks like this ( by 2x i don't mean 100% more, just "more" )

2x cost + 2x power + 2x future proof + battery life

vs.

cost + power + future proof + 2x battery life ( not always the case with battery )

You do the math.

[General Questions and Answers] jthatch12:
Coming from the view of an electrical engineer. There is literally no reason to have quad core! There are many other factors to consider when comparing the performance of CPUs, like the clock rate and width of the CPU's data bus, the latency of the memory, and the cache architecture.

EDIT: Side note, not until a few year ago did quad core processors come up for computers. Most laptops arw still dual core, mine has dual core 2.4 GHz processors and it runs MATLAB like a champ. :-)

I think that Quad is too much for a smartphone. The software should be improved, not optimized.
[General Questions and Answers] DPMAce:
Well I know the dual core android cpu is powerful because it can play games like dead space, and all the other gameloft games, etc.

Not sure how well a netbook could play those games. But on a netbook, I can edit all my word documents perfectly, and streaming my class lectures perfectly. I can't do this so well on my android tablet. Probably more software related than anything.

But my point is it would be nice to be able to do some real work on my tablet for a change. Especially if it has a quad core!!
[General Questions and Answers] xMoKax:
Dual core is just as good.

I read somewhere that the Galaxy S3 is going to have a Dual Core, but will be as good as a Quad-Core. Something about the Cortex A15 or something.
[General Questions and Answers] sreza:
Honestly... Every time someone says that buying a quad-core future-proofs your phone makes me want to do a -facepalm- the size of Texas....

Quad-cores have weak cores! Tegra 3 is an A9 where the strongest core is 1.4. In comparison, Krait S4 is an A15 where both cores are 1.5. In real life testing, Krait S4 gives twice the performance of Tegra 3.

99% of everything you do on your phone only needs 1 core. Developers won't bother to make their apps multi-core capable because it won't improve the performance at all! And even if Android 5.0 is optimized for multiple cores, only HD gaming will see any improvement from it.

It's like buying your grandmother a Ferrari. Quad-cores have all this "potential" that they're trying to convince you of so you go out and buy their product. But like your grandmother, who'll never try to push past 60 in her Ferrari, a mobile device simply won't see the use of a quad-core engine.

One possible exception. One single possible use of quad-cores in everyday phone use is battery power. Specifically, A fully optimized OS can split all workload between all the cores, dividing your battery consumption between them. So a single core device running at 100% uses 4 times the battery power of a quad-core device running at 25% on all cores. But Tegra 3 doesn't support this! Tegra 3 cores run all or nothing, it's just the way they're designed. Krait, on the other hand, has dynamic voltage, so they can actually do this to save battery power!

If I ever get a quad-core device, it will never be a Tegra core. The only possible situation where having a quad-core CPU on your phone makes actual sense, is if Krait makes a quad-core version of their flagship CPU.

This conversation should not be on the benefits of quad-core vs. dual-core. While informative, that conversation would have no real world benefit to those looking to buy a new phone. What is really relevant information however, is a comparison between the Krait S4 chip and the Tegra 3 chip. It does no good to make vague references to the "potential" of quad-core devices, without considering what it is we will actually have in our hands in the end.

You can brag all you want about how many cores you have in your Tegra 3 device, but it won't change the fact that my Padfone running Krait S4 will still run miles around it, no matter how much you try to "optimize" that poorly designed Tegra 3 chip. Four sedans will never be as fast as two Lamborghinis.

[General Questions and Answers] freezer2k:
I think it depends a lot on what you actually intend to do with your device, besides having a high benchmark score :)

I flashed ICS on my Motorola Defy yesterday, and it runs ok. Once the HW-acceleration is implemented 100%, i'm pretty sure it will run just fine for a lot of standard apps.

1GHz/512MB of RAM and a decent GPU go a long way imho.
[General Questions and Answers] anITee:
Not nesessary

I really don't think that the number of cores matters much. May the optimization of the operating system is more important.
[General Questions and Answers] Dark lord me:
Frankly my view is if you look at one Ghz with 510 ram devices they can still be pretty smooth it is all about how optimized they are. My phone has an OMAP 4460 and well it's smooth but nothing special. My tablet has a tegra 2 (ugh) that is just... no.

Nvidia well they usually are the first but they are so weak that as soon as a competitor comes out no one uses them any more.

I really look forward to seeing a large amount of S4 devices as well as the S5 and OMAP 5 devices, those will be extremely powerful and should be great on battery.

Vote for dual core for better Life time
[General Questions and Answers] freezer2k:
Yes,

I think we reached a point with smartphones (just like with PCs a few years ago) where more cores/MHz won't increase performance noticable for most standard apps.

And do you want to compile complex programs on your smartphone? I feel the urge to buy a new phone, just to have it. But if i think about it logically, it just seems like a waste of money, since i won't use the extra speed in 99% of my usage patterns.

Just to let you know engadget reviewed the htc one s and reviewed the htc one x. They said the htc one s battery life outlasted the one x. Also got better performance out the dual core krait than the tegra 3 quadcore version.
[General Questions and Answers] tjtj4444:
Just as expected. I hope this gets more attention, we need more powerful cores (per GHz), not more cores!!

It is different on PC's, where a modern CPU core is more or less so powerful it can be, so increasing number of cores is the best thing to do. But we're far away from such powerful cores on smartphones.

-facepalm- Why don't people ever bother reading before posting?

I'll say it again, and if anyone needs more details look up my other posts.

In this current generation, dual-core Krait S4 outperforms Tegra 3 in every way.

Better battery life, faster speeds, dynamic voltage, A15 vs A9, more future-proof!

Please, learn about the science behind these chips and consider the current software environment before airing your ignorance for all to see. In principle, with all other factors being the same, and in an environment not hostile to multiple cores, then and only then is a quad-core phone viable.

Until such a day comes, always go with the dual-core Krait or Exynos chipset. Because frankly, Tegra 3 was outdated the day it was released.

Many of you keep assuming that quad-core vs dual-core is essentially a trade-off between performance and battery life. This is not true. Dual-core Krait S4 has the edge in -both-.

There is literally no viable reason to prefer the Tegra 3 over the Krait S4, and thus, no reason to get a quad-core Tegra 3 over dual-core Krait S4.
[General Questions and Answers] DsturbD:
hopefully people will start reading your explanation which is spot on. could not agree more with you on this. you are exactly right

when the tegra 3 was announced there was only one game for it which was written by nvidia themselves to show off their shiny new processor...but right now that is probably THE ONLY app that uses a quad-core chip

you are not "future proofing" your phone by getting a quad-core chip. you are only wasting your money UNLESS you know that you will be using apps that are multi-core aware or that developers will be updating their apps to be multi-core aware, which right now, i am sure they aren't

After reading the Engadget reviews of the new HTC phones, looks like the US version of the HTC One X may be the way to go if you want to go with HTC. Best of both worlds with the bigger screen, LTE, bigger battery and the S4 dual core Krait. I might tell my wife to get that phone if it comes out on Sprint when her upgrade comes up on her Evo 4G.

Exactly. I'm more than happy with my single core Infuse. Screen size is more important to me than anything else. I'm not a gamer, and my phone is capable of doing a few things at once.

Just get what is right for you. If you don't need 30 things running at the same time, or are not a hard core gamer, I don't think it matters much. And besides, if you're a hard core gamer, why are you choosing a phone for that? Use a console or PC to get your fix.

Dont take this the wrong way, but have you read through this thread at all? I was all about tegra 3 until a few people made some really good points. We all assume more is better but apparently that is not the case beyween s4 and tegra3.
[General Questions and Answers] remat:
a quad-core cpu does not use more power than a dual-core because cores can be set in idle mode and do not use battery. on the other side a quad core is not faster than a dual core because an app can not run automatically on different cores. it has to be programmed for multi-cores (e.g. different threads for AI, gameplay, pyhsics).

A multi core system is faster in multitasking - different programs on different cores. Currently i'm on an ICS Costum ROM on my Desire and the new ICS Multitasking is working quite well. So i do not the the need in a quad core system.

But, as always - the bigger the better? Maybe its nice to tell your friends you've got a quad core proc. in your device :-)
[General Questions and Answers] sreza:
What you say is true only in the case where all individual cores on both chipsets are exactly identical. However, not all cores are built alike. See my thread on "The Myth of the Quad-Core Upgrade" for detailed information on why in this current lineup of smartphones it's better to go for the dual-core devices.
[General Questions and Answers] spyro2:
I have no idea why the 'cores' issue crops up again and again. Its the new version of the old MOAR MHz conversations of old.

If you have one core thats fast enough, your phone will be fast.

If you have 500 cores that arent up to the job, or an infinite number of ok-ish cores and a single-threaded CPU intensive process, your phone will be dog slow.

At the end of the day, decide what you want the phone to do. find a phone that does it as fast as YOU WANT IT TO for as little money as YOU WANT IT TO, and you wil be happy.

Buy your phone because it has moar cores than your mates or moar MHz, and you will either waste your money, or buy a phone you didnt want / like / need.
[General Questions and Answers] ks09h:
How big is the OP's ego?

If you want to be able to know you got the latest and greatest, then wait a few weeks for the quads to come out.

The quad cores will have better battery life, better graphics, more capabilities, probably better overall hardware, and will have the new Ice Cream OS if you go Android.

However, if money is an issue or you don't care about having the best available phone, then go with the dual core.

But either way you may want to wait until the quads come out because that will drive the dual-core prices into the dirt-cheap bargain bin.

Even on the desktop a lot of code is barely parallelized at all and I can't imagine it being any better on mobile. Having more than one core is neat as it prevents a single badly behaving application from choking the system, but more than that is probably just a waste with current software.

Looking a few years ahead, having lots of very power efficient cores might be neat for augmented reality -style stuff, though. Realtime image recognition that actually works, and all that.
