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?

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.

Amazing gpu? The Galaxy S I opposed the iPhone 4. The Epic 4G has a better gpu than the iPhone 4, the PowerVR SGX 540 vs the iPhone's PowerVR SGX 535. Just thought I'd mention it since you're in an Epic 4G forum.

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.

2 A15s > 4 A9s.
Also, the A15 use less power. I'd take the 2 GBs of RAM with the newest CPU anyday.

You don't have any lag on our epic 4g's? What ROM are you running? I've tried every rom out there and am friends with several other rooted epic owners, none of our phones are remotely comparable to the modern phones like s2 and above.
I'd love to see a video of you opening and running netflix, facebook, web browsing on chrome and stock, or whatever if you have time because this blows my mind. i'm doing something horribly wrong.

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.

[Q] Tegra 3 vs Exynos 5

The Nexus 7 has a quad-core tegra 3 with 4 cortex a-9 cores while the Nexus 10 comes with a dual-core exynos 5 with 2 cortex a-15 cores. So which chipset is more powerful? Cortex a-9 is less powerful than the a-15, but there are twice as many cores, and it kind of confuses me why Google would go with a quad-core for their tab, but dual-core for their full-sized tablet. Thanks for the answers, I don't know whether I should keep my nexus 7 or trade it in and buy a nexus 10 when it's released.

The a15 dual core murders our tegra 3.

The Dual Core Exynos is "better". But they are two completely different products with completely different functions. So just because the N10 has better hardware doesn't tell the whole story.

Note 2 and Beyond: Exynos 5 (big.little) Octa-Core

What do you all think?
CES: Samsung unveils an eight-core Exynos 5 smartphone chip
Hints at a superfast Samsung Galaxy S4 / Note 3
LAS VEGAS: KOREAN HARDWARE MAKER Samsung unveiled its eight-core Octa Exynos 5 processor at CES on Wednesday, which is likely to feature in its Galaxy S4 smartphone.
Making up for its lack of high profile announcements at this year's Las Vegas consumer electronics show today, Samsung unwrapped the eight-core chip designed for use in smartphones and tablets.
Samsung said that the Octa Exynos 5 chip is much faster than its previous processors including the Exynos 4, and boasts much lower power consumption. That's because the chip is split into two sets of quad-core processors that both use ARM's new Big.little processor technology, pairing an energy efficient ARM Cortex A7 chip with a more powerful Cortex A15 multicore chip.
According to Samsung, the chip is faster than its Exynos 5 dual-core chip that features in the Google Nexus 10 - presently the fastest Android handset available on the market today, and claims it will bring a new level of processing power to mobile devices. It said that this chip will also bring a much more impressive gaming experience to its next generation mobile products, and will easily handle HD media streaming.
That's not to say your next Samsung smartphone will have poor battery life though, as Samsung claimed the eight-core processor is up to 70 percent more energy efficient than its previous Exynos chips.
There's no word yet on when Samsung's eight-core Exynos 5 processor will start shipping, but we'll be very surprised if it doesn't appear in the firm's next generation Galaxy flagship smartphone. We're likely to hear more at the Mobile World Congress show in Barcelona next month.

Android does not lag one bit on Nexus 4 running AOSP!
But this is actually a Dual-Quad core with a powerful Quad Core Cortex A15 combined with Quad Core Battery efficient Cortex A7 and the cores get switched in terms of workload so it can save battery more that normal Quad Core processors.

Don't be sure.
It has 4 low-power Cortex A7 cores to handle easy missions and save battery. Especially when screen is off.
Check out Tegra 3, only the 5th core is working when screen is off, and the battery barely goes down!!

Yeah but. Too many CPU, GPU etc., you need to adapt appz for it, you have sooo powerful hardware and you still can't use it properly. And we have tons of appz like Seeder to reduce lagz lol.

for those who dont know, here are some of the interesting facts.
* The Octa-core CPU has 8 Cores, 4 A15 cores and 4 A7 cores
* The A15 cores are tuned to perform better by sacrificing battery life, and A7 core is tuned to be more efficient while sacrificing performance
* Even though the A7 is less powerful than A15, it is more powerful than the Cortex A8 cpu found in last generation phones. Still it uses almost 1/10 the power of Cortex A8
* Exynos 5 can operate in two modes. big.Little and big.LITTLE MP mode.
* In normal big.LITTLE mode, only 4 cores (or less) will be active at a time. The OS will not be aware of the Low power cores (just like in Tegra 3)
* In big.LITTLE MP mode, the OS knows that the CPU have 8 cores. It can use all 8 cores at once if there is demand for it. (My understanding is that android will not support this mode as of now)

People need to realise something.
Samsung could make a processor with 100 a15s for the gs4. It wouldn't effect the battery a bit unless the software was configured that way.
Almost everything on a processor is now power gated in the silicone, meaning it can be switched on off at will. A power gated section literally draws ZERO power.
So 100 cores would make no difference if only 2 of them were ever really used. It's just the amount of money Samsung want to spend on the silicone (smaller chips have higher yields since there's less chance of defects affecting the chip).
The die size (the amount of silicone used) for the A7 is tiny. Depending on how smart Samsung is (and how much coffee we can feed to devs like Gokan and AndreiLux ) , we could be looking at a powerful, highly efficient chip. Considering we're also looking at shrinking from 32nm to 28nm for this the A15s themselves might not even draw too much juice. Arm said A15s would be sensible for smart phone use at good 28nm or normal 22nm production. And Samsung production right now is very 'good'

Will note 3 and s4 feature this 8 core processor?

Most likely, yes. This was long over-due. The next big thing is probably already in development. If you have a Note 2 and you want to upgrade, wait for next year. The Note 2 is powerful enough and has excellent battery life, a very important factor to consider in today's mobile market.

All that power and no apps to utilize it. All those power and bad UI to go along with it. What wasted potential. Maybe in two year's time devs will start utilizing quad core processors and 16 cores will be the flagship standard. It's a shame Android is so fragmented.

[OFF Topic] A new architecture

8 cortex a7 are the same power comsuption than 4 cortex a8, the same or less that 4 a9, and less that 4 a15, and have more ghz in total, so it would be a good idea to make this, mtk make cortex a 7 processors and the 4 cores device with it are the same speed as google nexus 4, so i think that it will be a good idea

Which processor is/should be faster?

Hi I currently have an S3 i9300 and my company requires me to install MobileIron app and encrypt the whole phone; I find this slows down my phone considerably and often times I need to wait almost a minute for my app drawer to display my apps or some 20 seconds for camera to start.
Don't know if my experience with the S3 i9300 is only because of encryption app or also my processor-ram specs combination is not powerful enough to get a smooth experience.
So I'm looking to upgrade to an S4 but I don't know which version should I get based on which should be the faster one?
Should I get the 1.9GHz Qualcomm Snapdragon 600 quad-core processor or a 1.6GHz Exynos Octa-core processor?

Octa core variant is marginally faster but does not support 4g
Snapdragon Is little slow compare to Octa core but support 4g
u can choose as per ur need
Both are good device

the i9500 is faster even though it is really a quad core phone and only 4 cores can be activated at the same time. but I've seen somewhere that Samsung said with android 5 update the phone will be a real octa core and all eight cores can be used simultaneously.

The change to a i9500/9505 for you will be very good because the s3 I9300 only has 1gig of ram compared to the i9500/i9505 that have new processors and 2gigs of ram. That extra ram will definitely make a difference.

What are you saying, Android 5 doesn't even exist. Also the Exynos 5410 won't allow all 8 cores only the exynos 5420 can which is only in the Note 3

So based on what you said, I could even consider the Note3 which has 3gigs of ram and expect even better smoother performance? Saying I wouldn't mind the extra real state needs if I could realistically expect a noticeable improvement over currently described S3 conditions...

If u can go for the note 3 and u don't mind it's size ... go for the note 3 and never look back ... but i suggest u wait if you can ofc for about a month to see how the s800 against the 5420 exynos compares ... it not so much about the ram except if you are a really heavy multitasker but the cpu and gpu which we know for sure that in the snapdragon case it's a considerable improvement especially in the gpu department and we ve yet to see how the new exynos chipset will compare to it's older sibling ...
