[Q] Samsung Galaxy S III - Nexus S Q&A, Help & Troubleshooting

The news broke that the samsung galaxy s iii will be arriving to all major us carriers in June. here is the article on the verge.
The official announcement confirms that it will launch with Qualcomm Snapdragon S4 1.5 GHz dual core CPU and 2GB of internal RAM vs the Exynos 4212(5250 need to verify which version they used) 1.4 GHz Quad-core and 1 GB of internal RAM
Can someone that knows what they are talking about tell me if there's a significant difference between the two specs I presented and which one will be faster vs battery consumption?
I am a T-Mobile customer, and looks like the SGSIII is said to come with HSPA+ with 42Mbps+, while the international version will be HSPA+ with 21Mbps+, on paper it is double the speed, what is the difference, is there sufficient coverage? I looked at the map for T-Mobile Data and they only show the strength of signal and don't differentiate the two.
so far here's the only real answer i've gotten on this topic?? anyone agrees?? disagrees? why?

The thing to realize about these processors, and most other processors available today, is that the s4 is based on the cortex a15 while the tegra 3 along with the new Samsung are based on the a9. The a15, at the same Hz and die size is 40% faster than the a9.
S4 = dual core Cortex A15 @ 1.5GHz - 28NM
Tegra3 = quad core Cortex A9 @ 1.5GHz - 40NM
Exynos 4(Samsung) = quad core Cortex A9 @ 1.5GHz - 32NM
S4 so far, in theory, is 40% faster per core, but having two less. Individual apps will run faster unless they utilize all four cores on the tegra3. Because the s4 has a smaller die size, it will consume less energy per core.
The actual technology behind these chips that the manufacturers come up with will also affect the performance output, but the general idea is there. Hope that helps to understand a little better how the two chips will differ in performance.

sorry if i'm posting in wrong section, I thought of posting it in the GSIII general forum, but only international versions available, I'll get biased answers, my guess is also the SII users at least recent ones won't be upgrading, and I know the HTC One users will just try to make it look like their phone is better. I need an unbiased opinion. lol

Samsung announces 1Ghz Cortex A8

1) http://www.engadget.com/2009/07/27/samsung-announces-worlds-fastest-cortex-a8-core-iphone-3gs-fro/
2) http://www.slashgear.com/samsung-1ghz-hummingbird-mobile-cpu-takes-on-snapdragon-2750348/
Yes, a 1Ghz Cortex A8. That is a core 400Mhz faster than what is available in the iPhone 3GS/Palm Pre and roughly 200Mhz faster than what is available in Omnia i8000.
Of course, many of you are probably wondering how this would compare to Snapdragon, but I can't really say I know. Problem is that benchmarks on phone CPUs are damn near non-existent and the few that do exists are really horrible. However, regardless of which you choose, performance will likely be very similar.
According to the article above, there is supposed to be one noticeable detail: The 1Ghz Cortex will supposedly be cheaper due to lower costs. So if this turns out true, then getting a phone with a 1Ghz Cortex will likely be cheaper.

Exactly how good is this Qualcomm Processor?

Seems with every smartphone that comes to the USA it gets some sort of Snapdragon Processor by Qualcomm and people do nothing but complain. So how does this Snapdragon S4 processor compare to every other dual-core processor out there and even the Tegra 3? Looked up some benchmarks and both seem to have their advantages and disadvantages. But what I really want to know is which one is better for real world performance, such as battery life, transitional effects, and launching apps. Couple people said Sense 4 is very smooth and "has LITTLE to no lag"? How does this processor display web pages in Chrome?
Read the thread "Those of your who are waiting too compare GSIII to HTC One X" in this forum. It only has about 6 pages but has a ton of information. Short answer is that the Qualcomm chip kicks serious ass.

yes and no, the tegra 3 does have a better gpu so in theory, better games. however, game makers cater to the mass. most androids that are active are mid-range, android 2.2 or 2.3, have a resolution of 480x800, and last years (or older) processors. although most will be made to work on the t3 and s4, it will be compatibility issues, not optimization. nvidia will have a couple games "t3 only" but even those will be made to work on other phones. now that ics is cleaning up some of the splintering of apps, we'll see some better options on both fields.
in short, yes the t3 is a better gaming chip. but for the battery life, games available, and current bugs i would suggest the s4. i may change my mind when the refreshs come out q3-4, we'll see.

Correct. However, most games are not optimized to utilize the Tegra to its fullest potential. That should change by the end of the year. The other point is that the S4 is just as good as the Tegra un terms of gaming performance. IMO, you should decide between these 2 processors by looking at the main area where the S4 truly has the advantage thus far, and that is battery life. So far, the battery life advantage goes to the S4. Just read the battery life threads in this forum and for the international X. It took a few updates to the Transformer Prime to start having pretty good battery life. The One X, will get better in that department with a couple more updates for battery optimization. The S4 starts with great battery life and will get even better in that department.

I say the snapdragon S4 is a better chip right now. The tegra 3 gpu is great and with the tegra zone games it really looks great. But he 4 cores CPU is really for heavy multitasking so you candivise the work between all four cores. They are A9 cores vs the custom qualcomm which is close to A15. It mans that for single threaded task and multi threaded task the snapdragon will whoop tegra 3' ass. Opening an app, scrolling through that app sect... also browser performance is slightly better on the qualcomm chip. Basically tegra 3 can do lots of things at the same time with decent speed vs the S4 chip which can do 1 or few more things at lighting speed.
The S4 is almost 2x faster than any other dual core out there. Anandtech did a few nice articles on the S4, including benchmarks vs tegra 3.
In real use, the S4 should be much better, because not all apps are multithreaded for 4 cores. The S4 completely kicks the Tegra 3's ass in singlethreaded benchmarks. I also expect the S4 to be better at power management, because it is made on 28nm node, instead of 40 nm, so its more compact and efficient.
About 23 I'd say

The difference in DMIP's is where the S4 really whomps on the T3. All the T3 has going for it at the moment is it's GPU. If you don't care about some additional gaming prowess, the S4 is the way to go.

Just to add to that and to be fair, S4 is at around 7000 at antutu benchmark while tegra 3 is at around 10000. I still prefer the S4
Eh...
It wins in 1 benchmark specifically enabled to take advantage of more than 2 cores. So if you want to play tegrazone games and have some basic lag, the T3 is for you. If you want to have a near flawless phone experience, and have decreased graphical performance in some wanna be console games, then the S4 is the way to go.
Actually you wont really notice the lack of graphics performance on the snapdragon s4. Its about 10% slower in most benchmarks but outperforms the tegra3 in a few as well. However i have a sensation xl with the adreno 205 which is only a quarter as fast as the adreno 225 and all games including deadspace, frontline, blood glory runs smoothly on it. To say the snapdragon s4 is inferior because of the slower Adreno 225 is really nit picking to me. For me bigger reason to choose one graphics chip over another is flash performance and this is where the exynos mali 400 kicks the adreno 225 in the balls. It handles 1080p youtube videos in browser without a hiccup while the 225 chokes even on 720p content.
Let me answer this. How good is it? More than good enough. Almost all apps and games are catered to weaker phones so the T3 and S4 are both more than good enough.
And my two cents, the S4 beats tegra 3

The S4 compared to the Tegra3 says it all. dualcore that beats a quadcore in almost everything.
Intel released the first native dual core processor in 2006 and shortly thereafter released a quad core which was basically two dual cores fused together (this is what current ARM quads are like).
That was 6 years ago and these days pretty much all new desktop computers come with quad cores while laptops mostly stick with dual. Laptops make up the biggest share of PC sales so for your everyday PC usage, you'll be more than comfortable with a dual core.
You really can't assume mobile SoCs will follow the same path, but it's definitely something to consider. I think dual core A15-based SoCs will still rule the day this year and next at the very least.
I was really on the fence about the X or the XL. But the S4 got me. Not having 32GB is already bugging me. But the efficiency (and my grandfathered unlimited data paired with Google Music) is definitely worth the sacrifice. Very happy so far! Streaming Slacker, while connected to my A2DP stereo, running GPS was great. I'm not a huge gamer though. I miss Super Mario Bros being the hottest thing!

correct me if im wrong but all 3 are A9 based including the S4. the first A15 will be the Exynos 5250, a dual core.

This is inaccurate.
The Exynos 4 and the Tegra 3 are based on the ARM A9 reference design.
The Qualcomm Snapdragon S4 is "roughly equivalent" to the A15, but not based on the A15. The same was true for Qualcomm's old S3 (which was equivalent to something between the A8 and A9 design)
One thing that most people don't realize is that Qualcomm is one of the very few companies that designs its own processors based on the ARM instruction set, and while S4's is similar to the A15 in terms of architecture, it's actually arguably better than the ARM reference design (e.g. asynchronous clocking of each core which is a better design than the big.LITTLE or +1 design).

Ultimate specs on neXus⁴. So what's the future like...

Quad core
2 GB RAM
4.7" Screen
1.5 GHZ Qualcomm S4 Processor
These are, IMHO, the most advanced specs in any phone (not considering Samsung cause I just hate it).
But even some of the most advanced phones out there don't have all in one. So what's it going to be like from here on...?
Also, do u think the competition is jealous of it? Namely the iDevices and the Lumias alike...?

Exynos 5 Octa and Snapdragon 800

Does anyone else think that the new-generation Exynos SoC will support 802.11ac and LTE-A? Or playing back 1080p video at 60 fps and 2k quality at 30 fps? These are features which were never really discussed about the chipset itself.
The Snapdragon 800 was confirmed to have compatibility and capability of all of the aforementioned. It sounds as if the Snapdragon 800 series will be the superior chipset, while the Exynos Octa will likely provide better power efficiency in some regard. It would be pretty disappointing if the Galaxy S IV got stuck with a Snapdragon 600 processor, given the date it's likely going to be pushed out on. It might make me consider the Note this time around.
i really hope all these rumors are fake, samsung should use Exynos on there flagship Galaxy S line ! if not the octa, maybe the Exynos 5 Quad Core 1.8-2.0GHz !
All the Snapdragon 600 happens to be is a mid-tear SoC, which improves upon the same GPU and performance of the S4 Pro. Real A15 architectures should blow this chipset out of the water. People seem to think that what they see now is good. But when the Snapdragon 800 and other A15-based chips start making their debut, this will feel dated quickly in the coming months.

clock-per-clock a15 is just 15% faster than krait, dont think that there's so much differences between the two.
they are both really solid performers and the batle is all on the maximum clock/power required rateo.
The SD800 will also feature Quick Charge 2.0, which is supposed to charge your battery 75% faster than other SoC chipsets without that same function. SD600 doesn't feature that either. I'm pretty sure if you seen the initial Tegra 4 benchmarks (based off of real A15 architecture) - they wipe the floor with the HTC One's SD600. Being 75% increased in performance over the Snapdragon S4 Pro (last year's best mobile SoC), the SD800 should bring comparatively the same or better results than the T4 mentioned. That's kind of going to be a disappointment if the S IV ends up with a SD600 and no Exynos 5 Quad/Octa, at least.

Octa core Exynos no better than snapdragon, so no more whining/boasting

http://www.engadget.com/2013/05/06/samsung-galaxy-s4-octacore-review/
The A15 in the octa-core isn't any better or worse than the krait in the snapdragon, either in performance or benchmarks. The extra four helper cores you get doesn't improve battery life. In fact, with the four a15 cores, it is actually WORSE than the more efficient krait cores. All those people bragging about how much the A15 is better than the krait based on thin air speculation really need to shove it up their butt.
It was already expected that the four extra low power cores in an octa core would not make much difference in battery life and actually be worse off than a regular quad-core processor. History has already shown with the Tegra 3's helper core that utilizing low power helper cores is a tricky and inefficient affair. It's not easy to switch between them, to prioritize when to use what, and instead of making a more efficient A15 design, Samsung relied too much on the chip's switching capabilities instead of making an overall better processor.
So if you want LTE, BETTER BATTERY LIFE, rom compatibility and dev support with the most widespread SoC, actual availability in stores everywhere, then stop waiting or worrying about the Exynos octa-core and pick the widely available snapdragon version of the S4. Anyone still spouting how great the octa-core version will be and still lies about it being EIGHT WHOLE CORES! when there's really only four are the biggest trolls in the S4 forum.

Heh, load of bullcrap.
If you do video battery tests you do them on Wi-Fi, congratulations on testing modem battery life. (Same carrier? Same tower? Same time of day? Bravo on apples vs oranges Engadget)
The benchmarks ARE faster on the 9500. Let's not mention that Engadget are incompetent fools who don't understand benchmarking. The Linpack scores are a joke as is CF-bench, one because the benchmark literally takes 0.3s and if you're idling before you press the start button that's not even though time for the CPU to ramp up to highest speed. CF-bench fails due to thermal throttling. At least that's a valid negative point, but not performance, scores are far beyond the 30k mark. I'm also getting funny more realistic results on the other benches: 661ms vs 732 SunSpider, 10% higher Vellamo score, 300 more 3D rating, and I'm sure there's others. Funny how they suddenly don't use GeekBench.
Matter of fact: the 9500 is undoubtedly faster and that's a technical reality. They even state so in their subjective comparison.
As for battery life: I've already mentioned how the early firmware is unfinished. I'm getting roughly 10% per hour usage; right now at 61% and 3h30 screen, and that's with doing benchmarks for the last half hour which ate 9%.
The only correct *video* battery life tests I've seen came from GSMArena (9505) and Russian mobile-review who got 12h.
You're going to have to wait for AnandTech to do a review in a few months to be able to use it as argumental material in such discussions.
Engadget is the pinnacle of ignorance and technical non-reporting, and as they've proved in their botched S3 review last year, the benchmarking seems to be done by the principal of their local baboon academy.

I don't think people thought that devices using Octa vs. S-600 wouldn't perform comparably. It would make no sense for Samsung not to optimize both to the best of their ability and S-600 is a powerful and efficient chip. You can't help but get the feeling that the s/w isn't "done" on either version based on comments on all the SGS4 forums about lag and display driver issues. That's echoed by some of AndreiLux's comments from looking at the code. Octa is literally the first public implementation of big.LITTLE. All of ARM’s future designs will be based on it. That means Qualcomm’s next generation of chips after S-800 will be based on it also as they license ARM’s designs. I'd expect over time that updates will continue to improve Octa's performance (power and efficiency) whereas S-600 is simply a massaged version of S4 Pro and the OEMs have a lot more experience working with it so there's less upside potential. I'd still buy the i9500 over the i9505 if I were going to get a SGS4 (I'm waiting for the N3) as I think its long-term potential is greater than S-600 and, going forward, I'd expect it to be used in more Samsung devices once Qualcomm's RF360 universal LTE baseband becomes available. Once that happens, unless there's production capacity issues, there no reason Octa wouldn't be Samsung go-to high-end chip. Just my opinion of course.
P.S. - The i9500 has about 250MB more free RAM (13%) than the i9505 as Adreno reserves 500MB for itself while PowerVR reserves a little over 200MB.

In any device even low end device you will not find the full ram visible as some is reserved exclusively of the system.
Also the post was on difference between Octa and Quall why would you expect a significant different as if that happens samsung would be trouble because they are the same device right S4 so samsung would tuned both in a way that the performance battery life is almost the same that hows it should be right you cannot say my s4 is slower then yours bec I purchased it from US ????

It really doesn't made a huge difference on Android devices. The extra memory just allows you to have more applications paused in the background before the kernel kills them to free up space. With the S3 if you're playing a game and switch to a web browser it's very likely that the game will be closed as it only has 1GB. On the S4 it will stay open in the background.

The A15 in the octa-core isn't any better or worse than the krait in the snapdragon, either in performance or benchmarks. The extra four helper cores you get doesn't improve battery life. In fact, with the four a15 cores, it is actually WORSE than the more efficient krait cores. All those people bragging about how much the A15 is better than the krait based on thin air speculation really need to shove it up their butt.
It was already expected that the four extra low power cores in an octa core would not make much difference in battery life and actually be worse off than a regular quad-core processor. History has already shown with the Tegra 3's helper core that utilizing low power helper cores is a tricky and inefficient affair. It's not easy to switch between them, to prioritize when to use what, and instead of making a more efficient A15 design, Samsung relied too much on the chip's switching capabilities instead of making an overall better processor.
So if you want LTE, BETTER BATTERY LIFE, rom compatibility and dev support with the most widespread SoC, actual availability in stores everywhere, then stop waiting or worrying about the Exynos octa-core and pick the widely available snapdragon version of the S4. Anyone still spouting how great the octa-core version will be and still lies about it being EIGHT WHOLE CORES! when there's really only four are the biggest trolls in the S4 forum.

Amazing! Where were you all these days??
BTW, I don't have to wait, nor do I have to worry about getting a I9500. Stores near me don't have any Snapdragon variant. I think it's always a good practise not to take advise from a random person in the forums.
Nobody asked for your advise on what version to get. People are knowledgeable enough to make that decision.
