[Q] different CPU for different regions: battery life? - Samsung Galaxy Alpha

hi,
from the informations i find at the internet, it turns out that obviuosly only the european versions will come with the octo-core CPU in new 20nm design.
For North America and China the Alpha will be powered by a quadcore CPU.

Any thoughts or experiences about battery life for the different hardwares? I read both, bad and good battery life, in reviews so far.

Digitalversus: I9100 vs I9100G detailed comparison

Very nice and detailed comparison. I am posting Verdict here, read rest on below link:
http://www.digitalversus.com/duels-...g-galaxy-s2-i9100-i9100p-vs-i9100g-ap843.html
Verdict:
While the benchmarks clearly declare the i9100 winner, after testing both smartphones and their handling of apps and games, in reality, the i9100 and i9100G are basically the same thing.
So Samsung was telling the truth when it said that the two smartphones were “perfectly similar”. Unless you’re a hardcore mobile gamer or you're thinking of keeping your S II for years and years, you might want to choose the i9100G for its lower heat, in hope that the often underclocked components will reasonably prolong its lifespan. Plus, there’s the extra hour of battery life in video mode, which is a full 20% increase compared to the i9100. And it’s highly unlikely that during use anyone will notice the difference in responsiveness detected in our tests.
But let it be said that Samsung could still have been more forthcoming and presented the i9100G officially as, say, the Galaxy S II “Endurance” version. And it could have mentioned clearly on the packaging and website that the lower clock rate on the newer version reduces the components’ heat and increases the battery life. People would have appreciated the move and understood their reasoning better.

PS: I suggest mods to make this a sticky, so that people stop asking for I9100 vs I9100G comparison.
So, no comments?
I appreciate your post, Nice one Bro~
True. Not much difference but only lack in terms of custom rom and development for I9100G.
It will be super great otherwise.

They say G is under clocked I dont think so.There may be some difference in governor logic but max speed is same both at 1.2 GHz. I can see frequency shoots to 1200 Mhz even for a fast swipe.Actually OMAP SoC is more open than Exynos.Much information is available in public domain.Hope we will get more developers soon.
Problem is that the OMAP doesn't keep the max speed in benchmarks. If you can see the graphs again, whenever the CPU is at 1.2 Ghz, the benchmarks of I9100 and I9100G are the same. Only thing weak is GPU, but for 800x480 screen, PowerVR SGX 540 is very good. And then you have reduced heat.

Why not? With root access and custom kernel, we can always keep the max speed.

What you said, and that the G version has better audio, from what I've heard. I find it interesting that the review didn't test this.

Yep, it's better than the I9100 Yamaha Chip Audio.
I have asked them to check the sound quality for both phones. Lets see if they do.
Frankly, I listened to same song on both I9100 and I9100G on same Philips head phones, and couldn't find a difference. So, its subjective, unless some sound tests and graphs etc prove to me that I9100G is superior.

[Q] Quadcore or dualcore, which one ?

Hi every body,
I'm looking for an answer that I've the opportunity to buy the S3 quadcore international version or the dualcore LTE version.
Which one have the best benchmark ?
Which one have the less battery drain ?
I'm french ... so does the LTE version be compatible with french 3G+ ?
Thank for your answer
If you mean hspa+ for 3g+, i think it should work. I'd take the dual core over the quad core, as it is based on a newer architecture and android is not even optimized for dual core properly, let alone quad core. The snapdragon s4 beats the exynos in core to core performance. It should also fair better in battery as well, but may fall a bit short in benchmarks.

Question About Galaxy SIII

I just got the international version of the SIII. I was wondering if I should return it and get the AT&T version because some people say that it is faster graphics and memory wise, and that even though it's dual core it has a newer processor architecture (A9 vs A15). I want to know which one really has the better graphics performance and per-thread performance, just overall which one is more powerful in the end. I dont care about network speeds.
CAN YOU PLEASE USE THE DAMN SEARCH FUNCTION BEFORE POSTING?

It has more memory (2GB vs 1GB) but a slower graphic engine. Note that slower is a relative term; the speed differences may be neglectable in most real-world applications, but synthetic benchmarks do show them.
it has a newer processor architecture (A9 vs A15).

Yes. However none of the new features (such as Virtualization) are even used.
Note that an architecture doesn't say anything about the CPU itself since Samsung has heavily modified the ARM design.
Also note that the US-version is dualcore at ~1.5Ghz with the Exynos (international) is 4core clocked at 1.4Ghz.
The Exynos is also produced with a newer technology called High-K metal gate which allows higher clock speeds with less power consumption as compared to the old production technology used on the Dualcore version.
My best guess is that everything you'll want to do will just run fine on both versions, but the international one definitively has more horsepower.
The US-version with it's 2GB of RAM should be better for multitasking tough.
I got the international version and I think I made a good decision getting the international version.
Thanks so much. I looked around but couldn't find exactly what I was looking for there was always people saying the Snapdragon S4 was better, but i didn't know if they just meant battery/data wise or what. Thanks for the clarification though. So far I am loving my International version.

samsung galaxy s4 snapdragon or exynos

Hello everybody,I'm about to buy a samsung gs4 ,but I'm still wondering which one of them is better snapdragon or exynos ?
I've been heard that they are some trouble with the exynos version especialy with heat level . and the performance of the exynos are better then snapdragon .and the batterie life is better with exynos.At this point exynos version look better but overheating problem still worring me
And you figured the Verizon forum, where 100% of the devices are Snapdragons would be a good choice?

@yasay,
In my experienced, I did some research before buying my Exynos S4 and here are the pros / cons I found:
Pros:
performs better than the snapdragon versions (you can look for benchmarks in youtube)
never experience overheating, but I heard some people reporting this kind of issues
At this point there are many ROMs available for the exynos variant in case you want to use something different. I my case I used Omega Rom and I was very happy with the performance and the battery life (almost 2 days)
Cons:
I'm from Costa Rica and here the Exynos variants are for GSM 3G | HSPA+ networks. If you are in a place in which you have LTE available I suggest you get the snapdragon version

Exynos 9820 Performance

There's too much misinformation around and once I get my unit I will have about 28 days to decide if to keep it or skip this generation, I would like to use this thread to build evidence on how good or bad the international version of this device is, if Samsung scammed 90% of the world then they don't deserve our money.
I'm getting mixed feelings about this chip, In speed test G the 855 beats it by a huge margin, so most people went back spitting at it for being a badly optimized SoC.
Anandtech's Comparisons Show super disappointing scores for the S10 Exynos version, but many of the scores presented make no sense, with older hardware of the same OEM scoring better than the newest, I don't know how much to believe that review and I hope it is fake or badly executed, to my interest, my pre-order comes with the Exynos version and there's no way to have warranty on a 855 in the UK.
Then, the positive evidence we have is that it beats every other released phone on the market in battery usage, there's no such video about the 855 yet so we can't compare them, but that's all I found about the battery of this chip.
In a S10+ vs iPhone XS Max, the S10+ again Exynos beats the iPhone on almost every application, I didn't expect that to happen since it almost never happened, the apps are supposedly the same most of the time and they might as well have completely different algorithms to do the same task done superficially, but generally iOS apps are cleaner inside and their developers have higher standards of work, so how can Exynos be THAT much better?
From what I see the Exynos 9820 is not as what is perceived here on XDA....

And that's a demo unit with 6GB of ram, there are even higher benchmarks with real ones around:
https://browser.geekbench.com/v4/cpu/12211126
But everyone is dismissing Geekbench as "not reliable", and in a way it is not reliable since it doesn't demonstrate the effectiveness of a good scheduler, even the crappiest ones will be pushed to maximum performance once geekbench runs, we need more comparisons with other tools.
it is a solid fact that the Exynos is much faster than anything else in single core performance except the apple A12 and is much faster than the SD855 , while the SD855 is faster in multi core but no by much,
my only concern with the exynos is the stuttering and frame drops and the smoothness overall , i don't care about benchmarks really , and the S10 is ultra fast in launching apps already in both the exynos and SD855 , but the main concern as i mentioned is the smoothness which i think will be related to how the KERNEL will handle & is optimized and if was targeting performance or targeting efficiency only.
