I9103
http://www.91mobiles.com/mobile/Samsung/Galaxy+S+II+I9103/9986.html
I9100 (to compare)
http://www.91mobiles.com/mobile/Samsung/Galaxy+S+II+I9100/8374.html
I mark'd the differences in yellow that I saw so far.
The main differents are the SLCD (Super Liquid Chrystal Display) and the Nvidia Tegra 2 Processor and it seems that the 1080p HD Video Recording is at 30fps in stock.
I think the new SLCD Screen will boost the battery life alot !
Any new Information about this model of SGS2 can be posted here !
I will edit it soon with more Information.
Can't wait to get it!

I cant see any difference between 9100 & 9103
Are there any?

Old info, look at the post date. Samsung has stated they don't have any plans to release this device any time soon. Micht change in the future but now it's definatly cancelled.

Screen is Super LCD rather than Super AMOLED Plus and the Processor is a Tegra 2 Processor (Nvidia) rather than Samsung's own Exynos
Exynos + Chainfire 3D ftw!!

samsung meant to release this phone because they can't answer the orders for 9100.. the samsung i-9103 has some benefits and handicaps against the i-9100. 9103 has a nvidia tegra2 graphic processor which might be stronger in some cases but lacks the benefits of the th super amoled plus screen since it has a clear type LCD screen..

just like the i9003 (AKA Galaxy S i9000 2011 editon)

- added a screenshot with yellow marks
hope that they will release it soon and not in 2012.
Then I would wait for an SGS3 !

Any news about Samsung GT-I9103
Any release date ?
BC I dont know what to do. Wait for Glaxy S II i9103, OR take LG Optimus 2X...

There's also the new GT-I9001 coming in september. It's called Galaxy S Plus, and actually beats the SGS2 in cpu-specs. Samsung.de is already advertising for it on their homepage.
Dual-core 1,4 Ghz cpu beats the SGS2, but othervise its smaller in specs - 5Mp camera, 8 Gb internal memory and so on.
So by overclocking the SGS2 a bit, it's still the strongest in the block...

It says "Ultraschneller 1,4 GHz Prozessor" which means something like fast 1,4GHz CPU, but no mention of Dualcore somewhere... so its a Singlecore, every marketing department would mention Dualcore if it would be a dualcore...

SLCD screen will increase battery use not decrease it compared to samLED+

Yes, I agree, pretty sure it is single core, probably also based on Cortex A8, so it is slower than SGS2 also in single threaded tasks regardless of the higher clock frequency.

No. The Galaxy S Plus has a single core CPU.

So many rumours about Galaxy devices... Tegra 2 dual-core galaxy SII is more of a Cinderella for now, doesn't exist and probably won't exist at all.

droidfish chess 4 cores speed test

hi
can someone install droidfish chess app, set on 4 cores and from initial board position will do analysis to see if knps passes 1000...lg g2 failed to pass 600 which is low. interesting to see it that aspect was improved with new chip/memory speed...

It's 602k.

I got 608K, also running HolyAngel's kernel as well, FYI, with CPU at 2.5 and smartassv2 enabled.

thanks to all. I guess need to wait to new Quallcom chip 805 to see if this will be improved..

No problem, just don't forget the Thanks button.
I do wonder if it's the QHD display that drags down the nps with the G3, compared the Note 3 with similar specs...

My note 3 is with Exynos cpu so it performs much better in this kind of cpu load.... i dont see any relation to QHD display which is handled by gpu part..

This is L1 cache that matters to chess... not Ghz
Dear all,
Let me contribute to that topic with some more precision.
If you are looking for more Nodes per second, the decisive criteria is the L1 CACHE of the CPU. It plays much more on the outcome compared to the frequency. I am quite sure about that after trying this test on different Snapdragons.
Snapdragons have 16K data + 16K instruction cache. Therefore, even a Galaxy Note IV can barely reach 700K despite 2.65Ghz speed of the Snapdragon 805, while its Exynos brother boosts no less than 1400K.
You may recall the Exynos is octa-core. and SD805 is only 4 cores. If we are supposed to think that's the reason, come explain 730K made with the Exynos 4412 of Galaxy Note 2 which runs @ 1.6 x 4 cores.
Exynos CPU's have 32K+32K L1 cache! That's why they perform surprisingly better. But be careful with all this big.LITTLE thing which is extremely mind confusing. I did not test a note III or a Galaxy Tab with Exynos 4+4 cpu's. They all have low freq set of cores which, if used, could seriously reduce the speed. But i guess engines like Stockfish will force the hi-freq cores. In Note-III case, that means 1.9 Ghz x 4 cores.
The L1-cache effect is obvious on Apple CPU's which have 1.3Ghz x 4 cores but 64K cache. They perform easily around 1300K.
Finally, stay away from Snapdragons if you use Droidfish and check for octa cores, capable of working together at peak speed and insist on 32K+32K L1 cache minimum per core !!!
Alternatively Mediatek octa core CPU's have 8 cores working in parallel at speeds up to 2.0Ghz. They should give 1200 Knps. MTK6592 for example is a concrete low-cost potential. Give it a try if you can. Mediatek will soon release stronger CPU's but they will be big.LITTLE too, unfortunately...
All i say above applies to chess only. Real life usage, internet, movies, games, social media etc is totally a different world and Snapdragon 805 is a monster there! Qualcomm does not and should not focus on delivering the best chess CPU for mobiles., for us, freaks and they are right in what they are doing for mass users market.

Antutu Benchmark?

Anyone else? I got 67,240 in 64bit mode on first and over 68k in 2nd. Finally figured out the screen shot.

WOW....Screenshot?

Hrm... that's actually a little on the low side compared to some of the numbers it was putting up on review units. Most of those I saw were hovering around 70,000.
Definitely curious to see what other folks pull.

I'm not brave enough to install that unsigned apk. I did score almost 58k in the standard antututu. Too be honest both these numbers are a lot lower then what I was thinking. Most of the results were on par with the exynos 5420 other then the mali gpu which scored nearly 20k (double the 5420 mali). Even the storage io numbers weren't radically different Despite their claims of high performance internal storage.
Anyways benchmarks usually only tell a small part of the story and there could be other things at play here that I have yet to discover. I'm hoping we see kernel source for this device soon.

I think this kind of benchmark is more useful and interesting as it correlates with something in real-life, like actual use of the device:

Here's mine for those that care.

Do you have any battery temperature readings when running the Antutu?

Hehe, I see there was a typo in your original measurement
Good stuff. Looks like the retail units are definitely up to snuff. Keep em coming guys.

Yes, I went back and edited it cuz I saw I'm a bit dyslexic apparently...

this was the very first run in 64 bit mode, non 64 bit was 64508,

67282 with 64bit, sorry that is such a large screenshot

It really is a beast! My friend has this phone, but I have the HTC M9 and it only gets 60927 on AnTuTu. In fairness though, the CPU only goes up to 1.5 GHz on little core + 2.0 GHz on the big core while Exynos has it 1.6+2.2 and 20 nm process

One "BIG" A57 core always active?

Hi,
Been monitoring battery performance and CPU sleep states, and one thing I notice is that on my device the A53's spent a surprising amount of time at 1Ghz+ when the screen is on, and one of the A57 cores is always running a 384 when the device is idle, while the other 3 sleep. Is this Sony's attempt to keep the UI snappy? Having the A57 on all the time (screen on), even at that low frequency is going to use in the region of 100mW+ (which is about 4x that of each A53 core)
Can someone else sanity check my results?
I'm using perfmon, systempanel, and "floating monitors"
Perfmon can be found here: http://forum.xda-developers.com/showthread.php?t=1933284
It's also on the market for the price of a coffee, please consider buying it - great tool!

Yep sounds about right this Greek review:
https://translate.google.co.uk/tran.../2015/10/24/sony-xperia-z5-review/&edit-text=
Found that in most cases only one A57 core runs in the Z5.

Pardon my ignorance but...how much worse do you think it is to run only the big cores and throttle them from 2Ghz to 300Mhz without turning ON and switching to the little ones? (In other words...disable the big little technology and just use the best 4 cores).
We're now using the little cores more than the big ones....and that 1.5Ghz cap could be the reason of a lot of stutters.
Changing the topic, now that Google is selling Nexus devices (5X and 6P) with big little. I think they will improve this ARM technology in future Android versions (including the kernel).

The little cores will be perfectly fine for most daily mundane tasks, such as checking emails, messaging etc. The stutters you mention probably is because the phone launched just before Marshmallow and Sony are focusing more on that OS, same kind of thing with the camera. The current camera app is just a placeholder for the proper app due for release in a week or two.

In short, no. The little cores, whilst relative to the A57's are weak, they are by no means underpowered for running the UI and such. Do consider that the A53 core is faster than the A9 cores that powered previous flagships such as the Galaxy S3. Leaving one of the A57's ticking in the background is probably not such a bad idea having thought about it, as it allows fast handover when the high performance is required; I do however hypothesise that some of the stuttering might be due to threads being handed over to the A57, whilst it is running down at 384, which will be somewhat slower than the high frequency A53 core(s) the process is being passed from. It may be that we see a touch-boost or more aggressive CPU governor brought in to rectify this.
On a related note, there is a good article on the power-aware BIG.little implementation in the Snapdragon 810 here:
http://www.anandtech.com/show/8933/snapdragon-810-performance-preview/4

Definitely for performance.
If they weren't set is this fashion the UI would feel sluggish and sluggish on wake up.
Your findings sound perfectly normal/adequate, resemble a "interactive" CPU governor.

Z3+ A57 - 2 cores or 4 cores

So according android central's review, the Z3+ has two of the SD810's A57 cores disabled entirely. Only certain apps (literary a select few apps like the camera or antutu) will enable the phone to use all four A57's.
(can't post links, new user:crying
I don't own a Z3+, but I'm interested in getting one. Just curious if the Z3+ still has those A57's disabled under marshmallow, otherwise I might get a Z5.
Would someone on marshmallow test their Z3+ for me? All you need to do is download and use Trepn Profiler from the play store (Qualcomm's app, sorry can't post links).
According android central the A57's are cpu5, cpu6, cpu7 and cpu8.

According to the stats 5,6,8 were running on 0

Thanks for checking!
Ok so 3 of them were disabled, maybe that's why MM runs cooler?
If possible could you play a game or something, not a benchmark tool, and see how the cpu's behave?

In my case one was showing 0 (if I recall well, cpu7), rest were showing activity during ordinary tasks as browsing, moving through menus etc...
Sent from my Nexus 7 using Tapatalk

After some in depth investigation I can confirm that Z3+ won't use 3 of its A57 when it's gets hot specially during gaming. Only one core would work and that too at very low clock. After that no matter what you do it won't use the A57 cores. The cores would fire up only if you leave the device idele for some time. But as soon as you open Chrome the A57 cores would fire up but a low clock. This is happened in the lady update. Before that on MM even when the device was hot A57 cores would fire up. But after the last update Sony has done heavy change to the governor at the expense of performance. Even my 3 years old note 3 runs the game much faster after 5 mins into heavy gaming.
Sony should provide a performance mode option for people who need high performance during gaming irrespective of the heat. But the phone would never lag in the general applications. The only problem is that high level gaming and video editing impossible on this phone due to the A57 cores becoming inactive.

To be honest I think its actually making the battery last even less time, my z2 goes faster, cooler and much longer. Really really disappointed so far in this device and I dont know if they're going to bother improving on this.
I never used the device with mm because when I got it and added the 2nd user it gone into bootloop, so I had to flash it with the flashtool.

It's how the Big.little has been configured. How I see it though is that it's a 4 core with a boost function. Um sure the 810 Uses HMp
The most powerful use model of big.LITTLE architecture is?*heterogeneous multi-processing?*(HMP), which enables the use of all physical cores at the same time. Threads with high priority or computational intensity can in this case be allocated to the "big" cores while threads with less priority or less computational intensity, such as background tasks, can be performed by the "LITTLE" cores.[10][11] wiki

I also noticed that. 3 cores are dead under pressure of gaming thats creepy.. Im on the latest mm. Hope that they will do something with it because i can feel its getting slower in direct test with Galaxy alpha g850f (with exynos).. Do someone know if this is a feature of marshmallow only or it is included in lollipop

I just tested some gaming and security software scan, and all cores showed activity more or less..
