I´m wondering how fast the S3 was after using S2 for long time.
S2 had reading sd card speeds of 100 mb/s.
With my S3 it goes between 35 and 45 mb/s. That´s weird...
Strangely enough, benchmarking my S3 and it doesn´t matter wich rom or kernel I use I get always the same speed.
For the rom generaly and for the sd card speed.
In antutu I only get between 12000 and 12300 (allways 1.4GHZ), no matter if I use stock roms/ stock kernels syah, speed mod or others.
In CM10 also the same.
I´ve large experience in benchmarking and android tunning with other devices, and with some tweaks here and there I was able allways to get different values with other phones.
Is somehow the S3 locked in some way?
Card speed won't vary with firmware. No matter what firmware you put in the phone, flash memory and SD card I/O is extremely slow compared to actual RAM. It is a hardware limitation, not a software limitation.
Having a Class 10 SD card helps a bit (as opposed to a Class 4).
Now to the benchmark issue:
None of the current benchmark tools are adequate to the S III. They are meant for single-core devices, and a quad-core CPU is an entirely different game.
Besides, no matter how much you overclock the phone and still keep it within a safe margin, there are other aspects that limit the result and which you cannot change. I/O is one of them. The inability of the benchmark tool to work with threads and paralel execution is another.
So, my advise is: forget about benchmarks: they are IMO utterly useless.
I mean the internal sd card not the external. I find it compared with the s2 very slow.

The s3 has dire i/o speed.
I have been doing tests all night to find out why my s2 is so much faster than the s3 and right now I See it as a combination of 2 things.
the s3 has much higher ram demands due to the higher resolution (and also the s3 tw roms are more bloated than s2 tw roms). (meaning less free ram)
secondly the i/o performance is worse on rom memory. On the s2 it has a internal sdcard for storage and dedicated rom memory, the s3 only has the internal sdcard which is also used for its rom. This dedicated rom memory on the s2 is way faster than the internal sdcard on the s3.
I also have a s3 mini here now which is also snappier than the s3. Again it uses way less ram than the s3 so more free ram for caching etc. but not as low ram usage as the s2. The s3 uses its intenral sdcard for rom like the s3 (so shares the same cost cutting as the s3) so suffers from the same low io speed.
free ram on tw fresh install.
s2 - 480meg
s3 mini - 412meg
s3 - 210 meg (yes ouch)
time to load widgets tab on tw launcher first time uncached.
s2 - 0.3 seconds
s3 mini - 1.8 seconds
s3 - 2.4 seconds
apps stay cached much longer on the s3 mini over the s3 which hides the poro i/o performance better.
I am curious if they fixed the i/o issue on the s4. But its easy to see why the s3 lte and s4 got given 2 gig of ram now.
This makes a mockery of those reviews that called the s3 mini underpowered, since the s3 mini has a smaller screen to power than the s3 as well as a smaller less bloated rom, meaning the s3 is more underpowered than the s3 mini. on aosp based roms the s3 is faster than the mini but the s2 remains faster than both.

That'd be wrong. They all have an Internal Nand chip as the phones memory. No dedicated memory and then an actual SD card as the internal. Its all the same. Its all one chip. And the internal card usually has better performance than the external one.

I believe you are seriously confusing things here - the internal nand is very likely the same.
That being said the amount of free RAM is very important. Also on S2 you might see the external microSD (with certain ROMs) as UMS instead of MTP (which is the normal one in S3 - but there is UMS with rooted RONMs) - Universal Mass Storage can be a huge lot faster since it is "exclusive in block-device mode", while MTP is shared in a file-mode style.
Comparing s2 with s4 sd card test in antutu the diference is not great 345 s4 250 s2. Maybe processor is kicking things and memory is same?

you are right in the sense I cant be sure that the onboard storage used for s2's rom is faster than the s3, it could be due to the software implementation or other reason.
But certianly most of the i/o related functions on the s2 are a lot faster than my s3. The s3 only is on par (or faster) when it hasnt got i/o to do such as loading a cached app or not having to write anything.
Im still working on the performance gulf as the gap is huge. Surely others would have noticed by now if it was such a big gap? hence I am still trying to treat it as some kind of config/kernel/rom issue.
on benchmark apps my s3 beats the s2 shame its not the same in real world performance. My s3 is also beating other s3 scores I have seen submitted.

on my s3 the internall sdcard has space partitioned of for the rom as you said,.
not the case on my s2. or if it is the case on the s2 then the sdcard is bigger than 16gig.

I agree with you. S2 and s3 roms are more or less same size. And after install you get a lot more space in sd card. S4 as same prob. After rom install you have only 9 gis free!!!

Its a 16 GB Nand chip. Partitioned for the ROM size. that's why you have the different sized space available to the user. As the ROM gets bigger, less and less space is available to the user.

if adding up space for user, cache, rom, on the s2 its bigger than 16 gig.
on the s3 it equals 16 gig.
conclusion?
on s2 rom is not on internal sdcard.
s3
1 gig cache
1.5 gig system
11.4 gig data + media
total useable space approx 14 gig.
s2
100 meg cache
500 meg system
2 gig data
12.1 gig media
total useable space approx 14.6 gig.
expected useable space on a 16gig sdcard 14gig. so where is this 0.6 from on my s2?
Well using all the s devices s2 s3 and s4 I feel always s2 smoother in ram operations. The s3 was a bit faster due better processor. That was allways my feeling. If the s2 was a exynos 4x with 1.2 where faster then the s3. Thats my feeling. From s4 to s3 its a huge improvment. It s not so a great diferrnce like from s2 to s3. Its more like from s1 to s2.
Sent from my GT-I9505 using xda premium
seen some clips of the s3 and other s3's seem faster than mine which has me curious if mine is faulty now as it remains clearly slower than my s2..
From time to time it happens to me. The workaround I found was to full format the phone. (there s some script around to do that). Reflash the phone full stock with odin and let it dtay for one or two days. After that phone works fast again. And when you feel phone laggy, restart phone. S3 as very bad memory menagement.

My tw taskmanager shows only 340mb ram instead of 512mb, after some research I found that the rest of the ram is used for ramdisk,is that true?
If so,is there a way to use all of 512mb for ram?And does this make Epic inferior to Vibrant,Captivate and Fascinate or better?
All Galaxy S phones have 512 MBs of RAM. And I do believe all are the same. At least the i9000 and the Epic are.
The phone has a physical 512MB of RAM, but I don't believe that the stock kernel currently supports more than 340MB.

Check your built in taskmanager(by holding home button),it only shows 324mb total ram,so no they not all the same.Yes we do have 512mb but only 324mb(give or take few mb) is used for actual ram,the rest is used as ramdisk(cache).Vibrant and Captivate uses whole 512mb as ram and internal rom(hd) for cache,im not sure about original Galaxy or Fascinate.
Believe me extra ram not being available has huge impact on performance,i owned MT3gs with 512mb ram and 600mhz cpu and it felt just as fast as my Epic if not faster even with Sense.
This could explain big lag im getting with 4-5 apps open,i could have 10 apps open on Mytouch slide with no lag.

There is a reason why. There is no dalvik cache push to sd for our devices yet. If we could get an ext2 or ext3 or ext 4 for our sd cards and move the cache there, it would be a whole new ball game. But it's no availible for us yet
Maybe to balance the phones out because epic has 2 cameras and keyboard
Sent from my iPod touch using Tapatalk
I wonder if other models have same ram or they have full 512mb of usable ram without ramdisk,and does that makes epic faster or slower?
I know my MT3gs was way faster with stock sense 600mhz cpu and 512 ram(without sd cache),sounds like this phone needs that extra 128+ram because extra ram makes more difference than faster cpu,324mb ram I dont think is sufficient for 2.1 to run smoothly.Hope someone comes up with something so we can use whole 512mb as ram and internal rom or sd for cache.
The reason why we have only 320 showing is because samsung moved the cache there to prevent the lag some people here talkming about the galaxy s having.

supposedly the GPU uses 128mb of the ram
All 5 galaxy s phones have 512mb but the epic and fascinate are limited to the 300 and something because our phones are the only ones that don't have a massive amount of internal sd like the others. We ours uses the more typical smaller amount of rom and the missing ram is used to stop touchwiz from lagging! Why do manufacturers and carriers keep ****ing up android!? Love this device but I can customize it myself just fine without the extra tw layer eating my resources and slowing my upgrade releases!

We have 512mb rom which can be used for cache,i have all the apps I need installed in /system/app folder and still have 400mb free,how much should be dedicated to android swap 128,256?So there is plenty of room and for those people that have about 100 apps on they phone they need to wait for a2sd.
Still no one has answered if its possible to use whole 512mb for ram,this phone really neads it,most of the time I have 3-4 apps open and about 80mb ram free-thats not good.Epic has fastets rom out of any model,now if we could use it for cache and a2sd for apps,plus whole 512mb as ram,than this thing would fly.128 for swap is a waste,plus I think that this 128mb actualy takes away from GPU's vram.
I agree that we need more RAM. There has to be a way to edit the kernel and get more out of our hardware.
Hello guys... I'm galaxy S3 user. I just want to know that Galaxy s3 & htc one x has same 1 GB ram but for galaxy s3 its showing 778 mb ram in hardware information but htc showing proper 1 gb ram. why this is? Infact, i noticed all htc have same ram as in hardware information bar. Mean s3 have less ram acording to htc one x?
Some RAM is reserved for camera, hardware decoder, etc. I doubt HTC used separate memory chip for each of these, so ONE X software must be reporting false values.
BTW, there are 833 mbytes of RAM available on latest JB leaks, and enthusiasts are looking for a way to increase this number further.
How dare you mention that name here

Thanx all for giving information. But some says that ram reserved for system & some says reserved for camera & hardware.. hhhmmm then what about htc ram? Is it shows proper 1GB ram included reserved system ram or excluded system ram as sgs3 has.??? By mean as shows 778 mb out of 1GB then where is 222 mb ram which is left. Is 222 mb ram reserved for system use?
One X has more free Ram but everyone who tried both says S3 uses it's Ram better, and the US proves bigger isn't always better.

You are wrong. This has nothing to do with the phones themselves but chip manufacturers. Look at the HTC One X LTE versions, they only have 600mb of RAM.
Yes the International version has close to 1GB of RAM free. This is mostly due to Tegra 3 having dedicated video ram to their GPU where the Exynos and S4 do not.

Yes, we can squeeze out as much ram as possible but I believe a good portion of it will always be reserved for hardware.
I did a lot of studies with my US One X and the International One X.
Anyways, to answer your question it is the Tegra 3 chip set that has 1GB of RAM, it's like that on the Asus transformer also.
Compare the US One S and One X, you see the same Ram usage pretty much and same SoC. But the international with Tegra 3 and everything else that uses a Tegra 3 from what I have seen (there might be some with 4glte radios that require ram also) has 1GB of RAM.

No, not at all. RAM, CPU and (if the gui is properly programmed) GPU can all affect how your phone functions and feels. The S3 uses a more better engineered chip set than the Tegra in the CPU and GPU department.
Most importantly is software though. As the way things are, if Android doesn't figure out a way to optimize their OS to universally work for any kind of hardware it might lose out to WP8.
Not in the hacking department though since WP8 will be closed source.

Tegras don't have dedicated GPU RAM, they don't differ to the Exynos in the way they handle that. The reason is purely software based, and some SoCs having reserved memory spaces for internal functions. I have now 856mB useable on my kernel for example.
The leaked jb firmwares gives you 833mb ram.

See that would make sense if every Tegra device from different companies like Asus, htc and Motorola, etc would have different ram uses since they all build their roms with custom ui, etc. Every company has their own custom kernels as well. But that is not the case, or is it a giant coincidence most if not all the Tegra devices show .950 gb free of memory? Including the Nexus 7.

what i mean is..is there a more direct and simpler route to change where automatically nandroid backups, apps, settings etc....
only memory issue I find with my supposed 1GB memory on my tablet and on my Galaxy Nexus phone is the one that takes 300MB away from the the total amount of memory reported by the phone's settings (and any other app that looks at the hardware)... Cannot wait for Jellybean to come out for the Tab 2 10.1, it fixed all my issues with my Galaxy Nexus that could be fixed...
Heya folks....i read from many sources on the web saying that internal memory on android device will give better performance versus the external one. Some say that even the best class 10 micro sd will perform not as good as built in memory especially when loading HD games.
So I'm planning to buy android phone which has large built in memory, in this case i pick sony xperia TX, but now sony has launched a new device which is xperia SP. It has the qualcomm S4 pro and adreno 320 which is better compared to TX's S4 plus and adreno 225. But the problem is it has a small ammount of built in memory (about 5gb user available). Which one should i take?

In my view you should take the Xperia TX with the higher amount of builtin memory.
I'm shure that you won't need a high-end processor for your daily usage. It has also enough power for the most games available in google play.
And I can say that you don't hav a much fun if the internal memory is to low, especially if you're planning to play hd-games wich will probably need about one or two gig of memory
So in my view you really don't need the SXSp...
I hope this helpes you a bit,

And sorry for my bad english - I'm from germany
You could also just get a HTC One or a Samsung GS4 wich hav both, big storage and a nice processor...
Bigger internal memory ruless...
I usually put huge data game on internal memory, it reduce lag n rendering time (trust me, I done compared it)... But I still have 32gb class 10sdcard to keep media like video,music n stored picture..

Is it just me or does Grand Theft Auto III not run very well on the s4? Even with draw distance all the way up things sill pop in, and unless I lower the resolution quality considerably, to the point of becoming blurry, the frame-rate is sluggish? I thought since this is a powerful device it would run this game no problem. Also I just got the update for app 2 sd capability, which doesn't seem to move the ENTIRE app over to the sd so it still doesn't help with storage.

The above is probably right. There are many different circumstances---does your Galaxy S4 still have stock rom with all of its bloatware? Also, do you kill your applications to free up your device's RAM? Although the S4 has 2GB of RAM, the Android OS takes up about 900MB with the TouchWiz UI while idling. Having apps such as Facebook run in the background and take even more RAM. ALSO, the developer might not have optimized the app for your devices specifications, usually to limit what speeds the game can run at to allow other users without top-of-the-line phones to run the game (efficiently) for their devices. Again, just too many reasons this could be slow for you.

As far as the ram goes...android is very differnt from pcs and laptops when it comes to ram...you actually want to use as much as possible, having a 900mb free of ram or 100mb free should make no differnce in performance. There is common saying here on xda "free ram is wasted ram"
