I just found this picture
dev.odroid.com/wiki/odroid-t/pds/FrontPage/s_blockdiagram.jpg
So does it mean only 384MB DDR is available in system?
May be this is the reason why 305M ram shows in JP3 firmware.
That could make sense.
I wonder what the difference between them is?...Could one be dedicated to the GPU or in charge of background stuff?
Did anyone notice MFC 1080p 30 fps there?
That system block diagram isn't a Samsung official one, and frankly, i think it's wrong.
If the main memory in the Galaxy S was LPDDR1, we'd see lower GPU performance, MUCH lower. Memory bandwidth is everything when it comes to GPU on mobile devices like this.

GPU RAM must be OneDRAM，OneDRAM is much faster than normal DRAM.
You can google "OneDRAM".
So I guess we might not really have 512MB of ram (as advertised)... isn't it? I mean, if these MBs are reserved to GPU use only. There will come a day when they will be needed for other use than graphics :|.
They are not reserved for GPU use only.
OneDRAM is like an intersection for routing information with as-little-as-possible blockades in the middle.
Splitting the memory to "conventional" ram and onedram is going against the very principal of onedram. I am having a hard time to believe they actually did that.

There is no official statement about RAM size.
I noticed the diagram says "TFT LCDC". That seems wrong, does it not?

This. You'll find a lot of press about the Galaxy S having 512mb RAM, but where does Samsung itself advertise this? I cannot find anything about it anywhere on Samsungs website. Maybe we should ask them?
GSMarena pressed on the issue when the phone was released, and samsung replied that there are indeed 512MB.
Lol....So do we actually know if it has 512MB of RAM or not? As some others have stated it might help explain why the Sammy has lag issues and the Desire does not..
BTW, I dont own either at present and am just going by what I have read in these forums.
That diagram also doesn't list wireless N, does that mean our phones don't have wireless n???

well..... using my onboard math processor I compuete that 384+128 = 512..
So samsung wouldnt have been lying if they had said there was 512.. even if 128 might be dedicated to the gpu or something else. 512+128 would have been nicer though.
I wonder if this diagram is accurate.
The picture is of ODROID-T which is a tablet style device for developers.
Its hardwares are quite similar to SGS but I don't think this block diagram should be showing exactly the same informations as SGS's.
Have a look at this site;
http://dev.odroid.com/wiki/odroid-t/
Well, the S5PC110 doesn't have the memory built in beforehand. It's changeable, the controller supports OneDRAM, LPDDR1 and LPDDR2. You can stick whatever you want in there.
Remember that only what's in the blue square is the actual SOC.

How does this differ from the HTC Desire setup? I know it has 576 MB RAM, but not sure how its split up...
Well, I checked before posting. Google for an official press release from Samsung Australia. Xda is not letting me post external links due to my low number of posts. However, I love my S. I'm just saying that this mem thing is starting to smell a little bit of i7500, from a customer relations' POV. Let's just hope we actually have a different design and that, as rumors say, new kernels will unlock all available ram.

I also found a tear down analysis of Korean version galaxy s.
The author said it has "4Gb NAND+3Gb DDR+1Gb OneNand",which is incorrect.
Some comment below said it is OneDram actually.
If not for the OneDram,How can samsung declare 90M triangles/sec instead of powerVR's figure of 28M triangles/sec.
OneDram is more expensive than DDR.
I guess samsung does't say anything about RAM because it's a different structure,and hard to explain.
gosh i have been lurking on these forums to buy this phone
but with this memory issue it seems like the OMNIA II all over again
there the phone was advertisied with 512mb but only so little was left to the user!!

Can anybody explain how android handle multitasking.How such a famous OS is poor at mutitasking?For example when iam using stock browser with stock music player running in background,iam not able to use other apps like webster dictionary or xda app.Everytime one of the task gets automatically closed..So kindly explain how android os closes apps without permission from user? or before closing why dont android warn user to manually close the task according to piority.I think even symbian can do better multitasking than android.

It's due to low RAM.
When there's low amount of free RAM, android will kill some running apps to free up some.
I don't really know more details, but you can tweak this behavior using RAM scripts or your own lowmemorykiller values.
I think ~1GB of RAM (like SGS2) will be really good for multitasking, but SGS1 RAM is a bit low.

As much as I want to get a SGS2, the battery life on my SGS with a 1650mah battery is too good to pass up right now.
Plus the SGS2 is too big of a form factor for my liking.
Honestly if the SGS released the exact same identical form factor successor with 1gb on board, I would buy it in a heartbeat.
I also have a Motorola Atrix, but I ****ing HATE Qhd! Sure the ram makes this phone much snappier, but the small text is a PITA that is almost a deal breaker for me...

In this world of patents and sue sue it's harder to implement new ideas in anything even if it cam from youe own mind you will still have to check it first that is there anyone who has this idea before. i am hoping android will do great in future when pc quality hardware will come into these tiny devices, 2gb of ram quad core processors
Try talon kernel. It uses zram which is compressed virtual ram. You can have a half dozen apps open at once at the cost of brief lags swapping between them. I have listened to music, downloaded a 100mb file and Web surfed without any aap killing!

leaked specs of the Samsung Galaxy S3 say it will allegedly pack a 2GHz quad core into its 9mm metal and glass frame.
I'm getting me one of those when they are out.
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?
Sent from my SPH-D700 using XDA
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.

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.

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.
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.

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.

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.

Likely not, you will need a compatible ram chip. Even if the larger chip is compatible, the board or kernel may limit it to just 2gb. 32bit devices cannot use more than 4gb anyways. The best you can do is to just increase the swap.

I have been having the same thoughts as you. On this device, the ram is actually not built in the soc as most smartphones and tablets, its it separate from it on 4x512mb chips.
I got the tablet recently and the first thing that came across my mind was changing the thermal paste, the factory one is really garbage so I cleaned and replaced it with arctic mx2, under the heatsink of the soc and the ram there is some sort of a graphite thermal pad, which is not very efficient, I replaced it with thermal paste as well. Unfortunately I didn't take any pictures, so idk what are the ram chips exactly, devcheck reports that the device has lpddr3 1066mhz ram but I'm not sure if that is trustworthy.
IMO upgrading the ram to at least 3gb is very possible, now the question is what kind of ram chips we need and where should we look for them.
Tegra K1 is practically the fastest 32-bit soc in existence, so more ram would definitely help it out a lot. I mentioned it in another post but on the latest firmware the ram usage is abnormally high on this device, sitting at about 1gb at idle(no gapps, LOS) while it should be closer to 500mb.
