So I was wondering if there is any hack that would add more ram to the GPU, comparing to RAM hack that takes GPU RAM and gives it to Phones RAM, Could it be done vice-versa, so take ram from Phone RAM and giving it to GPU, could it be done? and would it increase GPU processing power?
i too was wondering this too because im a heavy gamer
I'm just assuming but, the RAM pool is all the same RAM chips. It's just being managed and distributed between the GPU and CPU by software.
But I'm not sure.

See subject line.
I need to admit, its a lot.
But, i wonder how the memory is being shared. The HD2 has 428MB of total Ram.
But 128MB is being used by the GPU. The question is, is the 428MB ram, really global ram. Or is the 128MB ram dedicated ram for the GPU ( like the 2700g has 16MB dedicated ram ).
If its global ram, then maybe its possible to reduce the ram amount to 64MB or 32MB, and use the rest for programs... So many open question, so little information about the snapdragon's design
For instance, the Toshiba TG01 & Asus F1, both have 256MB global ram. But does that mean that both companies did not report the 128MB "extra" ram, in there total like HTC does. Or does it mean, that they use a smaller part off the 256MB ram, for its GPU.
i'm hoping that its going to be in preperation for what comes with Winmo 7, perhaps gaming, maybe MS requires such a high amount of vram as a standard?
Doesn't it have 448MB? 320+128?

Yes, you are right. My bad. It's indeed 448MB.
Yeah. 448MB = 128MB dedicated video memory, plus 320MB conventional memory.
I suspect other vendors probably simply don't advertise video memory; it's also possible, of course, that they have a unified memory architecture (e.g. that the TG01 and Acer F1 use their main 256MB of regular memory to store video in); that might account for the Leo's 3D graphics benchmark scores exceeding those of the TG01.
Had been the same with the Xperia X1, there where also rumors that it does have (maybe has, don't know how to chekc this) 128 MB dedicated Video RAM. Don't care to much about it. It'll be fast enough anyway!

Is it even confirmed that 128 MB is indeed for VRAM, or is it just speculations so far (even though I'm inclined to think the same)?

Core requirements:
Processor: ARM v6+, L2 Cache, VFP, Open GL ES 2.0 graphics HW (QCOM 8k, Nvidia “Tegra” AP15/16* and TI 3430 all meet spec)
From that single post it states that WM7 needs a Tegra graphics chip... but from the release QCOM 8k also meets the requirements, and the Leo will have Snapdragon QSD8250 1 GHz processor..
Am I missing something?? it seems it should be upgradable to WM7.

According to B3ler3fonte who gave us details about the Leo in the general thread (here: http://forum.xda-developers.com/showthread.php?t=560143&page=48) it will be compatible with winmo 7.
In order to save some answers, I am posting you a far more detailed specs of Leo, so, as u can clearly see from the specs, u’ll notice (and I think it was a question which was circulating from loads around this thread, of whether future WM7 will or will not be supported by Leo) that it will be absolutely supported. I think we should all celebrate!!

Qualcomm 8k = Snapdragon's QSD8xxx-series chips = Qualcomm Snapdragon QSD8250 (which is in the Leo).. so the processor should meet WM7 chassis 1 requirement.

Thanks Why_999 I wasn't aware that the snapdragon was Qualcomm 8k series processor.
i think it should be reserved memory actually for some sense UI things and similar stuffs . not dedicated video RAM
Isnt 128 too much just for clouds? There are 3 variants possible:
- someone was speculating with specs in his blog and the rumor broke out;
- thats for gaming purposes( see wm7);
- thats for iphone graphics emulator)))
RAM is split between ARM cores, general-purpose ARM11 and radio ARM9. Portions can be reserved for other purposes (video acceleration for one) too. Chances are there's ~256Mb of RAM accessible from OS on HD2, which is fairly reasonable, IMO. More RAM means less battery life...
It's "just" to have the 1Go needed for WinMo7... I am sure our cookers will change this to get the best of this awesome phone
http://en.wikipedia.org/wiki/Tegra#Tegra_3
Wasjust reading this and it says the CPU goes to 1.3Ghz in single core mode. does that mean 4 cores run at 1.2 then it shuts 3 down and bumps one of them to 1.3 if it needs it?
also anyone now the memery the gfx uses
4 cores @ 1.2Ghz = 4.8 G-ops/sec
1 core @ 1.3Ghz = 1.3 G-ops/sec.
So, the answer to your question is yes and no. Under an idle condition (not sleep) where there is little processor load or runnable threads, there will be only one CPU running @ 1.3 Ghz Fmax. (It can of course be running at a slower speed than this based on what the rate governor has decided) If the demand changes so that one or more additional cores need to be brought on line, the Fmax is constrained to 1.2 Ghz, and those additional cores are brought on line as needed. It may or may not have actually been clocking at 1.3 Ghz when this happens, but probably it will be.
This answer applies to the STOCK kernels. All of this behavior is under control of the kernel, and some of the dev kernels alter this code with different behaviors.
cheers.
Niice info man. thanks very much. any idea on how much RAM the gfx uses?

No clue. Don't even know if the GPU has some private SRAM on the SoC. Consult the Tegra 3 TRM for that. But, a single-layer 24-bit framebuffer @ 1280x800 needs 3MB for a single layer. Add in z-buffering and whatever else the openGL ES (1.0 & 2.0) libraries do with offscreen/onscreen primitive storage in userland memory space and I suppose it can be much much higher than that.
Somehow I sense you are asking about kernel-reserved memory; I don't know if the kernel reserves some minimum amount of general-purpose RAM (e.g. for the framebuffer) or not. Sorry. (Use the force, read the source!)

No im thinking more a portion of the 1gb system RAM was given to the gfx to play with. so our system RAM is only say 768mb
So I've been noticing somethin strange other then the experia z every single other high end device that will come out as of 2013 will be using a 1.7GHZ snapdragon the only high end device that will use a lower one is experia z why????? I mean the phone hasn't come out yet can't they just put the 1.7GHZ instead? why use a lower one 1.5GHZ from phones of the fourth quarter of 2012 its old tech!!!

Calm down man, 1.5GHz quadcore is good for Android. Android really doesn't need such a high speeds
And CPU clock doesn't mean smoother device
Sent from my LT26i using xda app-developers app
1.5Ghz Quad Core is not "only". And they all use exactly the same CPU which operates with 1,5-1,7Ghz speed. Clock speed isn't everything. Look at the iPhone - it uses dual core 1.2Ghz CPU - yet its performance is 5 times smoother than most quad core devices...
Dual core is more than enough for anything a smartphone might need to do - as long as you put good software on it.

Seriously? "Only" on a quad core 1.5ghz CPU for a smartphone? What are you gonna run on your phone that would require you more? Or do you just want your battery to drain more for no possible reasons? Some users even just underclock for the sake of saving battery.
If you ask me I buy this because of the features and the RAM not because of processor clock.
If you ever let me choose I would rather go for a 1ghz dual core processor with 4GB RAM than having a 2ghz quad core processor with 2GB RAM.
The only reason why I would want the Qualcomm S4 Pro processor is because of adreno 320.
A dual core is good enough dude .. this is a quad core lol

What would be the purpose of 4GB of RAM in a smartphone are you running Photoshop or a VM? Where did this stigma that more cores is equivalent to less efficient power use. More asynchronous cores allow for more accurate scaling of processing power to needs, thus higher power efficiency because the CPU spends less time in higher power states.

Buddy android runs Dalvik VM and our GPU uses dedicated RAM for processing certain graphic tasks. So yes we are running a VM on our mobile phones.
Also with a proper monitoring app you could see for yourself which uses more and needs more resource here. whether processing or memory.
Didn't you even wonder why our phones consume almost 700mb RAM without even a single foreground application open? Yet it sits idle in a single core and remains in between 400mhz+ to 900mhz?
Also I didn't say that more cores consumes more power in my statement but still since each core requires power to run it should also consume more. Also I didn't mention anything about number of core I was talking about the clocks. Since the higher the clock requires more Amperes. Still underclocking your phone by 500mhz would prolly just save about 2% of your battery anyways.
you don't need higher cpu clock to get a pocket heater for this winter
My Optimus G has the same cpu an the thermal throttling is kikin in pretty fast. This 1.7Ghz S4pro will thermal throttle as fast or even faster, rendering numerical advantage meaningless.
I don't want to feed the troll but I also think dual core is good enough.

I have yet to see my Xperia ZL have less than 800MB of free an extra 2GB would be a total waste. And you simply stated you'd rather have a dual than a quad, peak frequency means very little except for potential processing power. Just because your CPU is capable of a higher clock speed doesn't mean it will idle any higher. Likewise the only difference between a quad with a single utilized core and a dual with a single utilized core is the minute amount if extra leakage current for the quad.
I think you meant to say that higher frequencies may need more voltage, amperage has very little to do with CPU frequency scaling.
And obviously the memory overhead for a virtualized process i.e. Dalvik VM is not even in the same league as a system VM.

Buddy that 800mb is without running any foreground applications other than either Settings app or the homescreen. Like I said try running some monitoring apps on the background and try using the browser then maybe try loading some sites with lots of javascript codes in it.
Or if you like try launching 4 types of angry birds and the 2 temple run games simultaneously without killing one of them and let's see if OOM doesn't kick in and kill any of them.
Regarding CPU cores please state something that requires a quad core processor. The smoothness of the UI your experiencing is because of the type of processor your phone is using "The Snapdragon S4 Pro" even if you disable all the extra cores in it you won't feel anything different unless of course you'll run some benchmark tools or video decoding stuffs in there.
And just FYI more cores doesn't mean greater processing power. It's more cores = more processes it can handle.
And on the CPU freq clocks who said t that amperes doesn't increase on each frequency table? Please take a look at qualcomm's document on their site regarding it's processors so you would know how they calculate it. Voltage is just used to provide more electricity to power up the processor but voltage alone won't make a processor active.
This discussion is going to the wrong way.

I want to raise question is it possible to overclock the CPU, or GPU or memory speed. We all know that ze550kl / z00l performance with msm8916. Is almost in the limit to run apps and games, wanted to know if possible or not, and if there is any development has this respect. I like the device and it is great but it is clear that it is getting weak in the matter of hardware, if someone can work in this respect to give a breath / power to our device

i don't think so , if its possible to overclock the processor to its frequency,
you can costumize it too max frequency of it or to lower , as u need
But if is then i would love like to know too
I am already extracting the maximum, from him that I can of him, already put using ex kernel, with governor ordenad, frequency of 200mhz @ 12000mhz, and simple GPU ordered frequency of 200mhz to 400mhz, active zram of 512mb, and entropy of 128/256, then Of course, here with standard frequency of the paddle extracting nothing more than that, the problem and that we have a large bottleneck in memory lpddr3 of 533mhz, that opera and 32bit, there is a single channel giving bandwidth of 4.2gb / s that It has to be split between CPU and GPU. What is clearly one of the pro soc power limiter, I do not know much about the arm architecture, but I can not do over clock in lpddr3 memory, since I did not see any software or tutoring Citing this. Although this would be a solution, if you do over clock in the CPU or ns GPU will force the clock controller up what will increase the memory performance consequently, something else, not good will lock the clock at maximum in 1200mhz and GPU at 400mhz, as there will be a large power consumption and the performance will be limited by the cords of the tempering control and the low frequency of the RAM, # excuse me to have been so far more enthusiastic about hardware,
even with my old htc explorer i could increase cpu clocsk from 600mhz to 900mhz why we cant do it on zenfone 2 just we need good developer and kernel
it's up to the hardware
If you look at the specs from qualcom it has a max speed and not every device is possible to reach the max, but if you have the proper kernel you can reach that speed and "overclock"
How to increase 4g ram
You can't. SOC ( System on Chip) means CPU, GPU and RAM are all in one chip. Buy a new phone if you need more RAM
