[Q] Why don't do all of this? - Nexus S Q&A, Help & Troubleshooting

i readed there : http://forum.xda-developers.com/showthread.php?t=779602&page=5 , something about the gpu of our i9000 .
why don't do all of this ???? :
To unleash the real power of Galaxy S SGX 540 GPU, there are several thing we can do as I see it.
1. FPS is limited to 56/57 in kernel (unlock it in kernel to 68 FPS =>Quadrant reports the Galaxy S screen refresh rate is 68Hz)
2. GPU is clocked @ 200MHz (unlock it in kernel to 275MHz-300MHZ=>LG Optimus 3d GPU is clocked 300MHz)
3. Implement latest updated drivers in the kernel (LG Optimus 3d uses an updated driver).
Disable VSync?
By looking at the kernel from LG Optimus 3d, implement the drivers in SGS kernel, etc... we can unleash the real power of Galaxy S SGX 540 GPU.

Seriously. Why is it so difficult to read the rules (and they are quite simple really) and post your questions is the right Q & A section??
This is just the development section not to ask questions.

56 FPS and 56,000,000 FPS are the same exact thing on a 56 Hz screen.
Also, wrong forum.

sorry for the wrong section , if anyone can move it please do it .
thanks

Adreo 220 vs Mali-400..which one is faster and more powerful ??

guys..which one is faster and more powerful..Mali-400 or Adreno220 ??
my sensation running Android Revolution HD.. CPU overclocked to 1.5GHz and GPU overclocked..
i can't get scores like GS2 (stockROM) or better than him !!
If I'm not mistaken, the Areno 220 can push 1080p stereoscopic 3D.
The question is whether the manufacturers wrote drivers to help with the hardware acceleration, which is what Samsung did with the Exynos-Mali400. =)

This site is also very informative http://www.droidgamers.com/index.ph...1661-dual-core-beasts-the-decision-to-buy-one
Mali-400 MP4 is better.
i have htc Sensation and i think Mali-400 is more powerful and faster
i installed Fruit Ninja HD Crazy (modded version to get alot from fruit in arcade mod) so in htc Sensation even with overclock i get lag..in SGS2 without custom rom it's so smooth
in quadrant i use advanced edition in 2D always i get like 330 and 3D i get from 600 to 1000 with overclock..in SGS2 without anything in 2D get 800 and 3D 1200 !!!

sensation performance / aSMP info needed please

Hi,
i recently return my samsung (4th time) galaxy s2 becouse of various defects , i been looking at the sensation however i have a few questions , firstly for all its issues i like how fast and responsive the galaxay was however when i tryed the sensation i noticed its not as smooth as the galaxy or that much smoother then the desire hd.
One possible reason for this i noticed was that the sensation uses a asmp cpu , which seems a bit cheeky to me. I mean im buying a dual core phone so i would like both cores to work at the same time as opposed to one working then the second kicking in when the first is loaded. From what ive read ics should have better support for this setup , so i was curious does anyone think we will see that much of a difference bearing in mind the sensation is asmp.
I notice there`s a lot of talented devs from the desire development and hd which is encouraging so i was hoping to learn from various users how much of a performance increase there seeing in custom roms ie is the browser jerky like stock ??
Appreciate any / all feedback thank you
I'm interested in some more more info on this topic as well.....

Read up!
ok so aSMP doesn't really work in the method of core 0 gets loaded then core 1 kicks in, thats way off.
basically SMP cpus like Tegra and Samsung's both cores run at the same speed, so core 1 follows core 0. This doesn't mean that core 1 is actually processing anything. In most cases due to gingerbread the phone is still mainly running on one core unless the app supports multicore.
aSMP allows the cores to run completely independent. This is great for battery life. Core 0 can do things like play games and stuff at full speed while core 1 handles background data.
so playing angry birds while syncing photos on flickr:
core 0 could be running at full 1.5Ghz
core 1 could be running at 500Mhz just do handle the syncing
This is basically the idea. We will get better support with ICS for full and proper support for multiple cores and the kernels will only get better as devs learn.

Hi,
Thank you for you detailed reply ive been following the thread you posted which is what led me to posting question here , i obviously misunderstood what was being said. That being said im no expert but if i buy a dual core phone id rather have both cores committed to one task like pc ... this is one of the things thats making me hold back on sensation. Althougth its a great phone with great ui and fantastic potential with future updates and dev support to the touch at present the galaxy s2 just seems smoother with the way its doing thing.
As i say thou im not expert i can appreciate theres other factor to take into account such as kernal etc, im just going with hands on usage and trying to evaluate the future potential for both devices before making a decision to which i should choose

The sensation's CPU works in a much more power efficient way, while still offering the speed of any other dual core CPU. It allows different clock speeds for different cores so applications using only a single core will be able to clock it differently to those using the other in the background. Computers, especially laptops work in a similar way, as there is a need for power efficiency. Realistically the Galaxy SII runs smoother due to it running a much less resource hungry skin on top of android, but both the CPU of the sensation and the Galaxy SII are both of a similar calibre, so it is very difficult to say which is better.
again thanks for the reply , defintly understand how this asmp buisness works more now which has given me some stuff to think about

Neither architecture, SMP or aSMP, will commit both cores to one task unless the app is multithreaded and it currently needs the use of both cores. This is the same way that multicore pc's operate. That's why when quad core CPU's first came out people said that they didn't feel any faster than comparable dual core chips - most existing apps at that time were written for single or dual threaded use so the third and fourth cores largely sat unused. The pc doesn't just force the use of the extra cores just because they are there (regardless of how they scale, aSMP or SMP).

Also the new firmware has made it smoother due to extra optimisations. Web browser is not as good as the galaxy S 2 due that being GPU accelerated. Power wise the Sensation you will get somewhat more out of your battery life wise.

If you look at my thread and see the post:
MSM8x60:
Adreno 220 GPU
2x Cortex A8 Based Cores
512KB L2 Cache
45nm
upto 333Mhz LPDDR2
Exynos 4210:
Mali 400 GPU
2x Cortex A9 Based Cores
1MB L2 Cache
45nm
support for LPDDR2/DDR3
Tegra 2:
ULP Geforce GPU
2x Cortex A9 Based Cores
1MB L2 Cache
40nm
support for 600Mhz LPDDR2
So the biggest thing is is that the Exynos is based on a new core micro-arch then the Snapdragon 2, also it has the ability to support DDR3 memory. To go into more detail about ARM Cortex.
Items that A8 and A9 have in common:
Jazelle RCT for JIT Compilation
Neon SIMD Instruction Set (Optional)
Thumb2 Instruction set
VFPv3 Floating Point Unit (Optional)
Cortex A8:
Superscalar Dual-Issue Micro-Arch
2.0 DMIPS/Mhz
Cortex A9:
Out-Of-Order Superscalar Micro-Arch
2.5 DMIPS/Mhz
Jazelle DBX for Java Execution
Dual-Core Processing Built In
The SGSII has a new generation architecture as so does the Tegra

+1 to your request!
I suppose is not so much different to Prada 3.0 phone, maybe you can use same rooting method and same recovery
http://www.phonearena.com/phones/compare/LG-Optimus-L9,LG-Prada-3.0/phones/7459,5758
Same tri-dual platform but different screen, resolution, dpi, camera and battery.
It may be worth an attempt.

Adreno 225 at 720p and mali400?

Hey guys was hoping you could help me out since I am a big newbie when it comes to the mobile world
I am looking to buy a new phone, and one of the phones I've choosen to buy has adreno 225, 1.5ghz krait and 720p 4.7" screen (its the pantech (or SKY) a830l ).
Was hoping you guys could help me and let me know which games and/or apps (if any) I wont be able to run because of gpu bottle-neck on this resolution, and how future proof the adreno 225 will prove to be..
additionally, my alternative choice is htc One X
One X is almost twice the price of the pantechm , so I want to know whether its really worth it in terms of cpu and gpu power (ignoring the better screen for a bit).
Also, I've noticed that many 'very' powerful cell phones have mali400 (including galaxy note (1) and SIII). I've heard people say that adreno 225 is better than mali400 AND that SIII outperforms in games cell phones with much more powerful graphics card. So now im really confused. Am I missing something?

mali 400 easily outperforms adreno 225... that's why it is in galaxy s3
and it has capability upto 4 cores so it is better
more comparable to it would be adreno 320!
the "pantech" one is a good choice if pricing suits you! You'll be able to play many games but i assume 1.5 ghz krait is either dual/quad core!! If yes you are good to go!

thanks for the reply, really appreciate the clarification.
Ive seen a couple of benchmarks but benchmarks are just benchmarks. Based on current games an apps, how many games and apps are there that wont be able to run because of the gpu? and can you give me some examples? hope I'm not asking too much :angel:
the pantech 830 is Super IPS LCD 720p (4.8"), krait dual core 1.5ghz and adreno 225
Samsung galaxy Note (N7000) is Super Amoled 720p (5.3"), cortex A-9, mali400, about 25% more expensive than the pantech
HTC One X is about twice the price of the pantech (and I really doubt I need the quad core)

Well the pantech phone will run almost all games.. Games which have state of the art graphics like nova3,wild blood and latest nfs, asphalt releases might be a problem.. But those can also be made working by rooting and enabling hardware acceleration
Note and one x will run all games but i understand they are costly
Then again it comes to u, how much u want to pay!

thanks for the reply..Im willing to spend more but I just dont want spend money on hardware which I wont be utilizing. Id like to game on my mobile, but not dying do and dont mind if a few games dont work. Prefer gaming on my PC in any case.
Just want to confirm that all apps would work and I could run 720p videos on the pantech smoothly.

Overlocking GPU??

recently i came across overlocking GPU.. in sense4a built by derefas made GPU overlocked to 220 n he mensioned that its safe.. is i dont think it wont create any problem.. some problem ll exist.. can anybody know that problem?? and overlocking to 220 means now we have adreno220 ?? is it like dat?? n i google it but i saw that for adreno220 it clock speed would be 1.2Ghz to 1.5GHz(acc. to this site - http://en.wikipedia.org/wiki/Imageon). so that rom has gpu overlocked n cpu optional, it means iguess it make some problem.. can anybody explain me pros n cons..:fingers-crossed:

No, it ain't like that. The chip is embedded, and can't change.
Our Chipset is MSM7225A (according to http://pdadb.net/index.php?m=specs&id=3073&c=htc_explorer_htc_pico) and the GPU supported is Adreno 200 (enhanced) according to (http://en.wikipedia.org/wiki/Snapdragon_(system_on_chip)).
The Adreno 200 was said to support the following in the wikipedia site.
Adreno 200 (AMD Z430) inside the QSD8x50 (1 GHz) and MSM7x27 (600 MHz A11+L2 cache). It offers a programmable function pipeline and streaming textures with support for OpenGL ES 2.0, OpenGL ES 1.1, OpenVG 1.1, EGL 1.4, Direct3D Mobile, SVGT 1.2 and DirectDraw. (22M triangles/second, 133M pixels/second, clock speed up to 128 MHz).
Click to expand...
Click to collapse
Even some googling didn't help in finding the clocking speed of our GPU. According to wikipedia, it supports 128 MHz.
Note that it was for the devices QSD8x50 (1 GHz) and MSM7x27.
But, an enhanced GPU is supported in our Chip. So, I got the following info from the Qualcomm website.
Adrenoâ„¢ 200 is the first OGLES 2.0 GPU with unified shader architecture and makes maximum use of the graphics processing power of the GPU. This GPU is a leap forward in visual graphics quality from OpenGL-Es 1.x, which enables developers to implement effects that were previously a daunting task. APIs supported include OpenGL ES 2.0, OpenGL ES 1.1, OpenVG 1.1, EGL 1.3, Direct3D Mobile, SVGT 1.2 and DirectDraw. The Adreno 200 delivers streaming textures to combine Video, Camera, SVG and other image surfaces with 3D graphics. It also enables concurrent CPU, DSP, Graphics, and MDP and includes a programmable function graphics pipeline.

And, so, I summarized that an enhanced GPU, in our chip, has a normal clocking speed of around 200 MHz, and it can be overclocked. How this is done, and all the other stuff, the developers might help you. And, if its safe... I also read that overclocking a little wouldn't harm. So, I guess it's safe.
Anyways, the Pros are that you would get a little extra fps, so you could "expect" a little improvement in gaming and video playback.
The Cons... Well, anyone using an overclocked GPU for long might know.

When overclocked the textures are rendered little quicker than normal clocking. It won't double the frame rate as some guy doubted. Look at the details of our CPU and gpu.
