I've been looking for a more technical analysis of these SOCs and I have been trying to learn how the async CPU setup on the MSM8660 affects performance.
Nvidia claims that the power saving feature of our CPU (async) will inevitably cause a decrease in performance:
http://www.intomobile.com/2011/03/2...ed&utm_campaign=Feed:+IntoMobile+(IntoMobile)
Does anyone have any comments on this? If this is the case, I am wondering if through software we can force both cores to run at the same voltage/frequency. I wonder if it would cause an increase in performance (at least in benchmarking). Many claim that the Evo 3d only gets medicore benchmark scores due to having asynchronous cores that are not being accurately benched. It would be interesting to verify this claim.
Also, does anyone know which SOC between the three I listed in the title is the highest in performance (not talking about useless benchmarks like quadrant)?
So....there is possibly a 10–15% decrease in performance.....that's fine with me. Most of the time you won't even notice until you run benchmarks and looks at the numbers.
SetCPU + Performance mode are all you should need

Well the 10-15% slower is nVidia's claim, not sure if its true.
Does that make both cores run at the same time or running cores at the same time not possible due to the processor

It will keep the cpu running at full speed. Which core gets used for what depends on a lot of things but it mostly depends on how the apps and kernel are programmed.

Yes, but is it possible to keep both cores at their full frequency? Setting the exynos or tegra 2 on performance mode makes both cores stay at their maximum frequency since they are synchronous. I think setting performance mode on the Evo 3d would only guarantee that one of the core will remain at its full frequency.
Not sure about this of course. Anyone have any insight into this?
Second Core wouldnt kick in if ur not heavily multitasking or running multithreaded apps and u wouldnt need second core for minor multitasking or single threaded operations as single core is enough
i will tell you that on paper the msmx60 should beat out all, but in real world use, the exynos hammers everything. the s2 is a beast
The Exynos is the better SoC, plain and simple. If we get into GPU discussions, the Adreno 220 is the best, as in better than Mali 400.. Go to Anandtech, and watch them use a Qualcomm device for the benches.

Is it a "for sure" thing that ICS will use the GPU acceleration in the OS? Or is that just everyone's hopes and dreams

You could program the kernel to keep both cores at max frequency. Im not a developer but am sure something like this could be done

Maybe we should make some real world benchmarks and get some SGS2 people in on it. Like how fast a particular app opens(say angry birds), How many fps a game plays at, Convert a file to another format, complete a 5 step plan to take over the world things like that. Alot of things like that are how reviewers rate and test things like new video cards and cpus plus all the benchmark programs.
I used to use a program called fraps to see how many fps my pc games were playing at so I could tweak stuff( long live unreal tournament!!!!). It would just display the fps in the top corner of the screen.
Also comparing the 3vo and SGS2 will really heat up when we get root and CM7. 400mb less roms have gatta make a huge difference on performance. I dunno about you guys but I haven't been able clog up my 3vo yet(and I've been trying!), I'm pretty impressed with the hardware so far.

It is known that the MSM8660 can achieve higher clock frequencies than the Exynos, though clock for clock the Exynos has better IPC.
As of right now the GSII beats the 3VO in both benchmarks and real world tests, but I suspect this is because Sense is a pig that takes far too much ram and system resources. HTC also seems to have poorer unoptimized drivers. In addition to this, the async CPUs of the 3VO may not be properly tested by current benchmarking tools.
I think comparing a rooted 3VO and a rooted GSII should be much closer. Imagine the MSM8660 at 1.8-2.0 Ghz both cores running full frequency with no Sense and other bloat to slow it down. Combine that with a hardware accelerated GUI and this phone should be amazing.
The Adreno GPU will get better over time... and will develop much faster than before. Since Qualcomm purchased the branch from AMD (ATi), there has been much improvement in a reasonably small amount of time. There are various claims that the Adreno 220 outperforms the Tegra 2. I havent seen a solid comparison of the Adreno 220 vs the Exynos although I have read that the Exynos is a very capable processor.
As they both stand in stock offering, the Samsung GS2 will be faster; it has tremendous less resources to move. I agree with what has been said about root & rom options: CM7 on the EVO 3D will likely result in unprecedented (real world) benchmarks .Also note that the current Android releases are not yet optimized for dual/quad core management. But rest assured, it is well under development and the Sprint EVO 4G4D (hypothetical name) will behold a treasure trove of menacing capabilities.
HTC + Qualcomm + Android = Future
I think we should just wait until we can do a head-to-head AOSP CM 7 benchmark/real world test to see what happens. I'm confident the SGSII will get shredded by the E3D.
It seems unfair to compare anything within the phone itself now, because of what each phone has to run. Sense is pretty tasking on our phones and I can't say as much for the opposition.
It's funny to see NVIDIA make snide comments about Qualcomm when their phones are getting bested. Although I must say it is impressive to see that Tegra 2 phones are over a year old and keeping up with the E3D's dual-core deliciousness.
Just my thoughts.
Personally I don't believe Nvidia, plenty of benchmarks contradict their statement. That and whoever said "Additionally, the operating systems like Android and many apps aren’t set up for an asynchronous architecture." is an idiot because 99% of apps in the market don't support dual core lmfao.

Being that there are currently no EGL libs for anything except PowerVR SGX devices under ICS yet, and they're closed source and tightly dependent on the kernel there doesn't seem to be a huge point until the official updates start to hit for a range of devices.
Sure, Desire, HD, X10, N1 have ports of a sort at the moment, in fact there shouldn't be too many problems getting them working aside from the graphics drivers but they're just for fun with the framebuffer driver given how much of ICS' UI rendering is done with GPU acceleration in mind. You wouldn't want to use it day-to-day. The browser is surprisingly responsive on the Desire though (I'd say moreso than GB, despite the software rendering), as is the Market (the new one always lagged really badly for me on the Desire before) - glimmers of hope for ICS' eventual performance on older devices. The keyboard lags like you wouldn't believe though!
The Atrix should fly under 4.0.1 though, if it ever happens - bearing in mind the fact that the SGX 540 in the Galaxy Nexus is pretty much in a dead heat with Tegra 2's GPU, we've got a lower resolution screen, and can overclock past the its stock speeds.

So EGL = gpu driver? If thats the only setback, would it be possible to get an ICS rom with software rendering as a proof of concept, or are there other pieces missing?
GB/CM7 is pretty good on the Atrix, if we dont see ICS for a few months it doesn't hurt us in any way. I'd like to think most of us can be patient if we lack the skills to help.
I noticed the Captivate got a port of it too since i9000 ROMs and Cap ROMs are interchangeable. I thought its funny that it's running on the HD a Windows Mobile 6.5 phone lol. Let's all try to be patient and we will eventually see it.
Edit: not to mention I'm sure if it's not already it will soon be on iPhone too. It seems like iPhones always get the new Android versions kinda early. I'm not sweating it I love my Atrix in its current state.
According to anandtech, Tegra 2 support is essentially ready, so I think as long as nvidia releases the source for ics (libs?), someone will try to port it. Hell, I have a good 5 weeks during break, I might as well try then.

Actually, no, despite being a much older GPU, the SGX 540 found in the GNexus outpaces the Tegra 2 due to its higher clock rate by 7% or 45% depending on the GLBenchmark being run. Both GPU tests were done at 720p resolution. Also, you can't overclock the GPU, only the CPU.

Depends on the benchmark, yes - texture-heavy rendering tends to perform better on the 540 in the OMAP4460 thanks to it's dual channel memory controller and high clock (and that's probably the directly relevant part to UI rendering to be honest, though as I said - lower resolution screen ) but the Tegra 2 is quite substantially ahead in geometry-heavy rendering (and games on mobiles are starting to move that way now, following the desktop landscape over the past 5 years or so.) Averaged out, the performance of the two is very close.
Plus, as I said, the GPU in my phone is running at 400MHz which ought to even things out in the GLMark 720p tests somewhat even if they are biassed to one architecture or the other. While the GPU in OMAP4460 may overclock just as well from its stock 400MHz, I'm only really concerned that the phone can run as fast as a stock GNexus to maybe skip the next generation of mobile hardware and tide it over until Cortex A15-based SoCs on 28nm process start to emerge with stronger GPUs. I don't really think I'm CPU performance bound with a 1.4GHz dual-core A9 - and increasing the number of equivalent cores without a really substantial boost in GPU horesepower seems worthless right now, even if ICS takes better advantage of SMP (re: Disappointing early Tegra 3 benchmarks - although it does seem GLMark stacks the odds against NVidia GPUs more than other benchmarks?)

I would expect the Tegra to beat a nearly 5 year old GPU, but it only does so in triangle throughput. Tegra just uses a very poor architecture in general. Look at how little actual horsepower it can pull. The Tegra 3 gpu pulls 7.2GFLOPs @300mhz. The iPad GPU and the upcoming Adreno 225 both pull 19.2 GFLOPS at that same clockspeed. I honestly have no idea what the engineers are thinking over atNnvidia. It's almost as bad as AMD's latest bulldozer offerings. It's really more of Tegra's shortcomings than GLMark stacking the odds. PowerVR's offerings from 2007 are keeping up with a chip that debuted in 2010/2011. The Geforce just doesn't seem to scale very well at all on mobile platforms. But yea, all Nvidia did with Tegra 3 was slap in 2 extra cores, clocked them higher, threw in the sorely missed NEON instruction set, increased the SIMDs on the GPU by 50% (8 to 12), and then tacked on a 5th hidden core to help save power. Tegra 3 stayed with the 40nm process whereas every other SoC is dropping down to 28nm with some bringing in a brand new architecture as well.

I think you are not seeing the whole picture...
The Tegra 3 (Et-Al) is not just about its quad core implementation, remember that the GPU will offer 12 cores that will translate in performance not seeing as of yet on any other platform.
Benchmarks don't tell the whole story! Specially those benchmarking tools which are not Tegra 3 optimized yet.

LOL I ran all the iDroid ports on my iphone. Not one was even in alpha stage, I would not even count iDroid as a port since you cant use anything on it.
I'm curious as to the importance of CPU vs GPU in our phones. The two big processors from MWC were Qualcomm's S4 and Nvidia's Tegra 3. From my research, it seems like the S4 has a better CPU but Tegra 3 wins in graphical processing.
Is the speed of android usually limited by CPU or GPU?
Which one would be more important in apps like web browser and games?
Is it worth it to wait for Cortex A15 processors this fall, or is that much speed just overkill?
I'd saymthe CPU is more important, since there's phones out there that don't have a GPU and because pre-honeycomb, the GPU was mostly used for minor rendering and inside games.

Moving to Q&A
The gpu is a graphics proccesor unit, it is that which processes the graphic information displayed on the screen, having one of these takes the responsibility away from the CPU leaving it to do the other things it needs to do.
Having a gpu on a phone I don't think is really that nessasary yet as we are not doing anything that intensive with our phones graphicaly, who's doing cadcam or 3D rendering or graphic animation or anything else like that on a phone? However as time goes on and phones get used more and more then a gpu will be a must...
just look at the PC world say 20. Years ago we were using Hercules 2 tone graphics cards, then 4 tone cga wow then 16 tone ega then omg 256 colour vga. Then started the 3d era when a really fantastic gpu was a must in stepped the voodoo 3d graphics.....
Anyway I could go on for hours I think u might get the idea..
Sorry for long post
sent from my legend, currently using extream legend fuse™
I'd say both: CPU and GPU are equally important, to allow for super smooth UI experience AND some decent gaming.
So now we have Tegra 3 (A9 + nice GPU) and Qualcomm S4 Krait (A15 + average GPU), both being great.
If you want to wait, there will be Tegra 4 coming out next year, S4 Pro (quadcore + more powerful GPU) and not forget the TI OMAP5.
I usually go buy whatever there is best at the moment and I enjoy new hardware while waiting for new stuff to come out. The waiting for better stuff will never end as new devices are coming out every few months, so up to you how often do you want to upgrade.
Hi all Ive seen a few people mention game boosting apps and have found a number of paid and free options but am wondering what people here are using (if any) ?

Hi there,
I (probablu) ran into the same problem as you did: whilst playing demanding games (like GTA 3/Vicy City) the device stutters and is having difficulty producing a smooth framerate. On an HTC Sense rom whilst playing GTA:VC I had like 13 FPS @ low settings (18% draw distance, 70% screen resolution, medium GFX settings and dynamic shadows OFF) and it was just awful. Then I decided to put CM10 on my device. In the settings menu there is an option called 'Performance' and you can change the profile there. The default profile is 'ondemand' but I changed it to 'performance' to let the quad-cores work at full capacity. Now, all of a sudden, I can run GTA:VC on the highest settings possible at a steady 30+ FPS.
If tl;dr: don't bother with 'game boosters', they will just terminate proccesses running in the background. Instead flash your device with a nice ROM: CM10. It has A) better battery life because there are no unnecessary processes running in the background and B) overall better performance due to the fact there is no SENSE interfering.
Just my two cents.
http://forum.xda-developers.com/showthread.php?t=1783260
Actually this app is no joke and was made specifically for the one x, with this app you will achieve greater performance than with cm10 or forcing the performance governor which will just overheat your phone, the tegra 3 processor couples the gpu to the cpu, for example when the game uses only two cpus the gpu is limited to half speed which is why gameloft games lag, gaming boost decouples the gpu, optimizes the cpu governor and sets the minfrees to aggressive so that the game receives enough ram to maintain a stable framerate.

The HOX+ is not based on another version of tegra. It's just a newer revision of the same chip in the HOX.

First off you must be rooted, and before you go complaining about lag, battery life, poor gaming performance, etc, have a look on the internet because chances are you either have a faulty device or someone has already created a fix. Many new phone manufacturers will market their device as quad or even octa core, tricking the market into believing that smooth gaming and UI are a result of having a 1.7ghz quad core or such when in reality the chip pushing the pixels is the GPU, probably the most important factor in a chipset which gets likewise upgraded every generation but is not advertised as heavily as the CPU.
So why the lag?
The Tegra 3 CPU is linked to the GPU, therefore, the GPU will only scale up to its maximum frequency if the CPU has activated multiple cores and is running at a high clock speed, however to save battery life the Tegra 3 prefers to use 1 core. This is why most Gameloft games lag (as they only use 1 core). Fortunately there is a fix, you can allow the GPU to scale dynamically by using the attached init.d script, if it doesn`t work, try using smanager, setting it to run on boot with su access. This will allow the phone to weight its processing more on the gpu, allowing the power hungry 40nm CPU to scale down to a lower clock, hence saving power. If you get stuttering in the UI make sure you flash a custom rom and enable the GPU 2d rendering or GPU UI rendering option in aroma.
Why won`t my phone scale to 1.7ghz all the time?/Why does my phone only use a single core when clearly more power is needed?
The Tegra 3 is also not a 1.7ghz quad core per say, the processor can only scale to 1.7ghz when using a single core. This is buggy as sometimes the processor will get stuck in single core and cause lag and unnecessary battery drain if the frequency scales too high in order to multitask. To fix this, head over to Nik3r`s thread and flash his elite kernel, hxore is also great however it does not include blades commits (however the removal of hotplug will give similar effects). These blade kernel implementations will allow the phone to use all four cores at 1.7ghz, dramatically assisting multithreaded applications and games that are cpu intensive but poorly optimized.

My Launcher is constantly reloading/Heavy open world games lag/Sense multitasking sucks!
Elite also features swap memory, although I cannot recommend it for daily use, if you are a heavy gamer, it will help in any unity or unreal engine game and also stops the launcher from reloading which can be annoying (sense is a ram hog). These come in various sizes which from 128mb to 256mb and performance gains really depend on usage or what you think is necessary.
Performance is great but battery life is terrible
You might also want to try UV your phone,again poses some risk but cannot cause permanent damage like the aforementioned swap memory, before doing so check you tegra 3 chip variant. These range from 1-4 with the original One X being 1-3 and the One X+ being mainly 4, 3 if you are unlucky, the higher the better and faster/cooler. You can check by using a terminal emulator and typing:
cat /sys/kernel/debug/t3_variant
I personally own a variant 4 which operates well even with a 100 millivolt UV, however as all devices are different you will have to experiment with this. This option will keep heat down and save power as the tegra 3 has plenty of CPU to spare. I will also provide multiple UV Scripts for you to try out (stock elite is -25 millivolts). I also recommend using the phone in powersave when not gaming, the majority of games will probably run well even in powersave (limited to 1.15ghz and 3 cores).
Display uses the most power/auto-brightness scales too high or low/I just want to turn my button backlights off
You can also use a brilliant app called Lumos to manage screen brightness (the bright SLCD 2 screen does have its drawbacks) and backlight brightness or you can copy the lowest brightness apk from insertcoin v 3.2.1.

Update 1: New scripts!, seemed to have fixed a problem regarding the gpu failing to decouple, could explain why people were seeing no improvement. Custom folder if you want to tailor your device`s performance to your specific needs/rom/kernel, standard, just contains scripts that should provide a sizable performance gain for all devices.
How do I use this script? Flash it?
Thanks for the explanation!

First off you must be rooted, and before you go complaining about lag, battery life, poor gaming performance, etc, have a look on the internet because chances are you either have a faulty device or someone has already created a fix. Many new phone manufacturers will market their device as quad or even octa core, tricking the market into believing that smooth gaming and UI are a result of having a 1.7ghz quad core or such when in reality the chip pushing the pixels is the GPU, probably the most important factor in a chipset which gets likewise upgraded every generation but is not advertised as heavily as the CPU.
So why the lag?
The Tegra 3 CPU is linked to the GPU, therefore, the GPU will only scale up to its maximum frequency if the CPU has activated multiple cores and is running at a high clock speed, however to save battery life the Tegra 3 prefers to use 1 core. This is why most Gameloft games lag (as they only use 1 core). Fortunately there is a fix, you can allow the GPU to scale dynamically by using the attached init.d script, if it doesn`t work, try using smanager, setting it to run on boot with su access. This will allow the phone to weight its processing more on the gpu, allowing the power hungry 40nm CPU to scale down to a lower clock, hence saving power. If you get stuttering in the UI make sure you flash a custom rom and enable the GPU 2d rendering or GPU UI rendering option in aroma.
Why won`t my phone scale to 1.7ghz all the time?/Why does my phone only use a single core when clearly more power is needed?
The Tegra 3 is also not a 1.7ghz quad core per say, the processor can only scale to 1.7ghz when using a single core. This is buggy as sometimes the processor will get stuck in single core and cause lag and unnecessary battery drain if the frequency scales too high in order to multitask. To fix this, head over to Nik3r`s thread and flash his elite kernel, hxore is also great however it does not include blades commits (however the removal of hotplug will give similar effects). These blade kernel implementations will allow the phone to use all four cores at 1.7ghz, dramatically assisting multithreaded applications and games that are cpu intensive but poorly optimized. To enable this use attached script.

Place them in etc/init.d folder and set permissions to rwxrwxrwx using root explorer or run on boot using scriptmanager.

I don't see a folder in etc called init.d, am I supposed to create a folder and name it init.d?

Thanks for the wonderful effort.
As I am using the interactive optimized script, I encountered a problem at:
/sys/devices/gr3d/enable_3d_scaling
It said it cannot find such folder.
My phone spec:
- ARHD 6.5
- Elite kernel, latest one
Thanks
I really don't want to ask a dump question but there are a lot of files in the rar. I use Elegancia 5.2 with custom kernel, AT&T, so what is the file(s) suitable for me.
Pls give me a clue. Thks

Decide by yourself which scripts fit your needs. You will most likely want to use decoupled gpu and try different io schedulers. For 1.7ghz quad and uv I'm not sure if they will work on att . Which kernel do you use?
Whatdo you want to achieve?

THX for that. I tried two scripts with ChaOS and it feels snappier

Hello everyone I'm trying to decide between S3 and HOX+ and the only thing that seems to be better in S3 is gaming performance. Can I play Modern Combat 4, Asphalt 7, and NFS:MW smoothly on this phone? Do these scripts fix Gameloft lag?

I still do experience lags with the international one x+ on games like canabalt and most of 3D games are unplayable (sonic 4 ep II THD for example).
I'm on AOSP+ with Blade kernel, GPU scalling doesn't change a lot... I've tried supercharger V6, very smooth but not in games as well...
Any ultimate solution?
Thanks ryan, after using a couple of your scripts, combined with a much larger VM Heap. My phone feels like it should of out of the box For some reason tapatalk won't let me thank your OP. So i thanked post 3 lol

You`ll want to look into a custom kernel as all use the smartmax governor which has better batterylife than ondemand and use cpuquiet driver which switches cores easier, ie uses less power, generates less heat as cores are clocked lower but more are active. Try the undervolt script but use a less aggressive one if you experience crashing or lag.

What function do the UV (50/75/100) scripts and the sio sheduler have
Sent from my One X+ using xda premium
UV is undervolting. In this case each frequency step is undervolted by 50/75/100 MV which will help to keep your device cooler and thus saves batery and prevents thermal throtteling but also might cause instability. For the i/o sheudlers ask google, its to complex for one small post. But in a nutshell it determines in what order tasks are handled.
