I was wondering this today too. In all probability the iPhone 5 will be running the same CPU/GPU as the iPad 2, which will probably be the dual core A5 chip with a PowerVR SGX543 (perhaps in dual configuration). Last year the Samsung used the same chip as the iPhone 4 but a PowerVR SGX540 instead of the iPhone 4's SGX535 so it was a bit more powerful.
This year it's a bit different since Samsung has decided to go with the ARM Mali (in some sort of multicore setup) which no one has any experience with really. Maybe apple has bought so much of samsung's chip that it left none for samsung themselves to actually use in their galaxy 2 lol.

Just my opinion.
Probably NVIDIA due to their expertise in the graphics sector.

From the preliminary data I've seen, Tegra 2 is a bit faster, significantly so with Flash vector rendering (though that's likely just because Flash hasn't been optimized for the Mali-400). It's looking like the Mali-400 is 10%-25% slower than Tegra 2, assuming the test data I've seen is based on a dual-core Mali-400 setup, which I'm reasonably certain it is.

There was even a blog where they ran a Quadrant and FPS test on LG Optimux 2x, Motorola Atrix and Samsung Galaxy S 2 - The overall winner was LG as its bearing the Tegra 2 along with Gingerbread; whereas Motorola Atrix is Tegra 2 with Froyo.

Confirmed: Tegra 2-equipped Samsung Galaxy S II is coming http://engt.co/gEVbgv

Wow... that's interesting. It's kind of a bummer knowing that the iPad2/iPhone5 hardware will be better than the Tegra2 phone/tablets...
Edit: Also just saw this on Engadget - http://www.engadget.com/2011/03/03/imagination-technologies-powervr-sgx543mp2-really-is-faster-be/
With the SGX543 being 4x faster than the Nexus's SGX540, and the SGX540 being on par with Tegra 2's GeForce ULV GPU, all these Tegra 2 devices will be getting outdated quite fast =\

Actually a Tegra 2 Galaxy S II pretty much has piqued my enthusiasm for it. I know in raw numbers a Quad Core Mali 400 looks to run circles around a Tegra 2. But Tegra 2 is the reference platform for Android 3.0 (and possibly 2.4 which looks to combine the tablet and phone platforms). In all probability, Android will be optimized for Tegra II and Mali 400 might not outperform it at all. PLaying the same game on a HTC Desire HD with the ADreno 205 and a Galaxy S with the PowerVR SGX 540 shows no discernable difference at all. So the extra horsepower is pretty much not utilized unless the app is optimized for it.

Really... what games specifically? I've tried games on my MT4G and my Vibrant/Nexus S and they ALWAYS ran smoother and faster on the hummingbird. Jet car stunts, asphault 5, dungeon defenders, reckless racing, etc... and in all graphics benchmarks adreno 205 loses to the SGX540.

Looks like samsung's chip might actually be quite capable.

Practically the same games. I found hardly any difference. Apart from Hero of Sparta and some scenes in Skies of Glory with many planes, they both are pretty much on par as to what i've seen. Of course the Hummingbird is faster overall that is not in doubt. I just meant the difference is not very "discernable"

Mali for the win
i was getting pretty bummed out mali 400 but them i saw the odroid-a benchmark numbers on gl-benchmark( the odroid-A has the exynos). Since glbenchmark is so dependent on resolution you can scale up the scores to see what it would be at ipad res.

Mali 400 trumps tegra 2 do a little research

Next Nexus = Exynos version of SGS2 with sexy ID. Same as what they did with the SGS and NS. I would be happy with that.

Exynos much better than tegra.
tegra not optimaze for android....
exynos running like a Rambo !
and all benchmarks telling the same

CMON just compare on GLBenchmark and would be fine...
I do not believe what I see.... Mali400 more powerfull than Tegra2, and TWO times more powerfull???? YOURE KIDDING ME?
Amazing... Nvidia go awai noob...

......1 SEC MAN !
I like sgs2 ! but one think! we "CANT" say WHO is BETTER !!!!! until !!!...until real Gingerbread gonna come for G2X !!!!!!!!
Than we gonna SEE who is faster !
2.2 VS 2.3 ?
morfic kernels 1.5 Ghz on g2x (tegra2) killing by scores results galaxy s2 1.5ghz. But lets wait 2.3 after I will tell u tegra2 or exynos
BEST REGARDS !

yes, i agreed with you, i doesn't clearly fair enough to compete because sgs 2 using gingerbread and o2x still froyo....

ive been following this thread for a while now and i have to put an end to all this bull**** you lot are saying.
2.3 is not like what 2.2 was to 2.1. 2.2 was a huge speed boost compared to 2.1 with the arrival of jit. but 2.3 is not a HUGE speed boost. I believe there are some improvements in 3d graphics but not that much.
the reason why you havent seem major graphics improvement on existing games on the mali 400 sgs2 is that the games arent OPTIMISED for it. Devs like gameloft havent got around to making games with super high detail to run on the sgs2's new hardware
Tegra 2 however is different. in games like dun def you can clearly see a distinct difference in graphics with tegra 2's version looking like the pc/console version of the game and the non-tegra version (THIS INCLUDES THE MALI 400) looking much worse but still great.
all you lot have been saying that the mali 400 is better because its faster. WRONG. Raw speed isn't everything, you need apps and games to use those resources properly.
so while the tegra 2 gpu is slower than the mali 400, it has far more content made for it. I dont see the mali 400 getting much dev love in the future since the only branded device ive seen using a mali gpu
Ill tell you lot what i tell my friends who thinks sgs2 is king. gaming wise the sgs2 is NOT a dual core beast (i know technically it is dual core). It just runs the single games with no extra eye candy, it just runs it really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really really fast.

[Q] RAM

Do you think 512MB RAM are enough for the Optimus 3D? And what kind of RAM has the SGS2 for example? Is it ddr1? And is it a big difference with ddr2 ram in the optimus 3d compared with other new smartphones?
The first time i red that the optimus 3d only has 512 mb of ram i thougt this isn't enough for a new smartphone but all i heard till now sounds really good. so what do you think?

+1, also, is 512mb enough to play resource heavy games? (note - i don't necessarily mean 3d games, just lets say the version of dungeon defenders or NOVA thats out in 6 or whenever months time) I don't know much about how much ram games use, all i know is you cant add any more ram to the phone (or any phone for that matter)
Thanks
Ian

it's absolutely enough!!!and it's also dualchannel ram so very fast.

And do you know what kind of ram other highend smartphones have? like the SGS2? And can you compare the ram in smartphones with the ram in pc: ddr2 in the optimus 3d = ddr2 in my pc?

Optimus 3D uses a dual-channel LPDDR2 memory controller. search on google and wikipedia

I know what the Optimus 3D has. I just can't find something for the Galaxy S2 and others ^^

Ah ok i found it. It's also DDR2

Its only fast until you run out of it, filling up 512mb of ram is pretty easy.

Thats what i was afraid of.

Me too and i'm really thinking about changing my order and buy a SGS2. I really prefer the design of the Optimus 3D and the SGS2 would be more than 100 € more expensive for me than the Optimus 3D. But the ram and the camera are two things that are much better on the SGS2. And there is much more activity on the SGS2 board on xda ... i'm not sure but at the moment i think the SGS2 is the better choice!?

512mb are absolutely enough,don't talk without sense do you want to install Crysis?than 512mb are not enough.

I know that it is enough for the next 6 months, maybe for the next year, but are you sure it is enough for new stuff afterwords? and did you compare the videos and pictures of sgs2 and optimus 3d? sry but the quality of the 3d is very bad compared with the sgs2. really don't get me wrong, i would prefer the lg not only because of the much better design, but those are two major things that can't be changed :/
and did you see latest gl benchmarks? why is the sgs2 that much better in the egypt test?

yes all.
You are talking about a pre-production model of Optimus 3D,so you have to wait the final rom.
The gs2 is very powerful but it have:
-gingerbread
-1.2ghz cpu(was 1.0ghz but samsung noticed that wasn't powerful as optimus 3d,so has overclocked it to 1.2ghz)
-final rom
so to compare the two device we have to:
wait 2.3.3 for the 3D,wait the final rom,overlock to 1.2ghz...then compare.

but i think this won't change anything with the quality of the camera.

buy a digital camera

[Q] Ram required for HD GAMES for android phon

Hi guys, I'm new in this forum and gonna buy a new android phone in next months,
LG optimus 2x and Samsung Galaxy S2 come in mind.
After spec and prices comparison, LG O2X seem not bad,
but something hold me back which is the unstable froyo 2.2 where I hear a lots of problems occur and the 512mb ram.
It was said the 128ram is dedicated for GPU of Tegra2,
so 512mb - 128mb = 384mb,
then after some ram for UI and OS,
What I remember I saw from other webs states left around 220-200mb.
So i wonder while playing HD games for android such as assassin creed, GTA and others, normally how much ram will inccur?
Sources I read through from GSM, Anandtech and others.

Dual channel ram? What does this actually mean for us

Okay so our phones apparently have dual channel ram honestly. Idk what this means for us Ik we have 512mb does this mean 2 512mb sticks actually adding up to 1gig or does it mean 2 256mb sharing processes also what does it do please any answers would be nice I moved from the sensation and I like this phone it seems faster than it or the evo 3d

Dual channel increases the max bandwidth of memory by using 2 channels instead of one, we probably have 2 256 mb chips, each one with his own channel.
It should help in bandwidth intensive scenarios (gaming for example)

thanks simple and exactly what I wanted

Im an ITT graduate for computer forensics. In this age part of my learning was to forensically examine all smartphones as well since they are just as capable in hiding data as computers are. Dual channel means 2 channels of memory as opposed to one to increase bandwidth just as mentioned above. Part of the reason computers are getting faster and gaming smoother is because of increased RAM channels and video cards increasing in GPU Cores and memory lanes or channels, this applies to phones. I actually have one , LG Thrill 4G or AKA Optimus 3D and tested it with a benchmark against some of the newest devices the Galaxy S3 and Galaxy Note 2 both with quad core processors and single channel RAM. My results are as follows:
Optimus 3D: 1856.4 Mbp/s
Galaxy S3: 821.66 Mbp/s
Note 2: 849.39 Mbp/s
As you can see the note and s3 have same memory architecture and practically tested the same the difference was probably in the amount of apps running in background. The LG tested more than double the speed and it only had about 270mb of free RAM at time of test as opposed to the 1300+ mb or 1.3gb or RAM free on note and galaxy. Faster RAM means more responsive gaming and smoother graphics. Now the processor of the thrill 4g is ages behind so its almost unfair to compare app launching and phone reboot to the other devices I have but even the processor difference the RAM tests speak for themselves. Devices in similar time as the Optimus wont even come close to gaming and video playback because the faster the memory the more you can process and more efficiently as well. I'm sure that there is a game or two out there that would run better on the LG than even some of today's phones its just a matter of searching and testing.
I am quite honestly puzzled at why that was the only phone with dual channel RAM, I would have expected today's quad core devices to utilize this architecture and result in much faster smoother running phones with astonishing overclocking results.

Thaaaaaaaaanks for this answer! !!
But I have a question .. in overclocking is that damage the CPU ??? and the same question about the tempreture?? and what the overclocking actually do ?? Why did not lg overclock thier phones ??

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.
