1GHz pda cpu :) - General Topics

http://www.xbitlabs.com/news/mobile/display/20050824041008.html
finaly we can get doom3 running on our pda's well maybe we also need
SLI with some ATI or nvidia pda graphics chips but ...

yep mhz increase is significant but as I read processing power will be better in only ~25%

Which are all the Phones with - 1 GHz Qualcomm CPU ?
& which is Best of them all ?

wah, you even bring back a 2005 post about 1ghz cpu haha..
and since intel already have monahans chips out that can go up to 1ghz and even sold to marvell now, they have pxA930 tavor new chip which can run higher than 1ghz.
but xscale chip are not widely used now due to price. hence now we only get most of the pda with qualcomm chip
we have to get a snapdragon device and do a benchmark with intel monahans and tavor first
qualcomm video driver is always a problem to everyone holding onto HTC devices playback dvd resolution.
so far comparsion with intel xscale & qualcomm qtv driver, intel is still the winner.

thank you

msm7200 520mhz vs. xscale 800mhz?

Is there much of difference beside clock speed. from the msm7200 in the touch pro 2 and the xscale running at 800mhz in the omnia II in terms of performance? ANy help would be appreciated.
If you ask me it (should) make quite a difference. The msm7200 is quite notorious for it's quite allright clockspeed but slow performance.
I used to have a Diamond (with 528 mhz) and then got a Omnia (Marvell 624 mhz) which was already quite a difference. I guess the 800 mhz will make even more of a difference.
Do note that there is a big difference in resolution between the Diamond and the Omnia, so that will also give some speed increase. The Omnia II has a Samsung 800 mhz chip (as far as I know) and I don't know what kind of performance that will give.
Both cpu's are a ARMv6 (afaik), so in that perspective you could say the 800 mhz is faster than the 528 mhz.
See this:
Samsung chip: http://pdadb.net/index.php?m=cpu&id=a6410&c=samsung_s3c6410
Qualcomm chip: http://pdadb.net/index.php?m=cpu&id=a7200a&c=qualcomm_msm7200a
My old diamond was much slower than my current ipaq 211. The ipaq has a 624mhz marvell and is much faster and more responsive than the diamond. It can also play videos back much better. 800mhz would just increase the performance gap.
The Omnia II is Arm11 which is slightly faster than the iphone 3G(both get blown out of the water by the 3Gs), and should support OpenGL ES 2.0.
Here's Samsungs Data sheet on it: http://www.samsung.com/global/syste.../2008/5/30/785500s3c6410_datasheet_200804.pdf
The msm7200, i BELIEVE(dont quote me), would be faster than the SC36410, if it had proper drivers.. however, thats not the case.
numbers are an indicator and nothing more. They give you a clue but clues can be very misleading. If they were usefull, why would you need benchmarking?
http://en.wikipedia.org/wiki/Megahertz_myth
(yeah i know wiki is sometimes full of BS but it certainly backs up what I learned in Uni and during my assembler cracking/virus writing days)
The ONLY way to compare CPU's is to run the same application and then run the SAME task in that application. Once you have done so ALL you can say is "For performing task X in application Y, processor ZXY running operating system ABC is faster on the BLAHBLAH platform" and nothing more. It does not mean its faster at everything or indeed, you cannot say its faster than ANYTHING else until you have tested it.
At the end of the day, the processor is affected by drivers, processor design and the operating system and its installaition.
and Software.. if theres no apps that incorporates acceleration, then its wasted.
what about qualcomm 1G snapdragon cpu?
how fast is that compares to current 528mzh? haha
i'm waiting for Acer S200 with 1G cpu.

please re-read and if you still don't understand, i'll try and explain again.
clearly, marvell is better, even the mhz is lesser than what qualcomm offers!
having better decoders also like video playback & multitasking when video is playing!
waiting for devices with marvell cpu pxa168 series.
they use qualcomm chip becoz its cheaper & provide hsdpa to network & GPS module while the rest does not come with it. so individual chip must be used. but its better like GPSone VS SiRF III

Tegra or Snapdragon

Hi everybody, I just have some questions.
I plan to change my HTC Hermes next year but I don't know which based-device will be the best...
Snapdragon or Tegra.
Tegra seems to have 8core of execution for great graphics but not a big frequency(600-800Mhz). Snapdragon got the Ghz and is supposed to reach 1.3Ghz in 2010. There is also a dual core snapdragon 2x1.5Ghz supposed to be available this year but will it be for smartphones?
These are the questions I have because a PDA is a lot of money for me and I wanna choose the right device...
Thanks
Well snapdragon is multi core SoC just like Tegra but what nvidia is so proud of is power island. It means that they can shut off unneeded module(ex. turn off all modules except of modem when in standby). Tegra uses ARM11 CPU where snapdragon is based on improved cortex A8 besides it is clocked at 1Ghz so tegra can't win this one. GPU is better on tegra and probably video performance is better too but when it comes to brute force snapdragon wins hands down.
I think that is all you need to know about tegra and snapdragon. About that 2x1,5Ghz snapdragon it is designed to be used on smartbooks. It would be an overkill for smartphone at least for now.
Thanks that's all I wanted to know
also a Mhz is not just a Mhz
first of all a qualcomm mhz could mean more or less performance boots then a OMAP mhz
not to mention it don't really matter if the cpu is super fast if the ram and storage and other IO of a device can't keep up

Tegra is just like the Snapdragon a SoC. If we use the same logic that Nvidia used, then the Snapdragon is also a multi core SoC ( CPU, GPU, DSP, ... ). But its just marketing to make it look to people that they get a 8 Cpu system
Like Wishmaster89 pointed out, there is a major difference between the CPU's used on both system.
The 600Mhz Arm11 ( ArmV6 ) on the Tegra is capable off executing, about 1/3th what the Snapdragon's ArmV7 1Ghz Cpu can do.
The GPU on the other hand, is more powerful in the Tegra. There is a little list being used to compare the overall ( theoretical ) strengths off each platform's GPU
Nintendo DS: 120,000 triangles/s, 30 M pixels/s
PowerVR MBX-Lite (iPhone 3G): 1 M triangles/s, 100 M pixels/s
Samsung S3C6410 (Omnia II): 4 M triangles/s, 125.6 M pixels/s
ATI Imageon (Qualcomm MSM72xx): 4 M triangles/s, 133 M pixels/s
PowerVR SGX 530 (Palm Pre): 14 M triangles/s, ___ M pixels/s
ATI Imageon Z430 (Toshiba TG01): 22 M triangles/s, 133 M pixels/s
PowerVR SGX 535 (iPhone 3GS): 28 M triangles/s, 400 M pixels/s
Sony PSP: 33 M triangles/s, 664 M pixels/s
PowerVR SGX 540 (TI OMAP4): 35 M triangles/s, 1000 M pixels/s
Nvidia Tegra APX2500 (Zune HD): 40 M triangles/s, 600 M pixels/s
ATI Imageon _ (Qualcomm QSD8672): 80 M triangles/s, >500 M pixels/s

So, the Tegra's GPU is about twice as powerful as the Snapdragon's ATI Z430 ( looking at Triangles ). The reason why i use the term theoretically is because a lot off factors can make or break a GPU ( many more then on a CPU ). Bad drivers, bandwidth limitations, to little memory, bad mix off texture units, vertex units etc..
Problem with Nvidia is, they have always had the habit off exaggerating things ( a lesson learned more then a few times in the past ).
Another problem is, are the GPU's actually being used on the PDA/Smartphone's? A lesson i learned in the past from the x50v, with its own dedicated powerful ( in that time ) 2700g ( 800.000 Triangles in that time ). The reality is, most applications rely the most on the CPU.
At best, if you have dedicated games, written for the PDA/Smartphone market, very few will tap in to all the power that the Tegra has to offer.
Even the PSX Emulators ( who run great ( full speed 50/60fps pal/ntsc games ) ) on the Snapdragon. Forget about running a lot off psx games on a Arm11 without tweaking ( and frame skipping ). Because it relies the most on brute force cpu power ( and this is where the Snapdragon shines ).
So? What is there besides games? Video playback? Sure... The Tegra can supposedly do 1080p, while the TI OMAP & Snapdragon's only do 720p. But from what i have read, its more to the DSP that does the work. The snapdragon's DSP runs at 600Mhz, i don't find any information about the Tegra's DSP? Does it even have any? Anybody with more info how they even handle things?
When it comes down to PDA/Smartphone's... take it from me. The most important thing is first the CPU. Then the amount off memory ( and memory speed ). Then the GPU.
Lets just say i like to see a fair comparison between both systems, to see there real power ( and not some nvidia fake PR where a lot off people still fall in ).
Like i said, i don't exactly trust Nvidia's numbers when there PR posts crap like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Those numbers are what you can call a pure lie. When people from the OpenPandora project ( what uses a TI Omap3630 @ 600Mhz, with a slower GPU ), is able to run quake3 at 35+ fps... Yet, Nvidia claims 5fps for the Snapdragon, thats actually more powerful then the TI Imap3630... I love those little [*] next to the text... Small text below: "* NVIDIA estimates". In other words, how much trust can somebody place in the specs from a company that that pulls stunts like that.
Also... Snapdragon is used in the following smartphones that i know off: Toshiba TG01, Asus F1 ( S200 ), HTC HD2 ( Leo ), and a few more that are on the way. Where is the Tegra? The MS Zune... Thats it...
You think that HTC, Toshiba, Asus will all have looked at the different available SOC providers ( TI, qualcomm, Samsung, Nvidia etc ). Yet ... Who do they pick for there new top off the line products...
I hope this helps...
OP, therw isn't much to add after all that expert info, but I can make it easy for you. SD = raw power, Tegra = fancy graphics. I prefer power, because of the better overall performance.
as i see it the tegra chip has 2 600mhz cores + 6 other cores to do video, audio etc.
so a 1ghz snapdragon would have to split it mhz to deal with any audio, video etc whilst the tegra chip would have separate cores dealing with this stuff leaving 2 600mhz cores free.
this would make tegra a lot faster than snapdragon.
one thing which would be interesting would be batt life
in various situations
and excluding the atom as it's not really a phone cpu
one thing of note is that every snapdragon phone, although seems fast still has the standard wm lag at times (probably more wm that the cpu).
whilst the zune hd looks super smooth and very fast.
we will have to wait for the first tegra wm phone to see if it has the wm lag as its hard to tell by comparing a mp3/4 player (which has a os which was probably made from the ground up to run on the chip) to a phone.

You're completely wrong! As I said both are multi core SoC's. Both snapdragon and tegra have separate cores for video and audio! The only difference is that tegra can shut off unneeded module where snapdragon can't. Besides they know that their CPU is slow so they have to give people something that will make them forget about CPU so they decided that talking about 8 cores on something as small as their SoC would be a good choice.
As I said before raw CPU power of snapdragon is at least 3x greater than tegra and zune HD is smoother because all the work is done on the GPU(besides the whole Zune OS 4.0 was probably designed on tegra so don't expect it to lag) where WM is only CPU driven. Besides wait for HTC Leo to see almost lag free device(show me device that never lags).
For the last time. For know tegra has slow CPU where Snapdragon has a beast for CPU. Things should change with tegra2 and snapdragon2.

*uch* So much misinformation... I may not be a expert, but you just claimed that the Snapdragon needs to split its mhz, to do ... video? Did you even read that snapdragon's specs. Dedicated ... GPU. GPU = Video!
Another wrong point, is that both cores are not at 600Mhz. One core is at 600Mhz, and one Core is at 400Mhz. The 600Mhz core is a ARM11 core, and the 400Mhz, is a Arm7 core ( not to be confused with the ArmV7 aka Cortex A8 ).
The basic idea is, when a phone is in standby, that the 400Mhz Arm 7 core, does the basic staying alive stuff. Where as the 600 Arm11 core, is only used for the big stuff. The basic idea is good.
But, the Snapdragon 1Ghz ArmV7 Cpu is able to downscale, and reduce its power footprint also. What solution is the better one ... We will needs to see.
To put things in perspective:
Tegra:
* ARM 11
* ARM 7
* GPU
* 2D Engine
* HD Video Encoder
* HD Video Decoder
* Audio
* Imaging
Snapdragon
* ARM v7 ( Cortex A8 )
* GPU
* DSP
* HD Video Decoder
* ...
Now... You will say. Hey, look at all those extra cores that the Tegra has. Must be a power house... No ... It does not work like that.
The Snapdragon's 600Mhz DSP has several capabilities, including dedicated Image processing, etc. The question is, how fast is the Image processor for the Tegra? If its a separate core, it has its own frequency. This alone make a big difference, because the slow that core, the longer it takes to do the job ( and the more power drain ).
The 600Mhz Tegra that we are comparing here, has only a 720p output capability. Just like the Snapdragon. As far as i can tell, the Tegra 600 is used in the Zune. Something tells me that the Tegra 650 is more for notebooks.
HD Encoding / HD decoding. By any definition, that is part off the GPU. Just like the ATI Z430 has its own dedicated HD capabilities. And any GPU these days has the ability to disable part off its to save power. So we can assume that the same capability is in the mobile variant. The Z430 is based on the GPU found in the x360. It has its own HD, audio, media, etc processing capabilites ( aka, if you like to call it in Nvidia's term... HD, Audio, Media Core's ).
So, from a technical point of view, the Snapdragon has also 8 cores. Hell, we can trump that, because the DSP is capable off more then just Image processing. So, how many extra cores can be gain from that?
To be honest, there is so much misinformation that people jump on... Its actually kinda incredible ( and frightening )... While i need to admit, when looking at the Google links, Nvidia did a good job at spreading the FUBAR information. Most sites took over the information, without questioning it one little bit...
Lag?
And Ganondolf regarding the lag that you report? To be honest, i have shown several movies to a friend with WM6.5 + Touchflow backported on older HTC devices ( devices with the same slow cpu's, like the Tegra uses ). Guess what... Beyond a bit off lag on the Image viewer, they had no lag.
Take a look at the Video's off the HTC HD2 ( Snapdragon ) ... And find the lag there please...
I have seen a few people like you before on other forum's, going around all high & mighty about the Tegra. At first i was impressed by its general specs. Until you start to look deeper, and discover that the CPU is slow as hell ( and the second one is even worse ) compared to the Snapdragon / Cortex A8 / ArmV7 design. That the "extra" cores, are just functionality provided from the GPU. And that its 1080p claim, does not come from the version now used.
In fact, Snapdragon also has 1080p capability. See the QSD8672. But you will not find that SmartPhone's just yet. Just like the Tegra 650 with its 1080p. Has anybody even seen a Tegra 650 on the market? I don't think so ( for good reason ). Looks like another Paper launch from Nvidia.
Simply put:
As of July, 2009 or Oct 2009 for that matter:
Snapdragon mobile phones = shipping.
Tegra mobile phones = vapourware. (not even any firm rumours)

the lag i was talking about was on the toshiba tg01 which i have played with. there is no point saying look at videos of the htc hd2 as i saw vids of the tg01 which looked like it was lag free, till the hd2 comes out and i have a play i (we) wont be able to tell if its lag free or not. as i can see u are making your argument about lag on a phone that has not been released which i think is a rubbish argument, as someone could say a tegra phone could teleport you across the world (there is no proof).
Also im not on the tegra bandwagon as i like snapdragon just as much, i was going by what i had heard on the net. maybe like you said information has been made to look like the tegra chip is super powerful compared to all the other phone cpu's, what is not true but till i see a phone with a tegra chip in it how would we know?

By far the most important point.
Far more important than the MHz number which may or may not even indicate greater or lesser performance or battery life than a competitor with an entirely different architecture.
There is one piece of info that I haven't been able to find. Which one of the two has better performance when it comes to battery power usage?
Anyone?
Tegra is right on the ball.
Yes, the ARM11 cpu is theoretically 1/3 the speed of the Cortex but don't forget there's an ARM7 offloading network traffic, 2D acceleration separate from the CPU and GPU, dedicated HD encoding hardware (decoding is common on both) and sound acceleration. Many of the processing bottlenecks in a mobile device are successfully offloaded in the tegra, ultimately giving the ARM11 less tasks to cope with in the first place, and no need for thread balancing which, fingers crossed, leads to more stable os performance. Another thing to note is that nVidia's official specs say ARM11 MPCore, which means that various tegra chips could have anywhere from 1 to 4 ARM11 cores (the tegra chipset used in the Microsoft Zune player was a duel-core ARM11).
The main point though I think is the power. You don't need a massive CPU in a mobile device, what you need is battery life, which although we haven't received final figures, the tegra is looking infinitely more impressive than anything else on the market. If my iPhone 3GS is anything to go off even x2 the battery life would be welcome, this thing dies in no time at all be it browsing the web, playing video or music; reviews show snapdragon phones to be even worse than this. The nVidia specs regarding battery in earlier posts are mostly accurate but based on a netbook battery. The Zune HD running the tegra has 33hours of audio, 8.5 hours of video, however uses only a 660mAh battery; this is half the size of the battery on the iPhone 3GS and HTC Touch HD2 for example.
The tegra GPU is a powerful CUDA based design and will allow for GPGPU acceleration of the only major computationally intensive task that phones are likely to do in the future which is image processing for augmented reality.
They've provided on-chip support for most modern input/output devices.
nVidia have covered all the bases, I'm seriously looking forward to tegra phones.
Yes, but as I've learned (the hard way) from my Touch Pro, all the features in the world mean nothing if they're not used. Touch Pro was supposed to have video acceleration and double the speed of my old Tytn. Where are those? Nowhere. Why? Some say "there aren't any drivers for the GPU", others say that TPs processor may be 500MHz, but its design is worse than the one in my older Tytn...
I don't care. As a customer, user and buyer, I know that my older phone was faster than my new one. If in the near future we have a Snapdragon 1GHz phone that does everything in its CPU and a Tegra phone that ballances cpu-gpu-physics-whatever in different parts of its design, history says that the Snapdragon will be the better choice. You see, WM Solitaire, Word Mobile, RSS Readers, Twitter clients and all existing software, at least for WM, is written to run on a single processor. I've yet to see a good program/game that will actually take advantage of any devices GPU - and that won't happen while the market is split, for a developer would need to create his program for a specific device (meaning less profit) or simply forego any acceleration and create something "that runs anywhere". We can thank Microsoft for going the Linux way and advocating device makers doing whatever they want, whichever way they want, without some standard way of using different hardware parts (like, say, DirectX in Windows).
very interesting informations.
Battery life is really important, that's at the moment the only advantage of the Tegra vs SN.
I am really keen to know if Manila works also fast with less CPU-Power of the Tegra-Chip as the Leo.
There must be some driver or software problem I would say - because there's no PDA out with the Tegra.
Also no announcement... otherwhise it could be also a strategy from HTC that they didn't get a problem in selling the Leo and oncoming Android-device.
So we must w8...
I think you guys should see PGR on the Zune HD.
Stunning graphics.
For me the processor speed will come 2nd place to functionality. I have recently started to use the remote desktop on my HD, but wish it had a TV out like my Touch Pro.
I was thinking about upgrading to a Leo but that has no TV also.
Discussing advanced graphics for a Snapdragon is not helpful if you are restricted to 4 inches.
Hopefully HTC will put HDMI or at least video out on all future devices. The resolution of the devices is upto it, so why not.

TI OMAP 3630 vs Qualcomm Snapdragon

Having a droid, I have dug into the details of TI's omap platform and I heard that the Xtreme will have the 3630. I am very impressed with the whole omapzoom.org and the platform itself. I am not at all familiar with the Qualcomm offerings. Anyone up for discussing the differences between these two platforms to include the advantages and disadvantages of each?
Cheers, jdeclue
TI Omap is based on the arm-cortex A8 tech which is supposedly to be more efficient and fast. Qualcomm has a long history of bad graphics support. The GPU is horrible. Well, its not exactly that bad but the drivers that are provided for the use for Qualcomm's GPU is often inadequate and hence underperforming. Sure the snapdragon is a whole lot better than the previous qualcomm SOCs (i.e. msm72xx series). But I feel that the reason for it is due to the higher clockspeed. The 1ghz speed tends to help with the peformance. But for me personally i would prefer the TI OMAP simply because it is a cortexA8 core which is better performing and the much better GPU.
So in a nutshell,
Qualcomm Snapdragon clockspeed maybe higher than the OMAP but the performance wise is comparatively close.
BUT however the OMAP GPU is better than Snapdragon.
With the ongoing increasingly graphically intensive trend, i think the way to go is with TI's OMAP. (Or untill qualcomm releases the 1.5ghz dual core snapdragon, then i would consider it )
There. That's my take.

Our Next Phone...

Looking back, when I switch phones it is usually when there is a better device out with a significant improvement over my current device. My first smartphone was the Tmobile MDA (HTC Wizard), which I bought roughly 5 years ago. The next phone was the Tmobile Wing (HTC Atlas), with a much smaller form factor and faster CPU the device was a great improvement.
My next device was my first real HTC marketed phone, the Touch Diamond. The diamond, was a complete overhaul from the other two HTC phones I used. I loved every little part of it. But going from the Diamond to the glamorous HD2 was even more amazing, the screen, the size everything was perfect.
Now the question I have is that it is almost a year that the HD2 has been out and I ready to get a new phone, but I am wondering about what things I should consider.
I dont think that the Droid X, or the Galaxy S smart phones are really all that much better than the HD2, so I am more interested in the Cortex-A9 phones that are slowly trickling into the market.
The CPUs that will have Cortex-A9 dual core tech are as follows:
Nvidia
Tegra 2
1Ghz
Custom High Profile Graphics
(Motorola Olympus, LG Star)
Qaulcomm
Snapdragon 3rd Gen
1.2GHz/1.5GHz
Adreno 220
Verizon HTC Phone
Samsung
Orion
1GHz
Mali 400
(Nexus S)
Texas Instruments
OMAP 4
1GHz+
PowerVR SGX 540
(Pandaboard)
Marvell
Armada 628
1.5GHz + Custom 624MHz DSP
Custom High Profile Graphics
ST-Erricson
U8500
1.2GHz
Mali 400
So basically what should I do? Wait for all of them to come out and then decide, or get which one comes first.
I want the best processing power with the greatest graphics, and was thinking on Tegra 2 but found that Open GL ES benchmarks have low values for the Tergra2 platform lower than the SGX 540.
Galaxy Tab Results:
http://www.glbenchmark.com/phonedetails.jsp?D=Samsung GT-P1000 Galaxy Tab&benchmark=glpro11
Folio 100:
http://www.glbenchmark.com/phonedetails.jsp?D=Toshiba Folio 100&benchmark=glpro11
Are these a result of poor drivers or is Tegra really weaker than the SGX 540, (and thus weaker than the Mali 400)?????
Is the Nexus S a better choice than the Motorola Olympus, or should I wait for HTC's addition to the game with a 3rd gen Snappy. Will the adreno 220 GPU out power the Tegra 2 and Mali 400. What do you guys think, and what do you plan on doing.
Well firstly better hardware means nothing if the software is the bottleneck. Secondly, we've seen often the grunt of the cpu is more contributive to performance of programs than the gpu in Android OS. Thirdly, you're going to have to wait, see, buy, test these platforms to know which ones are superior... but here is what I've discovered during the course of 2010.
SoC's for 2011:
(listed in what I believe is the best to the worse)
+ ARM Sparrow: Dual-core Cortex A9 @2.00GHz (on 32nm die), unspecified GPU
+ TI OMAP 4440: Dual-core Cortex A9 @1.5GHz, SGX 540 (90M t/s)
+ Apple A5 (iPad2): Dual-core Cortex A9 @0.9GHz, SGX 543MP2 (130M-150M t/s)
+ Qualcomm MSM8660 (Gen IV Snapdragon): Dual-core Cortex A9 @1.5GHz, Adreno 220 (88M t/s)
+ TI OMAP 4430: Dual-core Cortex A9 @1GHz, SGX 540 (90M t/s)
+ ST-Ericson U8500: Dual-core Cortex A9 @1.2GHz, ARM Mali 400 (50-80M t/s)
+ Samsung Orion: Dual-core Cortex A9 @1GHz, ARM Mali 400 (50-80M t/s)
+ Nvidia Tegra 2: Dual-core Cortex A9 @1GHz, nVidia ULP-GeForce (71M t/s)
+ Qualcomm Scorpion (Gen III Snapdragon): Dual-core Cortex A8 @1.2GHz, Adreno 220 (88M t/s)
Notes: The SGX530 is roughly half the speed as the SGX535. The SGX540 is twice as fast as the SGX535. The Adreno 205(41M tri/sec) is supposedly faster than the SGX535 but slower than the SGX540 (thus, is likely to be in the mid). The Adreno 220 is twice the speed of the Adreno 205 but it is slightly slower than SGX540(88M vs 90M tri/sec). Samsung claims ARM Mali 400 to be 5 times faster than its previous GPU (S3C6410 - 4M tri/sec), about on par (80M tri/sec) with the Adreno 220, but few leaks benchmarked it to be only slighlty faster than the SGX535 (40M tri/sec). The gpu used in the Nvidia Tegra2 has been quite contained (little known). I estimated the Tegra2 has 71M t/sec (Tegra 2 Neocore=27fps/55fps=Galaxy S Neocore, x62% disadvantage of screen resolution, x 90Mt/s of SGX540 = 71M t/s). And recently some inside rumors via fudzilla actually confirmed this exact figure, so therefore the gpu-chip inside the Tegra2 is roughly equivalent to the MALI 400.
All of these details are based on officially announced, rumors from trustworthy sources and logical estimations, so discrepancies can be existent.
Last thoughts: As you can see there is some diversity in the next-gen chips (soon to-be current-gen), where the top tier (OMAP 4440) is roughly 1.5 times more powerful than the low tier (Tegra 2). However drivers and software will play a lead-role in determining which device could squeeze out the most performance. And this factor may alone favour the iPad2, Playbook or even MeeGo tablets to be better than the Honeycomb tablets which are somewhat bottleneck-ed by the lack of hardware accelaration and post-transcription through the Dalvik VM. I think we've hit the point where we could have some really impressive high definition entertainment, and even emulating the Dreamcast at decent/fullspeed.
edit2: Well, Apple's been boasting over x9 the graphical performance over the original iPad. There are 2 articles on anadtech, one in Geekbench and a processor-specific details from imgtech (I dug up from 12months ago). It has been found that its a modified Cortex A9, 512MB RAM and the SGX543MP2. Everything points to the SGX543MP2 being significantly faster than the SGX540, and the given number was 133 Million Polygons per second (theoretical) for SGX543MP4 which is double SGX543MP2 performance. The practical figure is always less. Imgtech said the SGX540 is double the grunt of the SGX535, benchmarks show the SGX543MP2 is (on average) five times the grunt as the iPad (SGX535). So going by imgtech (the designer of sgx chips), the theoretical value that I list above, should be 70M t/s ... going by Apple's claim it should be 200M t/s ... going by benchmarks it should be roughly 130 M t/s. Imgtech's value is definently wrong since they claimed its faster than the SGX540 valued at 90M t/s. Apple's claim also seems biased, they take only the best possible conditions and exaggerate it even more. It seems to be somewhere in between, and wouldn't you know it, the average of the two "false" claims is equivalent to the benchmarked value
edit3: The benchmarks are out for the 4th-gen QSD, which confirms everything prior. It's competing for top place against the 4440 and A5. I've changed the post (only updated chip's name).
If one were to choose between the processor of the A5 and the OMAP4440, they'd be really pressed to choose between more cpu grunt or more gpu grunt.
Just re-edited the post.
Apple's A5 details are added in, its looks to be one of the best chips for the year.
If I had to choose between the OMAP4440 and A5, I probably would be reduced to a head-tail coin flip!
Update:
The benchmark results of the Snapdragon MSM8660 are in.... and it goes further to support the list.
MSM660 = Dualcore A9 + Adreno 220 + Qualcomm modification (for better/worse).

Which android gpu is the best?

1. Adreno
Adreno series ATI which is made​​, or used to be called ATI imageon series, circa 2002-2004 is at the beginning of the release of this GPU series. In 2008, AMD imageon sold to one of the leading manufacturers of processors, namely Quallcom. And now ATI / AMD only supportsthe architecture and development only. Now Adreno series is inherited from all the SOC (System On Chip) made Quallcom.
2. PowerVR
PowerVR Series is the first artificial logic video also enliven the VGA market, but as the dominance of NVIDIA and ATI video logic now only play in the world of mobile gadgets GPU. PowerVR itself is not in production in finished form by power logic, but they are only a draft architecture, which sold thelicense to many of the leading processor manufacturers such asNEC, Intel, Freescale, Texas Instruments and others.
PowerVR Series now in its sixth series, the second ever used in its game console in the 1900s, the Dream cast, and Sega Saturn. PowerVR SGX Series 5 is the series most often found on smartphones, SGX GPU 5 is an elite in the world of smartphones, the world might belike BMW cars.
3. Mali
Mali series, this GPU is made ​​in the ARM architecture, though still rarely heard his name, but its power can not be underestimated. Mali GPU series outstanding from HDTVs, gamingconsoles (PS3), up to a smartphone. Especially for smartphone, the series used is 400MP4 Mali (MP is the core indicators used). GPU is part of the SOC A9 1.2GHz Exynos dual-core CPU Samsung's Galaxy SII. Reportedly 400MP4 Mali is ableto render almost equivalent to the PS3 and Xbox 360.
4. GeForce ULP
Series GeForce ULP (Ultra Low Power) are concentrated in that part of the GPU Tegra 2 SOC manufactured by NVIDIA. GeforceULP uses quadcore 4 pixel shaders + 4 vertex shaders up to a total of 8 cores that are in it.
If for determining the performance of course can not be separated from what SOC is used, it is very difficult to determine the point which is used for comparison because each GPU is highly dependent on the performance and support of its SOC. For instance, SOC OMAP 4 series with SGX540 GPU vs quadcore Tegra 2 ULP GeForce GPU with 8core, hello who wouldwin? When to see the number of cores, by naked eyes 8core candidate who will be on the GeForce ULP but when calculating SOC capabilities then look OMAP 4 was able to bulldozeTegra 2, not only from the benchmark results, framerate, javascript rendering, but also within a matter of efficiency in the use battere .
This is not surprising because the OMAP 4 has a few secret weapons like supports dual channel DDR2 memory up to 1GB LP, where the new Tegra 2 is capable of using a single channel.Back again SOC capabilities greatly determine the outcome, as well as Snapdragon with its core scorpion, would be defeated perform with Tegra 2? Not really, mainly for multimedia results which force snapdragon and Adreno indeed in optimizingon this side.
i think andreno still the best one
andreno or mali :fingers-crossed:
guys I would like to go with Mali
If we're going to talk about actual numbers for actual GPUs that you can buy then this is what's available:
Adreno 320 (Snapdragon 600), Geforce ULP (Tegra3), PowerVR SGX 544MP3 (Exynos 5 quad), Mali T604 (Exynos 5 dual).
So far from what we know of 3DMark, GLBenchmark and some other tests, the approximate order of performance from best to worse is:
PowerVR, Adreno, Mali, Geforce.
This WILL change because of newer versions coming out (Tegra4 for example). For now though, I'd consider Adreno and PowerVR to be ahead, PowerVR for sheer performance and Adreno for a good balance between power, performance and die size.
ill go for mali
