Mali-400 MP is a GPU (Graphics Processing Unit) developed by ARM in 2008. Mali-400 MP supports a wide range of use from mobile user interfaces to smartbooks, HDTV and mobile gaming. Adreno 220 is a GPU developed by Qualcomm in 2011 and it is a component of the MSM8260 / MSM8660 SoC (System-on-Chip) powering the upcoming HTC EVO 3D, HTC Pyramid and Palm’s TouchPad tablets.
Mali™-400 MP
Mali™-400 MP is the world’s first OpenGL ES 2.0 conformant multi-core GPU. It provides support for vector graphics through OpenVG 1.1 and 3D graphics through OpenGL ES 1.1 and 2.0, thus provides a complete graphics acceleration platform based on open standards. Mali-400 MP is scalable from 1 to 4 cores. It also provides the AMBA® AXI interface industry standard, which makes the integration of Mali-400 MP into SoC designs straight-forward. This also provides a well-defined interface for connecting Mali-400 MP to other bus architectures. Further, Mali-400 MP has a fully programmable architecture that provides high performance support for both shader-based and fixed-function graphics APIs. Mali-400 MP has a single driver stack for all multi-core configurations, which simplifies application porting, system integration and maintenance. Features provided by Mali-400 MP includes advanced tile-based deferred rendering and local buffering of intermediate pixel states that reduces memory bandwidth overhead and power consumption, efficient alpha blending of multiple layers in hardware and Full Scene Anti-Aliasing (FSAA) using rotated grid multi sampling that improves the graphics quality and performance.
Adreno 220
In 2011 Qualcomm introduced Adreno 220 GPU and it is a component of their MSM8260 /MSM8660 SoC. Adreno 220 supports console-quality 3D graphics and high-end effects such as vertex skinning, full-screen post-processing shader effects, dynamic lighting with full-screen alpha blending, real-time cloth simulation, advanced shader effects like dynamic shadows, god rays, bump mapping, reflections, etc and 3D animated textures. Adreno 220 GPU also claims that it can process 88 million triangles per second and offers twice the processing power of its predecessor Adreno 205. Further, Adreno 220 GPU claims to boost the performance up to a level that is competitive with console gaming systems. Also, Adreno 220 GPU will allow running games, UI, navigation apps and web browser in largest display sizes with lowest power levels.
Difference Between The Two
Difference between Mali-400MP GPU and Adreno 220 GPU
Based on a research done by Qualcomm using an average of Industry benchmarks composed of Neocore, GLBenchmark, 3DMM and Nenamark, they claim that Adreno 220 GPU in Qualcomm’s dual-core Snapdragon MSM8660 offers twice the performance of the GPU in other leading dual-core ARM9-based chips. Also, a team known as Anandtech has done several tests on Adreno 220 GPU. One of them was the GLBenchmark 2.0, which records the performance of OpenGL ES 2.0 compatible devices such as Mali™-400 MP using two long suites that include a combination of different effects such as direct lighting, bump, environment, radiance mapping, soft shadows, texture based on the use of vertex shader, deferred multi-pass rendering, texture noise, etc. and the test showed that Adreno 220 GPU was 2.2 times faster than the other existing devices such as Mali-400 MP GPU.
What do you guys think of this??.... I've been with HTC since they started doing Android... and I have to say android has come along way and so has the hardware....
thanks
thanks, i'be been looking for feedback regarding adreno 220 vs mali 400 GPUs, do you have any link or source to back this up
I am looking forward to buying the sensation, and my only concern is the adreno 220 GPU as and whether it is better, equal, or workse than the Mali 400
If it is better then i'm definitely buying the sensation, if not then i might consider the galaxy s II
Thanks
interesting read... the sgs2 fans will debate this and say that the benchmarks were done with an over clocked processor.. so as of now its all just a good read
i don't know if this video helps but the gpu upscaling and running on a larger screen with higher resolution and not falling back is kind of amazing

Isn't it Adreno 205 ?
http://www.gsmarena.com/sony_ericsson_xperia_play-3608.php
Adreno 220 is faster than Mali-400MP anyday, and compared to Tegra 2 it's better in some cases and worst in others. I didn't get a Galaxy S2 due to the fact that the Mali-400MP is soo antiquetted...
According to reports on the SGS 2 forum, the Mali 400 doesn't support textures? This seems a big blow on the SGS 2's gaming capabilities to me. What would be an interesting comparison would be the Adreno 220 vs the (LG Optimus 3D's) OMAP4 PowerVR SGX400 GPU, which is clocked at 300MHz instead of the 200MHz found in the samsung hummingbird processor....

It does support texture compression, just not the proprietary formats of other GPU vendors. Developers that only code for proprietary formats get locked in and lose out when something better comes along.
i surely was waiting for an idiot response like yours i9100 just face it that samsung made a mistake with the mali... and to be quite honest with you the sgs2 was rushed out to take the lead on the market b4 the sensation.. and the cpu was overclocked to be more competitive with the sensation... and the rush has shown what i expected lots of unknown problems in the phone and then returns for phones with faulty screens and so on so dont be a troll and state facts rather than just talk because you have the device
Mail 400 is just an outdated chip, why someone wouldn't include texture compression in a MOBILE gpu is beyond me. What the hell were they thinking?!! The PS3 only does this because it has a blu-ray sized storage media! Ridiculous.
As stated, it DOES support texture compression. There are just a few formats and it only supports one of those. It won't prove a problem as it seems the SGS2 is going to be extremely popular and all game devs will support it eventually (most do already)

I wouldn't be surprised if that was the case. To Samsung, that's business as usual.
I'm biased and this is not the Samsung home turf so I'll just keep to correcting facts. A little flaming is fine and not unexpected, but I won't go there. I'm enjoying my phone, and you should enjoy yours ;-)
In OpenGL ES 2.0 there is only one standard texture compression format - ETC. It's the only one you can rely on in all conformant GPUs. Others like ATITC, PVRTC and S3TC/DXTC are proprietary formats not suitable if you want your app to run on new devices.
at the moment since my hd2 has been retired i opted to buy a samsung galaxy s 4g worst mistake i have made in a long time... bought a sidekick 4g for my gf and that phone was another example of how poor quality control if for samsung or how they rush to get a head start in the market... the phone is riddled with problems

lol its not as bad as what i have read in the sgs2 forum where people are reporting their problems and trying to get legitimate help and are being bashed and called trolls because their phone honestly has a problem
now the question is why sammy choose arm than powervr ?
arm dont have experience with gpu
The SGX540 is not more powerful than the Mali-400MP4. Where did you get that from?
And as for ARM and the Mali-400 being their first consumer GPU, it's pretty damn fine for what it is. It beats out most other competition and the perf/mm² is great for Samsung. What'll prove them is going to be the next Mali-T604 which should by the paper specs, kick some ass.
I prefer "truths" that are backed up with DATA. Otherwise, you're no better than the local town drunk shouting about end of days on a street corner.
It steel my opinion
in the benchmark mali-400 are not all time on top
and powervr gpu have more compatibility game

first I think you dont have importante things to do
seconde i now my english is not good as your
Well if one's looking at purely triangles and texture formats then SGX540 > Mali400.
But SGX543MP2 > both anyway.
I don't think the sgx540 is better than the mali but i don't have any proof either. But the sgx543 indefinitely better than anything out by atleast twice their power. Wonder how bad it will heat up though...

Yep, indeed. Taken directly from that article: Given current workloads, ARM's Mali-400 is clearly the fastest GPU available on a smartphone today.
Now that its official, I'm really concerned the ipad2/4S will get special super graphical editions of games.
While Mali400 is fast, its mostly represented by 1 phone. The level of graphics in the rest of android phones is much further down.

Then obviously you don't have a clue about what Chainfire3D is,eh?Not to mention that most games now support the Galaxy S II without hacks,except for a handful or less.
Anyway,you all are missing an important fact here.GPU clocks.Let me explain:
The GeForce ULP in the Tegra 2 is clocked at 333Mhz.The SGX540 in the OMAP 4460(or whatever version the SoC of the Galaxy Nexus/Droid Razr is) is clocked at 384MHz.The Mali MP-400 is clocked at only 267Mhz,as is Qualcomm's Adreno 220 in HTC's dual-cores.So,it's fact that the Mali MP-400 and the Adreno 220 are significantly handicapped here(Although we don't know the clock of iPad 2's SGX543MP2),especially the Adreno 220 which is included only on qHD screen phones till now.
I can give you GLBenchmark results of my Galaxy S II,with my GPU running at 400MHz.It smokes every mobile device,except for the iPhone 4S and iPad 2(Let's face it,the SGX543MP2 is a beast,but the SII is also some 6 months older),although it significantly closes the gap in performance.
So,if you still think that the SGX540 is better than the Mali MP-400,I'm sorry but you're a moron.Maybe the Adreno 220 is.Maybe it's not,but it's the only GPU in an Android smartphone that even comes close.Get over it,seriously.They all play all of the Market's games without breaking a sweat.
how did you get the Galaxy S II's GPU to 400MHz? how stable is it? and how stable is your cpu at 1.6Ghz? and is the 1.6Ghz OC on the cpu with the GPU OC to 400mHz? and what is your battery drain like with all this OCing going on?

The phone will feel like hot lava while playing games like MC3 and the thing will drain the battery like a bulimic vampire. Expect like 60 minutes of MC3 online before the phone dies, unless it catches fire turning your hands into hot burgers even before that happens

Huh,funny.I might disappoint you but no,it's not bad at all.Battery is draining really bad when screen is too bright.As long as screen brightness is low,battery doesn't drain that fast.Also,the phone doesn't get hot with most games,except for some reaaaaally ****tily coded ones.And the coding doesn't even need to suck in general,only the "Galaxy S II" part if you get me.I played ShadowGun with 16x MSAA for hours without overheating problems.Yet Asphalt 6 managed to make it almost burn,even with 1200MHz CPU and 200MHz GPU.Go figure.

The component thats bugging me a lot is the GPU. I am seeing old Adreno 200 GPUs on new phones like the Desire V.
#1-So is it really a factor that affects the overall performance of the phone?
#2-And which is the best?
I have seen phones equipped with Mali 400MP,Adreno 200,205,220 and 225,SGX 540...and those Tegra chips from LG Optimus Series.
Which one is the best?
#3-And the phone on my mind is Desire X(will be released soon),and many pages say that it comes with an Adreno 203 chip.Now whats Adreno 203?
And hows its performance?

GPU's are not the biggest factor no, as long as the CPU and RAM is enough overall performance will not be effected by the GPU.
Some games that are very 3D intensive would befit from a more powerful GPU yes, and for some games the Tegra 3 chip allows for better shading and water effects etc
thanks zac
GPU are saparated ram allocated for gaming..
More the gpu better the gaming performance...
It means 400mali is better than 200 adreno..
Other thing gpu does not effects over all performance but it effects clarity of graphics and display visualiTy...
So in 250 eur.
I Think galaxy S2 is good choice..
Good processor
Good gpu
Good screen resolution..

larger ram can make your phone work smoother(except games).

Actually its both . RAM also has a major impact on games. The better the GPU, the lower the impact on the RAM since the device won't need to be put under too much "strain" to process the graphics (also requiring a good CPU).
GPU IS IMPORTANT FOR SMOOTH OS PERFORMANCE. The current OS uses GPU acceleration to smooth things out ig. ICS and JB. Many ROMS also enable GPU to increase performance throughout the OS. If you have a snapdragon, then it uses RAM from the phone for RAM on the GPU where as Tegra has it's own dedicated RAM for its GPU.

The no. in the card's name does not reflect the ram it has.It reflects the model number.And of course the Mali mp-400 is better than the Adreno 200.It performs better than the Tegra 2.
Here's the performance order of previous generation chips :
Mali Mp-400>PowerVR SGX 540>Adreno 205 >> Tegra 2.
Maybe the Adreno 205 isn't THAT much better than the Tegra 2,but the Tegra 2 is highly over-rated,and the Mali mp-400 pulls cleanly ahead of it.

Yes, it does have a GPU. It has an Adreno 200.
You know, I have been using for some time a(pretty old by now) LG Optimus One. It has an Adreno 200 GPU and an ARMv6 600 Mhz CPU.
Even if I overclock it to 800Mhz and maximize the ROM performance in every way possible, GTA3 for example runs pretty much non-playable(very low FPS).
The Optimus One uses a Qualcomm MSM7227 SoC(2009). But in 2011 Qualcomm released the MSM7227A(used for example in Galaxy Mini 2) which also has an Adreno 200 for GPU, but it uses a much better ARMv7 800Mhz Cortex-A5 CPU. The GPU coupled with this much more capable CPU handles GTA 3 really good, playable without problems.
That's really interesting to me, to say the least. It's like you would have a good video card in your PC, but it was bottlenecked by the CPU. And Adreno 200 is quite old.

It has an enhanced Adreno 200.That's how it gets better graphics score in AnTuTu.And I'm surprised you can't run GTA3.I can play Dead Space no lag on my Wildfire S,even at stock,and that looks just as intensive as GTA3.
Although I do agree the CPU might be a bottleneck,it shouldn't affect 3D gaming.The UI becomes really smooth @ 825Mhz,which surprises me as it lags in comparison at even 806Mhz.
Dead Space also runs very good on Optimus One, GTA 3 is much more demanding.
It has to do with the fact that GTA is an open world game which requires more background processing rather than current processing that the majority of android games use. I believe that the CPU does the background processing which is why it lags. This also explains why the galaxy mini can play GTA while having a similar clocked CPU, the architecture.

512 dual channel RAM
PoweVR SGX540 (GPU)
i saw a video on youtube show pes2013 on galaxy s2 with fps 60
i think psp processor 333MHz and that's lower than dual core 1 GHz
The problem is the RAM. Also, MIPS is one ugly RISC processor, hence PS2 emulator have to be run on a personal supercomputer (four core 64-bit x86 CPU - either Phenom II or Core i7, GeForce 9800 / Radeon HD 4670 and 2GB RAM being the minimum), so it's one of the reason why it doesn't end pretty. And you will have to continuously tweak the plugins to achieve the best rate (I had to do so on my PC for a week to get 50+ fps on PS2 emulator on my PC).
EDIT: 333MHz MIPS CPU clock is correct, and there is 32MB DDR II memory in it - I am going to shoot for 533 MHz clock (266 MHz base FSB clock). Yet, it doesn't help anything a bit - I suspect PSP CPU is a superscalar in-order MIPS-6000 (?) processor, quite similar to 299 MHz Emotion Engine (custom superscalar MIPS CPU) inside the PS2, so that requires four threads out of superscalar pipelines, and a superscalar vector FPU.

Google it.
You don't know how Playstation systems work.
The hardware there is a little bit different.
MIPS is an ISA for the specific processor, and RISC = Reduced Instruction Set Computing, basically a simple processor, determined only by the registers inside the CPU's on-die cache RAMs. Your phone have a RISC processor also - ARM (Advanced RISC Machine).
The reason I said MIPS is ugly is because it have few oddball registers which usually break the Floating-Point expectation in other processors (Phenom II is based on PowerPC-like RISC engine but still), so they have to work significantly more than once just to get it right. Also, RAM is still a problem - I know of Sony's rather strange habit of using surprisingly little RAM memory: They used modified version of compcache, basically compressing the entire game instructions into small RAM vector slices.
And why is the RAM a problem? You guess it: MIPS virtual machine eats lot of memory that PS2 emulator eats 400 MB just to run the game on my PC, at decent framerate. Now granted, PSP is basically a portable version of PS2. And Galaxy S II have 1 GB RAM - I know because I have Captivate Glide, basically a S II with built-in keyboard (need to get new screen).

Also, RAM is still a problem - I know of Sony's rather strange habit of using surprisingly little RAM memory: They used modified version of compcache, basically compressing the entire game instructions into small RAM vector slices.
And why is the RAM a problem? You guess it: MIPS virtual machine eats lot of memory that PS2 emulator eats 400 MB just to run the game on my PC, at decent framerate. Now granted, PSP is basically a portable version of PS2. And Galaxy S II have 1 GB RAM - I know because I have Captivate Glide, basically a S II with built-in keyboard (need to get new screen).

In a few words, game developers make their games to use the best of the Playstation systems, that way changing the whole way of running the game so it will run perfectly on the Playstation systems. This leading to incompatibility with our normal hardware, and the actual emulation requires lots of RAM. Remember you are emulating the whole Playstation system you don't have the hardware parts that will run the game at as it will run on the Playstation systems.
I think I am right, if not Dr. Mario please, correct me.
Yes, that's correct. Not to mention you have to remember PS2 and PSP both have in-order processor, basically straddling along with the time-slice kernel in the BIOS and the entire firmware both unless replaced with what's on the disc. Time-keeping is just tricky on out-of-order processors, thankfully they have special register counters inside them, which the emulator uses.
EDIT: The usage of strange but rather special RTOS complicates matter in emulated virtual machine a bit - what if you time the entire symphony of processor threads wrong? A lot of strange things will happen: 1. It will simply do nothing (even more likely) 2. You won't be able to play games. 3. You get weird graphic glitches (ditto for #1). 4. You fry your TV or the PS2 (a lot less likely) / your phone (possible - if it freezes, better turn it off quickly). To get correct framerate, you have to time the vector threads against the out-of-order processor's operating frequency, to be divided down to the real clock of MIPS VM - 3 GHz : 10 = 300 MHz for Phenom II / 1 GHz : 3 = 333 MHz for ARM Cortex A9 and to keep it in order (Vector FPU seems to be the special case - why didn't Sony think of that? VUs can execute out-of-order, it just have to crunch numbers independent of CPU threads).

thnx anyway guys
although i don't understand most of Dr.Mario words
it seems that you are a programmer to understand these things
Yeah, and hardware designer (electrical engineer to be precise) too, so I basically have good concept of how that works.

I found the GPU clocked into six stalls 533_480_420_350_266_177_100 ( path :/ sys / devices / platform)
But playing the game , the real operating frequency is 420mhz or 350mhz. Difficult to stay in the 480mhz. Or even higher 533Mhz never run before.
Samsung officially praised the memory, CPU frequency in order to meet the growth , Exynos 5420 also enhance the memory speed from the dual-channel LPDDR3 800 upgrade to a dual-channel LPDDR3e 933. However, in my opinion , Samsung did not do . Bus frequency is at 800 , I think Samsung's sincerity is not enough.
mali-T628 and adreno330 running Epic Citadel ( Unreal Engine 3 ) when , T628 's performance as Adreno330. Tests are run in Ultra High Quality.
Mainly in the T628 in the face of the sun dips occur when the number of frames , the minimum number of frames 20 appears . Final score is 47 .
But adreno330 has this capability, minimum 40 full frames , the final score is 55 .
I do not know the problem is not there in the T628 's GPU drivers
Finally, I hope the emergence of a great God to do the 5420 kernel.
@ AndreiLux hope you can do the 5420 kernel. Perseus because your kernel , overclocking GPU and CPU was perfect. GalaxyS4 9500 has been concerned about your kernel , this is my Samsung Exynos persistent reason, because you have been looking forward to coming back to do Exynos kernel.:good:
