I've only got my galaxy tab 10.1 for a week or so. It ran rather smoothly out of the box. But then it just slowed down. Now it frequently stutters when multitasking, screen rotating orientation, or even just running some applications. Things get particularly worse when live wallpaper is on. I checked in the setting/applications/running services to make sure I didn't run out of RAM (there was often still 300 something MB free).
Did any of you experience that? What would you suggest me doing to resolve this issue? Or is there no solution to this? I do remember everything running fine without lagging when I first used it.
Any sharing or suggestions are much appreciated.
None of the available tablets are capable of running live wallpapers smoothly. I don't have any problem otherwise though. Try doing a factory reset.
thanks. i probably should.
The Tegra 2 chip is not capable of running live wallpapers smoothly due to its crippled 32bit memory interface. It simply does not have enough memory bandwidth to process. Tegra 2 was SUPPOSED to have dual channel memory but Nvidia decided to ditch the second 32bit channel (which would have greatly improved performance under live wallpapers and games) to save power
This is the same reason why you notice your tablet slowing down after using it for a little while. Once system memory starts to get filled Android OS needs to shuffle around memory, remove apps from memory to make room for newly launched apps, ect. This all takes alot of memory bandwidth and with only a 32bit wide channel you can see why your tablet slows down. Especially when doing anything visual like swiping home screens across.
Most people dont know that Tegra 2 is an old chipset. Its been around for over a year now. I was blown away and shocked when I found that Nvidia used a crippled 32bit single channel memory interface. Not sure what they were thinking
I cant wait for TIs dual-core SoC, they run dual channel memory and have a GPU many times faster that Tegra 2. If you want to run live wallpapers its best to skip any Tegra 2 device and wait for a unit with TIs SoC later this summer or a Tegra 3 which will be in tablets in 5 months.
Many people feel their tablets and phones perform a lot better (at least when on the home screens) when you use a third-party launcher like ADW Launcher Ex or Launcher Pro.

third-party launcher will do nothing to improve performance and has absolutely nothing to do with live wallpapers or the performance of the unit.

I re flashed the tab 10.1 back to the 3.01 OS and It runs live wall papers great. No shuddering and my applications load quickly. I Do use android assistant and shut down any programs I don't use. Gonna try the new kernel.
so 3rd party launchers are bad... why? also, a new kernel for the tab? already?

3rd party launchers are just apps. There is nothing wrong with them but they certainly don't improve performance of any aspect of the device.
Any upcoming devices that will have the TI dual core cpu in it? Or will Tegra 3 be far superior by that time?

Archos is launching a tablet with the 1.5ghz TI dual core chip really soon. Itll be much faster than tegra 2 and have 3 times the gpu performance. The gpu performance on the tegra 2 is just plain awful even for a 1st gen device.
Thanks 5thElement for your detailed information. Now I have a much better understanding of how this problem came to be. For now though, I couldn't stand the lagging behind any more and reset the tab to factory setting. Smooth all around once again. Will have to re-purchase all the apps I paid for though. This part sucks!
Actually just found out u need not repurchase anything. Google sync remembers everything and does a full recovery of all settings and apps for u. Kudos to google!

They will indeed be more than likely faster than Tegra 2 but for the record the TI OMAP 4460 uses Imagination Technologies PowerVR SGX 540 GPUs which are the same GPUs used in the Samsung Galaxy S phones (not the new SIIs). That isnt a massive difference between Gefore ULP.
Now, the TIs OMAP 5 chipset does use a shock and awesome GPU that is dangerously similar to the iPads GPU which is from ITs PowerVR SGX 544 MP line and those are a true dual core GPU. Anandtech has some GPU benchmarks covering this....

The PowerVR 540 will be significantly faster than tegra 2 not only because it has a unified architecture but because TIs SoC will have dual channel memory unlike the crippled single channel memory the Tegra 2 has. The memory bandwidth on the tegra 2 is pathetic and it has to be shared with video which is seriously crippling for the Tegra 2 and its poor performance sticks out like a sore thumb as you can see when you try to run live wallpapers.

On MY Tab, Adw EX outperforms the stock launcher by leaps and bounds. I don't know what they did programatically, but it consistently moves smoother, faster than the stock launcher.
Live wallpapers are still problematic, but I do feel the presentation of icons/widgets is better. Not all launchers are created equal... including the default one.
I've just received the Galaxy Tab 10.1 and I already own a Galaxy S2 phone. I was very disappointed with the stutter and lag in the GT 10.1 compared to the GS2. In fact I was sort of amazed because I hadn't seen any reference to the poor video and livewallpaper performance when looking at reviews of the tab.
I've tried resetting to factory defaults after installing the latest firmware update from Samsung and I simply can't use a livewallpaper - the slowdown in performance of the tablet is quite noticable.
I've got videos on my GS2 that play fine but on the Galaxy Tab, they just stutter (and I'm not using a livewallpaper). I've tried all sorts of video player apps as well.
I wished I'd known that the Tegra 2 would not be capable of the sorts of things my GS2 is. It's just weird that I hadn't seen any reference to this before.
As suggested, try using a different launcher. While it doesn't change the hardware, most users find that the stock launcher is inherently laggy. ADW for example also has user adjustable tweaks which can improve perceived speed.
As for live wallpapers, some are worse than others of course. Experiment a bit. Also check widgets you may have on screen which could be causing slow downs. Things like circle launcher and updating social apps are known to cause slowness.
I am running Bonsai ROM with various tweaks, overclocked at 1.4gHz and can run live wallpapers smoothly with no problems.
Edit: You should also be able to run video smoothly. Using stock player or Rockplayer, etc. I regularly watch movies and videos, as well as Netflix with no issues. Of course video type, size, etc will make a difference, but even non-optimized movies seem smooth for me.

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.
Cheers!

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.
-The Tegra 3 SoC (System on a chip) is a combo of a microprocessor, a memory controller, an audio processor, a video encoder and a graphics renderer. It's designed and manufactured by Nvidia, world leader of graphics computing, making it's first appearance in the Asus Transformer Prime.
-The Tegra 3 SoC has 5 physical cores, but limited to performance of quad-cores. The 5th, lower power core, is activated only when the device is idle or handling low tasks, such as syncing and e-mail checking. So, power consumption is always kept to minimum when performance of the quad-core is not needed, ensuring longer battery life. Once you run a normal or higher-demanding task on the tablet, the 5th core shuts off automatically before the 4 main cores are activated. This is all the bios of the chip and doesn't require the user or the developer to change anything to use the Android OS and application this way. Android OS already has a the best support for multi-tasking and is multi-threaded friendly compared to competing operating systems in the market. So, this should be good news of the Asus Transformer Prime to-be users soon.
-The GPU (Graphics Processing Unit) in the Tegra 3 Soc has 12 shaders. But, because Nvidia has not followed a unified-shader architecture in this ARM SoC like they've been doing in their PC and MAC discrete graphics cards, 8 of those 12 shaders are reserved for pixel work and the remaining 4 are for vertex. Maybe Nvidia will use unified-shader architecture in the next generation Tegra SoC'es, when the ARM-based devices are ready for it. The PowerVR MP2 GPU in the iPad 2 has more raw power than the Tegra 3 GPU (Actually, it's the only one thing I personally like about the iPad 2, it's GPU!), but the Tegra 3 Geforce (the commercial name Nvidia uses for their gaming graphics processors) should give a solid 3D performance in games, especially the officially supported games. Nvidia has long history in 3D gaming and been using it's solid connections with game developers to bring higher quality gaming to Android, like what we've seen with Tegra 2 SoC capabilities in games listed in the TegraZone Android app. Add to that, games are not just GPU bound, Tegra 3's quad-cores and 1GB system RAM (iPad has 512MB) will pump up gaming qualities for sure and the pixel density of 149ppi displays crisper images than the 132ppi of the iPad 2. Once the Asus Prime is released, it can be officially considered the highest performing Android device in the world, especially 3D gaming.
Well, I thought I'd have more to type, I paused for a long time and could not think of anything to add. I only wanted to share few things I know about the Tegra 3. I have high interest in computer graphics/processors and been following the Tegra project since 2008.
Some of the Asus Prime to-be-owners doesn't know or care that much about technical details of the CPU in the device and I thought of sharing with them.
Thanks and gold luck.
Thanks for the info. Very interesting
As I understand it, the use of the lower power 5th core has decreased battery consumption by over 60% when compared to the earlier 2 core design. I am not sure how they are measuring consumption and the task load.
I am most exited about the tablet because of the tegra 3.
In smartphones I find the idea of putting more than one core quite rubbish.
It is not the best solution for a tablet or any other mobile device too. I would highly appreciate a well programmed software over overpowered hardware.
Yet the tegra has a nice concept.
I think most of the time I won't use more than that 5th core. I mean it is even powerful enough to play HD video.
I will primarily use apps that display text and images. Like the browser who is said to utilize 4 cores. But I am sure only because of the crappy programming.
So if people finally come to their minds and start optimizing their apps we will have one quite powerful core and 4 in backup for REAL needs. Seems like an investment in the future for me.

Straight from Wikipedia:
Tegra 3 (Kal-El) series
Processor: quad-core ARM Cortex-A9 MPCore, up to 1.4 GHz single-core mode and 1.3 GHz multi-core mode
12-Core Nvidia GPU with support for 3D stereo
Ultra low power GPU mode
40 nm process by TSMC
Video output up to 2560×1600
NEON vector instruction set
1080p MPEG-4 AVC/h.264 40 Mbps High-Profile, VC1-AP and DivX 5/6 video decode[18]
The Kal-El chip (CPU and GPU) is to be about 5 times faster than Tegra 2[19]
Estimated release date is now to be Q4 2011 for tablets and Q1 2012 for smartphones, after being set back from Nvidia's prior estimated release dates of Q2 2011,[20] then August 2011,[21] then October 2011[22]
The Tegra 3 is functionally a quad-core processor, but includes a fifth "companion" core. All cores are Cortex-A9s, but the companion core is manufactured with a special low power silicon process. This means it uses less power at low clock rates, but more at higher rates; hence it is limited to 500 MHz. There is also special logic to allow running state to be quickly transferred between the companion core and one of the normal cores. The goal is for a mobile phone or tablet to be able to power down all the normal cores and run on only the companion core, using comparatively little power, during standby mode or when otherwise using little CPU. According to Nvidia, this includes playing music or even video content.[23]
Tegra 3 officially released on November 9, 2011[/LEFT][/CENTER][/FONT]
Tegra 2's maximum ram limit was 1GB. Tegra 3's could be 2GB.

The rumor mill is churning out some specs on an upcoming Lenovo tablet with some funky specs, like 2GB DD3....so it's possible. However, the same leak/article also says its chip is clocked at 1.6 Ghz which is quite a bit out of spec, so I would take it with a usual:

You can read the White Papers on the Tegra 3 over on Nvidia's website. But the chip has a controller built into the chip that activates either the 4 cores, or the 1 core based on power demand of a given processing activity.
The quad vs single core are made out of different silicone materials, but same design structure in order to maximize the energy efficiency at the performance curve. The difference of Materials is more efficient at different power curves. So the 5th core is very efficient at low processing levels where it is actively being used.
It's pretty cool stuff

The rumor mill is churning out some specs on an upcoming Lenovo tablet with some funky specs, like 2GB DD3....so it's possible. However, the same leak/article also says its chip is clocked at 1.6 Ghz which is quite a bit out of spec, so I would take it with a usual:

*Correction: Tegra 3 supports DDR2 AND DDR3. The original Transformer had 1GB of DDR2 @ 667Mhz. The Prime has 1GB of LPDDR2 @ 1066Mhz, a considerable bump in speed. Also, Tegra 3 supports up to DDR3 @ 1500Mhz!

I'm sure it can, hopefully they increase the battery capacity to compensate for increased power use. As far as the memory, Nvidia's site on Tegra 3 lists DDR3 (though its still running on a 32-bit bus which may or may not be an issue with 3d games), upto 2GB. However, every bit of spec info on the Prime I can find lists DDR2...so I don't know.

The Prime's RAM speed is considerably faster than the TF101.
If it does have room to expand, could we expand or upgrade the RAM?

Judging by the pictures, it doesn't look like the RAM will be removable or upgradeable (the RAM is the Elpida chip right next to the processor).

I never said it wasn't.
What I said is that both Tegra 2 and now Tegra 3 have a single 32-bit wide memory interface when compared to the two on the A5,Exynos,Qualcom, and OMAP4 chips. What that means is that theoretically it will have lower bandwidth which may cause problems with upcoming games, especially considering that you now have to feed extra cores and a beefier GPU. Now, whether or not it will actually be an issue...we will have to see.
Sad that the SGX543MP2 in the Ipad2 is still faster than the Tegra3's GPU. Apple is always ahead of the curve.. Just when Android devices started becoming as fast as the iPad1.. The iPad2 was released and remains to have one of the strongest SOCs out in the field.
Even for pure CPU benches.. the 1ghz dualcore A5 smokes most chips running faster clocks in dual core configs.
Regardless, this is still the most powerful Android device to date. Just disappointed that Nvidia, one of the king of GPU makers can't even compete with PowerVR.. a much smaller company with a lot less money.

I would have to agree with you that Nvidia dropped the ball on their new GPU, at least on paper.
However, it's not as simple as having "omg wtf i > you" hardware that's the source of the performance. What Apple really has going for them is uniformity of hardware/software. Apple software is designed to work on very specific and strictly controlled hardware setup which allows for an incredible level of optimizations of software. This "closed loop" if software/hardware is what really drives the performance of the iProducts. Simply put, probably way over-simplified, but it let's them do more with less.

Very good point. Also apple has the apps n games that showcase and utilize all this extra power. Even my original iPad has apps/games that I haven't seen Android dual core equivalents of. I love my iPad but I also own Atix dual core Tegra 2 phone. I know the open sourced Android will win out in the end.
I came across a good comment in the lenovo specs link that a member here posted in this thread.
"Google and NVidia need to seriously subsidize 3rd party app development to show ANY value and utility over iPad. Apple won't rest on its laurels as their GPU performance on the A5 is already ahead with games and APPs to prove it".
What do you all think about this? Not trying to thread jack as I see it's relevant to this thread also. What apps/games does Android have up it's sleeve to take advantage of this new Tegra3? Majority of Android apps/games don't even take advantage of tegra2 and similar SOC yet. Are we going to have all this extra power for a while without it never really being used to it's potential. Android needs some hardcore apps n games. iPad has all the b.s. Stuff also BUT has very hardcore apps n games also to use it to close to full potential. IMO my iPad 1 jail broken still trumps most of these Tegra 2 tablets out now. Not because of hardware specs, but because of the quality of apps n games I have. I've noticed Android is finally starting to get more hardcore games like ShadowGun, game loft games, etc.. I can't over clock or customize my iPad as extensively as Android but the software/apps/games I have are great. No, I don't want an ipad2 or ipad3. I want an Android tablet now because of more potential with it. Just like with anything in life, potential doesn't mean sh$& if it's not utilized and made a reality.
I was a windows mobile person first. Then I experienced dual booting with XDAndroid on my tilt 2, I loved it. Then I knew I wanted a real android phone or tablet. First Android tablet I owned, for only a day, was the Archos7IT. It was cool but returned it since it couldn't connect to my WMwifirouter, which uses ad-hoc network. So I researched n finally settled on taking a chance with the apple iPad. I use to be an apple hater to the max..lol. My iPad changed all of that. I still hate the closed system of apple but I had to admit, the iPad worked great for what I needed and wanted to do. This iPad, I'm writing this post on now, still works flawlessly after almost 2 years and it's specs are nowhere compared to iPad 2 or all these new dual core tablets out. I'm doing amazing stuff with only 256mb of ram..SMH I hated having to hook iPad up to iTunes for everything like music n videos. So I jail broke and got Ifiles, which is basically a very detailed root file explorer. I also have the USB n SD card adapter. So now I could put my content on my iPad myself without needing to be chained to iTunes. iTunes only good for software updates. I'm still on 4.2.1 jail broken firmware on iPad. Never bothered or really wanted to upgrade to the new IOS 5.01 out now. With all my jailbreak mods/tweaks, I've been doing most new stuff people are now being able to do. All apple did was implement jailbreak tweaks into their OS, for the most part.
Sorry for the long rant. I'm just excited on getting new Prime tegra3 tablet. I just hope the apps/games start rolling out fast that really take advantage of this power. And I don't just mean tegrazone stuff..lol. Android developers going to have to really step their game up once these new quad cores come out. Really even now with dual cores also. I'm a fan of technology in general. Competition only makes things better. Android is starting to overtake apple in sales or similar categories. Only thing is Android hasn't gotten on par with apple quality apps yet. Like the iPad tablet only apps are very numerous. Lots are b.s. But tons are very great also. I'm just hoping Amdroid tablet only apps will be same quality at least or better. I'm not looking to get new quad core tablet to play angry birds or other kiddy type games. I'm into productivity, media apps, and hardcore games, like Rage HD, NOVA2, Modern Combat 3, Order n Chaos, InfinityBlade, ShadowGun, etc.. All of which I have and more on my almost 2 year old iPad 1.
Asus, with being the first manufacturer to come out with quad core tablet and super IPS + display, might just be the last push needed to get things really rolling for Android, as far as high quality software amd tablet optimized OS goes. Can't wait to see how this plays out .

That is correct. Actually, the "5th" core is licensed with ARM A7 instructions set, the quads are A9.

Again, I agree. Just like saying why Xbox360 and PS3 consoles can still push high quality graphics compared to a new high-end PC? Unity of hardware plays a big role there.
I have a $4000 custom PC. Sometimes I see my brother play the same games on his $250 Playstation 3 with performance and graphics very similar to my PC.

That's because these days, most PC games are console ports.
GPU specs don't matter. The iPad has more and better games than Android tabs, and that won't change for the (1-yr) lifespan of the Teg3. Not to be a downer, but it's just reality.
The Prime is better at certain things. HDMI-out and USB host (NTFS) support makes it a pretty good HTPC, for one. But I wouldn't get into a pissing contest over games--unless of course you're talking about emus.

Is that true? NTFS support? Are you sure? Can you link me to a spec for that? If so then I can transfer files from my SD to an external NTFS without using Windows! That would be great for trips when I need to dump digital pics.
I was trying to load Bejeweled blitz from facebooks desktop site and it looks choppy and unsmoothed. I tried it on my friends sg2 and its smooth as butter.
Making me wonder if the sg2 is much better than the prime? I have a g2x and its no where near the speed of the sg2 and I really thought the prime was able to load flash much better but not the case.
Nvidia always!
I cant reproduce it with flash games, but my experience so far is that the Galaxy S2 is MUCH smoother than the Prime in EVERY respect (with the exception of hardware video decoding, but hey...).
HOWEVER I definitely hope that is because of Honeycomb rather than Tegra 3. But I'll have to wait another 2 1/2 weeks for ICS to decide that...
The bizarre thing is that from pure specs, even the Tegra 2 is a faster/more powerful SoC than the Exynos in the SGS2, but it's lacking the NEOS which the SGS2 has. Also remember the SGS2 has to drive a much smaller screen. Also, flash can probably not use the quadcore (?) well.
So far I have to say in general smoothness Tegra 3/HC has been very underwhelming. And the 3 week delay of ICS in Germany does not bode well.
I am on ICS and its not that much of a difference in resolution for it to lag so much. All I can think of is tegra doesn't do well with flash.
Nvidia always!
Wow so I installed chainfire 3d on my g2x and installed the nvidia plug in and guess what? Seems as fast as the sg2. I take it flash just isn't optimized for nvidia. I am gonna try this on the prime and see what the results are
Nvidia always!
Alot smoother and just with chainfire. I wonder how or why?
Nvidia always!
A member of the Android team posted this about smoothness comparisons between the GS2 and the Galaxy Nexus. I think this may apply to the Prime as well.
"Some have raised points along the lines of Samsung Galaxy S2 phones already having a smoother UI and indicating that they are doing something different vs. the Galaxy Nexus. When comparing individual devices though you really need to look at all of the factors. For example, the S2's screen is 480x800 vs. the Galaxy Nexus at 720x1280. If the Nexus S could already do 60fps for simple UIs on its 480x800, the CPU in the S2's is even better off.
The real important difference between these two screens is just that the Galaxy Nexus has 2.4x as many pixels that need to be drawn as the S2. This means that to achieve the same efficiency at drawing the screen, you need a CPU that can run a single core at 2.4x the speed (and rendering a UI for a single app is essentially not parallelizable, so multiple cores isn't going to save you).
This is where hardware accelerated rendering really becomes important: as the number of pixels goes up, GPUs can generally scale much better to handle them, since they are more specialized at their task. In fact this was the primary incentive for implementing hardware accelerated drawing in Android -- at 720x1280 we are well beyond the point where current ARM CPUs can provide 60fps. (And this is a reason to be careful about making comparisons between the Galaxy Nexus and other devices like the S2 -- if you are running third party apps, there is a good chance today that the app is not enabling hardware acceleration, so your comparison is doing CPU rendering on the Galaxy Nexus which means you almost certainly aren't going to get 60fps out of it, because it needs to hit 2.4x as many pixels as the S2 does.)"
A link to the rest of the article is in my sig.
Yeah but why does it work as smooth when applying chainfire 3d? I mean its a world of difference there on both my devices.
Besides the prime has a quad core with a much powerful gpu than the s2
Nvidia always!
Try going to blitz on Facebook or g+ and play without chainfire and then with.
Nvidia always!
Got an s3 now and flash is awesome

So I've been lurking on the prime's forums for a while now and noticed the debate of whether the new qualcomm dual core will be better or the current tegra 3 that the prime has. Obviously if both were clocked the same then the tegra 3 would be better. Also I understand that the gpu of the tegra 3 is better. However, for normal user (surf web, play a movie, songs etc) isn't dual core at 1.5 ghz better in that an average user will rarely use more 2 cores? The way I understand it each core is able to handle 1 task so in order to activate the 3rd core you would have to have 3 things going on at the same time? Could someone please explain this to me?
First of all, the tegra 3 can go up to 1.6 ghz. Secondly, all 4 cores can be utilized by a multi threading app. Lastly, battery is great on tegra III due to teh companion core.

But the native clock for that qualcomm would be 1.5 meaning o/c can take it higher. Also doesn't being dual core compared to quad core give it an edge in battery? You do bring up a good point with the multi threading app. Also to clarify I am not standing up for the qualcomm chip or putting down the tegra 3 just trying to get things straight.
Thanks
Hey I'm the ....idiot aboard here....lol
But the tegra 3 has a companion core, being a fifth core, to take over when the tablet is not stressed. Thus saving the battery.
I am just repeating what I have read, I have no knowledge of how it all works. I guess that is how we can get better battery life.
Just trying to help the OP, maybe some one way smarter can chime in. Shouldn't be hard....lol
Quad core is better by far. On low level tasks, simple things, and screen off/deep sleep the companion core takes over. Meaning its running on a low powered single core. This companion core only has a Max of 500Mhz speed. So when in deep sleep or low level tasks, companion core alone is running everything at only 102mhz -500Mhz. Most of the time on the lower end. Therefore tegra3 has the better battery life since all it's low power level tasks are ran by a single low powered companion core. That's 1 low powered core compared to 2 high powered cores trying to save battery. Quad core better all around. We hsvent even begun real overclocking yet. The 1.6Ghz speed was already in the kernel. So if you rooted n using vipercontrol or ATP tweaks or virtuous rom, we can access those speeds at any time. Once we really start overclocking higher than 1.6Ghz we will have an even more superior advantage. Anyone knows 4 strong men are stronger than 2..lol. tegra3 and nvidia is the future. Tegra3 is just the chip that kicked down the door on an evolution of mobile chip SoC.

The maximum clock speed isn't all that important, since during tasks like web browsing, watching videos & movies and listening to music you will never push the processor to its highest available clock speed anyway. All mobile devices will underclock their processors so that you rarely have unused clock cycles eating up battery life. So all things being relatively equal performance would be about the same between both tablets during these types of lightweight tasks.
If you have a lot of background processes running, then the quad-core system might have an edge in performance since theoretically different tasks can be pushed off to different processors. However this use case is rarely found in Android. You might have an app checking weather or syncing photos in the background, or you might have music playing while you web surf, but those are generally fairly lightweight tasks that usually won't test the processor performance of your device.
In tasks that will stress you processor, such as 3D gaming, then quad cores have a very large advantage over dual core systems, despite the slight difference in maximum clock speeds. In addition the Tegra 3 has a more powerful GPU than the new Qualcomm chip, which will definitely make a noticeable difference in gaming performance.
Now when it comes to ultra-low power tasks or when the tablet is on Standby, the Tegra 3 uses its "companion core" which has incredibly low power requirements, so it can continue to sync your email, twitter and weather updates for days (or weeks) while having very little impact on the Transformer Prime's battery.
So in short, the Tegra 3 is more likely to outperform the Qualcomm in situations where you actually need extra performance. In light tasks performance between the two should be about the same. Battery life is yet to be definitively determined, however the Tegra's 3 ultra-low power companion core should give it an edge when only doing light tasks or on standb.
Keep in mind, the Tegra 3 in the TF Prime has a maximum clock speed of 1300Mhz. One core has a maximum clock speed of 1400Mhz. If all things were equal, a difference of 100-200 Mhz n a 1Ghz+ processor is practically unnoticeable in daily usage.

At least that is what Nvidia would like you to think.
The Tegra 3 uses an older ARM core for it's quad core design while Qualcomm uses their own ARM instruction set compatible core for their Krait S4 design. For most current benchmarks the Qualcomm Krait S4 dual core seems to outpace the Tegra 3 by quite a large margin. And of course Krait will be expanded to quad core later this year.

As unlikely as that seems considering the slower cores that Nvidia uses, links to real benchmarks ( not self serving white papers ) would be appreciated. I have glanced at your Tegra3 thread but have not read it all the way through after I saw that it seemed to depend a lot on a white paper and not real comparison tests. It is true that the current GPU the Krait uses is not as fast as the one in the Tegra 3, but graphics is only one element of overall performance. The only benchmarks that I have seen Tegra beat out Krait on were benchmarks that emphasized more than two threads, and then not by much.

I frankly think the power savings with the fifth core is mostly hype. According to many battery tests I've read online and my own experiences with my Prime, it doesn't get much different battery life from dual core tablets.
Quad core is better for future but problem for backwards compatibility... it's definitely good for tablet.

No dual core android tablet battery last longer than an ipad1. My prime easily outlasts my Ipad in battery life. The battery hype is real. Tons of people here seeing 9-11hrs+ on a single charge with moderate to semi heavy use on balanced mode. Even longer on power savings mode.

I think if Krait were to come out with quad core then it would beat out tegra 3 otherwise no. Also they are supposed to improve the chip with updated gpu to 3.xx in future releases. Also benchmarks have been proven to be wrong in the past so who knows? Not like benchmarks can determine real life performance, nor does the average user need that much power.
Companion core really does work

Strange, we just started uni here (Australia) and I've been using my prime all day, showing it off to friends (to their absolute amazement!) showing off glowball, camera effects with eyes, mouth etc. 2 hours of lecture typing, gaming on the train, watched a few videos and an episode of community played music on speaker for about 40 mins, webbrowsed etc etc started using at lightly at 9 am (only properly at say 1:30 pm) and it's 10:00pm now and GET THIS!!:
72% battery on tablet and 41% on the dock. It's just crazy man. No joke, it just keeps going, I can't help but admit the power saving must be real :/

That's what I'm saying. Battery life on prime is great. Add a dock n battery life is sick!
I do agree a quad core variant of krait or S4 will give tegra3 a really good battle. Regardless I'm more than satisfied with power of tegra3. I'm not the type as soon as i see a newer or higher spec tab, ill feel like mines is useless or outdated. With have developement going hard now for this device. Just wait till the 1.8-2ghz+ overclock roms n kernels drop. Then we would even give new quad core higher speed chips a good run.
Above all of that, Android needs to developement more apps to take advantage of the more powerful chips like tegra3 and those that's upcoming. Software is still trying to catch up to hardware spec. Android apps haven't even all been made yet to take advantage of tegra2 power..yet lol. With nvidia/tegra3 we have advantage because developers are encouraged to make apps n games to take advantage of tegra3 power.
Regardless we all Android. Need to focus more on the bigger enemy, apple n IOS
I have read many specs showing the Denver having a massive CPU performance.
However, all of these are "Single Core" performances @3Ghz.
Multi core performance, is just, on par with quad core benchmarks.
However, when I am multitasking, is this going to be a serious issue, with all the overhead of context switching and stuff, especially since Nexus 9 is clocking this at 2.3Ghz (a massive 25% reduction from benchmarks)? I mean, quad core is quad core. Single CPU performance can only do so much.
From the looks of things it'll pull it's weight for multi core loads as well. The only thing that out performs it on multi core workloads is the Galaxy Note 4, and even then it's not by much.

Thanks. This should be enough to do pretty much anything seamlessly. I am primarily interested in graphics performance, one reason being the QHD screen, and that is mind blowing anyway.
Don't know why they removed 4K recording, as the CPU and GPU can handle it.
There might be a mod for it in the very near future? 4k

QXGA (2048 x 1536), not QHD (2560x1440). Close enough though, only about a half million pixels difference between the two.
Multicore performance doesn't matter much in real world scenarios.

Thanks. You are indeed correct. I was just looking at Nexus 6 and note 4 and "missed" it. Besides, that half a million pixel difference (actually 540672), is only 17.19%, so The Tegra K1 won't notice it anyway
And now I'm unsure. Why would they put a lower resolution in N9, when they are putting QHD in N6?

same with ram.
Maybe the price would be to high, like it already is?

It is really impressive to see a dual core getting the same performance as a quad core in multi-threading tasks, shows just how powerful the cores are. I dont think it is a setback really since it isnt performing a lot worse, and single thread gets such a large boost. This is Nvidia's first every CPU core, and it is really impressive. I am sure we will see a quad core version next generation or so when they can make the processor on a smaller node.
Being that Android L doesn't appear to have multi-window or floating-window multi-tasking, I don't think the lack of a quad-core is a big issue. Many Macbook Airs and Surface Pros have been running dual-core forever (even current models), and you could argue that people do far more multi-tasking on those full desktop OS's than an Android tablet.
Also, related, Antutu benchmark of the N9 from the other thread - http://i.imgur.com/c6b57dT.jpg

More likely, they are trying to match it with Apple's iPad Air 2, which seems reasonable.
However, they probably should have gone with 1080p in N6. That is wayyy overpriced.
I would have preferred to get a QHD in N9 and QXGA in N6, which would have given N9 an edge.

I am actually waiting for an A8X vs N9 (Denver) benchmark as I read stuff like "they turn off graphics features on Android despite more powerful hardware".
If the above holds true though, I'll probably get N9.
