I heard that Nexus 9 will be the 1st 64-bit tablet. What does that mean considering that it's a mobile device?
Is it just marketing or will it actually make some difference in the performance?

Nvidia Doesn't disapoint us, so we might actually see an upgrade in performance , but there are many apps which doesn't support art which is very sad .
It represents quite a substantial jump in performance, particularly on any thing that favors single threaded performance. But don't just take my word for it.

It's just marketing. Yes the 64-bit version of the Tegra K1 is more powerful, but it being 64 bit doesn't add much outside of that.
Edit: Let me put it this way: If Google had gone with a different 64 bit chip, like for example that 64 bit Snapdragon 400, it wouldn't have given any performance gains over 32 bit. It just happens that Nvidia makes two versions of the Tegra K1 and the more powerful version happens to be 64 bit.

The reason they don't support ART is because they use libraries that don't support ART. However, if Google is releasing ART with no other alternative, I would guess that most of the Google libraries, if not all, will support the new runtime. An app that I know doesn't support it is Xposed Module, which is a shame.
P.S. I do have Nexus 5 running in ART and I have seen only two apps that didn't work with it. One of them was updated and now works.

One more reason to pick up a Nexus 7.

Nope. The iPad Air was the first 64-bit tablet. N9 will be the first 64-bit Android tablet.
But don't let any of that fool you. Right now, 64-bit SoC mean nothing, as there are no 64-bit apps and no tablet has more than 4GB of RAM, which is the main reason to use a 64-bit architecture.
Of course, that's going to change in the near future. Android L, being itself 64-bit, will spur the development of 64-bit apps, and tablets with more than 4GB of RAM will inevitably get made.
Buying a N9 right now exclusively because it's 64-bit will be a waste of money.
At the end of the day it's the fastest SOC out there, 64bit or not. Let's just look forward to it.

Android L can also run in 32-bit mode which all phones will be doing until we start seeing 64-bit chipset releases there too. Do we know for sure that the Nexus 9 is even running the full 64-bit Android L release? Or is that planned for the future when Google gets it finished up or something?

So... Windows 8 is verified to run on arm, and a friend of mine was saying that the tablets they used in the BUILD demo were tegra 2.
Anyone seen any releases for ARM anywhere? The sooner I can start using windows 8, the better.
The presenters are incredibly dorky, and i think I might have gagged a little every time they said "bold," but wow - Windows 8 is pretty powerful stuff. It's not going to kill Android and iOS, but it's gonna drag them into a dark alley and kick them in the kidneys a few times.
AFAIK Nvidia is going to support Windows with the quad core Tegra chips. I.e. if you want the new OS, buy a new tablet. Just like Nvidia supports new versions of Android with the latest (1 GB ram) Tegra 2 chips.
Edit: here's a link for ya: http://www.engadget.com/2011/09/13/nvidia-opens-windows-8-developer-program-with-support-for-kal-el/
Well, be on the lookout for ARM previews - they've got some (alpha) x86 and x64 demos out for developers, so it shouldn't be too long before we see an ARM release. The whole thing has me pretty stoked.
http://www.engadget.com/2012/06/04/asus-tablet-600/
Same Tegra 3 but 2GB ram.
Hope DEV can ported Windows 8 to our Prime or official ported from Asus
Look at it! I saw Battlefield 3 in home screen!!!
1366 x 768?! It really sucks.
Hope Win8 will be ported to Prime. I don't like Win8 interface but it could be useful sometimes.

The bootloader capable of booting Windows 8 will not be able to boot something else not signed with the right Microsoft key.
Windows 8 for ARM will not boot without the correctly signed boot loader.
There is a very small possibility that they will find some exploit in the Windows 8 ARM version boot process, but chances are great that Windows 8(RT) will never run on the Prime or other current Android tablets.
Seeing as how windows 8 is not open source and that it is infact a licensed/paid product I highly doubt we will see a port of it to anything with out some level of legal ramification. That said its even more unlikely that a port would be allowed on XDA because it could very easily be considered be the use of wares to install a cracked version of windows 8 (especially when you consider that of the android centric sites out there XDA is pretty visible to the public eye)

You just linked to a hybrid ultrabook.
As for tablets... 600 and 810... both are running 1366 x 768 resolution.
600 = Tegra 3 (that means you can't play Skyrim natively as ARM doesn't run x86/x64 legacy software).
810 = Intel Atom(medfield SoC) (you can run Skyrin as it is based on x86... will it actually run well is the question as the GPU inside Intel Atom is garbage).
Btw, Acer Tablets actually look better with higher resolution.

Not sure where you got Discret Nvidia Keplar 28nm GPU from. Nvidia GPU... yes, but Keplar GPU? where did you get that info..... i really doubt it is Keplar GPU (with all the issues they have currently.....)
My 2 cents
I like windows, and would love to have a tablet with Win 8 on it. Much more compatible with my desktop running windows.
But with android, you get open source, Custom ROMS, and games and apps are a hell of a lot cheaper.
Ill stick with Android..

http://hothardware.com/Reviews/NVIDIA-GeForce-GT-640M-Kepler-Goes-Mobile-with-Acer/
they are the latest Nvidia Discrete GPU line.
Half are based on Fermi, and the other half (after 640M) is based on Keplar.
I haven't seen anything being mentioned as 28nm... but just as Nvidia Discrete GPU. Based on rest of the specification & intended target audience.... I doubt it'll be Keplar based GPU. Plus, Nvidia is having issues with Keplar based GPU atm... could all change by the time this device is actually released....
but my guess is Fermi based Discrete GPU.
Edit: http://www.engadget.com/2012/06/04/asus-taichi-notebook-tablet/
Only interesting product from Asus for me. I like the concept... but it is definitely for a very small niche market. While everything sounds practical (at least for my use)... I have to wonder how practical it will actually be once you factor in the battery life, overall weight of the hybrid ultrabook, and etc...... Not really a fan of basically all of their "device" looking the same either.
First thing I noticed was the large plastic RF window, much larger than Infinity's.
The 810 has 64GB, 600 has 32GB. Like Prime, neither has USB on tablet. I can't imagine a Win device w/o USB, so am wondering if the dock comes standard, or at least with a bundled SKU.
Disappointing that the 810 is 1-core Medfield and not 2-core Clover Trail. Ditto for the 600, with moldy Teg3.
810's 11.6" size is off-putting for tablet (one-hand) use. Envisioned use: mainly docked with occasional tablet use. As a tablet, the 600 is more attractive, and should cost less.
Both models are 1368x768, which yet again is disappointing for the larger 810. The Acer W700 is same 11.6" but with fullHD (1920x1080). BTW, interesting that Android tablet gets the 1080p screen and not Win8.
No real surprises on the HW. The big question is price. Given the wimpy SoCs, these shouldn't cost too much. My SWAG: 600 = $500, 810 = $600. Plus $150 dock.
Anybody get the point of Asus' Taichi double-sided-screen notebook? My reaction: WTF. Looks like for people who need to do demos to clients. Niche, like the PadFone. Probably concept-ware.

yes there's a discussion going on about it
I've noticed a trend that all these tablets/slates that I've seen so far have 2gb of RAM; do you guys think it would even be possible for it to run on 1gb? I suppose the question would be hard to answer this early on?

I run the x86 beta in Virtualbox with only 1GB of RAM and it idles at about 400MB of usage. The Touchpad is hardware capable of running Windows RT, but the issue will be drivers and the fact that Windows RT is not going to be sold so it may be pretty hard to port it over and get it booting. There are also piracy issues as Windows RT is not free but also cannot be bought.

I think this point is really what's going to break compatibility for "CAN I RUN WINDOWS RT ON DEVICE X!?" - with android we have access to the original sources and with most devices a fair amount of access to enough of the device drivers to get android version X running successfully on random arm or x86 device y. this lack of access is what's going to severely limit availability of windows rt devices on devices that didn't ship with windows rt.
That having been said, there may still be a ray of hope for running android as a secondary OS on devices that DO ship with Windows RT - like jailbreaking an iOS device, it should be a perhaps not entirely simple process (and only on extremely popular or susceptible devices) to break the crypto and protocols on the bootloader, map the partition scheme, and get a linux kernel booted on it and thus, partition or create a disk file containing the android OS such as the open iboot project on iphone http://www.idroidproject.org/wiki/OpeniBoot
Hey everyone,
My name is Michael Heller. I'm a writer with PhoneArena.com and I'm working on an article about what Google has to do in order to move Android into the 64-bit world. The article is a work in progress, but I was hoping to get some insight from those of you who likely have more knowledge and understanding of the code than I do.
The article (still in the process of being written), can be found here.
As you can see, I have the basic framework sorted out, but there are some specifics that I need help with relating to the Dalvik VM and the Android runtime and how it will all work once Android is updated to 64-bit, but is still running 32-bit apps. From what I've learned so far, is that Android's multitasking will gonna cause issues on ARM64 due to its *mandatory* EL handling when switching between 32 and 64-bit mode. A single 32-bit app running on 64-bit Android will cause performance issues for the system, and drain the battery much faster.
I'm wondering if there is a way to avoid these issues with bytecode apps on a 64-bit machine, and I'm hoping some of you can help me out with basic fact-checking in my article.
Thanks!
Well, if Google wanted to start building a 64 bit version of Android, I guess wouldn't be hard, seen as we already have 64bit linux distros for a while.
The only thing I can think of, is either a 64bit implementation is not required yet (available software for android still manages fine with 32bit limitations), and/or Google is keeping the face with the hardware manufacturers.
Eventually will happen, it's just a matter of needing. (Typical market demand).
From my point of view 64 bit will be manitory as 4GB devices will be needed with the super screen resolutions coming soon. I have a Nexus 10 with 2GB but due to the memory allotted to the screen there is not much left for apps. This last week Samsung announced even screen higher resolutions coming next year.
Good insights but he's looking for technical descriptions

I still don't get why people think the memory has anything to do with 64 v 32. I have never heard a person ever say "oh you machine is laggy because you have a 64bit machine and not enough memory." until I found this sub-forum. The iPhone/iPad have had 1-2GB of RAM and not had any huge performance issues while being 64bit.
There are memory issues, that's it, nothing to do with it being 64-bit or not. 3GB MAY "fix" the issue, but that would really just mean the machine would go longer until it started to show symptoms. The nexus 5 and 6 had LOTS of memory issues on Android 5 and no one ever said "it's not enough memory" and not being 64bit hardware they couldn't blame that, because it worked fine on 4.X. We have no 4.X to compare with, so everyone just wants to blame 64 bit when really, it just needs more software fixes that Google isn't spending time on.
If anything having a 64bit CPU just means the CPU can work harder and faster, even if it was running 32bit software. I know that not many developers ahve latched on to the n9, but i would NOT be surprised if a few clever ones could figure out what is actually causing the memory leaks/aggressive paging. For example on my n6 it is using about 4-500MB less ram, just to to Android OS and Google App. There is nothign about being 64-bit that means the Kernel needs over 2x's the memory usage. Something is making it keep memory instead of releasing it. I am not smart enough to know what that "something" is, but I'm sure someone that develops and has an N9 is smart enough and can file a bug report for it that we can all upvote.
If there are any current open bug reports for memory usage on the n9 please link them to me, I will gladly upvote them. Lets just be clear there is no reason to suspect this is anything more than a software issue.
To Update:
Here is a bug report i found of the problem, if more people could Star it then it can get up the priority list.
https://code.google.com/p/android/issues/detail?id=175232
People like to blame the 64bit OS because the switch does make processes consume slightly more memory. If implemented poorly, a 64bit OS can eat up a lot more RAM. Windows XP 64, any Itanium based system and many early x64 Linux distributions come to mind.
Somehow Android OS on my N6 averages 220mb, while it's 800+ on the N9. Because the N9 is 64 bit, that change seems to be the obvious culprit. Clearly, the N9 didn't ship with enough RAM based on the OS memory use as somehow the N6 has 3gb for an 220MB OS footprint and the N9 has only 2mb, despite an OS that eats almost 4x the memory.
Switching to a 64bit OS should make the CPU, RAM, etc. all run 'faster', but if there's not enough RAM to hold running software, the experience will slow down as more processes need to be shuffled in and out of RAM. Look at what happens to a computer when it 'runs out of RAM'. The constant game of musical RAM chairs will more than erase any gains from switching to 64 bit.
In my mind, there is no question that SERIOUS problems exist with this device. The fact that this is one of the first 64bit Android devices is almost definitely a contributing factor, but the slightly reduced efficiency of how 64bit memory is allocated can in no way explain the problems with the devices. Something MUCH deeper is going on. Based on some research, here is what I've learned.
1: Some part of the OS is using an obscene amount of memory. Some of this is probably Google's fault because 64 bit Android just wasn't ready. I'm also pretty sure nVidia and HTC are more to blame for this issue than Google.
2: There's still not enough RAM. If the N6 has 3GB, there is no reason why the N9 shouldn't. Most tablet users run more memory-intensive
3: HTC built a bad device. I've had cellular issues with VZW & ATT which have been discussed in these forums and are obviously HTC's fault. I've also read about there being some hardware issues causing the ram to 'freeze' which required a replacement device.
4: nVidia's hardware sucks. More accurately, their x64 bit implementation of the hardware.
5: Graphics: I BELIEVE THIS IS THE GIANT ELEPHANT IN THE ROOM OF ISSUES. The nVidia Shield has similar hardware with a standard HD screen. The N9 has a different aspect ratio and a lot more pixels. The horrible application switching lag even with relatively low memory use (a process that is still taxing on the GPU) makes me think this is the main flaw of the device. This problem could also make the OS eat more memory to make up for the OS issues. A graphics issue would be everyone's fault. Google is to blame for insisting on this change when the other hardware just couldn't support it properly and choosing partners incapable of delivering the hardware to properly support the screen. nVidia and HTC to blame for not providing sufficient hardware and software support for the screen.
In reality, I think several factors combined to produce this issue. The components of the system were designed primarily for 32-bit implementations of Android. 64-bit support was baked into them, but it wasn't the focus of the components. The device itself was probably designed before 64-bit Android was even available to test properly. Because the pieces looked like they should fit together on paper, everyone just assumed they would. Unfortunately,for some components the fact that they could run in 64-bit mode, didn't mean they would run well.
x64 gets blamed because it is unknown. The average user has no idea what it means to have a 64 bit platform vs 32 bit. IMO x64 is unneeded unless you're mapping 4gb or more RAM and doing a lot of computations with large numbers.
There is most certainly a memory penalty since the os must run 64 bit code and likely have a vm of some sort to run all the existing 32 bit stuff. In windows this is obvious as you have program files and program files (x86) folders as well as windows\system32 and windows\syswow64 humorously the former is the 64 bit subsystem and the latter is the x86 subsystem. This is why you should plan ahead when architecting your applications and not name your folders poorly.
All that said, I have an htc m9 in addition to the nexus. The m9 is also 64 bit and has no issues. Not an apples to apples comparison since it is a Qualcomm processor with 3gb of ram and less pixels but it should indicate that 64 bit android is not the problem in and of itself.
Thanks guys. 64-bit apps should use at most 15-20% more RAM compared to their 32-bt counterparts, simply due to the fast that 64-bit assets are larger. The issue we have is that in cases like Android OS, using over 120% more memory than on a 32bit device. It also for some reason seems at times to feel like the GPU is taxed and it definitely should not be. So either the GPU drivers are buggy or the GPU memory is very limited. Luckily much of this is improved on 6.0, but there are still issues that need to be addressed in the OS itself.
Because saying "I do not know why my Nexus 9 performs poorly" is boring. Jumping to conclusions is much more exciting and dramatic.

I suspect you are right that there are driver issues. Sadly our only recourse is to wait on nvidia/htc/google to rectify the issue.
Don't know what it is but 6.0 is not what I expected. Jerky , slow loading and very unpleasant to use. Have never rooted or rommed. Don't think I should have to. Did a FDR, no improvement. Have to constantly clear app cache and system cache to make it tolerable. Hoping for some relief from Google
Android 6 on my stock nexus 9 has brought every task switch of any kind to a near unusable lag. 4 to a full 20 seconds is the norm now. In fact, just about every response to user action in every app has this problem now. I've got almost nothing except Google's apps, many of which I don't use, but still have something running.
The tablet is now a paper weight, almost. The delays make it unusable, as you can't tell whether an interface action didn't "take", or is just laggy.
I did this as an update. Should I just wipe and reinstall clean? If so, where do I get the necessary files and instructions?
Thanks for any insight.

I wish I would have returned it, but haven't because I thought they were fixing the memory leak. And after fixed it turned out that all other Nexus devices do well but not the n9.
Feel free to try my ROM if you're unsatisfied with what Google has done with stock.

Does it have lower system ram usage? There are people (like me) who want just use their device as a normal user and get ota updates and not flash the device manually every few weeks. It's very nice that you are sharing it anyway!
Everyone try first "safe mode" on Nexus 9 for 3-5 days to see if this app or hardware problem!
Press and hold power button
pres and hold "power off" option
then choose OK.
If problems gone (lag, resetting) then do factory reset without backup, install app manually not all at once from backup. It helped mine Nexus 9

I think you'll be happy. Popular quote that people often use is:
You have breathed new life into my Nexus 9.

With that said, it's entirely possible to flash one build and stick with it for however long as you wish. When you do decide to update, you simply create a backup, "wipe", and flash the newer build with some gapps. Something to keep in mind here is that Nexus devices were created to be fiddled with. If you aren't fiddling, you aren't getting the full experience. It is a developer's device, after all. :highfive:
If this is a road you do decide to travel down, just be sure to do a lot of reading and understand what you're doing prior to doing it.

It's a normal end user device, too. And for me the only choice. Don't like apple products at all. Don't want to buy a device and then not get updates. To be exactly, I want to know before I buy and not hope that Samsung, lg or whatever are so friendly to update. And, I don't like the modifications they do to the UI. So for me there is no other than Nexus. But I don't want this special fiddling experience. (For now. I will probably install a ROM on my Nexus 7 2012 some day)
According to this document
https://01.org/android-ia/user-guides/android-memory-tuning-android-5.0-and-5.1
64 bit indeed increases ram usage a lot...
I also have the impression that this is rather an issue with the Nvidia chipset or the general hardware design than with the system being 64bit.
This morning I had a very LOL moment when I read the Google Pixel C review of The Verve:
>>The specs are also huge: 3GB of RAM paired to the latest Nvidia X1 64-bit processor. That all seems good, but something is amiss with performance on the Pixel C. There are inexcusable pauses and latency, especially when launching and switching apps. <<

So the problem still seems to be out of control. Too bad.
There are many threads about the Nexus 9 and memory issues but I have yet to see any reports of specific analysis of the issue on a problem device. I've had no memory issues with the Nexus 9, 7, 7(2013),5 and Asus tablets. I seen no evidence that there are hardware differences between Nexus 9's (except the pre release version tested for FCC emissions had a Miracast chip) and I believe it is down to the apps that users run. In support of this opinion:
Resets are recommended to clear the issues.
Google state at Investigating Your RAM Usage Although Dalvik and ART perform routine garbage collection (GC), this doesn’t mean you can ignore when and where your app allocates and releases memory. In order to provide a stable user experience that allows the system to quickly switch between apps, it is important that your app does not needlessly consume memory when the user is not interacting with it. Has anyone with memory issues looked at the recommended tests at the link above?
The quality of apps published. Anecdotal evidence (I hope it's wrong) that publishing an app on Google store can be done in 30 minutes but Apple requires "days". I've never owned an Apple product I'm just saying that to me, not a software developer, that the compliance standards imposed on the software tested may allow bad coding to slip through.
