    A demo of Kal-El at least shows they have it up and running. If they can get a bit better battery life with that seemingly smooth playback of 1080p utilizing around ~50% of 4 cores. Hopefully we'll see some new tablets before the end of the year! Reply

    50% of four cores to play 1080p video is a big problem, because they shouldn't be doing video decoding on the CPU. Offloading video is extremely important on an SoC platform. Reply

    I just hope it is a sign of immature drivers :)

    Ideally the usage on all the 4 threads should be close to 0 (The 'VPU' engine should do the full decode acceleration)

    You forgot the most important part.

    ARM prides its self in low power consumption. ARM A9 ( or is it really A15 . . .4 cores . ..) has very light power consumption. I do not know about this particular processor/setup, but it would not be too much of a stretch to think this setup is using 2-4 WATTs. Before LCD screen usage.

    There have been demos of ARM A9 dual core beta products using 2W while doing the same task. Though in Chrome OS. 2W while playing back video. Without dropping frames.

    After that. Considering that a Tegra 3 system can be comparable to a Core 2 LUV system in performance . . . Well, lets just say "Atom who?".

    You forgot the most important part.

    DSP normally does most of of the video decoding on ARM. If DSP was utilized CPU usage and power consumption should have been lower.

    If iPad CPU used 2 Watt during video decoding it would not have been able to provide 10 hours of video playback. It's got 25 watt-hour battery and display consumes most of it.
    CPU+DSP+everything else have to consume less than 1 Watt for good battery life.

    "CPU+DSP+everything else have to consume less than 1 Watt."
    Except display, of course, I should clarify. Display will consume 1-1.5 Watt.
    It's hard to do that without DSP and it's hard to fit more than 25 watt-hour battery in slim tablet. So they better have DSP drivers working.

    Key word; notebook. Not a tablet. I doubt very seriously the iPad will compete performance wise with an e7300 CPU performance wise. Reply

    Also, let us not forget, this is still early stage. Microsoft probably has not optimized is software for ARM just yet. Drivers probably could use some work too.

    Still even though I think low power is great, there comes a point when too low, is . . .well too low, and performance then should be given more consideration.

    Windows on ARM is interesting, but Microsoft has been skating around any sort of question about compatibility. Obviously anything .NET is going to work fine, but what about everything else? They've been hinting (but I don't think outright confirmed without later hedging) that they'll not have any sort of emulation for x86 core. What, then, about fat/universal style binaries? What will they be doing to ensure that there's actually software to run on these things? Reply

    Could you give an example if something not .net that is really important for Win8 to succeed on ARM?
    There must be plenty of ARM based software out there already, and I would hope the quality will get better now that MS has signed on.
    I guess I'm still a little confused about the supposed cross-platform compatability of Win8. Will we really have to get different programs for an ARM vs an X86 variant?
    I can see that becoming a real bummer, especially if you happen to own an ARM tablet and an X86 desktop.

    Yeah, they need to solve that one.

    I can see App Store purchases having both versions with one purchase, but legacy apps are a non-starter on ARM. Although I have trouble coming up with anything I'd want to use on a tablet that I use on my desktop.

    Still, including a basic x86 emulator on the ARM tablets wouldn't be out of the question.
  • softdrinkviking - Thursday, June 02, 2011 - link

    I think that intel wouldn't allow it. At least not until ARM is in a position to cross-license. (from intel's point of view) Reply

    Emulator is software, so shouldn't be an issue. Microsoft however have shown no sign of implemention such a solution. Reply

    Anandtech needs a "Report Spam" button next to "Reply". And also a "Delete" and/or "Edit" button on posts you have made.
  • ganeshts - Friday, June 03, 2011 - link

    Took care of that ...

    Will talk to Anand later about how to deal with this.

    Please, microsoft, use the fact that all windows apps will be recompiled from source to cut out all the legacy dross from the windows API and make it a clean and slim system.

    Since you don't need to maintain binary compatibility you have a rare chance to clean things up! Don't succumb to the pressure to make windows on arm the bloated bag it is on x86!!

    this is going to be amazing in a netbook if they can keep the prices down. are we finally going to see usable $200 netbooks? that remains to be seen but im hoping.

    in the future if nvidias roadmaps are to be believed tegra is going to be potent even in the desktop area, at least relative to gpu performance. the successor to the a15 is supposed to add multithreading of some sort as well, its going to be a real beast.

    i mean with the pull that nvidia has with game devs, it isnt so hard to believe that were going to get games ported to arm as well, and id be suprised if valve doesnt port their source games over.

    all nvidia has to do is get some version of tegra into a next gen console and theyve got it made.

    its all really exciting!

    Anandtech still doesn't have a way to identify and remove spams nor allows it's read to identify spam messages.

    It's 2011 already.
