    It would be rather nice if they just happened to upgrade the processor to be Tegra 4 based... This platform, with Cortex-A15s, could make a rather nice general purpose computer for those of us who use Linux. Reply

    NVIDIA has a video driver for discrete Kepler GPUs built for the ARM ISA? Interesting. :)

    Too bad they aren't going for DIY desktop, fileserver and HTPC markets ,i keep waiting for the ARM guys to establish some standards and go for this market. We need some fun.
    Nvidia said a while ago that they'll use Denver in Tesla on the server side so maybe Kayla is not all about Logan.
    It is odd that nobody mentions that Denver is late if it comes in 2015 ,granted Nvidia wasn't listing what core they are using in Logan so could we see Denver in it? Most likely they messed up and Denver is late but who knows...

    Have you confirmed that they are using Cortex A57 in Tegra 5, or are they still going to use Cortex A15 in 2014? Reply

    If Parker is their "first 64 bit chip" and Logan isn't, then Tegra 5 will be based on Cortex A15, unfortunately. I just hope they at least make it at 20nm. But it still shot down my chances of getting a 64 bit device in 2014. Reply

    "Because Kayla and Logan are Kepler based, the GPU will be well ahead of OpenGL ES 3.0 with regards to functionality. Tessellation, compute shaders, and geometry shaders are present in OpenGL 4.3, among other things, reflecting the fact that OpenGL ES is a far more limited API than full OpenGL. This means that NVIDIA is shooting right past OpenGL ES 3.0, going from OpenGL ES 2.0 with Tegra 4 to OpenGL 4.3 with Logan/Kayla. This may also mean NVIDIA intends to use OpenGL 4.3 as a competitive advantage with Logan, attracting developers and users looking for a more feature-filled SoC than what current OpenGL ES 3.0 SoCs are slated to provide.

    I love how with Tegra 4 nVidia went around promoting how being OES2.0 based is so much more die area and power efficient compared to OES3.0 mobile GPUs. And now a year later with Logan they will jump to the opposite end of the spectrum and bring over a full desktop API which no doubt includes features that are unnecessary or inefficient for mobile and play it off as a great design decision.

    In 2015 we will actually use it. Well, maybe...LOL - I'm saying devices show up late 2014 and games using those features AFTER that, not talking chip debut here. In 2013 it's a waste of die space and power. Do you see anyone using DX11.1 this year on a mobile product? NOPE. Yet, Rogue6, Mali, Adreno etc are all bragging about this ES3.0 & compute...You don't see them producing benchmarks, just "we've got this feature, and that feature...blah blah". We're just now getting unreal 3 type games and they won't be pushing the details you get in that engine on the desktop. NV chose wisely allowing them to hit better power targets/cheaper die size and jack up perf on what we will actually USE during T4's life. I think everyone else missed the whole point this gen. As we start to get REAL game benchmarks this year we'll see the point of nvidia's move. Dx11.1 & ES3.0 won't speed up your unreal 3 game nor make it look better on mobiles (without hitting single digits anyway). To turn all that crap on will take us back into a Nexus 10 situation or worse where it's not quite fast enough to push their res.

    I think T4 barely cuts the mustard at 2560x1600 and exynos5 is woefully underpowered for 2560x1600 in nexus10 (for gaming). T4i with 12 less cores should be about the same on 1080p (as T4 at 2560x1600 roughly) where top phones will be for the next year...There's really no point in going higher res in either case right? I won't see the difference anyway. I think we'll just keep seeing them jack up perf at these two resolutions (tab/phone respectively) or enabling more graphic features going forward. But for this year and most of next year you should have designed for cut down unreal3 engine type graphics (think dx9.3 type). GPU compute is pointless on mobile too for quite a while. I don't see anyone doing WORK that requires that on a phone or tablet (like I'm going to dev content on a tablet or phone...yeah right), and games barely use it on a PC. So any space dedicated to this is wasted until you can show some legitimate USE for it. I can't really name much on a home desktop that compute is for (civ 5 benchmark to prove it works? - Bitcoining? Folding at home?...LOL@all of these). I'm not saying it won't be important at home one day, just that it's pretty pointless right now (which is why NV majored on gaming for kepler and NOT compute).
    I'm guessing most of these (and more) will be on android soon. Some already are but devs aimed at ios first as it looked like apple would rule forever, but android has ended that cycle this last year. More devs will head for android going forward I think as android is dominating now and pre-orders of galaxy s4 are 4x S3's at some places...WOW.

    Can anyone name a released game on mobile using ES3.0 or DX11.1? If so I guess I missed it :) I predict I'll be asking the same question with no answer for over a year :) Heck any in development even? The biggest thing for me here is all gpus from here forward in mobile should be ~xbo360/ps3 and be able to get a lot of crap ported from previous dx9 stuff on these. Everyone is jumping on the phone/tablet or ouya type stuff with gamepad as a console. Samsung just demoed a gamepad with S4 out to tv in the last week, Shield, ouya, moga, greenthrottle etc. X720/Ps4 might be irrelevant before they even ship this time. They'll be lucky to sell 20mil units for Q4/Q1'14 total for all 3 consoles, vs. ~25+x that for phones/tablets in those two quarters and most will be xbox360/ps3 quality power. How do you survive that onslaught? EA/Sony/Nintendo/Activision/MS will be pretty much the only people producing stuff IMHO as no small devs can afford the failure possibility of the devices themselves. Right behind their launch we'll be hearing about T5/T678/Rogue7/A340 (whatever they call all these). Sales of consoles will continue to face more an more power in your hands that can get to a TV. This gen was doomed on the vine; they just didn't realize how powerful your phone or tablet etc would be when they started their work on them.

    One more comment: I noticed stark is missing and no mention of boulder. Are these the same, or just further out or something? Boulder was supposed to be 2015, denver 2014. But now that denver is being discussed by some as potentially used in server is boulder just not on the map now? Stark on a whole other roadmap these days that's purely server/hpc related? This was pretty much the desktop/mobile talk so maybe this explains the absence?

    One more thing, just got a warning for dailytech being a dangerous site...LOL.

    I personally would use a Parker-based laptop (with a KDE-based distribution), particularly with a 1600x900 13"/14" screen at $200-250 (would want mSata SSD accessible Reply

    As such I'd want gpu computer and such, hence my rant. Reply

    $250 Chromebooks with Parker in 2015 are definitely going to be awesome. Reply

    It reminds me CARMA DevKit from Seco. What`s the difference?
  • Ryan Smith - Wednesday, March 20, 2013 - link

    SECO's Kayla kit (they're one of the confirmed vendors) will be a refit of that kit. The Quadro 1000M GPU will be replaced with the new Kepler GPU. Reply

    does using opengl 4.3 mean that android apps can use opengl 4.3 instead of the crappy es 3.0? Reply

    Post reading comprehension fail on your part. :)

    Note the "happened to upgrade the processor", meaning, in the future.

    A future release with A15-class CPUs and dGPU-class iGPU in that form factor would be a nice general-purpose box, or even HTPC.

    i belive the Kayla is just the nvidia's Old ARMA
