GPU Performance

On the GPU side of things the iPad Air 2 seems to have a GX6650, which should provide a healthy boost to GPU performance when compared to the GX6450 in the A8. Apple has placed a strong emphasis on gaming for their iPad line, so there are some obvious comparisons to be made between NVIDIA's Tegra K1 and the A8X as well. To test this, we use a suite of benchmarks that can give a good idea of real world gaming performance.

3DMark 1.2 Unlimited - Overall

3DMark 1.2 Unlimited - Graphics

3DMark 1.2 Unlimited - Physics

BaseMark X 1.1 - Overall (High Quality)

BaseMark X 1.1 - Dunes (High Quality, Offscreen)

BaseMark X 1.1 - Hangar (High Quality, Offscreen)

BaseMark X 1.1 - Dunes (High Quality, Onscreen)

BaseMark X 1.1 - Hangar (High Quality, Onscreen)

GFXBench 3.0 Manhattan (Onscreen)

GFXBench 3.0 Manhattan (Offscreen)

GFXBench 3.0 T-Rex HD (Onscreen)

GFXBench 3.0 T-Rex HD (Offscreen)

In practice, while we see that the A8X's GPU is extremely close to Nvidia's single Kepler SMX across the board, with the sole exception of 3DMark which seems to be due to the dependencies present in the physics test that dramatically lower the overall score. NVIDIA's Tegra K1 seemed incredible for its GPU performance earlier this year, so it's just as surprising to see Apple successfully rival NVIDIA in this area. Of course, GPU performance is a function of both peak performance and sustained performance, so we'll have to look at the GFXBench battery rundown test to get the full picture here. If Apple can deliver far superior performance and battery life in such a situation, it's pretty clear that the jump to 20nm will be critical to pushing the limits on what's possible in a mobile device.

NAND Performance

As we've seen before on some tablets, poor storage performance can cause major issues with the overall experience as I/O pauses can far exceed just a few frame drops that one might expect from cases of UI lag induced by insufficient performance elsewhere. In order to attempt to quantify this performance we use a custom utility developed by Eric Patno. While such testing is far from a complete look at performance, this can give a rough idea of what to expect.

Internal NAND - Sequential Read

Internal NAND - Sequential Write

Internal NAND - Random Read

Internal NAND - Random Write

Overall, it seems that Apple does quite well on the storage tests. It seems that the iPad Air 2 shares its storage solution with the iPhone 6. While I don't have an iPad Air on hand for testing, it should match quite closely to the iPhone 5s. This represents a generally high-quality NAND solution, but as mentioned before random I/O could stand to improve a bit. Compared to most of the lower-cost Android tablets it's definitely as good as it gets though.

    "Most Android users have no idea.

    ITunes hasn't been required in years."

    Except every ios device has to contact apple to work initially, and either itunes or itunes on the web does this. It's a stupid requirement that apple will never ever let go of.

    You don't have to connect any apple device to iTunes. At all. Ever. You take it out of the box, you turn it on, it asks you a few simple questions and you're on the homescreen.

    What you're talking about is recovery mode. That's the only time I've seen that.

    Google Play Services is what?

    Google's version of "iTunes on the web"...

    Really? That "iTunes on the interwebs" is the most retarded thing I haver have read here... But two pages from this, and anyone can see the real problem of this user...

    And "iTunes on the interwebs" is welcome, makes a stolen iPhone or iPad worthless, wich if cool, unless you plan to stole one.

    As does Samsung (& Google/AT&T/Verizon/Sprint/Carrier)
    As does HTC (& Google/AT&T/Verizon/Sprint/Carrier)
    As does LG (& Google/AT&T/Verizon/Sprint/Carrier)
    As does {insert OEM here} (& Google/AT&T/Verizon/Sprint/Carrier)
    ....and this DOES include the 'Nexus' lineup. While 'stock Android', it's built by and distributed the largest 'data miners' AND exploiters on the Internet, today. Google. Period
    At least with Apple, sure, you definitely 'register' with them ONCE ...From then on, your communication with them is limited by your choices in settings. If title doing nothing wrong, I don't see a reason to help with 'traffic' or a developer improve his app, etc
    If I'm doing something wrong, I suppose I would shit those options off. No need to 'phone home' as EVERY Android device does, including my Note3 I enjoy so much
    At least Apple's a one shot, you choose deal
    In the world of Android, it's a gamble unless you're using Nexus. Then you're 'only' sharing with Google. Everyone else you're dealing with the OEM and the carrier's bloat ...and constant background, unavoidable and incessantly running 'processes'
    Anyway, yeah...TL/DR
    What did you mean with your quotes?
    A) you don't need iTunes EVEN in the beginning to activate your phone. Use a gmail account as your iPhone check in acct
    B)‘Most Android users have no idea'
    This I disagree with. If argue most ARE aware of this lack of necessity for some time now. Bad thing is you don't ..yet you quoted something you clearly don't understsnd, didn't realize and failed to respond with a 'back up' to your complaint(s)
    It's neither a 'stupid requirement'
    And Apple only held on to it so it could sync your phone in an expeditious manner! Wireless, broadbamd and 'clouds' have t been here forever.
    That said, iTunes eats KIES alive. It's definitely the first thing replaced on my Note updates. Music and media management. Unfortunately, one still has to deal with it for OTA updates
    I'll take the iOS 'update' approach (to both apps and full on OS upgrades all day in comparison)
    As akways, ymmv

    Except every Google device has to contact Google to work initially, and all the time thereafter, feeding them yopur usage metrics to make them money. It's a stupid requirement that Google will never ever let go of.

    There we go, fixed that right up.

    Actually you can use an Android device without ever even having a google account. Obviously things like gmail and the play store wont work, but the option is there if you really wanted.
  • akdj - Thursday, November 27, 2014 - link

    No different than Android devices using your Gmail information for 'initial contact'
    There's NO NEED to use iTunes. iTunes on the web. iTunes on your iPhone! There's hundreds of programs to play your media from
    And the 'need' to contact Apple, use iTunes or any of the other BS you've been told a couple dozen times now hasn't been the case since 5.0, right?
    This is 8.1. So over three years have passed

    In all fairness you do need iTunes still. How will you put all your music in an iPad? Maybe you'll say there are other programs out there you can use, but the fact is you still have to sync it and use some sort of program to put your music.

    You have 3,000 songs in your computer. You get an iPad. How are you going to put all that music in your iPad?

    With Android you can just plug it in and drag and drop your music like the tablet is an external drive.

    That being said, Android sucks because it has no tablet apps.

    Android tablets are for the very basics. Documents, email, videos. But for anything else, you need an iPad.

    AirDrop
    Sync via home sharing (playlists)
    Dropbox GDrive OneDrive
    iTunes match up to 25,000 songs with ya, everywhere you go ...just $20/year
    There's Sooo many options to list, no need to 'sync' your media any longer with your computer physically connected. If you're on you're gime network, feel free to send me a line and I'll walk you through.
    All3,00 songs;)

    I'm blown away by the ignorance here
    Wow. You'd think half these comments are being made by someone who's never used an iPhone, an iPad. iOS period. Much less a Mac or iTunes ITSELF, no, you do NOT need to 'plug in' to get yiur music. If you've got a hundred thousand, yes. Because a TB or two won't fit. Then, it's as easy as plug in to .mac or PC, sync managment and check the boxes to sync (playlists, artists, all...whatever).
    A signficantly better media managment system in aggregate than ANY other in the world
    I use Plex. I use Traktor, I edit audio in Audition, video in premier...but like anything else, organization is key. And iTunes has it nailed.
    Kies. Sucks ...,and it's the other AIO organizer forced upon you by the biggest (by a HUGE margin) OEM making Android phones. Samsung.
    As well, since you know so little about iOS, I assume the same is true with iTunes. It's come a VERY long way since you had to 'connect' your iPhone
