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

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.

    Yeah, that happened once and will likely never ever happen again... nice cherry pick there.

    I thought native audio/video file transfer were still restricted to iTunes. Can I put music and Blu-Ray rips on an iOS device and open them with more than one audio/video player?

    What about apps that used to require iTunes to load data in them, can I now just use regular USB?
  • Samus - Friday, November 7, 2014 - link

    I've had an iPhone 4S for over a year, my first Apple product...and it replaced my technically superior but buggy as hell Galaxy S3.

    Still haven't installed iTunes and I've upgraded from IOS 6 through IOS 7 and IOS 8.

    I *almost* installed iTunes to downgrade back to IOS 7 while Apple was still permitting it, but I got used to the...lets just say, lack of smoothness my phone once had.

    I had an HTC Dream (G1) years ago so I'm accustomed to jerky UI's by now.

    The reason I like the iPhone comes down to the app store, the camera, battery life and size. It's really hard to find a <4" phone anymore and the GS3 was just too big for me.

    Google Music Play All Access or whatever mouth full of words its called works fine for audio. I've been wifi transferring video files from any computer on the same network to the VLC app on my iOS device for a couple of years now and haven't had a problem.

    No USBing it over to the device however, but most things use either a cloud back end or wifi transferring for files. I've never had to plug my iPhone or iPad into a computer except to charge it for years now.
  • carloshehe - Sunday, November 9, 2014 - link

    That requires a WiFi set up that people may not have or understand how to do it.

    Its just called Play Music.
  • akdj - Thursday, November 27, 2014 - link

    Play music. Play video. Play magazines. Play books, tones, podcasts, an app tray in alphabetical order, Google Ringtones? (I'm a Note 4 & iPhone owner and enjoy both, honestly!). Your TV shows? Actual app 'layout' on a far superior and quicker rig is quite useful if you're interested in changing your UI. Wifi, no need. NFC is here now and Airdrop destroy NFC when it comes to transferring files from computer to phone, tab or vice versa. No need for a separate wifi zone
    No LTE or data charges apply.
    It seems as though about a ½ billion people understand it, I'm not sure who you're talkng to that doesn't get it. One of the overlooked and most desirable ios feature and strength is it's optimization of hard and software, lack of carrier bloat and the MOST active development community in history. The cool thing, when compared to its counterpart is this Eco system isn't limited to a certain, average sized phone
    Developers take the time to optimize the app for larger dispalys...including the tablet form factor unlike Android (5.0 from the Nexus reviews I've seen)
    As a business owner if 27 years, husband, father and pilot... iOS has literally revolutionized our business's in the past five years
    Mini 2 is my kneeboard, flight planner, fuel calculator, Jep charts and up to date plates, real time weather and traffic, the flight manual for each plane, and it's shaved off 47 of the 48 pounds my flight bag was consistently consuming. One of my son's grades have come up from C+/B- to all As! Due solely to the iPad...it's learning software and compelling nature and new idea of 'learning'. A tutor for the year wouldn't have improved his grades as much and would've doubled the price
    The iPhone 6+ is hand's down the best iPhone to date. I'm not familiar with the 6, as we've been using Notes and the earlier 3.5" & 4" iPhones. It's balance and weight, slim form factor and incredible speed is unparalleled ...my Note 4 screams and looks great. I'm using adaptive screen for adjustments to the saturation but for me, it's the tool we need on site as we produce audio, video and still shots from all over Alaska. We've been lucky enough to work with Nat Geo, Smithsonian and Discovery (several of their subs) and in Alaska, without a plane you're not going to get 99% of her.
    We also provide mobile production and have hosted many hundreds of parties over the past three decades in villages from St George and Paul NW AK and Montague where you CAN see, not Just See Russia, but ice fish if you're crazy enough on their territory. Cool thing ...our snow machines (Alaskan for snowmobile;)) --- to Juneau, Ketchikan, Wrangle, Hoonah, Eek in the southeast. & up and down the Aleutian chain
    None of this would be possible without today's technology. From the Beechcraft and Otter's nav aids and instrumentation for inclement weather to setting a three song ceremony up outdoors and amplifying the official! Ten years ago, burn a CD with the processional, bride's march and recessional we were humping a couple hundred pounds for that fifteen minutes of ceremony
    Today, an iPad, three lavaliere mics and the 45 pound, suitcase Fender 500 ...three minutes TJ break down, maybe ten to put together and we're able to double our bookings as the bigger rigs can now solely be used for the reception ....again, whether 'Play Music' or iTunes on a phone or tablet is an incredible backup to have on hand in these situations --- computer goes down, you're instant on. dJay2, Pinnacle and I can't start the list of incredible DAWS we routineky work with make editing and playlist building a breeze. dJay with a controller is flat amazing as is Traktor, vJay, and the ability to wirelessly control AirPlay to projectors and the GoPro cams with music video mix has landed contracts for our business at five of the seven local high schools and a dozen junior highs. And it's a HELLUVA lot cheaper than buying a smart, moving head, laser system (we've got a both, and plenty of LED ParCans, effects, etc....but video is another level of 'cool' to the younger generation...
    ....Which I think leads me to my point. To those of you 20 something's that grew up connected, with a cell phone and computer...DON'T limit yourself. The Note4 &. Stylus allow me to sketch with structural engineers rigging positions, sign their credit cards with a 'pen' instead of a finger and they're incredibky fast. Wicked fast and a night and day difference between N1&2
    That said, limitarions imposed by Google on 'external' (internal microSD) storage is a JOKE! Always makes me laugh when the Android camp points Apple's pricing on NAND as a 'ripoff' ...IMHO, a ripoff or bargain as I see it, no matter how YOU see it, the 'option' is there. My 'flagship' Noten4 comes in a single size. 32GB, about a third of which isn't available due to the OS
    Then, there's a very arbitrary system of which apps can and can't be moved to the card. Bizarre and getting worse. Note 3 I had if I moved the app, it moved the WHOLE app.
    Now, with 4.4 I'm able to move 'some' third party apps, no AT&T or Samsung bloat to the microSD card. Slower NAND, less storage options and a terrible development community, for me...make the decision easy, especially with the new iOS releases; 6, 6+ and Air2 (WOW, this is another level of badass!)---a second and a ½ generation 64bit SoC, battery/efficiency monsters and mind blowing objective measurements
    And it doesn't end there. There's not a single solitary laptop on the market that can come close to the again, 2 ½ generation rMBP. The 15" I bought in 2012 changed comouting to me. HiDPI display is beyond awesome, the SSD speeds were phenomenal, power was incredible and at 4 pounds and seven hours of usage away from 110 was an absolute JOY!
    I just picked up the recently updated Haswell model witht the PCIe SSDs, the bigger 2GB 750 and Iris Pro (5200---& if you've yet to see the IP5200 in action, go to an Apple Store, Best Buy, wherever and play with it. Again, and as expected an iGPU from Intel that is unreal!
    MSI, Alienware, Clevo....9-12 pound 52 minute gamer monstrosities are a dying breed. Home built desktops for the enthusiast will stick for a while but when the power from a four pound laptop as a 15" 2014 rMBP demonstrates with a TB PCIe storage system, I'm reading and writing right at or just over a Gb/s! The new MP replaced (finally ,in March after waiting a bit) my 2010 octocore and runs circles around it! And I had put the 830s in for SSD, better GPU, didn't matter)
    What Apple's doing today in phones, tabs, lap & desktops is incredible and with iOS 8/OS X 10.10, you're immediately set up with a 'hot spot' for your laptop.
    Metal, elimanting the thick mud of OpenGL ES and allowing developers to work 'right on the metal'. No middle man. Shared cache for the memory so it can simultaneously be accessed but the CPU and GPU as well as continutiy, handoff....and SWIFT! They wrote an entirely new code from scratch, it's incredible and free to learn! Once you've played a bit, grab XCode for free and play around with building your own app, for your use.
    Don't limit yourself to a single choice. No company is worth that type of 'fandom'. It's not football (American or 'real' everywhere else in the world, AKA soccer). It's a phone. A computer. A tablet. Buy wait works for YOU. Not what some DBag online says, your peers are using or based on reviews from sites other than here, ARS....maybe a couple others.
    Once you buy, don't read the comments!

    Yes, you can.

    Most App's you upload files via HTTP, FTP, almost all support AirDrop.

    What about USB syncing?

    Can you only sync a playlist with your android, that you update in your PC, and then auto-syncs the playlist, and the music?

    Can you sync your entire library (or some albums, or some playlist), but transcode your music to a specific bitrate?
  • carloshehe - Sunday, November 9, 2014 - link

    The only way to get music to play in your iPad without plugging it into anything is to use a cloud storage app that plays media.
  • nyastra - Sunday, November 9, 2014 - link

    1) Dropbox, OneDrive, GoogleDrive
    2) Yes - VLC,etc

    Spotify, Amazon
  • akdj - Thursday, November 27, 2014 - link

    No need for USB. We've got AirPlay. No need for iTunes for years. But it's still a killer piece of media management software and runs well, fluently and keeps your crap in a 'third' and physical location If you're looking to save pics, vids, drawings ...projects, whatever, sure there's a lighting to USB adaptor.
    I don't think I remember Ever having to use iTunes to 'load data on them' ...or are you talking about the early days of syncing music and media, etc?
    Regardless, no need. Myself...I orefer DropBox. It's in my finder, toolbar (both on 10.10 and 8.1) and iOS as well as Android. It's an amazing app with excellent reliability and a bill a year to ensure the safety of a TB of data is invaluable.
    Office 365 as well, ten bucks and five TBs Of storage, one formal, three kids, as well, my wife and I! Oh, yeah...it comes with this word editor/text editor, a 'spread sheet' thingy and this pretty slick, not quite keynote wannabe;) --- no, I'm being sarcastic. Five tabs, five computers. XPlatform
    Just Incredible! $20/year per TB of storage.
    Unfortunately it's Windows and therefore not nearly as 'open' or able to be baked into OS X. SkyDrive kicks was on 8.1 though.
