The other big announcement for the day is of course Apple’s new iPads, the iPad Air 2 and the iPad mini 3. As signaled by their names, neither is intended to be a massive departure from their (still for sale) predecessors. But both of them, the iPad Air 2 in particular, pack a number of improvements over the 2013 models.

In-hand, the iPad Air 2 is not as significant a departure from its predecessor as the original Air was from earlier iPads, but if you are familiar with the original Air then you can appreciate the fact that Apple has taken it down from 7.5mm thick to 6.1mm thick. The weight is roughly the same (437g vs. 469g) so it’s not much lighter in the hand, but handling it makes the change in size more apparent.

Perhaps more readily apparent is the anti-reflective coating, a first for an iPad. While Apple’s controlled demo room doesn’t give us the opportunity to introduce too much light, in what testing we could do there’s definitely a difference. Whatever it is that Apple is using, the coating doesn’t seem to have changed the clarity at all; it is seemingly still as clear as the non-coated iPad mini 3.

Meanwhile the A8X inside presents us with a new mystery. This is a new chip, and we know very little about it besides Apple’s claims of 40% better CPU performance and 2.5x better GPU performance. The CPU performance points to a dual core “Enhanced Cyclone” configuration like A8, while the GPU performance number is well in excess of what we saw going from A7 to A8. So comparing A8X to A7, we are most likely (finally) looking at a hex-core Imagination PowerVR GX6650 GPU. However, this alone does not explain where the roughly 1 billion additional transistors compared to A8 have gone. Most likely there are additional surprises to be found.

Moving on, we have the iPad mini 3. Unlike the iPad Air 2, Apple isn’t overhauling the hardware by nearly as much, so the iPad mini 3 is a smaller upgrade over its predecessor than the iPad Air 2 is. Size and weight stay the same, so the new mini feels the same in your hands as the old one. The display is also once more a 2048 x 1536 pixel display, though it did look a bit better than we recall the iPad mini 2’s display being, so it may be a new panel (but this is something we’d need to test).

Apple hasn’t replaced the SoC or WiFi radio – it’s still an A7 and 802.11n respectively – so performance isn’t any different either. What’s left to set apart the new mini from the old then is the inclusion of Apple’s Touch ID sensor along with a larger 128GB storage option. It’s admittedly not much, especially when the iPad mini 2 is now $100 cheaper. On the other hand it is available in Gold, and as we’ve seen with the iPhone that has proven to be a very popular option at launch.

    I'm a bit surprised the iPad mini 3 didn't get the A8 (I wasn't expecting the A8X). Perhaps it got an IGZO screen to improve the color gamut, but the $100 price drops on the 64GB and 128GB and Touch ID might not be enough to prevent cannibalization from the iPhone 6 Plus. Perhaps that's what Apple was thinking, and thus they decided to accept slowing sales of the iPad mini and to focus on price cuts, as well as the more significant improvements in the iPad Air 2.

    Re: last paragraph. My relative has an iPad mini Retina with 128gb. So it's just Touch ID that's new.

    The Apple tax is strong on the mini 3!

    The Windows tax is much worse.

    @melgross I hope you're kidding.

    The most obvious way to get that 40% increase (ie about 15% over the A8) is to drive the A8X at 1.6GHz rather than the 1.4GHz of the A8.
    But I agree where the extra transistors went (apart from the GPU cores) is a mystery. The most obvious guess is a substantially larger L3 --- maybe that's 8MB in size?

    Or it could perform better on benchmarks because it has more RAM. That could explain the extra transistors.

    RAM transistors aren't counted as SoC transistrs.
  • kwrzesien - Friday, October 17, 2014 - link

    The RAM interface connectors might be doubled on the SOC and would count as transistors. But that's not 1B. Besides the additional 2 GPU cores there must be some kind of additional L3/L4 cache or video frame buffer.

    Video RAM?
