This year’s September Apple event has been relatively unusual, not only because of the pandemic and online-only nature of the show, but also because amongst the new hardware releases there’s been an evident lack of a new iPhone at this point in time.

Apple however didn’t disappoint, and managed to showcase brand-new iPads and Apple Watches. Amongst the new tablet line-up, we find the new 8th generation iPad which sees an upgrade in its computing capabilities with the new A12 chip, and the newest iPad Air which sees a total redesign, adopting the design queues of the iPad Pro siblings, and also for the first time introducing the new Apple A14 chipset – the industry’s first 5nm processor.

Starting off with the most exciting tablet today, which is the new iPad Air:

At the heart of the new tablet we find Apple’s newest A14 chip, which is a keystone component of the new generation devices and will also likely power the next generation iPhone once it gets released later this year. Apple’s event disclosures this year were a bit confusing as the company was comparing the new A14 metrics against the A12, given that’s what the previous generation iPad Air had been using until now – we’ll need to add some proper context behind the figures to extrapolate what this means.

On the CPU side of things, Apple is using new generation large performance cores as well as new small power efficient cores, but remains in a 2+4 configuration. Apple here claims a 40% performance boost on the part of the CPUs, although the company doesn’t specify exactly what this metric refers to – is it single-threaded performance? Is it multi-threaded performance? Is it for the large or the small cores?

What we do know though is that it’s in reference to the A12 chipset, and the A13 already had claimed a 20% boost over that generation. Simple arithmetic thus dictates that the A14 would be roughly 16% faster than the A13 if Apple’s performance metric measurements are consistent between generations.

On the GPU side, we also see a similar calculation as Apple claims a 30% performance boost compared to the A12 generation thanks to the new 4-core GPU in the A14. Normalising this against the A13 this would mean only an 8.3% performance boost which is actually quite meagre.

In other areas, Apple is boasting more significant performance jumps such as the new 16-core neural engine which now sports up to 11TOPs inferencing throughput, which is over double the 5TOPs of the A12 and 83% more than the estimated 6TOPs of the A13 neural engine.

Apple does advertise a new image signal processor amongst new features of the SoC, but otherwise the performance metrics (aside from the neural engine) seem rather conservative given the fact that the new chip is boasting 11.8 billion transistors, a 38% generational increase over the A13’s 8.5bn figures.

The one explanation and theory I have is that Apple might have finally pulled back on their excessive peak power draw at the maximum performance states of the CPUs and GPUs, and thus peak performance wouldn’t have seen such a large jump this generation, but favour more sustainable thermal figures. What speaks against such a theory is that Apple made no mention at all of power or power efficiency this generation, which is rather very unusual given they’ve always made a remark in regards to this aspect of the new designs. We’ll have to see if this is indicative of the actual products, of it’s just a side-effect of the new more streamlined presentation style of the event.

Whatever the performance and efficiency figures are, what Apple can boast about is having the industry’s first ever 5nm silicon design. The new TSMC-fabricated A14 thus represents the cutting-edge of semiconductor technology today, and Apple made sure to mention this during the presentation.

Coming back to the iPad Air, the new tablet is a complete redesign for the mid-range device, and now adopts the new design language that had been introduced with the latest iPad Pro models over the last generations. This means a new thinner bezel design and the loss of the home button.

Centre-stage we find a new 10.9” liquid retina IPS LCD panel with a 2360 x 1640 resolution. The panel comes with all bells and whistles you expect from Apple, such as a full lamination manufacturing process to enable better contrast and a “pop-out” feeling, True Tone and a Display P3 colour gamut.

We’re seeing the adoption of the same 12MP 1.22µm pixel sensor as on the recent generation iPad Pro models, sporting a for a tablet relatively large f/1.8 aperture.

Interestingly, because of the removal of the TouchID home button on the tablet, Apple has opted to not just solely rely on Face ID, but to introduce a new fingerprint scanner on the frame of the device. The new capacitive design isn’t exceptionally novel in the industry, however it’s the first time that we see Apple employ such a unit in their products.

Another big noteworthy change in the new iPad Air is the fact that it’s now using a USB-C connector rather than Lightning. Apple here explains that the new connector allows for much faster transfer speeds between more devices. It’s a much welcome addition to the new generation, and we’re still crossing our fingers that Apple will make the same choice on the next-gen iPhone.

8th Generation iPad: A12 Brains Upgrade

Also announced today was Apple’s new 8th generation iPad. The lower-entry tablet here largely retains the specifications of its predecessor when it comes to form-factor, display, cameras and connectivity.

The big improvement for this generation is the move from the A10 chip to the newer A12 generation. Although it’s not the newest silicon, at this price range the upgrade represents a massive performance boost, and now it means that even the lowest-end iPad supports high-performance machine learning through the inclusion of the Neural Engine.

$599+ for the iPad Air, $329 for the iPad

The new iPad Air will commence at $599 which is an uptick in terms of price range compared to its predecessor. The upgrade from 64GB to 256GB storage costs an extra $130, whilst cellular LTE connectivity over the basic Wi-Fi models costs an extra $150 as well. Oddly enough, availability of the iPad Air will only start in October, which is unusual for an Apple launch.

The 8th generation iPad starts at the same prices as the 7th gen, meaning $329 for the basic 32GB Wi-Fi model, with an extra $130 for the 128GB variant, and an extra $100 for cellular connectivity. Availability for the new iPad starts this Friday the 18th.

    What's the use case of needing so much performance on a tablet?
    With that price range, they shouldn't be comparing it to low-end Chromnebooks, but rather Ryzen 7 laptops...

    A tablet can easily transition to a "desktop mode" by connecting it to a monitor and a keyboard. Now, if for some invalid reason, tablet manufacturers limit a universal connectivity, or software utilization , it is a completely different story.Modern tablets could enable you to carry with you, your desktop everywhere. And yes , they are powerful enough for this purpose, now.

    That said comparing mobile to desktop chips, must be the secret all know and no-one admits publicly. Letting alone that mobile products are one or sometimes two node processes ahead, how can you start saying they are equal when it is quite certain that after 30 to 60 mins mobile chips will throttle due to heat accumulation?
    Second , both single and multi-core frequencies are about 70% higher in desktop-laptop. Assuming same instructions per cycle(I very much doubt they are equal , but anyway), desktop and laptop processors have a theoretical 50 to 70% more performance(quite probably, more, because of higher IPC). But their real world performance is still better than the mobile, because they can sustain a certain load almost indefinitely and at higher frequencies because of active cooling. So, that in practice their single core performance is actually closer X2 and their multicore closer to x20 and all that on inferior node tech.

    So , there you go , having the geekbench sprout where it should not, to create confusion and get consumers to buy , admittedly increasingly powerful chips, but still a great distance from similarly priced or cheaper desktop products.
    Not only that, the whole philosophy is such , the end-user will never take advantage of their computational prowess because they are designed from the get go as data consuming and lifestyle
    devices.

    Don't forget the camera! $100 for a fingerprint reader AND and extra 4MP, a stop of light gathering capability, and slow-mo video. On a tablet. Why, by Apple standards, it's positively a bargain. 😐 Reply

    And removal of the headphone jack on a media consumption device. Yet another stupid decision... yes Bluetooth is an option but it’s another thing to charge and can add latency. A USB C adapter blocks the port for charging and adapters get in the way (for gaming) because it’s in the middle of the tablet... Reply

    No headphone jack is a deal breaker. Pass Reply

    Seriously, what excuse do they have for not putting a fingerprint sensor on a tablet. They basically lost the education market doing this. Reply

    Not having a headphone jack and a fingerprint sensor are strange and bad, but I also wondered what Apple's obsession with crappy LCD screens is.

    I prefer dark backgrounds, and due to the way LCD screens work that's a constant power drain that's really unhelpful in Tablets. Aside from generally looking worse. At least iPads tend to have good color balance?

    If you're a student, they'll give you free AirPods to lose down the back of your sofa. Reply

    Honestly totally stupid decision on a media-focussed device. You can possibly argue it on the iPad Pro (but not really), on the Air it’s a deliberate money-grab. Reply
