Today Apple held its fall 2021 iPhone launch event, and we’ve gotten 4 new iPhones from the new iPhone 13 series: the iPhone 13 mini, the iPhone 13, iPhone 13 Pro and iPhone 13 Pro Max. This year’s phones follow last year’s rather large generational upgrades – although this year Apple also has quite a few big features on the menu such as better cameras and new much improved 120Hz displays on the Pro models. Battery life also has seen a larger emphasis, with Apple claiming the new iPhones last longer than their predecessors, achieved through both component efficiency improvements as well as new larger batteries.

It’s also where we see Apple’s newest A15 chip: Years been in the focus of the industry, the new SoC promises iterative improvements, with some of Apple’s claims being a little eye-brow raising, more on this in a bit.

Let’s go over the various specifications of the new device set:

Starting off with the new internals, the new iPhone 13 series are powered by Apple’s newest A15 Bionic SoC. Like last year, the A15 is manufactured on a 5nm process node. Apple naturally doesn’t specify exactly which variant of node it is, but given the timing and the evolution of TSMC’s offering, we suspect it will be on the new N5P node, which is an iteration on last year’s N5 node.

The new design follows Apple’s 2+4 CPU configuration that we’ve seen being used for the last couple of generations. We’re looking at two new performance cores and four new efficiency cores. Apple this year didn’t disclose too much information about the new CPU, most notably, the company refrained from making generational comparisons to the predecessor A14 chip, instead opting to compare itself to the competition, again something that we don’t see Apple do much in their silicon talks.

Here, they’re claiming that the new A15 will be +50% better than the next-best competitor. The next-best competitor is Qualcomm’s Snapdragon 888 – if we look up our benchmark result set, we can see that the A14 is +41% more performant than the Snapdragon 888 in SPECint2017 – for the A15 to grow that gap to 50% it really would only need to be roughly 6% faster than the A14, which is indeed not a very large upgrade. Apple also didn’t comment on any new ISA features such as Armv9/SVE2, so it seems that the CPU doesn’t feature it?

Back in early 2019, Apple had lost their lead architect (Gerard Williams III) and a portion of their CPU design team when several of the team went on to found and work at Nuvia, which was acquired earlier this year by Qualcomm. While I’m not certain, the time gap here certainly could match and the new CPU time to market, and be the first signs of that talent loss and team reshuffle. As a note, Apple went on to hire Arm’s lead architect Mike Filippo, likely working on a new CPU family.

Another theory is that Apple decided to focus more on reducing power and energy efficiency this generation, given their massive lead in CPU performance. This actually would be a much more welcome theory, but one that we won’t be able to confirm until we get our hands on devices.

What was even more weird, was the fact that the A15 is the first SoC where Apple has decided to bin into two different performance models. The regular iPhone 13 mini and iPhone 13 are receiving an A15 with 4-core GPUs, while the Pro models are receiving a 5-core GPU configuration. In fact, if I’m not wrong, this would be the first time ever we see a functional block binned SoC in a mobile phone at all, as I don’t remember any company ever doing this before today (Normally mobile SoCs are power binned).

GFXBench Aztec Ruins - Normal - Vulkan/Metal - Off-screen

For the lower performance 4-core GPU model, Apple again was weird with their performance predictions as they focused on the competition, and not the generational gains. The improvements here over the currently best performing competitor is said to be +30%. Taking GFXBench Aztec as a baseline, we see the A14 was around +18% faster than the Snapdragon 888. The slower A15 would need to be +10% faster than the A14 to get to that margin.

The faster 5-core A15 is advertised as being +50% faster than the competition, this would actually be a more sizeable +28% performance improvement over the A14 and would be more in line with Apple’s generational gains over the last few years.

Of course, all these figures are just speculation for now, as we don’t know exactly what workloads Apple references to, and there are quite larger variations that can be measured. We’ll have to verify things on actual devices.

Apple noted a lot of other SoC-side improvements, such as making mention that they’ve doubled the system level cache (SLC) to what presumably would be 32MB. There’s also a new display engine, likely to deal with 120Hz, and new video decoders and encoders – I wonder what kind of format they support now; Apple did mention hardware ProRes support.

Finally, the Neural Engine boosts its performance to 15.8TOPs over 11 TOPs, even though it still features the same 16 core count.

One thing we missed being mention from Apple is whether the new SoC uses new memory or not. We’ve seen adoption of LPDDR5 in the market, and the A14 notably lacked this. If the A15 also didn’t have it, that would be quite weird.

Similar Design, But Refined

The new iPhones follow up on the industrial design introduced with the iPhone 12 series last year. This means the similar flat-edges and metallic finish.

The only two distinguishing visual changes of the iPhone 13 mini and iPhone 13 is the fact that the dual-cameras are now oriented diagonally, rather than vertically, and on the front side of the phone the new notch is 20% smaller.

The fact that Apple still continued with a notch rather than a more modern design is likely to be controversial and some will make fun of Apple, given the competition’s rapid design iterations and experience with hole-punch or under-display cameras, but Apple has never been very adventurous in the design department.

The normal and mini models have had their display characteristics boosted to match those of the iPhone 13 Pro models last year, and what this likely means is that those models have moved to a higher tier panel with the newer OLED emitters.

The iPhone 13 Pro and Pro Max are in turn moving to display panels to a tier higher than last year’s Pro models. The new features here are focused around the new variable refresh rate 120Hz panel, which is able to dynamically switch between 10 and 120Hz depending on content. It’s likely the same type of LTPO technology that we’ve seen earlier this year with the Galaxy S21 Ultra, and should bring significant battery life increases and smoothness to the Pro models. Brightness also has gone up to 1000nits.

Apple stated that all new models feature a new internal component arrangement, allowing for better footprint usage within the phone, and allowing for more space for the batteries as well as the camera system.

Apple quoted figures such as +1.5h for the iPhone 13 mini, +2.5h for the iPhone 13, +1.5h for the iPhone 13 Pro, and +2.5h for the iPhone 13 Pro Max, all relative to their predecessors.

While Apple typically doesn’t state absolute battery capacities, we’re seeing weight of the phones go up; 135g -> 141g, 164g -> 174g, 189g -> 204g, and 228g -> 240g. Particularly the Pro models are getting extremely heavy, so I do question Apple’s insistence on steel frames here.

New Cameras Everywhere

The camera setup on the new iPhone 13 line is all new, on all models. Although the types of cameras haven’t changed, still ultra-wide, wide and telephoto where applicable, we’re seeing new sensors and modules on all units.

The iPhone 13 and mini feature a dual-camera setup. The main module here has received a new sensor, still 12MP (valid for all modules on all models), however increases in size and thus also in pixel pitch from 1.4µm to 1.7µm. The optics are 26mm equivalent, with an f/1.6 aperture. In terms of stabilisation, Apple has moved from OIS to an IBIS system, or what they call sensor-shift image stabilisation, where instead of the optics, the sensor itself is stabilised.

The ultra-wide angle is similar, with a large 120° field of view at 13mm focal length equivalent and f/2.4 optics, but Apple does say it’s a new faster sensor, even though it’s not larger.

The Pro models have seen larger camera updates, in the literal sense. This year’s Pro models feature a much larger camera island, and a visibly larger camera lenses and thicker camera bumps.

The main sensor is again upgraded to a larger size, this time with 1.9µm pitch pixels, which at 12MP translates to a 1/1.67” sensor – still not quite as large as what we see from some Android vendors. The aperture is a large f/1.5, and is also stabilised via IBIS.

The ultra-wide does not appear to have a different sensor on the Pro models, however Apple takes advantage of the thicker module size to enable a much wider f/1.8 aperture.

Finally, the telephoto module comes in at a 77mm equivalent focal length, or 2.96x magnification over the wide module. Apple didn’t comment on the pixel size so we can’t infer sensor size, but aperture is a bit smaller at f/2.8.

I just want to note that I’m happy Apple has retained the same camera setup on the regular Pro and the Pro Max models – something they didn’t do on last year’s models, and which also many other competitors fail to do between their differently sized flagships, it means you’re not missing out on features just because you chose the smaller variant.

In terms of software photography prowess, the new phones features Smart HDR 4, promising further improvements to tone-mapping and retention of shadow and highlight details, as well as now finally improving night mode to work on all modules (The telephoto previously didn’t have the feature).

There are also new features such as stylisation of pictures, a filter effect that works within the imaging pipeline rather than a post-processing effect. Video recording gets a new Cinematic Mode feature for cinematic looking focus pulls and shifting, enabled automatically in the app via ML and subject tracking, as well as ProRes video recording.

Static Pricing, Better Phones

The new iPhones are much improved this year, with a larger focus on displays, battery life, and camera quality. Performance metrics were a bit vague this time around, so we’ll have to see whether Apple here has invested into power efficiency, or indeed slowed down in progress.

On the positive side, all new models now start at the same pricing as their predecessors, and the regular iPhone 13 and mini now start at a 128GB baseline storage model, and doubling up the options stack. The Pro models have the same pricing this year, however add in a super-premium 1TB storage option at a higher price category.

The phones will be available for preorder this Friday, with availability September 24th.

    The battery life numbers provided are confusing. The iPhone 13 gets 2.5 more form 12 and 13 Pro gets 1.5 more than 12 Pro (which is the same as 12 and maybe even a bit less due to 6GB RAM ?). Eg. 13 last longer than 13 Pro
    The video playback numbers they provided jump a lot more with the pro phone having a larger increment.
    And according to the stream the 13 Pro and 13 are quite different on the inside unlike 12 and 12 Pro.

    Probably due to the 120Hz display. It would still be pretty impressive if they manage to improve battery life while adopting a HRR display. Reply

    The ProMotion is variable refresh, only kicking into 120Hz when motion is detected on the screen. So it's conceivable that it's not super battery intensive if it drops down to 10 or even 1Hz on static screens. Hard to tell with how apple never providing battery capacity though. Reply
  • mattbe - Wednesday, September 15, 2021 - link

    They already said that 10hz is the lower range.
    https://www.phonearena.com/news/apple-first-120hz-...

    I am not even sure how well 10hz will works due to a potential problem with flickering. Hope it's not an issue.

    I agree that the performance claims were quite poor, although they did the same thing last year with the A14.
    Based on Apple's own comparisons it doesn't seem there is much of an improvement CPU wise, and a decent improvement in GPU.
    In the iPad Air, going from A12 -> A14, Apple claimed +40% CPU and +30% GPU.
    In the iPad mini, going from A12 -> A15 (5 core GPU), Apple claimed +40% CPU and +80% GPU.
    Maybe the reason for the poor CPU improvements is because of the move to ARMv9, adapting the CPU cores to the new ISA instead of improving them. It would be quite weird that they didn't mention it at all, though Apple being Apple not entirely impossible.
    Either way, we'll have to wait for the deep dive. Looking forward to it.

    Apple is usually very conservative with performance claims though. Wait for benchmarks.

    Also, We are at a point where CPU performance on the iPhone is more than enough. They chose to improve the GPU and neural engine more. Much of the new features depend heavily on the neural engine rather than the CPU.

    Yet these CPU cores will also be used in MacBooks, Mac Pros, etc.

    Unless we see Apple going out of left-field and developing one architecture for mobile vs one for desktops, architectures do need to improve YoY.

    AFAIK not "these" CPU cores but CPU cores of the same arhitecture. Reply
  • MetaCube - Thursday, September 16, 2021 - link

    The M1 literally uses the same cores as the A14 Reply
  • BillBear - Wednesday, September 15, 2021 - link

    A redesign that improves power efficiency instead of focusing on raw performance is really what is called for, since we've already run into the handheld device thermal wall.

    As for Macs, we're moving towards designs that pack many cores together, so power efficiency will be important there as well.

    Go back and look at the battery life issues the Pixel 4 had when they adopted a 90Hz refresh rate (even though the higher refresh rate was mostly off by default) and the number of hours of battery life you gave up on Samsung's Galaxy line when you turned high refresh rates on.

    You quickly see how cutting power elsewhere is important.
