A few weeks back, it was reported that Apple was exploring investing in OpenAI, the company that makes ChatGPT, the GPT model, and other popular generative AI products. Now, a new report from The Wall Street Journal claims that Apple has abandoned those plans.
The article simply says Apple “fell out of the talks to join the round.” The round is expected to close in a week or so and may raise as much as $6.5 billion for the growing Silicon Valley company. Had Apple gone through with the move, it would have been a rare event—though not completely unprecedented—for Apple to invest in another company that size.
OpenAI is still expected to raise the funds it seeks from other sources. The report claims Microsoft is expected to invest around $1 billion in this round. Microsoft has already invested substantial sums in OpenAI, whose GPT models power Microsoft AI tools like Copilot and Bing chat.
Nvidia is also a likely major investor in this round.
Apple will soon offer limited ChatGPT integration in an upcoming iOS update, though it plans to support additional models like Google’s Gemini further down the line, offering users a choice similar to how they pick a default search engine or web browser.
OpenAI has been on a successful tear with its products and models, establishing itself as a leader in the rapidly growing industry. However, it has also been beset by drama and controversy—most recently, some key leaders at OpenAI departed the company abruptly, and it shifted its focus from a research-focused organization that was beholden to a nonprofit, to a for-profit company under CEO Sam Altman. Also, former Apple design lead Jony Ive is confirmed to be working on a new AI product of some kind.
But The Wall Street Journal did not specify which (if any) of these facts are reasons why Apple chose to back out of the investment.

For the past few years, Apple has been making big-budget movies meant to compete with the best traditional Hollywood studios have to offer, and it has been releasing them in theaters to drive ticket sales and awards buzz.
Much of that is about to change, according to a report from Bloomberg. The article claims that Apple is “rethinking its movie strategy” after several box office misfires, like Argylle and Napoleon.
It has already canceled the wide theatrical release of one of its tent pole movies, the George Clooney and Brad Pitt-led Wolfs. Most other upcoming big-budget movies from Apple will be released in just a few theaters, suggesting the plan is simple to ensure continued awards eligibility but not to put butts in seats.
Further, Apple plans to move away from super-budget films and to focus its portfolio on a dozen films a year at lower budgets. Just one major big-budget film is planned to get a wide theatrical release: F1. How that one performs could inform future changes to Apple’s strategy.
The report notes that Apple is not the only streamer changing its strategy. Netflix is reducing costs and bringing more movie production in-house, while Amazon is trying (so far unsuccessfully) to produce a higher volume of movies annually, but with a mixture of online-only and in-theater releases. It also points out that movie theater chains are feeling ever more financial pressure, as overall ticket sales haven’t matched their pre-pandemic levels despite occasional hits like Inside Out 2 and Deadpool & Wolverine.
Cinemas have been counting on streamers like Netflix and Apple to crank out films, but those hopes may be dashed if the media companies continue to pull back. For the most part, tech companies like Apple and Amazon have had better luck gaining buzz with television series than with feature films.
iFixit has published teardown views for the iPhone 16 and iPhone 16 Pro, along with their larger cousins, the Plus and Pro Max.
The videos are really marketing for iFixit’s various repair kits and other tools and products that you can buy—and sometimes these videos now have lengthy plugs for some new product or another—but nonetheless, the videos almost always include interesting insights about devices’ components.
Tearing down the iPhone 16, iFixit confirmed one thing we already suspected: One of the mmWave antennas was removed and replaced in that same spot by the Camera Control button. It also found that the camera systems in the 16 Pro and 16 Pro Max are almost interchangeable, but sadly aren’t because of the placement of a single screw and the length of a single cable. Too bad.
The disassembly process for the Pro phones is mostly the same as before, but thankfully, there’s been a redesign that reduces the risk of damaging the OLED panel when tearing the phone down.
The biggest discovery was that the iPhone 16 and iPhone 16 Plus have a superior battery replacement process compared to earlier phones. Instead of pull tabs, they use an adhesive that lets go when affected by an electric current.
iFixit says this is one of the easiest battery removal processes in the industry, which is high praise, especially when it’s directed toward a company with a difficult record on that front.
iFixit’s iPhone 16 Pro and 16 Pro Max teardown.
Unfortunately, the 16 Pro and 16 Pro Max haven’t moved to the new battery replacement process found in the 16 and 16 Plus. On the bright side, it’s much easier to service the USB-C port than before, though Apple doesn’t sell that part separately.
iFixit gave all the new iPhones a 7 out of 10 repairability score, which is historically high for an iPhone.
The videos go into much more detail, so check them out.

Andrew Cunningham
This past weekend, I said goodbye to Apple’s 4.7-inch iPhone 6 design after 10 long years.
It started with the iPhone 6 itself in 2014, a long-awaited screen size upgrade for the iPhone (some of the 2011-era Apple punditry insisting that 3.5 inches was the functionally perfect size for a phone screen and that Apple would never, ever change it, is an interesting time capsule). It ends with my wife’s third-generation iPhone SE, its battery capacity already collapsing, which I replaced with an iPhone 16 on Friday.
There are huge differences between those two phones—eight years’ worth of spec upgrades and water resistance being the most significant—but they look and feel almost the same, and things that were fine or forgivable in 2014 have become harder to live with now.
What follows is less a celebration of the iPhone 6 design’s long life and more of a good riddance. It’s not that we never had any good times together, iPhone 6 design, but after a half-dozen versions of you, I think it is time for both of us to move on. Consider it catharsis—and maybe if someone in your life is still rocking an iPhone 8 or iPhone SE, it will be cathartic for you, too.
Battery capacity
Battery life was always an Achilles heel of this phone’s design—the battery had to fight with every other component in the phone for relatively little space, and as a result, it was always exceptionally hard to make it through a full day on a single charge. A portable battery pack or some kind of midday charge was almost always necessary, especially if I had deigned to use a power-hungry feature like Personal Hotspot.
And more charging means putting more cycles on the battery, which over a couple years of ownership makes the mediocre battery life even worse. The battery life in my first “modern”-style iPhone—an iPhone XR, in 2018—was a revelation after years with the 6, 6S, and 8, and since then, I’ve found my iPhone 13 Pro and 15 Pro to be similarly capable of making it to the end of the day with some battery to spare.
Those curves—specifically, those curved edges
Enlarge/ Goodbye, gap between the edge of the protector and the edge of the screen! Goodbye, little air bubbles!
Andrew Cunningham
I put all of our phones in screen protectors and cases, despite usually also springing for AppleCare+. Especially when you’ve got a kid, it’s worth it not to have to worry about every little drop or bump, and they’re good for the resale value, too.
One thing about the iPhone 6-era design was its curved edges, including a subtle curve all the way around the edge of the screen. Over many years with this phone’s design, I have slowly come to hate this subtle curve—screen protectors either fail to make contact with the screen all the way around its perimeter, leaving annoying visible air bubbles, or they do make contact on the flat part of the screen while leaving the curved edges of the glass unprotected. The small ridge created by the screen protector ends up being a trap for dust and other little bits of detritus.
Apple returned to an all-flat-edges design with the iPhone 12 in 2020, reverting to what had been the norm with the iPhone 4 and 5 design. On a flat slab of glass, the additional layer of a thin glass screen protector is nearly invisible when you apply it right, being careful not to trap any dust between a freshly cleaned screen and the protector (my wife goes through roughly one screen protector every three or four months; I have become adept at this dance). It’s nice to be able to guard against scratches and cracks without having to look at and think about it all the time.
And if you’re not the case-and-screen-protector type? One of those “I have AppleCare so I don’t need a case” people? The curved edges of the iPhone 6-era design made the phones more slippery and harder to hold. I thought that was even more true for the iPhone 8/SE version of the design, which switched from an aluminum back to a glass back to enable wireless charging support.
Enlarge/ Control Center has a whole new customization interface.
Samuel Axon
iOS 18 launched this week, and while its flagship feature (Apple Intelligence) is still forthcoming, the new OS included two significant new buckets of customization: the home screen and Control Center.
We talked about home screen a few days ago, so for our next step in our series on iOS 18, it’s now time to turn our attention to the new ways you can adjust the Control Center to your liking. While we’re at it, we’ll assess a few other features meant to make iOS more powerful and more efficient for power users.
This is by no means the most significant update for power users Apple has released of the iPhone operating system—there’s nothing like Shortcuts, for example, or the introduction of the Files app a few years ago. But with the increasingly expensive iPhone Pro models, Apple still seems to be trying to make the case that you’ll be able to do more with your phone than you used to.
Let’s start with Control Center, then dive into iCloud, Files, external drives, and hidden and locked apps.
A revamped Control Center
Control Center might not be the flashiest corner of iOS, but when Apple adds more functionality and flexibility to a panel that by default can be accessed with a single gesture from anywhere in the operating system—including inside third-party apps—that has the potential to be a big move for how usable and efficient the iPhone can be.
That seems to be the intention with a notable control center revamp in iOS 18. Visually, it mostly looks similar to what we had in iOS 17, but it’s now paginated and customizable, with a much wider variety of available controls. That includes the option for third-party apps to offer controls for the first time. Additionally, Apple lets you add Shortcuts to Control Center, which has the potential to be immensely powerful for those who want to get that deep into things.
When you invoke it (still by swiping down from the upper-right corner of the screen on modern iPhones and iPads), it will mostly look similar to before, but you’ll notice a few additional elements on screen, including:
A “+” sign in the top-left corner: This launches a customization menu for reordering and resizing the controls
A power icon in the top-right corner: Holding this brings up iOS’s swipe-to-power-off screen.
Three icons along the right side of the screen: A heart, a music symbol, and a wireless connectivity symbol
Control center is now paginated
The three icons on the right represent the three pages Control Center now starts with, and they’re just the beginning. You can add more pages if you wish.
Swiping up and down on any empty part of Control Center moves between the pages. The first page (the one represented by a heart) houses all the controls that were in the older version of Control Center. You can customize what’s here as much as you want.
The first page resembles the old Control Center, but with more customization.
Samuel Axon
By default, the second page houses a large “Now Playing” music and audio widget with AirPlay controls.
Samuel Axon
The third has a tall widget with a bunch of connectivity toggles.
Samuel Axon
Adding a new page gives you a grid to add custom control selections to.
Samuel Axon
The second page by default includes a large “currently playing” music and audio widget alongside AirPlay controls, and the third is a one-stop shop for toggling connectivity features like Wi-Fi, Bluetooth, cellular, AirDrop, airplane mode, and whichever VPN you’re using.
This new paginated approach might seem like it introduces an extra step to get to some controls, but it’s necessary because there are so many more controls you can add now—far more than will fit on a single page.
Customizing pages and controls
If you prefer the way things were, you can remove a page completely by removing all the controls housed in it. You can add more pages if you want, or you can tweak the existing pages to be anything you want them to be.
Whereas you previously had to go into the Settings app to change what controls are included, you can now do this directly from Control Center in one of two ways: you can either tap the aforementioned plus icon, or you can long-press on any empty space in Control Center to enter customization mode.
In this view, you’re presented with a grid of circular spots where controls can go. Each control that’s already there has a “-“ button in its corner that you can tap to remove it. To move a control, you just long press on it for a split second and drag it to whichever spot in the grid you want it to live in.
This is the Control Center customization view, which is vastly superior to the home screen’s wiggle mode.
Samuel Axon
Choosing to add a new control brings up this long, searchable, scrollable list of controls from both Apple and third-party apps you have installed.
Samuel Axon
There aren’t a ton of third-party controls yet, but here are a few examples.
Samuel Axon
You can resize controls, but most of them just seem to take up more space and include some text—not very helpful, if you ask me.
Samuel Axon
There’s also a marker on the bottom-right corner of each control that you can touch and drag to increase the size of the control. The substantial majority of these controls don’t offer anything of value when you make them bigger, though, which is both strange and a missed opportunity.
To add a new control, you tap the words “Add a control” at the bottom of the screen, which are only visible in this customization mode. This brings up a vertically scrollable list of all the controls available, with a search field at the top. The controls appear in the list just as they would in Control Center, which is great for previewing your choice.

Andrew Cunningham
Apple’s newest iPhones and Apple Watches don’t come out until later this week, but the rumor mill is already indicating that Apple is planning a product announcement for October to refresh some of the products that didn’t get a mention at the iPhone event. Apple scheduled its release calendar similarly last year, when it announced and released new iPhones in September and then launched the first wave of M3 Macs around Halloween.
Bloomberg’s Mark Gurman believes that the event will mainly focus on the first wave of Macs with M4 processors, following the standard M4’s introduction in the iPad Pro earlier this year. As he has reported previously, he expects new MacBook Pro models with the M4 and “pro-level M4 chip options,” presumably the M4 Pro and M4 Max. He also expects an M4 version of the 24-inch iMac.
But the most interesting of the new Macs will still be the redesigned Mac mini, which hasn’t gotten an M3 update at all and has been using the same basic external design since 2010. This Mac mini is said to be closer in size to the Apple TV than the current mini, but still uses an internal power supply so that owners won’t have to wrangle a power brick. At least some of the current device’s ports will be replaced by USB-C and/or Thunderbolt ports, something that MacRumors apparently confirmed earlier today when they found a reference to an “Apple silicon Mac mini (5 ports)” in an Apple software update (some of those ports are reportedly on the front of the device, a nice Mac Studio design upgrade that I’d like to see on a new Mac mini).
The “five port” descriptor does imply that there will be another model with either more or fewer ports—Apple used similar terminology to distinguish the two- and four-port versions of some MacBook Pro models in the Intel days. The current M2 Mac mini models have fewer ports than the models with the M2 Pro chip, because the more powerful processor also has more I/O capabilities—assuming we get one Mac mini with an M4 and an upgraded model with an M4 Pro, we’d expect the Pro version to have more ports.
Gurman says that other Mac models, including the Mac Studio, Mac Pro, and MacBook Air, will see M4-series updates throughout 2025. Of those, the Mac Studio and the Mac Pro have gone the longest without an update—they’re all still using M2-series chips.
Apple is also said to be planning some new lower-end iPads for the October event—not the first time that Macs and iPads have shared billing for one of these late-fall product announcements. The $349 iPad 10 and the iPad mini have both gone over a year without any kind of hardware update; it seems likely that they’ll both get newer chips, if not significantly updated designs.

The future of inter-OS mobile messaging is here, it’s just unevenly distributed.
With iOS 18, Apple has made it possible for non-Apple phones to message with iPhones through Rich Communication Services (RCS). This grants upgrades from standard SMS text messages, like read receipts, easier and higher-quality media sending, typing indicators, and emoji/response compatibility. More than that, it allows for messaging while on Wi-Fi without cellular services and makes group messages far less painful to navigate and leave. Notably, RCS messages between iPhones and non-iPhones will not be encrypted, like Apple’s private iMessage service available exclusively between Apple devices.
iOS 18 makes these RCS upgrades possible, but certainly not guaranteed, at least as of today. Lots of people have already been enjoying cross-platform RCS messaging when texting with iOS 18 beta users. And iPhones on the big carriers’ plans can now trade RCS with Android users. But some iPhone users, particularly on mobile virtual network operators (MVNOs)—typically pre-paid services that do not own network hardware but resell major carrier access—do not have an RCS option available to them yet.
Google, a major proponent of Apple adopting RCS, confirmed to Ars that Google Fi, its own MVNO cellular service, does not, as of this writing, offer RCS chat for iPhone users on Fi messaging with Android users. Android users on Google Fi can use RCS with iPhones on other carriers, so long as that iPhone has “RCS interoperability enabled.”
Reading between the lines, you might conclude that Google is waiting on Apple to enable RCS on a network-by-network basis, both for Fi and for Android users at large. And a Google spokesperson would suggest that is correct.
“We have been working for a long time to accelerate the adoption of RCS, and are excited that Apple is taking steps to adopt RCS with the launch of iOS 18,” a Google spokesperson said in a statement. “Only Apple has the ability to enable RCS interoperability for iPhone users on Fi, and our hope is that they will do so in the near future.”
Ars has contacted Apple, along with carriers Mint Mobile and Boost Mobile, for comment on RCS availability across carriers and will update this post with new information. Some customers of MVNOs offered by the major carriers themselves, like those on Visible from Verizon, have reported having RCS access with iOS 18 installed.
Apple got the message, kept it green
Users of other MVNOs have asked on Reddit why their upgrade from basic SMS to RCS did not occur during the iOS 18 betas. A co-founder and current CFO of Mint Mobile said on September 9 that it would “be a few months, unfortunately,” as the “backend transition is taking some time… Believe me, we want this out as soon as we can,” wrote Rizwan Kassim.
A moderator for the Mint Mobile subreddit suggested that the backend transition involves carriers setting up a relay API for messages, adding that to the “carrier bundle” they deliver to customers and then providing Apple with information it can add to a future iOS update.
If you have an iPhone that isn’t on one of the major carriers’ primary plans (AT&T, T-Mobile, or Verizon) and want to check if RCS should be available, you can do that in Settings. Head to General, choose About, and scroll down to the Carrier line under your active SIM or eSIM. Tap the “Carrier” line until you see “IMS Status.” If it reads “Voice & SMS,” you don’t have RCS yet, but if you see “Voice, SMS & RCS,” you do.
The version of RCS that iPhone and Android users might use now, or soon, is the “RCS Universal Profile,” which does not include the encryption that Google’s own messaging apps provide over RCS. Google’s “Get the Message” campaign tried to shame Apple into adopting RCS. The related site notes that “Apple is starting to #GetTheMessage” with RCS adoption but that iPhone users will have to “check with your carrier” to turn on the feature.
Today is the official release date for the public versions of iOS 18, iPadOS 18, macOS 15 Sequoia, and a scad of other Apple software updates, the foundation that Apple will use for Apple Intelligence and whatever other features it wants to add between now and next year’s Worldwide Developers Conference in June. But for those who value stability and reliability over new features, you may not be excited to update to a new operating system with a version number ending in “0.”
For those of you who prefer to wait for a couple of bugfix updates before installing new stuff, Apple is also releasing security-only updates for a bunch of its (now) last-generation operating systems today. The iOS 17.7, iPadOS 17.7, and macOS 14.7 updates are either available now or should be shortly, along with a security update for 2022’s macOS 13 Ventura. An updated version of Safari 18 that runs on both macOS 13 and 14 should be available soon, though as of this writing is doesn’t appear to be available yet.
Apple has historically been pretty good about providing security updates to older macOS releases—you can expect them for about two years after the operating system is replaced by a newer version. But for iOS and iPadOS, the company used to stop updating older versions entirely after releasing a new one. This changed back in 2021, when Apple decided to start providing some security-only updates to older iOS versions to help people who were worried about installing an all-new potentially buggy OS upgrade.
Eventually, iOS and iPadOS users will need to install iOS 18 and iPadOS 18 to keep getting security updates. But for the handful of older iPads that can’t run iPadOS 18, Apple will usually keep supporting those specific devices with security updates for a year or two. Apple was still providing new security updates for 2022’s iOS 16 as recently as August, keeping older devices like the iPhone 8 and the first-generation iPad Pros reasonably secure even though they were incapable of running newer operating systems.
The macOS 15 Sequoia update will inevitably be known as “the AI one” in retrospect, introducing, as it does, the first wave of “Apple Intelligence” features.
That’s funny because none of that stuff is actually ready for the 15.0 release that’s coming out today. A lot of it is coming “later this fall” in the 15.1 update, which Apple has been testing entirely separately from the 15.0 betas for weeks now. Some of it won’t be ready until after that—rumors say image generation won’t be ready until the end of the year—but in any case, none of it is ready for public consumption yet.
But the AI-free 15.0 release does give us a chance to evaluate all of the non-AI additions to macOS this year. Apple Intelligence is sucking up a lot of the media oxygen, but in most other ways, this is a typical 2020s-era macOS release, with one or two headliners, several quality-of-life tweaks, and some sparsely documented under-the-hood stuff that will subtly change how you experience the operating system.
The AI-free version of the operating system is also the one that all users of the remaining Intel Macs will be using, since all of the Apple Intelligence features require Apple Silicon. Most of the Intel Macs that ran last year’s Sonoma release will run Sequoia this year—the first time this has happened since 2019—but the difference between the same macOS version running on different CPUs will be wider than it has been. It’s a clear indicator that the Intel Mac era is drawing to a close, even if support hasn’t totally ended just yet.
Enlarge/ Emojipedia sample images of the new Unicode 16.0 emoji.
The Unicode Consortium has finalized and released version 16.0 of the Unicode standard, the elaborate character set that ensures that our phones, tablets, PCs, and other devices can all communicate and interoperate with each other. The update adds 5,185 new characters to the standard, bringing the total up to a whopping 154,998.
Of those 5,185 characters, the ones that will get the most attention are the eight new emoji characters, including a shovel, a fingerprint, a leafless tree, a radish (formally classified as “root vegetable”), a harp, a purple splat that evokes the ’90s Nickelodeon logo, and a flag for the island of Sark. The standout, of course, is “face with bags under eyes,” whose long-suffering thousand-yard stare perfectly encapsulates the era it has been born into. Per usual, Emojipedia has sample images that give you some idea of what these will look like when they’re implemented by various operating systems, apps, and services.
We last got new emoji in 2023’s Unicode 15.1 update, though all of these designs were technically modifications of existing emoji rather than new characters—many emoji, most notably for skin and hair color variants, use a base emoji plus a modifier emoji, combined together with a “zero-width joiner” (ZWJ) character that makes them display as one character instead. The lime emoji in Unicode 15.1 was actually a lemon emoji combined with the color green; the phoenix was a regular bird joined to the fire emoji. This was likely because 15.1 was only intended as a minor update to 2022’s Unicode 15.0 standard.
Most of the Unicode 16.0 emoji, by contrast, are their own unique characters. The one exception is the Sark flag emoji; flag sequences are created by placing two “regional indicator letters” directly next to each other and don’t require a ZWJ character between them.
Incorporation into the Unicode standard is only the first step that new emoji and other characters take on their journey from someone’s mind to your phone or computer; software makers like Apple, Google, Microsoft, Samsung, and others need to design iterations that fit with their existing spin on the emoji characters, they need to release software updates that use the new characters, and people need to download and install them.
We’ve seen a few people share on social media that the Unicode 16.0 release includes a “greenwashing” emoji designed by Shepard Fairey, an artist best known for the 2008 Barack Obama “Hope” poster. This emoji, and an attempt to gin up controversy around it, is all an elaborate hoax: there’s a fake Unicode website announcing it, a fake lawsuit threat that purports to be from a real natural gas industry group, and a fake Cory Doctorow article about the entire “controversy” published in a fake version of Wired. These were all published to websites with convincing-looking but fake domains, all registered within a couple of weeks of each other in August 2024. The face-with-bags-under-eyes emoji feels like an appropriate response.
Apple plans to release the next versions of iOS, iPadOS, macOS, and watchOS to the general public on September 16, the company announced via its website following its iPhone-centric product event earlier today. We should also see updates for tvOS and the HomePod operating system on the same date.
The new releases bring a number of new features and refinements to Apple’s platforms: better texting with Android devices thanks to support for the RCS standard, iPhone Mirroring that allows you to interact with your iPhone via your Mac, more UI customization options for iPhones and iPads, and other improvements besides.
What won’t be included in these initial releases is any hint of Apple Intelligence, the batch of generative AI and machine learning features that Apple announced at its Worldwide Developers Conference in June. Apple is testing some of the Apple Intelligence features in betas of iOS 18.1, iPadOS 18.1, and macOS 15.1, updates that will be released later this fall. When Apple Intelligence does arrive, compatibility will be limited: it will require an iPhone 15 Pro or one of the just-announced iPhone 16 or 16 Pro models; an iPad Air or Pro with an M1, M2, or M4 chip; or an Apple Silicon Mac. Apple will also be withholding Apple Intelligence from devices in the EU, at least for now.
The new operating systems will run on most of the same hardware that is currently compatible with iOS 17, iPadOS 17, and macOS Sonoma, including the last few generations of Intel Macs from 2018, 2019, and 2020. But there are a handful of exceptions, like the 2018 MacBook Air and a handful of older iPads. Phones as old as 2018’s iPhone XR and XS will be able to install and run the iOS 18 update.
Apple has released multiple beta versions of each operating system since WWDC in June, and release candidate builds will likely go out to users and developers today. These will enable developers to get final versions of their apps ready for launch day. Users who want to move over to the new operating systems early can also do so—you can be relatively confident that most of the biggest bugs have been worked out over the summer betas. However, as always when installing major updates, you should ensure you have good backups of your data beforehand.
For the last couple years, Apple has reserved its most significant silicon updates for its iPhone Pro models, while the less expensive non-Pro iPhones have made do with year-old chips. This year, Apple is introducing new A18-series chips for both Pro and non-Pro iPhones, chips which it says are “designed for Apple Intelligence from the ground up.”
The Apple A18 (no Pro, no Bionic, just A18) will power the new iPhone 16 and 16 Plus—the iPhone 15 used an A16 Bionic, and jumping two chip generations in one year makes for more impressive-sounding performance numbers.
Like the last few generations of iPhone chip, the A18 includes a 6-core CPU with two high-performance processor cores and four high-efficiency cores. Apple says the CPU is 30 percent faster than the A16 chip in the iPhone 15. The A18 also includes a 5-core GPU that Apple says is 40 percent faster than the GPU in the iPhone 15—the A18 GPU also supports hardware-accelerated ray tracing, which was introduced in the A17 Pro.
Enlarge/ The A18 includes a six-core CPU with two high-performance cores and four high-efficiency cores.

A 16-core neural engine will accelerate Apple Intelligence’s AI and machine learning capabilities, and 17 percent higher memory bandwidth compared to the A16 rounds out its capabilities. The chip is built using a “second-generation 3 nm” manufacturing process, most likely from longtime Apple manufacturing partner TSMC.
Apple didn’t mention RAM specifically—it rarely does, for iPhones—but the A18 likely has at least 8GB of RAM to help it run Apple Intelligence models. The A16 in the iPhone 15 included 6GB of RAM.
Apple
The iPhone 16 Pro gets a new Pro chip; the A18 Pro’s upgrades over the A18 are mostly subtle, and it’s less of an upgrade over the iPhone 15 Pro and its A17 Pro chip.
Apple is still using a six-core CPU with two high-performance cores and four high-efficiency cores, but Apple says that “larger caches” and “next-generation ML accelerators” will boost its performance a bit beyond the cores in the regular A18. Apple says CPU performance should be around 15 percent faster than in the A17 Pro.
The GPU in the A18 Pro uses the same architecture as the A18, but it has six GPU cores instead of five, and it is 20 percent faster than the A17 Pro’s GPU. Apple said that hardware-accelerated ray tracing could be up to twice as fast as in the A17 Pro, but the regular A18 Pro should benefit from this improvement, too. The A18 Pro has the same 16-core Neural Engine as the A18, and also benefits from 17 percent more memory bandwidth.
Enlarge/ Better video and I/O capabilities help separate the A18 Pro from the regular A18.
Apple
Some things that make the A18 Pro “pro” are related to its I/O, and its media encoding and decoding hardware. The A18 Pro supports ProRes video encoding, has a new image signal processor that apparently isn’t in the A18, and also supports “faster USB 3 speeds” than the A17 Pro. For those using their iPhones to shoot professional-grade video, these are small but welcome improvements over the A18 that will help shoot better video, and make it easier to offload video to a computer when it’s time to edit.
