Apple announces M3 Ultraβ€”and says not every generation will see an β€œUltra” chip

Apple’s first Mac Studio refresh in nearly two years is a welcome update, injecting fresh life into two computers that were still getting by with M2 chips. But the company took a bit of a strange approach to the update, giving an M4-series Max chip to the lower-end Studio but an M3 Ultra chip to the high-end model.

These processors are both performance upgrades from the M2 Max and M2 Ultra, and the M3 Ultra is so huge that it should have no trouble outrunning the M4 Max despite its slightly older CPU and GPU architecture. But it’s still a departure from past practice, where Apple would keep the Studio’s chip generation in lockstep.

CPU P/E-cores GPU cores RAM options Memory bandwidth
Apple M3 Ultra (low) 20/8 60 96/256GB 819.2GB/s
Apple M3 Ultra (high) 24/8 80 128GB/256GB/512GB 819.2GB/s
Apple M2 Ultra (high) 16/8 76 Up to 192GB 819.2GB/s
Apple M1 Ultra (high) 16/4 32 Up to 128GB 819.2GB/s

When asked why the high-end Mac Studio was getting an M3 Ultra chip instead of an M4 Ultra, Apple told us that not every chip generation will get an β€œUltra” tier. This is, as far as I can recall, the first time that Apple has said anything like this in public.

Apple intros new Mac Studio models with M4 Max and… M3 Ultra?

Apple announced its first Mac Studio updates in nearly two years today, a few months after bringing the M4 and M4 Pro chips to the Mac mini.

As before, Apple offers a lower-end and a higher-end configuration of the Mac Studio. The lower-end model is pretty much what you expect: It gives you the same M4 Max processor Apple introduced in the high-end MacBook Pro last year. It has up to 16 CPU cores (10 P-cores, 4 E-cores), up to 40 GPU cores, and a 16-core Neural Engine.

The $1,999 base model comes with 14 CPU cores (10 P-cores, 4 E-cores), 32 GPU cores, 36GB of RAM, and 512GB of storage. That model's RAM can't be upgraded until you step up to the fully-enabled M4 Max, which also gets you 48GB of RAM for $300. From there, the desktop can be upgraded with either 64GB or 128GB of RAM, same as the MacBook Pro.

MacBook Air gets the M4, a new blue color, up to 32GB of RAM, and a $100 price cut

As expected, Apple has officially refreshed its MacBook Air lineup with its M4 chip, the same silicon we've already seen in products like the MacBook Pro, the iMac, and the Mac mini. And in most ways, it's a straightforward update, with no major changes to the laptop's physical design, screen specs, keyboard, or ports.

The most important update is the price. The 13-inch M4 MacBook Air will start at $999, a $100 price cut compared to the M3 Air and the same price that Apple set for the M2 Air last year when the M3 models came out. The 15-inch model will also get a $100 cut, from $1,299 to $1,199. These baseline configurations still come with 16GB of RAM and 256GB of storage, plus the 8-core version of the M4's GPU.

The M2 version will continue to be sold as a budget model in some countries, but the US isn't one of them. Apple will also continue to sell a cheaper version of the M1 MacBook Air through Walmart, which it has been doing since March 2024.

Apple’s M4 MacBook Air refresh may be imminent, with iPads likely to follow

Apple's slow trickle of early 2025 product announcements is apparently set to continue this week, following the introduction of the iPhone 16e a couple of weeks ago. According to Bloomberg's Mark Gurman, the company plans to refresh its 13- and 15-inch MacBook Air laptops "as early as this coming week," adding the M4 processor that Apple put in the iMac, Mac mini, and MacBook Pro lineups last fall.

An M4 refresh for the MacBook Air was always likely, but Apple has kept us guessing about the timing. Usually, the MacBook Airs are among the first devices to get new M-series processors from Apple, but Apple surprised us by bringing the M4 to the iPad Pro just a few months after introducing the M3. In mid-December, concrete references to the M4 MacBook Air appeared in the macOS 15.2 update, suggesting that the laptops were in testing, even if they weren't ready for a public launch yet.

The laptops are unlikely to look too different from the current M2 or M3 MacBook Airs, which got an "update" of sorts last fall when Apple discontinued the versions with 8GB of RAM in favor of 16GB versions that kept the same prices.

Errant reference in macOS 15.2 seems to confirm M4 MacBook Airs for 2025

The macOS 15.2 update that was released earlier today came with a handful of new features, plus something unexpected: an apparently accidental reference to the upcoming M4 MacBook Airs. MacRumors reports that the "Mac16,12" and "Mac16,13" model identifiers reference 13- and 15-inch models of the M4 Air and that both are coming in 2025.

That a MacBook Air refresh is planned for next year isn't much of a surprise at this pointβ€”in reporting that pretty much nailed the details of the first M4 Macs, Bloomberg's Mark Gurman has said that the Air, the Mac Studio, and the Mac Pro are all slated for updates throughout 2025.

But a reference in the current release of macOS could point to a launch sooner rather than later; the M4 Mac mini was referenced in a macOS update in mid-September around a month and a half before it was released. The M3 Airs came out in March this year, but Apple has been known to put out new Macs as early as January in recent years.

Join us today for Ars Live: How Asahi Linux ports open software to Apple’s hardware

One of the key differences between Apple's Macs and the iPhone and iPad is that the Mac can still boot and run non-Apple operating systems. This is a feature that Apple specifically built for the Mac, one of many features meant to ease the transition from Intel's chips to Apple's own silicon.

The problem, at least at first, was that alternate operating systems like Windows and Linux didn't work natively with Apple's hardware, not least because of missing drivers for basic things like USB ports, GPUs, and power management. Enter the Asahi Linux project, a community-driven effort to make open-source software run on Apple's hardware.

In just a few years, the team has taken Linux on Apple Silicon from "basically bootable" to "plays native Windows games and sounds great doing it." And the team's ultimate goal is to contribute enough code upstream that you no longer need a Linux distribution just for Apple Silicon Macs.
