Apple may be struggling with its next Mac chips — here’s why that matters

Apple’s chip manufacturer is “straining to meet demand” for the chips that will power future Macs, according to a report from EE Times. If these difficulties continue, it could have worrying implications for Apple with just months to go before the 3-nanometer M3 chip is set to debut.

TSMC is currently manufacturing Apple’s 3nm chips (which TSMC calls N3), and the EE Times report notes that TSMC’s “tool and yield struggles have impeded the ramp to volume production.” Aside from Samsung, TSMC is the only company that has the ability to make these chips, so any kind of delay could be of grave concern for Apple execs.

It could also have a knock-on effect for Mac fans. If TSMC cannot produce the number of chips Apple requires for its future Macs, Apple might have to delay the roll-out of the next line of iMacs and MacBooks, all of which are expected to launch with the 3nm M3 chip in late 2023 or early 2024.

As well as the M3, Apple’s iPhone 15 chip (the A17 Bionic) is expected to be made using a 3nm process. The next iPhones are due to launch in September 2023, so Apple will be hoping TSMC can turn things around in time for its most important product to be unveiled.

The EE Times report follows a statement from TSMC CEO C.C. Wei, who last week explained that although the company was the first in the industry to achieve “high-volume production with good yield” for 3nm chips, its customers’ demands “exceed our ability to supply.”

A temporary blip?

However, not every analyst EE Times spoke to is feeling so glum. According to Arete Research analyst Brett Simpson, “At present, we believe N3 yields at TSMC for A17 and M3 processors are at around 55%.” While that might not sound too encouraging, Simpson explains that it’s a “healthy level at this stage in N3 development.” Simpson also expects TSMC to boost its chip yields “by around 5+ points each quarter.”

It seems that TSMC believes its current 3nm struggles will be a temporary blip since it is already planning to move to a 2nm process in 2025. Wei stated that TSMC is “observing a high level of customer interest and engagement” for its 2nm process, and Apple will undoubtedly be near the front of the queue.

That’s because Apple is known to be one of TSMC’s primary customers, and the Cupertino giant has reportedly bought TSMC’s entire supply of 3nm chips. That means it’s even more important for Apple fans that the manufacturer’s current difficulties do not end up delaying Apple’s next batch of Macs. We’ve got our fingers crossed.

Why Apple’s M3 Ultra could be an absolute monster

There's one M3 chip left to complete the rollout of Apple's latest line of Mac chips -- the M3 Ultra. It'll likely get announced at Apple's Worldwide Developers Conference (WWDC), but some new rumors are pointing to a very different chip than the M2 Ultra or M1 Ultra.

A new post on X from Apple commentator and YouTuber Vadim Yuryev indicates that the M3 Ultra will be designed as a completely standalone chip, rather than two M3 Max chips stitched together.

The case for buying the M2 MacBook Air over the M3 model
The screen of the MacBook Air M2.

Apple's MacBook Air M2 recently stood at the top of our list of best laptops, and for good reason. It's incredibly well-built, exuding an elegance that few laptops can match. It's also plenty fast for productivity users, and its GPU is optimized for creators. Its keyboard, touchpad, and display are all top-notch.

Enter the MacBook Air M3, which (hint) took over the MacBook Air's place on that list. The upgraded chipset offers even faster performance, particularly in GPU-intensive apps, and the M3 model supports an additional external display (with the display closed). It's $100 more, but is that uptick in price justified? Let's dig in.

Why you should buy a MacBook Pro instead of a MacBook Air

There are plenty of reasons to buy a MacBook Air instead of a MacBook Pro. If you want a MacBook on a budget, you don't necessarily need the goodies that come with upgrading to the MacBook Pro.

That being said, I'm going to argue for spending a little more. In my experience, the MacBook Pro offers several distinct advantages that help justify a higher price, especially with the introduction of the more affordable MacBook Pro 14 with the base M3. If you can stretch your budget a bit, here's why I think you should buy a MacBook Pro instead of a MacBook Air.
