REC Silicon is preparing to fulfill its first shipment of polysilicon granules, which are used in the production of solar panels, at its factory in Moses Lake, Wash.

What to expect from Apple’s May 7 β€œLet loose” event

On May 7, Apple will host a product announcement event at 9 am ET. Labeled "Let loose," we expect it will focus on new iPads and iPad accessories.

We won't be liveblogging the stream, but you can expect some news coverage as it happens. Below, we'll go over our educated guesses about why Apple might be doing this.

Why hold an event now?

It's unusual for Apple to host an event shortly before WWDC. New products debut at that event all the time, so if it's just a faster chip and a nicer screen for the iPad Pro and iPad Air, why not wait until June?

Apple announces M4 with more CPU cores and AI focus, just months after M3

In a major shake-up of its chip roadmap, Apple has announced a new M4 processor for today’s iPad Pro refresh, barely six months after releasing the first MacBook Pros with the M3 and not even two months after updating the MacBook Air with the M3.

Apple says the M4 includes "up to" four high-performance CPU cores, six high-efficiency cores, and a 10-core GPU. Apple's high-level performance estimates say that the M4 has 50 percent faster CPU performance and four times as much graphics performance. Like the GPU in the M3, the M4 also supports hardware-accelerated ray-tracing to enable more advanced lighting effects in games and other apps. Due partly to its "second-generation" 3 nm manufacturing process, Apple says the M4 can match the performance of the M2 while using just half the power.

As with so much else in the tech industry right now, the M4 also has an AI focus; Apple says it's beefing up the 16-core Neural Engine (Apple’s equivalent of the Neural Processing Unit that companies like Qualcomm, Intel, AMD, and Microsoft have been pushing lately). Apple says the M4 runs up to 38 trillion operations per second (TOPS), considerably ahead of Intel's Meteor Lake platform, though a bit short of the 45 TOPS that Qualcomm is promising with the Snapdragon X Elite and Plus series. The M3's Neural Engine is only capable of 18 TOPS, so that's a major step up for Apple's hardware.

M4 iPad Pro CPU cores and RAM amount are tied to storage capacity

When Apple announced the Apple M4 chip during its iPad Pro event yesterday, it mentioned that the chip came with "up to" four high-performance CPU cores.

Those short, easily missable words always mean that there's a lower-end version of the chip coming thatΒ doesn'tΒ include that many CPU cores, and the tech specs page for the new iPad Pro has the full details: iPad Pros with 256GB or 512GB of storage use a version of the M4 with three high-performance CPU cores and six smaller efficiency cores. Only the models with 1TB and 2TB of storage have an M4 with all four high-performance CPU cores enabled.

The 256GB and 512GB models also ship with 8GB of RAM, where the 1TB and 2TB models come with 16GB of memory installed. Though these changes are clearly spelled out on the Tech Specs page, the actual configuration page for the iPad Pros in Apple's online store doesn't give any indication that upgrading storage also upgrades your CPU and RAM.

Fedora Asahi Remix 40 is another big step forward for Linux on Apple Silicon Macs

Asahi Linux, the project that aims to bring desktop Linux to Apple hardware with Apple siliconβ€”the M series of chipsβ€”is out with Fedora Asahi Remix 40. More hardware features of Apple devices are supported, the Fedora Linux 40-based distro ships with KDE's new Plasma 6 desktop, and untold numbers of bugs are squashed, to be replaced with reams more.

Fedora Asahi Remix is a "fully integrated distro," according to the Asahi team, and you can "expect a solid and high-quality experience without any unwanted surprises." It supports all the M1 and M2 devices in the MacBook, Mac Mini, Mac Studio, and iMac lines. It's OpenGL 4.6 and OpenGL ES 3.2 certified, and comes with "the best Linux laptop audio you've ever heard."

So, should you install it on your Mac? Keep scrolling down Asahi's release page and check the "Device support" section. Still missing from most M-series Apple devices are support for Thunderbolt and USB4, built-in microphones, and Touch ID, as well as USB-C display support. Speakers are not supported on the iMac. And HDMI audio is in rough shape, being able to "break audio on the system completely."

M2 iPad Air review: The everything iPad

The iPad Air has been a lot of things in the last decade-plus. In 2013 and 2014, the first iPad Airs were just The iPad, and the β€œAir” label simply denoted how much lighter and more streamlined they were than the initial 2010 iPad and 2011’s long-lived iPad 2. After that, the iPad Air 2 survived for years as an entry-level model, as Apple focused on introducing and building out the iPad Pro.

The Air disappeared for a while after that, but it returned in 2019 as an in-betweener model to bridge the gap between the $329 iPad (no longer called β€œAir,” despite reusing the first-gen Air design) and more-expensive and increasingly powerful iPad Pros. It definitely made sense to have a hardware offering to span the gap between the basic no-frills iPad and the iPad Pro, but pricing and specs could make things complicated. The main issue for the last couple of years has been the base Air's 64GB of storageβ€”scanty enough that memory swapping doesn't even work on itβ€” and the fact that stepping up to 256GB brought the Air too close to the price of the 11-inch iPad Pro.

Which brings us to the 2024 M2 iPad Air, now available in 11-inch and 13-inch models for $599 and $799, respectively. Apple solved the overlap problem this year partly by bumping the Air's base storage to a more usable 128GB and partly by making the 11-inch iPad Pro so much more expensive that it almost entirely eliminates any pricing overlap (only the 1TB 11-inch Air, at $1,099, is more expensive than the cheapest 11-inch iPad Pro).
