Apple introduced new MacBook Pro laptops with updated processors on Wednesday, likely the company’s last major hardware announcement of the year.

The new devices are equipped with Apple’s latest chip, the M4. Some models have access to more powerful versions, called the M4 Pro and M4 Max. Apple says the new chips are 1.8 times faster than the M1, which powered Apple’s 2021 MacBook Pro.

Apple has also made a significant change across its Mac range to prepare the computers for future artificial intelligence features.

Apple said the new models, like all devices released this year, are designed for Apple Intelligence, the company’s AI system that can generate text, images and emojis.

Additionally, all new MacBook Pro models come with at least 16 GB of RAM. Until now, low-end Macs often came with 8 GB of RAM as standard. The more memory a computer has, the better it is able to handle larger and more advanced AI models.

Apple’s MacBook Air laptops and iMac desktops are also getting an update to start with at least 16GB of RAM at the same $999 starting price as before. The M4 also has improved AI capabilities. Doubling the RAM on its laptops represents the most significant change Apple has made to its line of computers to better support Apple Intelligence.

The 2021 MacBook Pro redesign was praised for a thicker design that allowed the computer to have several traditional ports, such as an HDMI port for connecting the computer to TV screens and projectors. The re-release was part of a wave of Mac launches in 2021 that revived the product line, in addition to Apple’s decision to transition from Intel chips to its own M series.

Apple’s Mac range is crucial to the company, even if it brings in less total revenue than the iPhone or its wearables business, which also includes the Apple Watch and AirPods. For example, all apps made for iPhones were written on a Mac.

In the quarter ending in June, Apple reported $7 billion in Mac sales, up about 2% from the same period a year earlier. Apple reports results for the latest quarter on Thursday.

The 14-inch Mac starts at $1,599 and the 16-inch model starts at $2,499. The 14-inch model with the more powerful M4 Pro chip starts at $1,999. Apple says some models of the M4 MacBook Pro can have up to 24 hours of battery life. The new MacBook Pro models also received an improved 12-megapixel camera for video conferencing.

The new laptops will hit store shelves on November 8.
