Rather, those features will require the Apple-designed M1 chip (or presumably its upcoming successors) found in new Macs the company has introduced since late last year.
The clarification appears in the fine print on Apple's "macOS Monterey Preview" page. Meanwhile, some listed features are associated with a footnote that reads "Available on Mac computers with the M1 chip."
Some of these (for example, Live Text) are likely explained by the fact that the chipsets in Intel Macs lack a viable equivalent to the 16-core Neural Engine NPU present on Apple's M1. This component of the M1 is focused on machine-learning tasks and is drastically faster at those tasks than anything in the Intel Macs.
Aside from the improved picture quality of the 24-inch iMac's M1 ISP-driven FaceTime camera, this is the first time we've come across an example of the M1 Macs offering something more than improved performance and power efficiency.
This revelation comes at a time when only a portion of the Mac lineup has yet been updated with Apple Silicon. All of the company's high-end laptops and desktops still have Intel chips, such as the 16-inch MacBook Pro or 27-inch iMac. That is expected to change this year with the introduction of a new M1 successor with a 10-core CPU and either 16- or 32-core GPU.
