Skip to ContentXlr8yourmac.com provides clarification on the hot-topic of DDR in the new PowerMacs:
I'm getting lots of mails on this but as you can clearly see from the Apple PowerMac G4 specs page - they note the system bus bandwidth at 1.3GB/sec - clearly indicating that is *not* a DDR system/CPU (frontside) bus. Just like the Xserve, the new G4s use a single data rate system/cpu bus and a DDR memory bus.
Railheaddesign also provides a detailed explanation of the DDR implementation on the new PowerMacs.
MagSafe Battery Pack support, the ability to merge two existing Apple Card accounts, HomePod timer management in the Home app, and more.
New features for FaceTime calls, tools to reduce distractions, a new notifications experience, added privacy features, complete redesigns for Safari, Weather, and Maps, and more.
Updates for Safari, FaceTime, and many other apps, Universal Control to let a single mouse or trackpad control multiple devices, new Shortcuts app, machine-learning Live Text detection and Visual Lookup, and more.
Redesigned with flat edges, Apple silicon, more ports, improved display, no Touch Bar, and the return of MagSafe charging.
Rumored design changes include shorter stems like current AirPods Pro, but without advanced features like active noise cancellation.
