Apple has launched a new MacBook Air, powered by the M4 chip that debuted last year on the iPad Pro and gradually made its way to the MacBook Pro and iPad Air. The new M4 chip is claimed to offer twice as fast performance as the M1-powered MacBook Air, but it can deliver up to 23x faster performance when compared with an Intel-based MacBook Air. On the other hand, the new Mac Studio comes in M4 and a new M3 Ultra variants, both offering performance suitable for intense workloads.
