Apple M1 MacBook Can’t Get rid of Intel Chips
Even though the processor doesn’t use Intel anymore, Apple’s new MacBook Pro still hasn’t completely gotten rid of the chips provided by the former, such as Thunderbolt 4 master control. Thunderbolt 4 has the same maximum 40Gbps peak bandwidth as Thunderbolt 3 and can be connected to dual 4Kor single 8K displays.
The just-released MacBook Pro has three full-featured Thunderbolt 4 interfaces on the outside, and they all have to work smoothly with the help of Intel’s 8000 series Thunderbolt 4 master control to work. So, Apple wants to cut Intel completely in the future unless it customizes its own set of proprietary high-speed interface transmission standards.
Since Apple is a major member of the USB-IF Association, the Thunderbolt 4 for MacBook Pro also has the world’s first USB-C v2.1 interface standard, supporting USB PD 3.1 fast charging, which means a theoretical maximum of 48V/5A (240W). For security reasons, Apple has limited it to 28V/5A (140W), but unfortunately, there is no matching EPR USB-C cable on the market, so if you want to achieve 140W charging power, you can only do so with MagSafe 3 magnetic fast charging, which does not rule out the possibility of unlocking it in the future.
