At the WWDC conference in June, Apple announced the Mac computer with its own processorAnd now there are developers, pushing developers to switch to arm Macs. With this strategy, Apple will no longer rely on AMD, Intel or NVIDIA for CPU or GPU in the future, and these three companies will collectively leave the arm version of MAC.

There's only one technology that ca n' t get rid of Intel, Thunderbolt,. Last night Intel released the latest Thunderbolt 4 standards, the rate is still 40 Gbps, but in video output, PCIe transmission and other aspects of the speed doubled, while compatible with future USB4 standards.

Intel also launched the new thunderbolt 4 controller 8000 Series, including jhl8540 and jhl8340 host controllers for computer manufacturers and jhl8440 device controllers for accessory manufacturers, which will be available at the end of this year.

Apple has made a statement,They will continue to use the thunderbolt 4 interface.

Thunderbolt interface technology can not be said to be Intel exclusive, although it originated from Intel light Peak technology, but made the standard is to cooperate with apple, and apple initially has an exclusive period, Thunderbolt the ecological growth of apple also thanks to apple.

Apple should not want to get rid of thunderbolt's dependence on Intel, but they don't have the control of this technology, and they probably can't do their own master control. They deny that apple can't lift the table.


As long as apple has the ability, it is not difficult to lift the table where other manufacturers eat together. This is the case with the CPU and GPU of the arm Mac, The company has made it clear in its official documents that it will use its own CPU/GPU,AMD、Intel and NVIDIA collectively, but not yet Intel version of its Mac computer, all of which have a chance.


There is no doubt that apple is ambitious on the ARM version of the Mac, with Mac OS and iOS software ecology in its hands and hardware, and even PCIe universal standards like this, apple will design a IOMMU unit control device in its own chip on the grounds that it can prevent eavesdropping and be safer.
