The first one will be released this year
Yesterday’s announcement of the Thunderbolt 4 interface caused a lot of questions. For example, it is unclear why Thunderbolt 4 is not faster than Thunderbolt 3. In addition, Intel’s requirement to implement protection against DMA attacks using Intel VT-d technology hinted that Thunderbolt 4 could only be implemented on PCs with Intel processors.
No, Thunderbolt will not disappear from Apple computers. The company has confirmed that it will use Thunderbolt 4 in upcoming PCs without an Intel CPU
Of course, the upcoming Apple Macs on the company’s own processors immediately come to mind. However, today it became known that everything will be in order with them. Apple told the source that it will continue to use Thunderbolt, including in future PCs with Apple Silicon processors. True, the wording of Apple itself does not indicate which particular Thunderbolt standard will be used, but since the company answered a very specific question from journalists, we can safely talk about Thunderbolt 4.
The question with AMD processors remains open, but, apparently, in this case, the problem is also somehow solved.
