Presents 4, Thunderbolt, Thunderbolt 3 but faster he did not

For starters, if someone suddenly does not know what is Thunderbolt and why it should not be confused with USB-C, I advise you to read this our article. Given her age of two years, certain things have become clearer, but most of the information there is relevant.

We now turn to Thunderbolt 4. For the first time Intel talked about this interface early in the year, and then we learned that the data transfer speed will not change, then there will be a maximum of 40 Gbit/s. Actually, the way it is, and this news could be complete. But of course we do it will not.

So, the new interface was not faster than the old one. What exactly are the differences and do they exist? They are, but not to say very important. For example, to Thunderbolt 4 will be released certified universal cables 2 meters long, which was not for Thunderbolt 3. In addition, Intel is working on some optical cables with a length of from 5 to 50 meters, but the details about them no, it is not clear when they will be released, and I can only imagine how much they might cost.

The second difference is that the new controller allows you to create accessories with four Thunderbolt ports 4 against two in the case of Thunderbolt 3. Also the new interface allows you to connect two monitors or one 4K 8K. Doubled to 32 GB/s — increased the speed of data transfer when connecting the PCIe Protocol.

One of the extremely interesting innovation is the requirement from Intel to implement a protection against DMA attacks via Intel VT-d. The problem is that it is an Intel technology and implemented its support in processors and chipsets of Intel. This means that PCs with AMD processors or the Apple Silicon this condition will not be executed. A number of thematic resources has asked for comments by Intel and AMD, but until they are received. Guess there must be some alternative, otherwise the same new Mac with the Apple Thunderbolt to support 4 simply can not.

What is the result? Up Thunderbolt 4 deprived of the benefits that had previous iterations of the interface speed. USB 4 also assumes a speed of 40 GB/s, so not very clear the reasons why Intel did not want or could not do Thunderbolt 4 faster. While the fate of this interface seems vague, but to do definitive conclusions early.

Updated: Apple officially commented on the situation, saying that her ARM Mac will support the new interface. It is unclear how it fits with requirements Intel, but they will.

Please wait…
