KusukelaIsixhumi esibonakalayo se-Thunderbolt yamenyezelwa ngokusemthethweni ngo-2011, izinga lokudluliswa kwalo lenyukile lisuka ku-10Gb / s lasekuqaleni laya esizukulwaneni sesithathu / isizukulwane sesine i-40Gb / s, kanyeUkuduma Kwezulu 3Ukucaciswa kweprotocol nakho kube yisisekelo sokucaciswa kwe-I-USB4. I-Ukuduma Kwezulu 4yamenyezelwa eI-CESngo-2020, futhi uhlobo lokugcina lwesicaciso lukhishwe kule nyanga.
I-Ukuduma Kwezulu 4ihambisana ngokuphelele neI-USB4incazelo.
Yize inani lokudluliswa kwedatha lilingana nesizukulwane esedlule, imfuneko encane yomkhawulokudonsa wesixhumanisi se-PCIe inyusiwe isuka ku-16Gb / s yaya ku-32Gb / s. Iphinde isekele isibonisi se-4K esinezindlela ezimbili noma isiteshi esisodwa se-8K, kanye nokuvikelwa kwe-Intel VT-d DMA ukugwema ukuhlaselwa ngokomzimba kwe-DMA.
I-Intel iphinde yenze ezinye izidingo ezinzima zama-PC ngobuchwepheshe beThunderbolt 4, njengokungenani okungenani eyodwaUkuduma Kwezulu 4interface, and the interface can be used to charge the computer. When interacting with the computer’s mouse or keyboard, the Ukuduma Kwezulu 4docking station also supports wake-up from sleep. According to data provided by Intel, the cable that currently supports Ukuduma Kwezulu 4can be as long as 2m, and active cables of 5 to 50m will be introduced in the future. The interface power required by related accessories is still maintained at 15W. As one of the designers of Thunderbolt, Intel’s new mobile processors Tiger Lake will also be the first to support Thunderbolt 4.
MinaI-ntel 8000 Series Controller / Intel
I-Intel imemezele kule nyanga ukuthi iyasekelaUkuduma Kwezulu 48000 series controllers, including JHL8540 and JHL8340 host controllers for computer manufacturers, and JHL8440 device controllers for accessory manufacturers. Apple, another designer of Thunderbolt, is already preparing to abandon Intel's chips on the Mac and switch to the ARM platform, but Apple claims that due to the speed and flexibility of the interface, Mac computers will continue to support the Isixhumi esibonakalayo se-Thunderbolt in the future. In order to increase the market share of Thunderbolt, Intel also exempted OEMs and chip manufacturers from patent fees on this standard in 2018. The ASRock X570 launched this year has also become the first AMD motherboard to pass Ukuduma Kwezulu 3isitifiketi.
