Cal é o porto Thunderbolt 4do novo MacBook?

 

Dende oInterface Thunderbolt anunciouse oficialmente en 2011, a súa velocidade de transmisión aumentou dos 10Gb / s orixinais á terceira xeración / 40Gb / s da 4a xeración eThunderbolt 3a especificación de protocolo tamén se converteu na base da especificación USB4. Thunderbolt 4anunciouse enCESen 2020, e a versión final da especificación foi lanzada este mes.

 

Thunderbolt 4é totalmente compatible coUSB4especificación. 

Aínda que a taxa de transferencia de datos é a mesma que a xeración anterior, o requisito de ancho de banda mínimo para a ligazón PCIe aumentou de 16Gb / s a ​​32Gb / s. Tamén admite a pantalla 4K de dobre canle ou a pantalla 8K de canle único e a protección DMA Intel VT-d para evitar ataques físicos de DMA.

Intel tamén fixo algúns requirimentos difíciles para ordenadores con tecnoloxía Thunderbolt 4, como ter polo menos unThunderbolt 4interface, and the interface can be used to charge the computer. When interacting with the computer’s mouse or keyboard, the Thunderbolt 4docking station also supports wake-up from sleep. According to data provided by Intel, the cable that currently supports Thunderbolt 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.

Intel anunciou este mes que admiteThunderbolt 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 Interface 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 Thunderbolt 3certificado.
