Kwa kuwaMuunganisho wa radi ilitangazwa rasmi mnamo 2011, kiwango cha usafirishaji kimeongezwa kutoka 10Gb / s asili hadi kizazi cha tatu / kizazi cha 4 40Gb / s, na3 radivipimo vya itifaki pia imekuwa msingi wa vipimo vya USB4. Radi 4 ilitangazwa saaCESmnamo 2020, na toleo la mwisho la vipimo ilitolewa mwezi huu.
Radi 4 inakubaliana kabisa naUSB4vipimo.
Ingawa kiwango cha uhamishaji wa data ni sawa na kizazi kilichopita, hitaji la chini la upelekaji wa kiunga cha PCIe limeongezwa kutoka 16Gb / s hadi 32Gb / s. Inasaidia pia onyesho la 4K la njia mbili au onyesho la 8K ya kituo kimoja, na ulinzi wa Intel VT-d DMA ili kuepuka shambulio la DMA la mwili.
Intel pia imefanya mahitaji magumu kwa PC na teknolojia ya Thunderbolt 4, kama vile kuwa na angalau moja4 radiinterface, and the interface can be used to charge the computer. When interacting with the computer’s mouse or keyboard, the 4 radidocking station also supports wake-up from sleep. According to data provided by Intel, the cable that currently supports 4 radican 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 ilitangaza mwezi huu kwamba inasaidia4 radi8000 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 Muunganisho wa radi 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 3 radivyeti.
