Þar semThunderbolt tengi var opinberlega tilkynnt árið 2011, flutningshraði þess hefur verið aukið úr upprunalegu 10Gb / s í þriðju kynslóð / 4. kynslóð 40Gb / s, ogÞrumufleygur 3forskrift siðareglna hefur einnig orðið grundvöllur USB4 forskriftarinnar. Þrumufleygur 4var tilkynnt klCESárið 2020, og lokaútgáfan af forskriftinni var gefin út í þessum mánuði.
Þrumufleygur 4er í fullu samræmi viðUSB4forskrift.
Þó að gagnaflutningshraði sé sá sami og fyrri kynslóð, hefur lágmarks bandbreiddarkrafa fyrir PCIe hlekkinn verið aukin úr 16Gb / s í 32Gb / s. Það styður einnig tvöfalda rás 4K skjá eða einrás 8K skjá og Intel VT-d DMA vörn til að forðast líkamlegar DMA árásir.
Intel hefur einnig gert nokkrar erfiðar kröfur fyrir tölvur með Þrumufleygur 4tækni, svo sem að hafa að minnsta kosti einaÞrumufleygur 4interface, and the interface can be used to charge the computer. When interacting with the computer’s mouse or keyboard, the Þrumufleygur 4docking station also supports wake-up from sleep. According to data provided by Intel, the cable that currently supports Þrumufleygur 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 tilkynnti í þessum mánuði að það styðurÞrumufleygur 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 Thunderbolt tengi 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 Þrumufleygur 3vottun.
