Over at CES 2020, Intel gave a brief Thunderbolt 4 demonstration. Support for the new protocol will be provided by the future 10nm+ Tiger Lake processors, but it appears Thunderbolt 4 will not provide a performance upgrade. The chip giant said Thunderbolt 4 will be four times faster than today's USB, which puts it at around 40Gbps, which is the same as the maximum bandwidth of Thunderbolt 3.
Intel hinted at some changes but said more details would follow later.
"It standardizes PC platform requirements and adds the latest Thunderbolt innovations," Intel spokeswoman Sarah Kane said in a statement, adding that Intel plans to share more about Thunderbolt 4 later.
Thunderbolt 4 will be backwards compatible with Thunderbolt 3.
