The first computers and accessories with Thunderbolt 4 ports are
expected to be available later this year, Intel said on Wednesday even
as Lenovo confirmed that it is working with the chipmaker to introduce
such devices.
Thunderbolt 4 is Intel's next generation universal cable connectivity solution which succeeds four-year-old Thunderbolt 3.
For
the first time, Thunderbolt 4 will offer docks with up to four
Thunderbolt ports and universal cables up to two meters in length, Intel
said, adding that its upcoming mobile PC processors, code-named "Tiger
Lake," will be the first to integrate Thunderbolt 4.
"The new
capabilities and minimum requirements of Thunderbolt 4 will provide
great experiences and increased productivity that our IT customers and
end users require," Jerry Paradise, Vice President, Commercial
Portfolio, Lenovo PC & Smart Devices, said in a statement.
"Lenovo
is excited to work with Intel to expand our support of Thunderbolt with
the introduction of Thunderbolt 4 PCs and the expanding portfolio of
Thunderbolt accessories."
In terms of speed of data transfer, however, Thunderbolt 4 will hardly score over what yet-to-be released USB4 promises.
Thunderbolt 4 will transfer data at 40 Gbps, the same speed that Thunderbolt 3 offers.
The
USB Promoter Group last year said that USB4 which is also expected to
debut in products later this year, would incorporate Thunderbolt 3
technology.
Intel also announced the Thunderbolt 4 controller
8000 series, compatible with the hundreds of millions of Thunderbolt 3
PCs and accessories already available.
The chipmaker said it
expects to deliver the new Thunderbolt 4 controller 8000 series later
this year. They include JHL8540 and JHL8340 host controllers for
computer makers; and JHL8440 device controller for accessory makers.
"Thunderbolt
provides consumers with a leading connectivity standard across a range
of devices, helping to advance computing experiences and delivering on
the promise of USB-C with simplicity, performance and reliability," said
Jason Ziller, Intel General Manager of the Client Connectivity
Division.
"The arrival of Thunderbolt 4 underscores how Intel is
advancing the PC ecosystem toward truly universal connectivity
solutions."
Thunderbolt 4 is the most comprehensive Thunderbolt
specification yet with compliance across the broadest set of
industry-standard specifications -- including USB4, DisplayPort and PCI
Express (PCIe) -- and is fully compatible with prior generations of
Thunderbolt and USB products, Intel said.
Thunderbolt 4 certification requirements include support for two 4K displays or one 8K display.
