What’s New:Intel revealed new details about Thunderbolt™ 4, the next generation of its
universal cable connectivity solution, delivering increased minimum performance
requirements,expanded capabilities and USB4 specification compliance. For the first time,
Thunderbolt 4 will offer
docks with up to four Thunderbolt ports and universal cables up to 2 meters in length.
Intel’supcoming mobile PC processors, code-named “Tiger Lake,” will be the first to
integrate Thunderbolt
Intel also announced the Thunderbolt 4 controller 8000 series, compatible with the
hundreds of
millions of Thunderbolt 3 PCs and accessories already available. Thunderbolt 4 developer
kits and
certification testing are now available.
“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. The arrival of Thunderbolt 4 underscores how Intel
is advancing the PC ecosystem toward truly universal connectivity solutions.” –Jason Ziller,
Intel general manager of the Client Connectivity Division
Why It Matters: Thunderbolt products deliver a consistent, industry-leading set of
capabilities forconnecting computers to data, video and power with the simplicity of just
one USB Type-C port.Connect to powerful Thunderbolt docks, displays, fast storage or any
USB accessory for a clutter-freeworkspace. To ensure a consistent best-in-class1 experience and ease of use across a wide range ofproduct types and manufacturers, Intel
works closely with its ecosystem of computer, accessory andcable partners to employ
mandatory certification for all Thunderbolt products.
“We expect Thunderbolt 4 products to be an inflection point for accessory makers who depend onPCs and Macs to offer an industry-leading set of product capabilities for a
consistent userexperience,” said Ben Thacker, vice president and general manager at Kensington. “Theadvancements in Thunderbolt 4 will help Kensington redefine the modern workspace of the future.”
“The new capabilities and minimum requirements of Thunderbolt 4 will provide great experiencesand increased productivity that our IT customers and end users require,” said Jerry Paradise, vicepresident,Commercial Portfolio, Lenovo PC & Smart Devices. “Lenovo is excited to work with Intel toexpand our support of Thunderbolt with the introduction of Thunderbolt 4 PCs and the expanding portfolio of Thunderbolt accessories.”
What It Delivers: Thunderbolt 4 builds on the innovation of Thunderbolt 3 for a truly universal cable
connectivity experience. Thunderbolt 4 always delivers 40 Gb/s speeds and data, video and powerover a single connection. It is the most comprehensive Thunderbolt specification yet with compliance across the broadest set of industry-standard specifications – including USB4, DisplayPort and PCIExpress (PCIe) – and is fully compatible with prior generations of Thunderbolt and USB products.Thunderbolt 4 certification requirements include:
• Double the minimum video and data requirements of Thunderbolt 3.
o Video: Support for two 4K displays or one 8K display.
o Data: PCIe at 32 Gbps for storage speeds up to 3,000 MB/s.
• Support for docks with up to four Thunderbolt 4 ports.
• PC charging on at least one computer port2.
• Wake your computer from sleep by touching the keyboard or mouse when connected to aThunderbolt dock.
• Required Intel VT-d based direct memory access (DMA) protection that helps prevent physical
DMA attacks. Read more in the Thunderbolt Security Brief.
When It Is Available: Later this year, Intel expects to deliver the new Thunderbolt 4 controller 8000
series, including:
- JHL8540 and JHL8340 host controllers for computer makers
- JHL8440 device controller for accessory makers
The first computers and accessories with Thunderbolt 4 ports are also expected to be available laterthis year, including laptops based on Intel’s innovation program code-named “Project Athena.”
The Small Print:
Intel technologies may require enabled hardware, software or service activation. Your costs and results may vary.
Performance results are based on testing as of dates shown in configuration and may not reflect all publicly available security updates. See
configuration disclosure for details. No product or component can be absolutely secure.
Software and workloads used in performance tests may have been optimized for performance only on Intel microprocessors. Performance
tests, such as SYSmark and MobileMark, are measured using specific computer systems, components, software, operations and functions.
Any change to any of those factors may cause the results to vary. You should consult other information and performance tests to assist you
in fully evaluating your contemplated purchases, including the performance of that product when combined with other products
