Intel announced Thunderbolt 5, promising 80 Gbps of bi-directional bandwidth, and with Bandwidth Boost up to 120 Gbps for displays.
Thunderbolt 5, will provide up to three times more bandwidth than the best existing connectivity solution, is based on industry standards – including USB4 V2 – and will be broadly compatible with previous versions of Thunderbolt and USB.
Thunderbolt 5 builds upon Thunderbolt 4 in several ways, including:
- Two times the total bi-directional bandwidth; Bandwidth Boost provides up to three times the throughput for video-intensive usage, up to 120 Gbps.
- Double the PCI Express data throughput for faster storage and external graphics.
- Built on industry standards including USB4 V2, DisplayPort 2.1 and PCI Express Gen 4; fully compatible with previous versions.
- Double the bandwidth of Thunderbolt Networking for high-speed PC-to-PC connections.
- Utilizes a new signaling technology, PAM-3, to deliver these significant increases in performance with today’s printed circuit boards, connectors and passive cables up to 1 meter.
- Computers and accessories based on Intel's Thunderbolt 5 controller, code-named Barlow Ridge, are expected to be available starting in 2024.
