6ft USB4 Type-C Thunderbolt 3 (20Gbps 100W PD 8K) Braided CableThe USB 4 standard introduces speeds never before supported using USB technology, combined with Thunderbolt inch3inch technology allows this cable to support speeds to 20Gbps (for this 6 foot length), video resolutions to 8K, and Power Delivery (PD) to 100Watts (20V at 5A). The key features are support for USB4 protocol and data rates, a minimum bandwidth requirement of 32 Gbit/s for PCIe link, support for dual 4K displays (DisplayPort 1.4) and Intel(TM) VT-d-based direct memory access protection to prevent physical DMA attacks.
Another major improvement is that TB now supports Thunderbolt Alternate Mode USB hubs (inchMulti-port Accessory Architectureinch), and not just daisy chaining. Those hubs are backwards compatible with Thunderbolt 3 devices and can be backwards compati
