    Thunderbolt 3, 4, or 5 ports USB-C Thunderbolt 3, 4, or 5 connector. Thunderbolt 3 is a hardware interface developed by Intel. [75] It shares USB-C connectors with USB, supports USB 3.1 Gen 2, [76] [77] [78] and can require special "active" cables for maximum performance for cable lengths over 0.5 meters (1.5 feet). Compared to Thunderbolt 2 ...

    A specific USB-C mode may also be entered, where 5 V at nominal either 1.5 A or 3 A is provided. [65] A third alternative is to establish a USB Power Delivery (USB-PD) contract. In single-lane mode, only the differential pairs closest to the CC pin are used for data transmission. For dual-lane data transfers, all four differential pairs are in use.

    Classically there has been a 1:1 relationship between a USB endpoint and a buffer in system memory, and the host controller solely responsible for directing all data transfers. Streams changed this paradigm by providing a 1-to-many "endpoint to buffer" association, and allowing the device to direct the host controller as to which buffer to move.

    The SMBus clock is defined from 10 to 100 kHz while I²C can be 0–100 kHz, 0–400 kHz, 0–1 MHz and 0–3.4 MHz, depending on the mode. This means that an I²C bus running at less than 10 kHz will not be SMBus compliant since the SMBus devices may time out. Many SMBus devices will however support lower frequencies.
