It allows up to 4 lanes of PCI Express 3.0 (32.4 Gbit/s) for general-purpose data transfer, and 4 lanes of DisplayPort 1.4 HBR3 (32.40 Gbit/s before 8/10 encoding removal, and 25.92 Gbit/s after) for video, [79] but the maximum combined data rate cannot exceed 40 Gbit/s; video data will be using all needed speed, limiting PCIe data. DP 1.2 ...
While the gross data rate equals 33.3 million 4-bit-transfers per second (or 16.67 MB/s), the fastest transfer, firmware read, results in 15.63 MB/s. The next fastest bus cycle, 32-bit ISA-style DMA write, yields only 6.67 MB/s .
Thunderbolt originally used the mDP connector and was only backward compatible to DP connections and did not support power transfer. The introduction of the Type-C connector in 2014 provided a connector that could support USB data connectivity and power transfer as well as DP connections. It also allowed the static sharing of bandwidth between ...

[44] [45] The architecture defines a method to share a single high-speed link with multiple end device types dynamically that best serves the transfer of data by type and application. During CES 2020, USB-IF and Intel stated their intention to allow USB4 products that support all the optional functionality as Thunderbolt 4 products.
In telecommunications, data transfer rate is the average number of bits ... Computer data interfaces Thunderbolt 2: 5,000 MB/s 40,000,000,000 5,000,000,000
It preserves existing USB 3.1 SuperSpeed and SuperSpeed+ data modes and introduces two new SuperSpeed+ transfer modes over the USB-C connector using two-lane operation, doubling the signalling rates to 10 and 20 Gbit/s (raw data rate 1 and ~2.4 GB/s). USB 3.2 is only supported by USB-C, making previously used USB connectors obsolete.
A data packet consists of the PID followed by 0–1,024 bytes of data payload (up to 1,024 bytes for high-speed devices, up to 64 bytes for full-speed devices, and at most eight bytes for low-speed devices), [12] and a 16-bit CRC. There are two basic forms of data packet, DATA0 and DATA1. A data packet must always be preceded by an address ...
