Difference between Thunderbolt and DisplayPort

What distinguishes Thunderbolt from DisplayPort?

  1. In May of 2006, the Video Electronics Standards Association (VESA) proposed the DP (DisplayPort) standard as a next-generation hd audio/video interface. The current version is DP1.2.
  2. The Mini DP and ThunderBolt interfaces are physically identical.
  3. Mini DisplayPort lacks the data transmission function (PCI) that is present in the ThunderBolt interface.
  4. ThunderBolt is a composite interface, which can be understood as it provides PCI-E to external devices (Computer graphics card, sound card, etc., connected to the CPU via the PCI slot), a feature which Intel fully exploited in developing the Thunderbolt interface, ThunderBolt = DP + PCI, that is, the lightning interface can be thought of as a combination of DisplayPort and the PCI bus. The display port (DP) is capable of sending PCI data along with audio and video signals to the monitor.
  5. Mini Displayport is a reduced-size variant of the original Displayport interface that only provides support for Display. For the Display-only cable, their purposes are identical; however, ThunderBolt is based on Mini Displayport, making ThunderBolt 2 the predecessor of ThunderBolt 3, and Mini Displayport the predecessor of ThunderBolt 2.
  6. There are now many displays and hard drive storage options that center around the ThunderBolt interface, which has replaced MiniDP on all new Apple Mac products.
