Direct media interface

The Direct Media Interface (DMI) is the link between an Intel Northbridge and an Intel Southbridge on a computer motherboard.DMI shares many characteristics with PCI-E, using multiple lanes and differential signalling to form a point-to-point link.

      Intel Atom n2800 DMI      - 2.5 GT/s
      AMD E-350 DMI              - 2.5 GT/s
      Core i5 (2nd gen) DMI      - 5 GT/s

DMI provides 10Gb/s each direction using a x4 link. First generation Core i3/i5/i7 and Atom series supported DMI. DMI 2.0 (introduced in 2011) doubles the transfer rate to 20Gb/s with a x4 link. Second generation Core i3/i5/i7  series supports DMI 2.0. For more details of DMI for specific chipset visit DMI in Wikipedia or click through to find the required details on Ark Intel website.
