Crossfire Bridge Interconnect Cable The HIS CrossFire Bridge Interconnect Cable connects two crossfire compatible video cards. Easily enable new native CrossFire on either x1950 Pro or x1650 XT by connecting two of the cards from the same product series (i.e. x1950 Pro with x1950 Pro or x1650 XT with x1650 XT) with two CrossFire Bridge Interconnects. The compositing engine combines the result of both cards to output a complete image.
