An investigation into the new MacBook Air's internals has revealed that Apple is using a new, relatively untested Thunderbolt chip. Nicknamed Eagle Ridge, it has two 10Gbps bidirectional lanes (40Gbps) where the Light Ridge chip in the iMac, MacBook Pro, and Mac mini has a full four. The part tracked down by AnandTech can only drive one display over Thunderbolt but is also much smaller and most likely cheaper, a key to fitting it into even the 11-inch, $999 Air.
