Thunderbolt also supports other peripherals that use the Thunderbolt standard which provides up to 10 Gbps of bandwidth in both directions. It lacks internal Ethernet and lacks Firewire and optical audio in/out as well.Compared to its predecessor, this model has a very similar external enclosure, although it has the aforementioned Thunderbolt port, a backlit keyboard, and is slightly heavier. Internally, however, it has a faster processor, architecture and RAM as well as improved wireless capabilities.
