Well, would you look at that. The eagle-eyed folks over at AnandTech have discovered that the Thunderbolt ports on the new MacBook Airs, a key addition to the refreshed laptops, aren't the same as the Thunderbolts we've come to know in the iMac, MacBook Pro and Mac Mini. The Air's version has been shrunk, presumably to fit inside the computer's svelte chassis, and is as a result is about half as powerful.
According to AnandTech, instead of supporting 4 bidirectional 10Gbps channels and up to two DisplayPort monitors like the larger Thunderbolts, the MBA chip can handle two bidirectional 10Gbps channels aand one DisplayPort. The smaller Thunderbolts could soon find there way into other tiny tech as well.
