MSI equipped the Z77A-GD80 with the groundbreaking Thunderbolt™ technology. Thunderbolt™ is the fastest data connection available for your PC, running at 10Gbps. Thunderbolt™ technology delivers two communications methods, or protocols, on a single cable: PCI Express for data transfer and DisplayPort for displays. MSI has integrated the Thunderbolt controller on the mainboard, ensuring that Thunderbolt is a hassle-free solution that not requires additional cards, cables and configuration issues because external Thunderbolt controllers steal bandwidth from other devices. Thunderbolt is an easy technology and should not add to your PC complexity!
