GIGABYTE showed off some of its first Ultra Durable 5 motherboards, which included its first Thunderbolt-equipped ones, the Z77X-UP4 TH and the Z77X-UP5 TH. The two are slated to be notches above the current-generation Z77X-UD3H and Z77X-UD5H, respectively. Their most striking feature is the Thunderbolt interface, which gives high-bandwidth devices (such as DAS) access to 10 Gb/s of bandwidth. The Thunderbolt interface is also wired to the Intel Flexible Display Interface (FDI), which routes the Intel HD 4000/2500 series graphics of the processor through a common Thunderbolt + mini-DisplayPort, which can then be daisy-chained between 6 devices, including a monitor. The two also feature high-grade CPU VRM, which utilize new high-current chokes and PowIRstage IR3550 driver-MOSFETs, and a VRD12-compliant VRM controller, also made by IR. The Z77X-UP4 TH and the Z77X-UP5 TH are otherwise similar to the UD3H and UD5H, respectively, in terms of other features.
