GIGABYTE is the first to bring Thunderbolt 3 to the desktop PC by launching the GIGABYTE Z170X-UD5 TH motherboard with support for the 6th Generation Intel Core processors. Powered by Intel?s own Thunderbolt controller the new Thunderbolt 3 protocol, which is available over two USB Type-C connectors on the back I/O of the GIGABYTE Z170X-UD5 TH, brings a single-wire bandwidth of up to 40 Gb/s. This increase in bandwidth is also accompanied with support for different protocols such as DisplayPort 1.2 and USB 3.1, which is backwards compatible with USB 3.0 and USB 2.0, opening up a world of new possibilities.

Support for DisplayPort 1.2 makes Thunderbolt 3 a must have for any enthusiast. The Z170X-UD5 TH is able to support two displays in 4K resolution at 60 FPS or one display in 5K resolution. In addition, Thunderbolt 3 over USB Type-C has industry-first features such as Power Delivery 2.0, and the ability to daisy-chain up to 12 devices thanks to the Z170X-UD5 TH?s dual USB Type-C ports.

The GIGABYTE Z170X-UD5 TH packs in many other features such as the cFosSpeed internet acceleration software over the Intel GbE LAN which will help deliver better network responsiveness and improve network performance. For optimum graphics, the Z170X-UD5 TH features support for multiple graphics cards in SLI or Crossfire configuration and includes GIGABYTE?s Ultra Durable PCIe one piece metal shielding. Additionally, GIGABYTE?s Z170X-UD5 TH supports the latest NVMe protocol over the M.2 connector which allows high-performance storage devices, with the use of GIGABYTE?s M.2 to U.2 adaptor.
