GIGABYTE announced that it's enabling 40 Gb/s Thunderbolt 3 support on select boards that have 20 Gb/s Thunderbolt 2 support, with a mere firmware update. It turns out that the Thunderbolt controllers on the company's Z170X-Gaming G1, Z170X-Gaming GT, and Z170X-Gaming 7 motherboards physically support Thunderbolt 3, but due to a lack of certification, its support was withheld, and bandwidth limited to 20 Gb/s.
What's more, these boards support the Thunderbolt protocol over USB 3.1 type-C, at lowered bandwidth, besides its traditional Thunderbolt/mini-DisplayPort connector at rated bandwidth. This should help with the new generation of Thunderbolt daisy-chaining docks that support USB type-C connections. To get the latest firmware, all you need to do is update your board's BIOS to the latest one on GIGABYTE's website.
