At Computex, ASRock showed off their Z77 Extreme6/TB4 motherboard. Main attraction of this motherboard is its 4 channel dual thunderbolt ports. Four channels means that each port has two channels and each port can individually transfer data at 10 Gbps. Although ASRock claims that its world’s first 4 channel dual-port thunderbolt motherboard but GIGABYTE (GA-Z77X-UP5 TH)
already have one already selling for US $250 and ASRock haven’t even released their’s yet.
Everything else is pretty much identical to the Z77 Extreme6 (non-thunderbolt one) in terms of features. LGA1155 socket with support for Sandy Bridge and Ivy Bridge, two PCI Express 3.0 x16 slots, 7.1 channel Realtek ALC898, four SATA III 6 Gb/s and four USB 3.0 and gigabit LAN fall in the usual set of features.
Another feature, ASRock introduced in this motherboard is DP-in design. This allows you to connect a thunderbolt display to motherboard but still be able to use discrete GPUs horse power. A mini-DisplayPort to DisplayPort cable connects the discrete GPU to motherboard via a special DP-in port present at the back I/O panel.
This motherboard is expected to debut by the end of this month or start of next month.
