ASUS rolled out second-generation add-on Thunderbolt cards for its motherboards, the ThunderboltEX II series. It includes the single-port ThunderboltEX II, and the two-port ThunderboltEX II DUAL. The two are based on Intel's DSL5320 and DSL5520 chipsets, respectively, and support the Thunderbolt 2.0 standard, which offers 20 Gb/s of bandwidth over a single cable.

The cards aren't completely independent, and can't just be plugged into any motherboard with a PCI-Express 2.0 x4/x16 slot. It requires a special header that's used for timing, and low-level system interface, and optionally, an end-to-end DisplayPort (if you want to relay display from your graphics card through the common Thunderbolt pipe). A list of compatible motherboards can be found on the product page.
