Thunderbolt 1.2 only identifies the possibility of 60 Hz refresh rates on the bus.
Thunderbolt 2.
60Hz.

With 10.9.3 Apple has not only broadly increased support for 4K displays, but also enabled 60Hz output to 4K displays on more systems. The Dell UP2414Q, a 24" 3840 x 2160 display, is now properly supported by OS X and Macs that can drive it at its native resolution...
Along with expanded display support, some new Macs also get the ability to drive 4K panels at 60Hz. By some I mean one: the 15-inch MacBook Pro with Retina Display from late 2013. This is the Haswell refresh of the rMBP15, and it remains the only portable Mac capable of driving a 4K panel at 60Hz over either of its two miniDP ports (HDMI is limited to 30Hz)...
Obviously the new Mac Pro works just fine with these displays as well.
