The 2013 and all new macs except for the new macbook have thunderbolt 2 ports with 20 Gbit/s thunderbolt. That is a huge difference when dealing with 4k. USB-C will never handle that. Thunderbolt 3 will be released this year (Alpine Ridge) with PCIe 3.0 with backwards compatability to thunderbolt 2 and 1 and will offer 40Gbit/s (5GBs). And the ability to drive two external 4k displays at 60hz or 1 5k. Intel is on track to release Skylake architecture chips this year.
