I see lots of different 802.11ac router speeds out there, I'd like to get something that fits the MBP speeds, is that 300+867, 450+1300 or something else?
Those results are all for the MacBook Air, here are the MacBook Pro results:
In these results the transfer speed is displayed as MB/s not Mb/s so if we convert it the rMBP reaches 534.64Mb/s in this Apple File Transfer test. It reaches greater speeds (800Mb/s) using iPerf which means Apples file transfer protocol is probably due an update for these newer faster networking technologies.
The reason for the low MacBook Air speed is due to it only having two Antennas. The Retina MacBook Pro and iMac which both have 802.11ac use three antennas to reach the full 1300 specification however real world use is obviously going to be lower.
