I think he means the 11" or 13" Air and the "12" is just a typo...
If that's what you meant then there isn't much of a difference. The Pro is very slightly faster as it's got a faster CPU and GPU, but the main factor that determines how fast a machine boots up is the SSD/HDD and all of Apple's current laptops share the same SSD's.
From off, it takes my rMBP about 5-7 seconds until my password screen shows up. Reboot takes a little longer but the extra time is in the shut down process. About 20 seconds total.
Don't notice much difference between the Air and rMBP(have both in my house)

Similar question has come up before but I can't find the thread.
Anyway, do a restart and Click on "Reopen windows when logging back in".
Then do it again with the "Reopen..." box unchecked.
Don't know why but it sure improved my restart and shutdown times.
Hope it helps.
