Macs are not updated annually - some lines are updated more frequently, and others less frequently.

We know that we're up to the iPhone 6, so an iPhone 5S must be one year older and the 5 must be two years older. iOS devices have been updated annually almost perfectly (the iPad 3 is the only exception I can think of), so there's not much need to identify it with the year.
