That's been the way of it since at least the first Pentiums, and probably 
earlier. It makes perfect sense - here's why:

When a line first begins making processors, the % of processors that will 
pass all the highspeed tests low, while the % that will pass the lower speed 
tests is greater. So they are priced and spec'd so that the entire run is 
(hopefully) bought up. If they priced 'em all the same, there would be a shortage of 
highspeed processors and a surplus of lowspeed ones.

As the manufacturing process matures, the yield of highspeed processors 
increases. 

The really good news is that *all* of them are tested so thoroughly that the 
possibility of a bad one getting through the process is very low.

the microprocessor tester. Without the ability to automatically and decisively 
test the processors, they would be too unreliable for practical use.
