It's not as simple as a "CPU newer than date X" cutoff -- Intel limits 
AVX support to their Xeon and Core brands only.  Their current-gen 
lower-end stuff (sold as Pentium, Celeron and Atom) doesn't support 
AVX of any flavor.  And they sell a _lot_ of those.

I think AMD's situation is a bit better, with all of their current 
processors supporting AVX, and only one (Family 16h) lacking AVX2.
