Y has been around for years, and so has K, H / HQ, M, T, U designations. The newest designations (F for GPU-free) haven't really changed the meaning of the old ones.
Xeon has its own naming convention that was changed maybe 5ish years ago? (Whenever they went from E3 / E5 / E7 designation to Xeon Bronze / Silver / Gold / Platinum). There are also naming schemes for the Atom-line, but these aren't commonly bought by consumers.
